    • UPiral Sullyged ARCH WELDING ekwakhiweni komugqa wepayipi wamafutha: Ukuqinisekisa impilo yenkonzo kanye nokwethenjwa

    Incazelo emfushane:

    Ukwakhiwa kweimigqa yamapayipi kawoyela inqubo ebalulekile futhi eyinkimbinkimbi edinga amazinga aphezulu kakhulu wobuchwepheshe be-welding. Phakathi kwezindlela ezahlukahlukene ze-welding eziqashiwe ezisetshenzisiwe, i-arlding ye-arlding ephakathi nendawo engaphakathi (i-HSAW) ivelele njengokukhetha kokuqala ngenxa yokusebenza kwayo okuphezulu nempumelelo ekuqinisekiseni impilo yenkonzo kanye nokwethenjwa kwamapayipi kawoyela. Kule bhulogi, sizokwelulela ukubaluleka kwe-Hsaw e-Amaphayi Pipelines Welding futhi sihlole izinzuzo zayo kanye nenani elikhulu ekufezekiseni umhlaba'Izidingo zokuhamba kawoyela ezikhulayo.

    Funda nge-HSAW:

    Kuvunguza i-arc egxilile ye-arckungubuchwepheshe obuthuthukisiwe we-welding obuhlanganisa imigomo yokufaka i-arc welding ye-arc efakwe kanye ne-spine shop. Kubandakanya ukusebenzisa inqubo ye-welding ezenzakalelayo yokwakha i-Weld eqhubekayo eqhubekayo ngokudla ucingo oluqinile lwe-flux embozwe i-arc. Le ndlela iqinisekisa ama-welds angaguquki futhi asezingeni eliphakeme, isusa ubungozi bokulimala okuvamile nezinye izindlela ze-welding.

    Ukubaluleka kwe-Hsaw ekwakhiweni kwamapayipi kawoyela:

    1 I-Weld eqhubekayo eqhubekayo eyenziwe yilobu buchwepheshe ithuthukisa ubuqotho besakhiwo futhi ibalulekile ukubekezelela izingcindezi eziphakeme, amazinga okushisa aphezulu kanye nezinto zezemveloipayipi kawoyela iqoloubuso ngesikhathi sokuphila kwabo kwenkonzo.

    2. Impilo ende nokuthembela okuqinile: Imigqa yamapayipi kawoyela kulindeleke ukuthi isebenze ngokungafanele amashumishumi eminyaka, ukuthutha uwoyela ngaphandle kokuvuza noma ukwehluleka. I-HSAW idlala indima ebalulekile ekuzuzeni impilo yenkonzo ende ngokuqinisekisa ngisho nokusatshalaliswa kokushisa kwe-welding, ukunciphisa ukugxila kwe-welding, nokuvimbela ukuqaliswa kokuqhekeka nokusakazeka - zonke izinto ezifaka isandla ekuthembekeni okuphelele kwepayipi.

    I-3. Ukwakhiwa okusebenzayo: I-HSAW iyakwazi ukuqhubeka nokushiswa kwezingxenye ezinde zepayipi, ngakho-ke isebenza kahle ePipeline Construction. Le ndlela inciphisa isikhathi se-welding, ikhulisa umkhiqizo, yehlisa kakhulu izindleko zokwakha, futhi ilungele ukuqedwa kwephrojekthi okufika ngesikhathi.

    4. Okunciphise ukulungiswa nokulungiswa: Ngokuhlinzeka ngama-welds asezingeni eliphakeme, amahhala, i-hsaw inciphisa isidingo sokulungiswa okuzayo noma ukulungiswa okuhlobene nokugcina. Amapayipi kawoyela akhiwa usebenzisa le ndlela athambekele ekuvuzeni noma ukwehluleka, ukwenza ngcono ukuphepha nokwanda kokusebenza kahle.

    I-5. Izinzuzo zezemvelo: I-HSAW iqinisekisa ukukhiqizwa kwama-welds anembile ngokunemba okuphezulu. Lokhu kunciphisa amathuba okugqwala kwamapayipi kanye nokuvuza kwamafutha alandelayo, ukuvikela imvelo ngezinhlekelele ezingaba khona ezihlotshaniswa nokwehluleka kwepayipi.

    a. Indlela ye-deoxidation iqokwa kanjena:

    I-FF: Insimbi ebulewe ngokuphelele equkethe izinto ezibophayo ze-nitrogen ngamanani anele ukubopha i-nitrogen etholakalayo (isib

    b. Inani eliphakeme le-nitrogen alisebenzi uma ukwakheka kwamakhemikhali kukhombisa okuqukethwe okuphelele kwe-AL ye-AL ye-0,020% ngesilinganiso esingu-2: 1, noma uma kungenjalo ezinye izinto ezibophayo ze-N zikhona. Izinto ezibophayo ze-N-Bonding zizoqoshwa kudokhumenti lokuhlola.

    Ekuphetheni:

    Ukwakhiwa kwamapayipi kawoyela kudinga amazinga aphezulu kakhulu we-welding ukuqinisekisa isikhathi eside, ukuthembeka nokuphepha. Kuvunguza i-arcged arc yelding (HSAW) ubuchwepheshe obufakazelwe bokuzikhethela kulo mkhakha ngenxa yekhono labo lokwakha ama-welds aqinile, aqinile futhi angenasici. Ngezinzuzo eziningi kufaka phakathi ubuqotho besakhiwo obuthuthukisiwe, ukwakhiwa okusebenzayo, ukuncishiswa kokulondolozwa kanye nezinzuzo zemvelo, i-hsaw idlala indima enkulu ekuhlangabezaneni nezidingo zokuhamba kawoyela zomhlaba wonke. Njengoba imboni kawoyela iyaqhubeka nokwanda, ukusetshenziswa kobuchwepheshe obuthuthukile be-welding obusezingeni eliphezulu njenge-HSAW kubalulekile ekugcineni ubuqotho kanye nokwethenjwa kwamapayipi kawoyela emhlabeni jikelele.

    Ipayipi le-SSAW

    Ngokufigqiwe

    I-Cangzhou Spiral Steel Pipe Group Co, Ltd. Uyaziqhenya ngokuhlinzeka ngamapayipi asezingeni eliphakeme kakhulu we-Spane Seam ngezinhlelo zokusebenza ezahlukahlukene. Sigxile ekukhiqizeni okunembile, ubuchwepheshe obuthuthukisiwe be-welding kanye nezinto zokwakha ezisezingeni lokuhlinzeka amakhasimende ngezixazululo ezithembekile, ezisebenzayo zezidingo zazo zamapayipi. Sithembe ukuba sihlangabezane nazo zonke izidingo zakho kanye nesipiliyoni sokuqala ukuthembeka nokuqina kwamapayipi ethu esivunguvu.
