Kwabakhi be-oyela negesi, izinto zokushisela zokuvikela i-cathodic ziyizinto ezisetshenziswayo ezinamathisela ama-test lead, izintambo ze-anode kanye nama-bonding conductors epayipini elifihliwe — futhi isinqumo sokuthenga sincike ezintweni ezintathu: i-thermit welding powder ehambisana nezinto zakho zomshiseli kanye nosayizi, isikhunta se-graphite esisinda emajoyintini angu-80-100, kanye nomhlinzeki opakisha kanye namaphepha akhe asinda ekuhlolweni kokuthumela kwamanye amazwe. Ngisebenza ngaphakathi efektri eyenza lezi zinto, futhi kulo mhlahlandlela ngidlula kulokho esikuxubayo, okugugayo, ukuthi ithimba lakho le-QC lizokhuluma ngaziphi izindinganiso (I-AMPP/NACE SP0169, I-ISO 15589-2:2024, I-IEEE 837), kanye nezibalo ezisebenzisekayo okufanele uzisebenzise ngaphambi kokukhipha i-oda lokuthenga.

Kusukela Ekushayweni Kwe-Arc Kuya Kuzibopho Zama-Molecular: Kungani Abasebenzi Be-CP Besacacisa Ukushiswa Kwe-Pipeline Thermit?

Impendulo emfushane: ngoba uhlelo lokuvikela i-cathodic (CP) — ukusetshenziswa okuthuthukisiwe kwamanje aqondile noma ama-anode okuzidela ukuze kubanjwe ipayipi lensimbi eligqitshwe endaweni enamandla lapho ukugqwala kuba yinto encane — kuthembekile kuphela njengokuxhumeka kwalo.Ngenxa yokuthi yonke intambo yokuhlola, ikhebula le-anode kanye nentambo yebhondi kumele ihlale iqhubeka ngogesi impilo yomklamo wephayiphi, osonkontileka bachaza ibhondi yama-molecule esikhundleni seyomshini.Ukushisela kwe-exothermic, okubhalwe futhi ngokuthi ukushisela kwe-thermit futhi okwaziwa emkhakheni ngegama elisuselwa ekuhwebeni elithi CAD weld (elivela kumkhiqizo we-Cadweld), kuhlanganisa umqhubi nobuso bepayipi ku-graphite mold kusetshenziswa ithusi elincibilikisiwe elikhiqizwa yi-powder reaction. Akukho clamp yokuyikhulula, akukho brazed joint yokushelela, futhi akukho arc strike odongeni lwepayipi.

Ngikubukele lokhu kusukela ohlangothini lokunikezwayo iminyaka eyishumi nambili. Lapho umakhi wepayipi eshintsha kusuka kuma-clamp omshini kuya ekuxhumeni kwe-exothermic, i-oda lokuqala lokuthenga livame ukuba lincane futhi liqaphile — iqembu elilodwa, elinye lisakazeke. I-oda lesibili liba likhulu.Ngenxa yokuthi i-weld ayidingi i-generator, ayikho imishini yokushisela futhi ayikho i-welder enelayisensi emseleni, amaqembu agcina amazinga okukhiqiza ngisho nasezindaweni ezikude lapho ukuthutha imishini yokushisela i-arc kungenzeki khona.Imibhalo yomkhiqizo yefektri yethu ikubeka ngokusobala: le ndlela ishibhile, iyaphatheka, futhi kulula ukuyisebenzisa ngaphandle kwekhono elikhethekile. Lokho akulona ulimi lokumaketha; yingakho le ndlela ishintshe ukuxhumana kwemishini phakathi kwe-grounding kanye ne-CP eminyakeni engamashumi amabili edlule.

Izinto Zokushisela Zokuvikela I-Cathodic: Yini Engaphakathi Kwe-BOM Yomkontileka Empeleni?

Iqoqo eliphelele lezinto zokuxhumanisa i-CP exothermic linezinto eziningi kakhulu kunalokho abathengi abaningi bokuqala abakulindele. Esitezi sethu sokukhiqiza, ngingabuka isethi elungele ukuthunyelwa ihlangana: iimpuphu yokushisela ye-thermituqobo, isikhunta se-graphite esakha i-joint, isibhamu se-flint ignition, idiski yensimbi evala igumbi le-powder kuze kube yilapho ukusabela kuqala, i-fastening clamp, amagilavu ​​​​angashisi, kanye namabhulashi okuhlanza. Uphuthelwe yinye yalezi futhi iqembu lakho lizozenzela izinto emseleni.

