TL;DR

Kungani i-RFQ ye-Ground Rod Yehluleka Ekukhipheni Izinto Ezingafuneki

Njalo ngonyaka, amaqembu okuthenga kuzo zonke izinhlaka zikagesi, ezokwakha, kanye nezokuxhumana abeka izinkulungwane zama-oda okuthenga ezinduku zomhlabathi. Amaningi alawo ma-oda afika endaweni yokwamukela kodwa enqatshwa, ahlukaniswe, noma aphoqwe ukuba aphinde alungiswe ngokuphuthumayo. Imbangela eyinhloko cishe ayikaze ibe umhlinzeki ongathembekile. Esikhundleni salokho, kuyisicelo esingaphelele sekhotheshini esishiya imininingwane ebalulekile ivulekele ukuhunyushwa. Lapho i-RFQ yenduku yomhlabathi ishiya ukujiya kwe-copper cladding, i-thread pitch, noma ukubekezelelana kokuqina, umhlinzeki ugcwalisa igebe ngomkhiqizo wakhe ojwayelekile womnotho, futhi lowo mkhiqizo awuvamile ukuhambisana nenhloso yomklamo wonjiniyela.

Umthelela wezezimali uyanda ngokushesha. Ukuthunyelwa okwenqatshiwe kubangela uku-oda kabusha kwezimpahla ngendiza ngamanani aphezulu, ukubambezeleka kweshejuli yephrojekthi kulinganiswa ngamaviki, kanye nezindleko zomsebenzi wasensimini zokuphinda kuqhutshwe noma ukufaka esikhundleni izinduku ezingalingani. Kwesiteshi esikhulu nomaukuvikelwa kombaniUma amaphrojekthi enziwe kabusha, izindleko zoku-oda kabusha okukodwa zingadlula inani le-oda lokuqala. Isixazululo siwuhlu lokuhlola oluhlelekile oluvala yonke igebe lokungacaci ngaphambi kokuba i-RFQ isuke edeskini lakho. Ukuthi ukufakwa kusebenzela izinga lokusetshenziswa yiniuhlelo lokumba umhlabanoma isakhiwo sezentengiselwanoukuvikelwa kombaniinethiwekhi, isiyalo semininingwane sifana.

Lesi sihloko sethula imininingwane eyisishiyagalolunye yenduku yomhlaba ethathwe ekuhlulekeni kokuthengwa kwangempela kanye nesipiliyoni seminyaka engu-17 semboni yethu kanye nemibiko yokwehluleka kwensimu. Imininingwane ngayinye ikhuluma ngomthombo obhaliwe wengozi yokuhleleka kabusha, kusukela ekwakhiweni kwezinto kanye nokubekezelelana kobukhulu ngokusebenzisa isitifiketi, ukupakisha, kanye nokwenza ngokwezifiso. Kungakhathaliseki ukuthi uyithola kuphiizinduku zomhlabathi ezimbozwe ngethusi zokufaka umhlaba ezitshalweni zikagesinoma izinduku ezifakwe i-galvanized zokuthuthukiswa kwezindlu, lezi zinsimu eziyisishiyagalolunye zizoguqula i-RFQ yakho isuke ekuphenyweni okungacacile ibe yidokhumenti yokucacisa ebophayo.

Induku yomhlabathi embozwe ngethusi eyenzelwe ukuvikela umbani kanye nokusetshenziswa kwesistimu yokumba umhlaba.

I-Spec 1 — Ukwakheka Kwezinto kanye Nezindinganiso Zokumboza Ngethusi

Ukwakheka kwezinto ezibonakalayo kuyincazelo eyodwa ebaluleke kakhulu kunoma iyiphi i-RFQ yenduku yomhlabathi. Induku yomhlabathi kumele ihambise ugesi wephutha emhlabeni ngokumelana okuncane ngenkathi imelana nokugqwala kwamakhemikhali enhlabathini amashumi eminyaka. Izinhlelo ezimbili zezinto ezibonakalayo emakethe yinsimbi embozwe ngethusi kanye nensimbi eshisiwe eshisayo. Izinduku ezimbozwe ngethusi zibopha ungqimba lwethusi oluhlanzekile kakhulu phezu kwensimbi enekhabhoni ephezulu, zihlanganiseukuhanjiswa okuhle kakhulu kwethusingamandla ensimbi okusebenza ngomshini.I-GalvanisedIzinduku zithembele embozweni we-zinc ukuze zivikele ukugqwala kodwa zinikeza ukuhanjiswa okuphansi kunethusi.

