Kwabakhi beoyile negesi, izixhobo zokuwelda zokukhusela i-cathodic zezona zinto zisetyenziswayo ezincamathisela iileyiti zovavanyo, iintambo ze-anode kunye nee-bonding conductors kumbhobho ongcwatyiweyo - kwaye isigqibo sokuthenga siphantsi kwezinto ezintathu: umgubo wokuwelda we-thermit ohambelana nezinto zakho zomqhubi kunye nobukhulu, i-graphite mold esindayo iijoyinti ezingama-80-100, kunye nomthengisi opakisho lwakhe kunye namaphepha akhe asindayo ekuhlolweni kokuthumela ngaphandle. Ndisebenza ngaphakathi kumzi-mveliso owenza ezi zinto, kwaye kwesi sikhokelo ndihamba malunga noko sikuxubayo, oko kugugayo, ukuba zeziphi imigangatho eza kukhankanywa liqela lakho le-QC (I-AMPP/NACE SP0169, I-ISO 15589-2:2024, IEEE 837), kunye nezibalo ezisetyenziswayo ekufuneka uzisebenzise ngaphambi kokuba ukhuphe umyalelo wokuthenga.
IZINTO EZIBALULEKILEYO EZITHATHWAYO
- Umgubo wokuwelda we-thermit womsebenzi wepayipi ngumxube we-copper oxide kunye ne-aluminium, kwaye kufuneka uxutywe nezinto zomqhubi wakho kunye nobukhulu - umxube oqhelekileyo uvelisa amalungu abuthathaka, axhathisayo kakhulu.
- I-graphite mold esemgangathweni inika amalungu e-weld angama-80–100 ngaphambi kokuba itshintshelwe kwenye, ngoko ke inani le-mold — hayi inani le-powder — lidla ngokuqhuba ishedyuli yakho yoku-odola kwakhona.
- Ukupakisha okusemgangathweni wokuthumela ngaphandle yiziqwenga ezili-10 kwibhokisi nganye kunye neebhokisi ezili-10 kwibhokisi nganye, ezithunyelwa ngaphandle kweNingbo okanye eShanghai, ezinomthamo wokubonelela ngefektri weziqwenga ezili-100,000 ngenyanga.
- Izalathiso zomsebenzi wepayipi olawulwa yi-US 49 CFR Icandelo 195 lokukhusela i-cathodic; umgangatho woqhagamshelo uhlala ufanelekile ngokuchasene ne-IEEE 837.
- Akukho mthombo wamandla wangaphandle ofunekayo kwi-pipeline thermit welding, yiyo loo nto ihlala iyindlela eqhelekileyo kwiimeko ezikude.
Ukusuka kwi-Arc Strikes ukuya kwi-Molecular Bonds: Kutheni ii-CP Crews zisacacisa i-Pipeline Thermit Welding?
Impendulo emfutshane: kuba inkqubo yokukhusela i-cathodic (CP) — ukusetyenziswa ngobunjineli kwe-direct current okanye ii-anode ze-sacrificial ukubamba umbhobho wentsimbi ongcwatyelweyo kwindawo apho ukugqwala kuba yinto engabalulekanga — inokuthenjwa kuphela njengokunxibelelana kwayo.Ngenxa yokuba yonke intambo yovavanyo, intambo ye-anode kunye nentambo yebhondi kufuneka zihlale zisebenza ngombane ubomi boyilo lombhobho, abakhi bachaza ibhondi yemolekyuli endaweni yeyomatshini.Ukuwelda kwe-exothermic, okwabhalwa njengokwelda kwe-thermit kwaye okwaziwa kweli candelo ligama elivela kurhwebo elithi CAD weld (elivela kuphawu lweCadweld), kudibanisa umqhubi kumphezulu wombhobho kwi-graphite mold kusetyenziswa ubhedu olunyibilikisiweyo oluveliswa yi-powder reaction. Akukho clamp yokuyikhulula, akukho joint eqhotsiweyo yokutyibilika, kwaye akukho arc strike eludongeni lombhobho.
Ndiyibukele le nto isenzeka kwicala lokubonelela kangangeminyaka elishumi elinesibini. Xa umntu osebenza ngemibhobho etshintsha ukusuka kwiikliphu zoomatshini ukuya kwiintambo zombane ezisetyenziswa exothermic, iodolo yokuqala yokuthenga idla ngokuba ncinci kwaye ilumke — iqela elinye, elinye lisasazeke. Iodolo yesibini inkulu.Ngenxa yokuba i-weld ayifuni generator, akukho matshini wokuwelda kwaye akukho welder onelayisenisi emseleni, amaqela agcina amazinga emveliso nokuba kwiindawo ezikude apho ukuthutha izixhobo zokuwelda ze-arc kungenzeki khona.Amaxwebhu emveliso yefektri yethu ayibeka ngokucacileyo le nto: le ndlela ingabizi kakhulu, iyaphatheka, kwaye kulula ukuyisebenzisa ngaphandle kwesakhono esikhethekileyo. Oko akulolwimi lokuthengisa; yingakho le ndlela itshintshe uqhagamshelo lwemishini kwi-grounding kunye ne-CP zisebenza kwiminyaka engamashumi amabini edlulileyo.