Izingxenye ezintathu zifanelwe ukunakwa ngumthengi ngoba zinquma ikhwalithi yokuhlanganiswa:

• Impuphu yokushisela i-thermit.Impuphu yethu yokushisela ye-exothermic iyingxube ye-copper oxide ne-aluminium — ukusabela kunciphisa i-copper oxide ibe yithusi elincibilikisiwe emazingeni okushisa aphezulu ngokwanele ukuhlanganisa abaqhubi bethusi nepayipi lensimbi. Iphuzu elibalulekile lokuthola isilinganiso: sixuba i-powder ukuze ifane nezinto zomqhubi wakho kanye nesigaba esiphambene,Ngoba ishaja encane ishiya ijoyinti elingaphelele kuyilapho elikhulu kakhulu likhipha insimbi esikhumbeni futhi lichithe izinto kuyo yonke intambo yokuxhuma..
• Ukushintshashintsha kokushisela kwe-thermitkanye nezinto zokuqala.Ukugeleza kugcina ukusabela kuhlanzekile futhi kusiza ithusi elincibilikisiwe ukuthi limanzise ubuso bepayipi; ekuseni okumanzi noma ngensimbi engahlanzwanga kahle, ukugeleza yikho okusindisa ilunga ekubhobozeni.
• Isikhunta se-graphite.Lesi yingxenye yokucacisa. Isikhunta se-graphite esifakwe kahle sivala ngokuqinile eduze komqhubi kanye nepayipi, futhi amarekhodi ethu efektri abonisa impilo yesevisi yamalunga angu-80-100 ngesikhunta ngasinye — isikhathi eside kunesikhunta esiningi esincintisana naso amakhasimende ethu asiqhathanise naso. Isikhunta esigugile sivuza ithusi elincibilikisiwe, futhi isikhunta esivuzayo sikhiqiza iqhubu elizolahlwa ngumhloli wakho.

Impuphu yokuwelda ye-thermit ye-SHIBANG: ingxube ye-oxide yethusi ne-aluminium, ebhodleleni ukuze isetshenziswe ensimini ezixhumweni zokuvikela i-cathodic zamapayipi.

Ukushisela i-Pipeline Thermit emgodini: Inqubo Ihlala Kanjani Ngaphansi Kwezinsuku Zokugcina Zokumboza?

Uma kusakazwa bukhoma, umkhawulo awuvamile ukuba yi-weld ngokwayo — yiqembu elihlanganisayo elingemuva kwakho. Ukuxhumeka kwe-exothermic kuthatha imizuzu embalwa: hlanza ubuso bepayipi kanye nomqhubi wensimbi ekhanyayo, beka isikhunta, uphonsa idiski yensimbi, ushaje impuphu, uvuthe ngesibhamu se-flint, ulinde ukusabela, uphule isikhunta, bese uhlanza i-joint ye-applicator yokufaka isikhunta. Sithathe izithombe zochungechunge lwethu lwensimu olunezinyathelo eziyisishiyagalombili kuma-joints angempela, futhi luqala kusukela ekulungiseleleni ubuso kuze kube sekuhlanganisweni okuqediwe, okulungele ukuhlolwa.

Ukulandelana kwensimu kanye nemidwebo yamalunga okuxhumanisa i-CAD weld: ukulungiswa kwendawo, izihlalo zesikhunta, ukuthungela, kanye namalunga aqediwe alungele ukumbozwa.

Kusukela kulokho engikubonayo kuma-oda okuphindaphinda, inqubo ibambelela ngempela ekuphindaphindweni. Uma iqembu selihlanganise amalunga ayishumi nambili, izindlela zokwehluleka cishe njalo ziyinqubo, hhayi izinto ezibonakalayo: umswakama esikhumbeni, uwoyela noma amafutha epayipini, noma isikhunta esisetshenziswe kabusha esikhathini esidlule.Ngenxa yokuthi insimbi eshisiwe eshisayo efafazwe ngamanzi noma ukungcola kwamafutha ibangela kokubili ukusha kanye namalunga alahliwe, amadokhumenti ethu okupakisha agcizelela ukugcina izinto eyomile kanye nezindawo ezihlanzekile nezomile — futhi ngiphinda leso sixwayiso kuyo yonke i-invoyisi yephroforma engiyithumelayo.Uma iqembu lakho lisebenza emisipheni evuthayo noma othulini, yeka; lokho kuyisimo somlilo nokuqhuma, hhayi isimo sekhwalithi.

Ukuhlolwa Okucacile Ngaphambi Kokuthi Uthole Umthombo: Yimaphi Amazinga Alawula Ukuxhumeka Kwe-Exothermic Kumapayipi?