Ngezinduku zomhlabathi ezimbozwe ngethusi, chaza ubukhulu bengqimba yethusi obuncane ngamamilimitha.insimbi embozwe ngethusiIzinga lokwakha elamukelwa ezimakethe eziningi zomhlaba wonke liwubukhulu bethusi obungu-0.254 mm, njengoba kubhekiselwe ku-UL 467. Ezindaweni ezinomhlabathi onamandla njengezindawo ezisogwini, izitshalo zamakhemikhali, noma inhlabathi ene-sulfate ephezulu, thuthukisa isidingo sibe yi-0.5 mm kuya ku-1.0 mm yokubopha ithusi. Futhi chaza ubumsulwa bethusi ngamaphesenti angu-99.95 noma ngaphezulu. Lezi zinombolo ezimbili zodwa zisusa umthombo ovame kakhulu wokwehluleka kwenduku ngaphambi kwesikhathi.

Ukwakheka kwensimbi eyinhloko nakho kubalulekile. Insimbi enekhabhoni ephezulu enamandla okunamathela okungenani angu-580 N ngemilimitha yesikwele inikeza ukuqina okudingekayo ekushayeleni okujulile ngaphandle kokugoba. Uma iphrojekthi yakho idingaukuhanjiswa kukagesi okuphezulu kakhulu kwethusingezicelo ezibalulekile zokumba umhlaba, bheka i-ASTM B452 nomaindinganiso kazwelonke efaneleku-RFQ yakho. Ngokuhlanganisa ubumsulwa bethusi, ubukhulu bethusi, izinga lensimbi, kanye nezindinganiso ezifanele zibe yibhulokhi eyodwa yokucaciswa, awuniki umhlinzeki indawo yokufaka izinto eziphansi futhi awuniki sizathu sokuthunyelwa okungahambisani.

Embonini yethu, ubukhulu be-copper cladding buqinisekiswa kuwo wonke amaqoqo ngaphambi kokuthunyelwa kusetshenziswa imishini yokulinganisa ye-ultrasonic elinganiswe ngokwezindinganiso zomhlaba wonke. Le nqubo ibamba noma yikuphi ukushintsha kwesendlalelo sethusi okungaphuthelwa ukuhlolwa okubonakalayo kuphela, okuqinisekisa ukuthi induku ngayinye ku-oda lakho ihlangabezana nencazelo yobukhulu obuncane eshiwo ku-RFQ.

I-Spec 2 — Ububanzi, Ubude, kanye Nokubekezelelana Okulinganayo

Ukucaciswa kobukhulu kubonakala kuqondile, kodwa kungumthombo wesibili ovame kakhulu wokuhleleka kabusha kwenduku yomhlaba. Ukudideka kuvela ngoba ububanzi benduku yomhlaba buvela kokubili kumayunithi e-metric kanye ne-imperial kuma-RFQ amaningi esiwatholayo. Induku engu-5/8-intshi ihambelana cishe no-15.9 mm, kodwa ububanzi benduku yangempela evela kubakhiqizi abahlukene bungaba phakathi kuka-14.2 mm kuya ku-16 mm kuye ngokuthi ilandela ubukhulu obujwayelekile noma obuqediwe. Uma i-RFQ yakho ithi "ama-intshi angu-5/8" kuphela ngaphandle kwebhendi yokubekezelelana kwe-metric, umhlinzeki angathumela izinduku ezingalingani nezesekeli zakho zokuxhuma ezicacisiwe noma amathuluzi okushayela.