Izinto zokuWelda zoKhuseleko lweCathodic: Yintoni kanye kanye engaphakathi kwiBOM yoMthengisi?
Ibhili epheleleyo yezinto zokunxibelelana kwe-CP exothermic inezinto ezininzi kunokuba abathengi abaninzi abaqalayo belindele. Kwimveliso yethu, ndingabukela iseti elungele ukuthunyelwa idibana:umgubo wokuwelda we-thermitngokwayo, i-graphite mold eyenza i-joint, i-flint ignition gun, i-metal disc evala igumbi le-powder de kuqale ukusabela, i-fastening clamp, iiglavu ezingatshisi ubushushu, kunye neebhrashi zokucoca. Phosa enye yezi kwaye iqela lakho liza kwenza i-provisation emseleni.
Izinto ezintathu zifanele ingqalelo yomthengi kuba zimisela umgangatho we-joint:
- Umgubo wokuwelda we-thermit.Umgubo wethu wokuwelda we-exothermic ngumxube we-copper oxide kunye ne-aluminium — i-reaction yehlisa i-copper oxide kwi-copper enyibilikisiweyo kumaqondo obushushu aphezulu ngokwaneleyo ukuba adibanise ii-copper conductors kwi-steel pipe. Ingongoma ebalulekileyo yokufumana umlinganiselo: sixuba umgubo ukuze ulingane nezinto zomqhubi wakho kunye necandelo elinqamlezileyo,Kuba itshaja encinci ishiya ijoyinti engaphelelanga ngelixa enkulu kakhulu ikhupha isinyithi kwisikhunta kwaye ichitha izinto kuyo yonke ikhonkco..
- Ukujikeleza kwe-thermit weldingkunye nezinto zokuqala.I-flux igcina i-reaction icocekile kwaye inceda ubhedu olunyibilikisiweyo lumanzise umphezulu wombhobho; ngeentsasa ezimanzi okanye ngentsimbi engacocwanga kakuhle, i-flux yiyo egcina i-joint kwi-porosity.
- I-graphite mold.Le yinxalenye yokuchaneka. I-graphite mold eyenziwe kakuhle ivala ngokuqinileyo umqhubi nombhobho, kwaye iirekhodi zethu zefektri zibonisa ubomi benkonzo be-80-100 joints nge-mold nganye — ixesha elide kunezinye ii-molds ezininzi ezikhuphisanayo abathengi bethu abaye bazithelekisa nazo. I-mold egugileyo ivuza ubhedu olunyibilikisiweyo, kwaye i-mold evuzayo ivelisa i-joint ongayikwamkeli umhloli wakho.
Ukuwelda kweThermit yePipeline emseleni: Le nkqubo iqhubeka njani phantsi kwexesha elibekiweyo lokugquma?
Kwi-live spread, umqobo awufane ube yi-weld ngokwayo — liqela le-coating elingasemva kwakho. Uqhagamshelo lwe-exothermic luthatha imizuzu embalwa: coca umphezulu wombhobho kunye ne-conductor kwisinyithi esikhanyayo, ubeke i-mold, ulahle idiski yesinyithi, utshaje umgubo, uvuthe nge-flint gun, ulinde impendulo, uqhawule i-mold, kwaye ucoce i-joint ye-coating applicator. Sifote ulandelelwano lwethu lwentsimi olunezinyathelo ezisibhozo kwi-joints zokwenyani, kwaye luqala ukusuka ekulungiseleleni umphezulu ukuya kuqhagamshelo olugqityiweyo, olulungele ukuhlolwa.
Ngokwendlela endibona ngayo kwii-odolo eziphindaphindwayo, inkqubo ibambelela ngokwenene ekuphindaphindweni. Nje ukuba iqela lenze iijoyinti ezilishumi elinambini, iindlela zokungaphumeleli zihlala ziyinkqubo, kungekhona izinto eziphathekayo: ukufuma kwi-mold, ioyile okanye igrisi kumbhobho, okanye i-mold ephinde yasetyenziswa ngaphambili.Ngenxa yokuba isinyithi esishushu esinyibilikisiweyo esitshizwe ngamanzi okanye ungcoliseko lwegrisi sibangela ukutsha kunye namalungu angafunwayo, amaxwebhu ethu okupakisha agxininisa ekugcinweni okomileyo kunye neendawo ezicocekileyo nezomileyo - kwaye ndiphinda eso silumkiso kuyo yonke i-invoyisi yeproforma endiyithumelayo.Ukuba iqela lakho lisebenza kwimiphunga evuthayo okanye eluthulini, yeka; loo nto yimeko yomlilo nokuqhuma, hayi imeko esemgangathweni.