Ifayela lakho le-QC, hhayi ikhathalogi yomhlinzeki, linquma ukuthi kusho ukuthini ukuthi “okwamukelekayo”. Kumaphakheji okuthenga engiwabuyekezayo, kuvela izinkomba ezine ngokuphindaphindiwe:

• I-AMPP / NACE SP0169, Ukulawulwa Kokugqwala Kwangaphandle Ezinhlelweni Zokuphamba Zensimbi Ezingaphansi Komhlaba noma Ezicwiliswe Ngaphansi Komhlaba, kuyindinganiso eyisisekelo unjiniyela wakho wokugqwala azoyisho ngezinqubo zesistimu ye-CP kanye nomkhuba wokufaka kumaphayiphi agqitshiwe.
• I-ISO 15589-2:2024, uhlelo lwesithathu lwamanje lokuvikelwa kwe-cathodic yamapayipi asogwini, lulawula ukuklama, izinto zokwakha, ukufakwa, ukuqalwa kanye nokugcinwa kwezinhlelo ze-CP zamapayipi angaphansi komhlaba kanye nezikhuphuli.
• I-IEEE 837, Izinga Lokuxhumeka Okuhlala Njalo Okufanelekayo Okusetshenziswa Esiteshini Esingaphansi, luhlaka lweziqu oluvame ukusetshenziswa lapho umthengi efuna ubufakazi bokuthi uhlobo lokuxhumeka olungaphandle luhlala njalo ngaphansi kwephutha kanye nokucindezeleka kwemvelo - ngisho nasemisebenzini yamapayipi, i-logic yalo yokuhlola (ukujikeleza kwamanje, ukuqandisa-ukuncibilika, ukulandelana kokugqwala) yilokho abahloli bezinkomba abakuqaphelayo.
• Kumapayipi amanzi alawulwa yi-US,Ingxenye 49 ye-CFR 195(PHMSA) yenza ukulawulwa kokugqwala kwangaphandle — okuhlanganisa nokuvikelwa kwe-cathodic — kube yisibopho sokulawula, yingakho imibhalo yokuxhumeka igcina isemafayeleni okuhlola.

Umkhawulo owodwa oqotho: umhlinzeki we-powder kanye ne-mold angabhala phansi ukwakheka kwezinto, ukuhlolwa komuntu wesithathu (imikhiqizo yethu ihlolwa yi-CEPRI, i-China Electric Power Research Institute) kanye nokupakisha — kodwa ukufaneleka kwezinga elihlangene kwenzeka kuwe, kubaqhubi bakho kanye nabahloli bakho. Ngitshela wonke amakhasimende amasha enkontileka into efanayo: qala ngoku-oda inani lokuhlola, ushisele amajoyinti akho okuhlola, bese uvumela umhloli wakho ukuthi avule ambalwa. Noma iyiphi imboni evimbela leso sinyathelo ikutshela okuthile.

Izibalo Zokuthengwa Kwempahla Akukho Okunyatheliswayo: Ukuphila Kwesikhunta Nokusetshenziswa Kwempuphu Kuzibiza Kanjani Izindleko Zangempela?

Yilapho idatha yethu yasefektri ishintsha khona isinqumo sokuthenga. Impuphu ikhishwa kanye ngejoyinti ngayinye, kodwa kumarekhodi ethu okuthumela izikhunta zisetshenziswa egodini — futhi lelo godini yilapho isabelomali sivuza khona. Isikhathi sethu senkonzo esirekhodiwe se-graphite mold esezingeni eliphezulu singamajoyinti angu-80–100; izikhunta ezingochwepheshe zingibonisa kubahlinzeki bangaphambilini zivame ukuqhekeka noma ukuvuza kudala kakhulu.Ngenxa yokuthi i-mid-joint engasebenzi kahle ichitha i-powder charge, i-disc, isikhathi sabasebenzi futhi ngezinye izikhathi ukuphela komqhubi, i-mold eshibhile ivame ukuba yindleko ebiza kakhulu - izindleko eziphelele nge-joint eqediwe ziyehla njengoba impilo ye-mold ikhuphuka, ngisho nalapho intengo yeyunithi nge-mold iphakeme.Ngeke ngiphrinte izibalo zamadola lapha, ngoba imigomo yokuthutha impahla, ivolumu ye-oda kanye ne-port of discharge yakho kuhambisa izinombolo zangempela kakhulu kunoma yiliphi intengo eyodwa ethembekile; engingakuphrinta isakhiwo sezibalo.

Sebenzisa izinombolo zakho ngesilinganiso esingezansi — sisebenzisa izibalo zethu eziqoshwe efektri (amalunga angu-80-100 ngesikhunta ngasinye; ukupakisha kwamanye amazwe kwezingcezu eziyi-10 ngebhokisi ngalinye namabhokisi ayi-10 ngebhokisi ngalinye) kanye nenani lakho lamalunga. Akukho mali ehilelekile; iphuzu liwukuba ulinganise i-oda, kanye nephuzu lokuhlela kabusha, ngamayunithi angokoqobo kuqala.