Izidingo zobude zinengozi efanayo. Ubude benduku yomhlabathi ejwayelekile busukela kumamitha angu-1.2 (4 feet) kuya kumamitha angu-3.0 (10 feet). I-RFQ yakho kumele isho ubude obujwayelekile kanye nokubekezelelana okwamukelekayo, isibonelo amamitha angu-2.4 ngaphezulu noma ngaphansi kuka-10 mm. Izinduku ezimfushane zishibhile ukuzikhiqiza nokuthumela, ngakho-ke abahlinzeki abasebenza emaphethelweni amancane bangase bafinyelele ekugcineni okuphansi kobubanzi bokubekezelelana obungacacisiwe. Ekufakweni okujulile enhlabathini enokumelana okuphezulu, isentimitha ngalinye lobude benduku libalulekile ekufinyeleleni inani lokumelana komhlaba eliqondiwe elichazwe unjiniyela wephrojekthi.

Ukuqondakala kuyisici sesithathu esinganakwa. Induku ephambuka ngaphezu kwe-1 mm ngemitha kusuka emugqeni oqondile izovimba ngesikhathi sokushayela nge-pneumatic, yonakalise izintambo zokuxhuma, futhi idinga ukulungiswa kwensimu ngesandla. Cacisa iphutha elikhulu lokuqondakala, njenge-1 mm ngemitha noma ngaphansi, futhi idinga ukuthi umhlinzeki afake idatha yokuqondakala embikweni wakhe wokuhlola ikhwalithi.Induku yomhlaba ye-SS enentambo engu-5/8-intshi evela kuShibangikhiqizwa ngokubekezelela ukuqondeka okungu-1 mm ngemitha noma ngaphezulu, okwenza ifaneleke ukusetshenziswa kwe-deep-drive ngaphandle kokulungiswa kwensimu.

I-Spec 3 — Uhlobo Lwentambo kanye Nesixhumi Esibonakalayo Semishini

Ukucaciswa kwentambo kungumlindi wesango lokusebenza kahle kokufakwa kwensimu. Lapho izinduku zomhlabathi kumele zishayelwe zijule kunobude benduku eyodwa, izesekeli zokuxhumanisa zijoyina izinduku ezimbili noma ngaphezulu kusukela ekuqaleni kuya ekugcineni. Uma uhlobo lwentambo endukwini lungahambisani ne-coupler, ithimba lokufaka alikwazi ukuzixhuma. Umphumela uba ukumiswa kwephrojekthi kuyilapho izinduku zokufaka eziphuthumayo zitholakala, ngokuvamile ngamanani okuthutha emoyeni. Lesi simo siphindaphinda kuwo wonke amaphrojekthi omhlaba ngoba ama-RFQ avame ukushiya imininingwane yentambo, ecabanga ukuthi umhlinzeki uzolandela indinganiso yendawo.

Cacisa indinganiso yentambo ngokucacile: i-UNC (Unified National Coarse) yamaphrojekthi aseNyakatho Melika, i-ISO metric yamaphrojekthi aseYurophu nase-Asia, noma i-BSW yokufakwa kwe-British-standard standard endala. Faka i-thread pitch, uhlobo lokulingana, kanye nobude bentambo. Ngenduku yomhlaba engu-5/8-intshi, intambo evamile ye-UNC ingu-5/8-11, okusho ukuthi izintambo ezingu-11 nge-intshi ngayinye. Sho ukuthi udinga izintambo ezisikiwe efektri noma izintambo ezisikiwe ensimini, bese uqinisekisa ukuhambisana ne-adaptha yethuluzi lakho lokuhlanganisa elikhethiwe kanye ne-adaptha yethuluzi lokushayela.