Uhlolo lweeNkcukacha Ngaphambi kokuba Ufumane Umthombo: Yeyiphi iMigangatho eLawula uQhagamshelo lwe-Exothermic kwiMibhobho?
Ifayile yakho ye-QC, hayi ikhathalogu yomthengisi, yiyo egqibayo ukuba kuthetha ukuthini “ukwamkeleka”. Kwiiphakheji zokuthenga endizihlolayo, kuvela iireferensi ezine ngokuphindaphindiweyo:
- I-AMPP / NACE SP0169, Ulawulo Lokugqwala Kwangaphandle Kwiinkqubo Zemibhobho Engaphantsi Komhlaba okanye Engaphantsi Komhlaba, ngumgangatho oza kucatshulwa yinjineli yakho yokugqwala kwiikhrayitheriya zenkqubo ye-CP kunye nendlela yokufakela imibhobho engaphantsi komhlaba.
- I-ISO 15589-2:2024, uhlelo lwesithathu lwangoku lokukhusela i-cathodic yemibhobho engaselunxwemeni, lulawula uyilo, izixhobo, ukufakelwa, ukuqaliswa kunye nokugcinwa kweenkqubo ze-CP zemibhobho engaphantsi komhlaba kunye nee-risers.
- IEEE 837, Umgangatho woQhagamshelo oluQhelekileyo oluQhelekileyo olusetyenziswa kwi-Substation Grounding, luyilo lomgangatho olusetyenziswa kakhulu xa umthengi efuna ubungqina bokuba uhlobo loqhagamshelo oluvela kwi-exothermic luhlala luphantsi kwesiphako kunye noxinzelelo lokusingqongileyo - nokuba kukwimisebenzi yepayipi, ingqiqo yalo yovavanyo (ukujikeleza ngoku, ukuqandisa, ulandelelwano lokugqwala) yiyo leyo abahloli bereferensi bayiqondayo.
- Kwimibhobho yamanzi elawulwa yi-US,49 CFR Icandelo 195(PHMSA) yenza ulawulo lwangaphandle lokugqwala — kuquka nokukhuselwa kwe-cathodic — lube ngumthwalo olawulayo, yiyo loo nto amaxwebhu oqhagamshelo ephelela kwiifayile zophicotho-zincwadi.
Umda omnye onyanisekileyo: umthengisi we-powder kunye ne-mold angabhala phantsi ukwakheka kwezinto, uvavanyo lomntu wesithathu (iimveliso zethu zivavanywa yi-CEPRI, i-China Electric Power Research Institute) kunye nokupakisha - kodwa isiqinisekiso senqanaba elidibeneyo siyenzeka kwicala lakho, kubaqhubi bakho kunye nabahloli bakho. Ndixelela wonke umthengi omtsha wekontrakta into efanayo: oda ubungakanani bovavanyo kuqala, weld iijoyinti zakho zovavanyo, kwaye uvumele umhloli wakho avule ezimbalwa. Nawuphi na umzi-mveliso othintela loo nyathelo ukuxelela into ethile.
Izibalo Zokuthengwa Akukho mntu Uprintayo: Ubomi Bokubumba Nokusetyenziswa Komgubo Zizibangela Njani Iindleko Zokwenene?
Kulapho idatha yethu yefektri itshintsha khona isigqibo sokuthenga. Umgubo uphuma intlawulo enye kwijoyinti nganye, kodwa kwiirekhodi zethu zokuthumela iimolds zisetyenziswa kwigophe - kwaye loo gophe kulapho uhlahlo lwabiwo-mali luvuza khona. Ubomi bethu benkonzo erekhodiweyo kwi-mold yegrafiti esemgangathweni ziijoyinti ezingama-80–100; abakhi beemolds bandibonisa kubathengisi bangaphambili bedla ngokuqhekeka okanye ukuvuza ngaphambili.Ngenxa yokuba i-mid-joint engasebenziyo ichitha i-powder charge, i-disc, ixesha labasebenzi kwaye ngamanye amaxesha i-conductor iphela, i-mold engabizi kakhulu idla ngokuba yeyona ibiza kakhulu - ixabiso lilonke nge-joint egqityiweyo liyehla njengoko ubomi be-mold bunyuka, nokuba ixabiso leyunithi nge-mold liphezulu.Andizukushicilela amanani eedola apha, kuba amagama okuthutha impahla, ubungakanani beodolo kunye nesithuba sakho sokukhupha impahla zishukumisa amanani okwenyani kakhulu kunexabiso elinye elithembekileyo; into endinokuyishicilela kukwakheka kwezibalo.