Ukuhlola Umhlinzeki Wezinto Ezisetshenziswa Ku-Thermit: Imibuzo Eyisithupha Ehlukanisa Amafektri Nabathengisi

Ubuhlungu obukhulu engibubonayo kulo mkhakha buvela ekuthengeni ngokusebenzisa abathengisi abaningi abangakwazi ukuphendula imibuzo yobuchwepheshe. Kungakhathaliseki ukuthi uthenga kithi noma cha, le mibuzo eyisithupha iveza ukuthi ubani ngempela owenza umkhiqizo:

1. Ungangibonisa yini ifomula yempuphu ehambisana nezinto zami zomqhubi kanye nosayizi, bese uchaza isilinganiso sokuxuba ongasisebenzisa kuyo?
2. Ingakanani impilo yakho yenkonzo yesikhunta se-graphite ebhalwe phansi emajoyintini okushisela, futhi yiziphi izimo zokuphatha noma zokugcina leso sibalo esizicabangayo?
3. Yimuphi umbutho ozimele ohlole izinto zakho zokushisela — kithi impendulo yi-CEPRI — futhi ungabelana ngereferensi yokuhlola?
4. Upakisha kanjani ufulawa kanye nezikhunta zokuthutha ngolwandle — eyethu izingcezu eziyi-10 ngebhokisi kanye namabhokisi ayi-10 ngebhokisi — futhi uthumela kusuka kuliphi itheku?
5. Yimuphi umthamo wokuphakelwa wanyanga zonke ongazibophezela kuwo ngokubhala phansi — umugqa wethu usebenza ngezingcezu eziyi-100,000 ngenyanga — futhi yisiphi isikhathi sakho sokuhola esithembekile ngesizini ematasa?
6. Ingabe uthumela isethi ephelele yamathuluzi (isibhamu se-flint, ama-clamp, amagilavu, amabhulashi) kanye namanothi okuphepha abhaliwe nge-oda lokuqala, noma ingabe lezo zinto ezengeziwe?

Ngokwami, ifektri iphendula lokhu nge-imeyili eyodwa, kuyilapho umthengisi ekudlulisela phambili bese ebuya ezinsukwini ezintathu kamuva eqagela.Ngenxa yokuthi izinto zokushisela zokuvikela i-cathodic zisetshenziswa eduze nokuphepha engqalasizinda elawulwayo, izindleko zempendulo engalungile azikho ukubuyiselwa kwemali - kuyi-spread enqatshiwe kanye neqembu elibuyiselwe emsebenzini.

Amadokhumenti, Ukupakisha, kanye Nesikhathi Sokuhola: Kukuphi lapho Ama-oda Okungenisa Avame Ukungahambi Kahle?

Ngemva kweminyaka eyishumi nambili yokuthumela imikhiqizo yokumisa umhlabathi kanye nemikhiqizo engaphandle, ngingakutshela ukuthi ukwehluleka esikubonayo kuyacasula - futhi ngibona lokho njengezindaba ezinhle, ngoba ukwehluleka okuyisicefe kungavinjelwa. Siyazi ukuthi impuphu imunca umswakama, ngakho-ke sivala wonke amabhodlela ngaphambi kokuba asuke emgqeni wethu futhi amabhokisi kumele asinde ohambweni lwesitsha esinomswakama; isikhunta siyaphuka, ngakho-ke sidinga ukuhlukaniswa kanye nokusikwa ngaphakathi kwebhokisi; futhi siyaqinisekisa ukuthi amaphepha ethu aqamba izimpahla ngendlela umthengisi wakho wamasiko kanye nomnyango we-QC weklayenti lakho abayibonayo. Sithumela i-ex Ningbo noma i-Shanghai, futhi kwabangenisi bokuqala ngihambisa amadokhumenti nomthengisi ngaphambi kokuba umkhumbi uhambe, hhayi ngemva kokuba ufikile.

Isikhunta sokushisela se-SHIBANG graphite exothermic esine-handle clamp kanye nesibhamu sokushaqeka se-flint — isikhathi sesevisi singu-80–100 amalunga ngesikhunta ngasinye.

Iseluleko sami sokugcina ukulandelana: qala ngoku-oda i-pilot, weld bese uhlukanisa amajoyinti akho okuhlola, bese ukala ukuze ubonise inani ngephuzu loku-oda kabusha elibalwe kusukela empilweni yesikhunta kunokuthi uqagele. Uma ufuna isethi yesibili yamehlo ku-RFQ yakho ngaphambi kokuthi uyithumele kunoma ubani - okuhlanganisa nathi - yithumele. Ngingathanda ukulungisa imininingwane kunokuthumela ngokumelene nembi.