Ngale kohlobo lwentambo, chaza i-geometry yesihloko senduku. Izinduku eziphansi zitholakala ngezindlela ezintathu ezijwayelekile zokuma kwesihloko: ezikhombayo zokushayela ngesandla kanye ne-pneumatic, ezisicaba (iplatifomu) yezimo zenhlabathi enamatshe lapho isihloko esicijile singaphambuka khona, kanye nezinontambo zokwandisa ukuxhuma. Uma iphrojekthi yakho ihilela ukushayela endaweni ehlanganisiwe noma ehlanganisiwe enamatshe, isihloko esicijile esinokwelashwa kwendawo eqinile kunciphisa isikhathi sokufakwa kanye nomonakalo wenduku.induku yomhlabathi embozwe ngethusi isukela eShibanginikeza izinhlobo ezinezintambo, eziyisicaba, nezicijile kuwo wonke ububanzi obusukela ku-14.2 mm kuya ku-25 mm, okuvumela amaqembu okuthenga ukuthi afane ne-geometry yesihloko nezimo zendawo ngaphandle kokushintsha abaphakeli.

I-Spec 4 — Amandla Okuqina, Ukuqonda, kanye Nokusebenza Kwesakhiwo

Imininingwane yokusebenza kwesakhiwo ivikela iphrojekthi yakho ezindleleni ezimbili zokwehluleka: ukugoba kwenduku ngesikhathi sokufakwa kanye nokuqhekeka kwenduku ngaphansi komthwalo wokuzamazama komhlaba noma weqhwa.Amandla okudonsakuyisibonakaliso esiyinhloko sekhono lenduku lokubekezelela ukushaywa kwesando okuphindaphindiwe komshayeli womoya ngaphandle kokushintsha noma ukuqhekeka. Ezindongeni zomhlabathi ezimbozwe ngethusi, amandla amancane okudonswa angu-580 N ngemilimitha yesikwele yisilinganiso esimisiwe semboni. Uma i-RFQ yakho ingasho le nombolo, umhlinzeki angasebenzisa insimbi esezingeni eliphansi edlula ekuhlolweni okubonakalayo kodwa yehluleke ngaphansi kokucindezeleka kokushayela.

Ukuqonda kuthinta ngqo ukusebenza kokushayela. Induku enephutha lokuqonda elingaphezu kuka-1 mm ngemitha izophambuka kancane kancane endleleni ehlosiwe yembobo njengoba ingena ijule. Enhlabathini ethambile lokhu kudala imbobo egobile enciphisa ukuxhumana komhlaba okuphumelelayo. Enhlabathini eqinile noma enamatshe, induku ibopha etsheni futhi ayikwazi ukuqhutshwa iye ekujuleni okugcwele. Cacisa ukuqonda njengokubekezelelana ngemitha, hhayi ukubekezelelana kobude obuphelele, ngoba induku engamamitha amathathu ingaqoqa ukuphambuka okungu-3 mm esicongweni noma ngabe ihlangabezana nesilinganiso sobude obuphelele esingu-3 mm esilinganisa ukubekezelelana kulo lonke ubude.

Iukusekela ngogesiUmsebenzi wenduku uncike nasekugcineni ukuthintana kwenhlabathi okuseduze kuyo yonke ubude bayo. Induku egobile idala izikhala zomoya phakathi kobuso benduku kanye nokufakwa kwayo emuva, okwandisa ukumelana komhlaba. Ekufakweni okubalulekile njengeziteshi ezincane kanye nezikhungo zedatha, ithimba lethu lobunjiniyela lihlose ukumelana komhlaba ngaphansi kwama-ohm angu-5, futhi yonke imithombo yokumelana okwandisiwe kumele isuswe. Ngokucacisa amandla okudonswa kanye nokuqondile njengezindlela zokudlula noma zokwehluleka ngezindlela zokuhlola ezibhaliwe, i-RFQ yakho iqinisekisa ukuthi induku ezilethwayo zisebenza kokubili ngomshini nangogesi kusukela ngesikhathi zingena enhlabathini.

Ukwenza ngokwezifiso kusuka ekumakisheni okulula kwelebula yangasese kuya kumajiyometri enduku enziwe ngokwezifiso ngokugcwele, ukuhlanganiswa kwe-alloy okuyimfihlo, noma ukucushwa kokupakisha okuqondene nephrojekthi ethile. Uma i-RFQ yakho ingabuzi ngezinketho zokwenza ngokwezifiso, umhlinzeki uzocaphuna umkhiqizo wabo wekhathalogi ejwayelekile, futhi uzophuthelwa amathuba okunciphisa isikhathi sokufakwa kwensimu, ukuthuthukisa ukubonakala komkhiqizo, noma ukuhlanganisa uchungechunge lwakho lokuhlinzeka ngomkhiqizo ohambisana nomkhiqizi oyedwa oguquguqukayo.