Ukuhlola umthengisi wezinto zeThermit: Imibuzo emithandathu eyahlula iifektri kubathengisi
Uninzi lwentlungu endiyibonayo kolu rhwebo luvela ekuthengeni ngabathengisi abangakwaziyo ukuphendula imibuzo yobugcisa. Nokuba uthenga kuthi okanye akunjalo, le mibuzo mithandathu ityhila ukuba ngubani ngokwenene owenze imveliso:
- Ungandibonisa indlela yokuxuba ipowder ehambelana nezinto zam zomqhubi kunye nobukhulu, kwaye uchaze umlinganiselo wokuxuba oza kuwusebenzisa kuyo?
- Ingakanani ixesha lakho elibhaliweyo lenkonzo yokubumba i-graphite kwi-weld joints, kwaye loo manani ithatha ukuba zeziphi iimeko zokuphatha okanye zokugcina?
- Ngowuphi umbutho ozimeleyo oye wavavanya izixhobo zakho zokuwelda — kuthi impendulo yi-CEPRI — kwaye ungabelana ngesalathiso sovavanyo?
- Upakisha njani umgubo kunye neenkuni zokuthutha ngolwandle — eyethu yiziqwenga ezili-10 kwibhokisi nganye kunye neebhokisi ezili-10 kwibhokisi nganye — kwaye uthumela ukusuka kweliphi izibuko?
- Ngowuphi umthamo wenyanga onokuzibophelela kuwo ngokubhaliweyo — umgca wethu usebenza kwiinxalenye ezili-100,000 ngenyanga — kwaye lingakanani ixesha lakho lokubonelela ngeenkonzo ngexesha lonyaka elixakekileyo?
- Ngaba uthumela izixhobo ezipheleleyo (i-flint gun, ii-clamps, iiglavu, iibrashi) kunye namanqaku okhuseleko abhaliweyo kunye nomyalelo wokuqala, okanye ezo zinto zingaphezulu komgca?
Ngokwamava am, umzi-mveliso uphendula ezi mpendulo nge-imeyile enye, ngelixa umthengisi ezithumela aze abuye emva kweentsuku ezintathu ephethe uqikelelo.Ngenxa yokuba izinto zokuwelda zokukhusela i-cathodic zisetyenziswa kufutshane nokhuseleko kwiziseko ezilawulwayo, ixabiso lempendulo engalunganga ayilombuyekezo - kukusasazwa okwaliweyo kunye neqela elibuyiselweyo.
Amaxwebhu, ukupakisha, kunye nexesha lokukhokela: Apho ii-odolo zokungenisa impahla zihlala zingahambi kakuhle khona?
Emva kweminyaka elishumi elinesibini yokuthumela iimveliso ezisemgangathweni kunye nezobushushu ngaphandle, ndingakuxelela ukuba ukusilela esikubonayo kuyadinisa - kwaye ndicinga ukuba ezo ziindaba ezimnandi, kuba ukusilela okudinisayo kunokuthintelwa. Siyazi ukuba umgubo ufunxa umswakama, ngoko ke sivala yonke ibhotile ngaphambi kokuba iphume emgceni wethu kwaye iibhokisi kufuneka zisinde kuhambo olufumileyo lwesikhongozeli; iimbumba zibuthathaka, ngoko ke zifuna ukwahlulwa kunye nokuthotywa ngaphakathi kwebhokisi; kwaye siqinisekisa ukuba amaphepha ethu abiza iimpahla ngendlela umthengisi wakho werhafu kunye nesebe le-QC lomthengi wakho abayiqondayo. Sithumela i-ex Ningbo okanye iShanghai, kwaye kubangenisi bokuqala ndihambisa amaxwebhu kunye nomthengisi ngaphambi kokuba inqanawa ihambe, hayi emva kokuba ifikile.
Icebiso lam lokugqibela kukulandelelana: qala ngoku-oda i-pilot, weld uze wahlule iindawo zakho zokuvavanya, uze ulinganise ubungakanani beprojekthi ngenqaku loku-odola kwakhona elibalwe ukusuka kubomi bokubumba endaweni yokuqikelela. Ukuba ufuna iseti yesibini yamehlo kwi-RFQ yakho ngaphambi kokuba uyithumele nakubani na - kuquka nathi - yithumele. Ndingathanda ukulungisa inkcazo kunokuthumela ngokuchasene nembi.