Izinketho ezivamile zokwenza ngokwezifiso zifaka phakathi ama-logo enkampani aqoshwe nge-laser noma agxivizwe nge-inki kanye nezinombolo zezingxenye endukwini ngayinye, amabhande ombala ngokwezifiso ukuze kube lula ukuhlonza uhlobo lwenduku nobude bayo, ubude obungajwayelekile obunqunywe ngokwencazelo yephrojekthi yakho, kanye nezindlela zokufaka izintambo ezizimele ukuze kuhambisane nohlelo lwesikhathi esidlule. Kumaphrojekthi amakhulu engqalasizinda, cabanga ngokucela amaphuzu okushisela e-exothermic afakwe efektri, ama-clamp omqhubi anamathiselwe ngaphambilini, noma izesekeli zokuxhuma ngokwezifiso ezifanelana nencazelo yenduku yakho. Lokhu kwenza ngokwezifiso okusetshenziswe efektri kususa izinyathelo zomsebenzi wasensimini futhi kunciphisa ingozi yamaphutha okufakwa.

Amakhono e-ODM anwebeka ekwenzeni ngokwezifiso izinto kanye nokugqoka. Uma iphrojekthi yakho idinga ingxube ethile ye-alloy yethusi ukuze kuthuthukiswe ukumelana nokugqwala noma ukugqoka nge-zinc-aluminium esikhundleni se-galvanizing ejwayelekile, umenzi onolwazi angakha ukwakheka ngokwezifiso futhi akuqinisekise ngokumelene nezidingo zakho zokuhlola. Iminyaka engaphezu kwengu-17 ye-Xinchang Shibang yokukhiqiza umkhiqizo oyisisekelo isekela amaphrojekthi e-OEM kanye ne-ODM kulo lonke uhla lwawo lomkhiqizo. Faka isitatimende esicacile ku-RFQ yakho sokuthi uyazamukela iziphakamiso zokwenza ngokwezifiso, ubhale izidingo zakho zokwenza ngokwezifiso ezithile, bese ucela umhlinzeki ukuthi anikeze ukuhlolwa kokusebenziseka ngokwezifiso kanye namanani ngempendulo yakhe yesilinganiso.

Induku yokumisa insimbi embozwe ngethusi eyenzelwe iziteshi zikagesi kanye nezinhlelo zokumisa umhlaba zesiteshi esincane.

Amaphutha Avamile E-RFQ Abangela Uku-oda Kabusha Okubiza Kakhulu

Isisusa sokuhlela kabusha esivame kakhulu esisibona kuma-oda ethu okuthumela ngaphandle ukucacisa uhlobo lomkhiqizo ngaphandle kokucacisa imingcele yokusebenza. Ukubhala "induku yomhlaba eboshwe ngethusi, 5/8 intshi, 8 amamitha" ngaphandle kokusho ukujiya kwethusi, amandla okunamathela, uhlobo lwentambo, noma izidingo zesitifiketi kunikeza umhlinzeki ukuzikhethela okuphezulu kanye nengozi enkulu yomthengi. Umhlinzeki uzocaphuna induku yakhe ebiza kakhulu ehambisana kahle nalawo mapharamitha amathathu angacacile, futhi umthengi uzothola lapho ehlolwa ukuthi izintambo azihlangabezani nezidingo zangempela zonjiniyela wephrojekthi.

Iphutha lesibili elivamile ukuxuba amayunithi angobukhosi kanye nama-metric ngaphandle kokuguqulwa. Ukusho ububanzi ngamasentimitha nobude ngamamitha kudala ukungaqondakali lapho umhlinzeki esebenza ohlelweni olulodwa kanti umhloli wekhwalithi yomthengi usebenza kolunye. Njalo nikeza imininingwane yamayunithi amabili ngeyunithi eyinhloko ecacile kanye nenothi lokuguqulwa. Iphutha lesithathu ukuphatha i-RFQ njengombhalo wentengo kuphela kunokuba kube yincazelo yobuchwepheshe. Ukuthumela i-imeyili elula ucela "intengo engcono kakhulu ezindongeni zomhlabathi" ngaphandle kokunamathisela ishidi lencazelo kuqinisekisa ukuthi ikhotheshini oyitholayo izoba ngeyomkhiqizo oshibhile womhlinzeki, hhayi umkhiqizo odingwa yiphrojekthi yakho.

Iphutha lesine ukushiya izidingo zokupakisha nezokuthutha. Izinduku ezichazwe kumazinga aqinile zisengafika zonakele uma imininingwane yokupakisha ingekho. Iphutha lesihlanu ukwehluleka ukucacisa izidingo zamadokhumenti. Ngaphandle kohlu lwamadokhumenti oluchaziwe ku-RFQ, umhlinzeki uthumela izinduku ngaphandle kwemibiko yokuhlola, izitifiketi, noma idatha yokuhlola, futhi awunaso isisekelo esiqondile sokwamukela noma ukwenqaba ukuthunyelwa. Iphutha ngalinye kulawa mahlanu lilandela iphethini efanayo: umbhali we-RFQ wayecabanga ukuthi umhlinzeki uzochaza ulimi olungacacile ngendlela umthengi ayeyihlosile. Imininingwane ehlelekile isusa lowo mbono ngokuphelele.

Indlela Yokwakha I-RFQ Yakho Elandelayo Yenduku Yomhlabathi

I-RFQ yenduku yomhlabathi esebenzayo ilandela ifomethi ehlelekile engashiyi sikhala semininingwane. Qala ngebhulokhi yekhanda ekhomba igama lephrojekthi, indawo yesayithi, ikhodi kagesi esebenzayo, kanye neshejuli yokulethwa. Landela ngethebula lemininingwane yezinto ezibonakalayo elibala uhlobo lwenduku, ububanzi, ubude, ukujiya kwe-copper cladding, ubumsulwa bethusi, ibanga lensimbi, kanye ne-tip geometry. Engeza ibhulokhi yokusebenza echaza amandla okudonsa, ukubekezelelana kokunemba, kanye nokuphila kwenkonzo okungenani. Faka ibhulokhi yesitifiketi ebala izitifiketi ezidingekayo kanye nemibhalo edingekayo okufanele ithunyelwe.

Ingxenye yesibili ye-RFQ ikhuluma ngemigomo yezentengiselwano kanye neyokuthutha. Cacisa ukucushwa kokupakisha, ubukhulu bephalethi, izidingo zokuvikela umswakama, kanye nemikhawulo yokuphatha imbobo ethile. Yisho ama-Incoterms, imbobo yokulayisha, imbobo yokuya kuyo, kanye nezinsuku zokulethwa ezidingekayo zesigaba ngasinye sokuthunyelwa. Faka okulindelwe yi-MOQ, inani le-oda eliqondiwe, kanye nesakhiwo samanani. Vala ngesigaba se-OEM noma se-ODM esibala noma yiziphi izidingo zokwenza ngokwezifiso futhi simema umhlinzeki ukuthi aphakamise ezinye izindlela ezengeziwe zenani. Lesi sakhiwo esinezingxenye ezimbili siqinisekisa ukuthi yonke impendulo yekhotheshini oyitholayo iyafana ngokobuchwepheshe futhi ingasetshenziswa ngokwezentengiselwano.

Ngaphambi kokukhipha i-RFQ, yibukeze nonjiniyela wakho wephrojekthi, umphathi wekhwalithi, kanye nomxhumanisi wezokuthutha ukuqinisekisa ukuthi yonke imininingwane iyadingeka, yonke into ebekezelelwayo iyatholakala, futhi yonke imininingo yokulethwa ingokoqobo. I-RFQ ehlelwe kahle yenza okungaphezu kokuvimbela uku-oda kabusha. Isungula isisekelo sobuchwepheshe sokuhlolwa okungenayo, idala uhlaka lwenkontileka lwezimangalo zekhwalithi, futhi ibeka ithimba lakho lokuthenga njengomthengi ochwepheshe, oqhutshwa imininingwane abakhiqizi abazimisele abafuna ukusebenza naye. Uma usukulungele ukuthola izinduku zomhlaba zephrojekthi yakho elandelayo, vakashela i-ikhathalogi ephelele yenduku yomhlabathi kanye nenduku yomhlabathi evela ku-Xinchang Shibangukuze ubuyekeze imininingwane etholakalayo, noma uxhumane nethimba labo lokuthengisa ukuze nixoxe ngezidingo zephrojekthi yakho ngqo.

Izimo Zokusetshenziswa: Indlela Imininingwane Exazulule Ngayo Izinselele Zangempela Zephrojekthi

Inkampani kagesi eSaudi Arabia ya-oda izinduku ezimbozwe ngethusi ezinongqimba lwethusi oluyi-0.5 mm okungenani ukuze kufakwe igridi yokumisa phansi esiteshini esincane e-Arabian Desert. Inhlabathi yesihlabathi, i-alkaline kanye namazinga okushisa adlula ama-degree Celsius angu-50 kusheshisa ukugqwala ezindongeni ezijwayelekile ezimbozwe nge-galvanised eminyakeni embalwa. Ngokucacisa ubukhulu obuthuthukisiwe be-copper cladding kanye nokudinga idatha yokuhlolwa kwe-ASTM B117 salt spray, ithimba lokuthenga liqinisekisile ukuthi izinduku zizomelana ne-chemistry yenhlabathi yasehlane enamandla futhi zigcine ukumelana okuphansi komhlabathi phakathi neminyaka engu-40 yomklamo wephrojekthi.

Inkampani yezokuxhumana ePhilippines ikhethe izinduku zomhlaba ezinezintambo ezinezinsika zezintambo ezihambisana ne-UNC zenethiwekhi yokufakwa kwemibhoshongo yesiteshi esiyisisekelo kulo lonke elaseLuzon naseVisayas. Isimo sezulu esishisayo siletha umswakama oqhubekayo ngaphezu kwamaphesenti angu-80 kanye nezimvula zemvula zesizini ezigcwalisa inhlabathi izinyanga eziningi ngesikhathi, okudala izimo ezifanele zokugqwala okusheshayo kanye nokumelana komhlaba okuphezulu. Ngokucacisa uhlobo lwentambo kanye nokuhambisana kokuxhuma ku-RFQ kanye nobukhulu be-copper cladding, inkampani yaqeda ukulungiswa kabusha kwensimu okubangelwa izixhumi ezingalingani futhi yaqinisekisa ukuthi indawo ngayinye yombhoshongo ihlangabezana nomkhawulo wokumelana komhlaba odingekayo kusukela emzamweni wokuqala wokufaka.

Usonkontileka wokwakha eRomania othola izinduku zomhlabathi ezifakwe ugesi zesakhiwo sehhovisi lezentengiselwano eBucharest ubhekane nemijikelezo yenhlabathi encibilikiswa yiqhwa engaguqula ukuhambisana kwezinduku futhi yandise ukumelana nomhlabathi ebusika obulandelanayo. Usonkontileka ucacise ukubekezelelana kokuqina okungu-1 mm ngemitha, imiphumela yokuhlolwa kokumelana nomhlabathi edingekayo yesisekelo sendawo sobumba, futhi wabeka inani le-oda ezingcezu ezingu-500 ukuze lihambisane nomklamo wegridi yomhlabathi wesakhiwo. Ngokudlulisela izidingo ze-MOQ kanye nesikhathi sokuhola ekuqaleni kwe-RFQ, usonkontileka uthole indawo yokukhiqiza ehambisana nesheduli yokwakha futhi wagwema amanani aphezulu ahambisana nama-oda asheshayo ngesikhathi sokwakha okuphezulu.
