Izinqubo ze-Ssaw Steel Pipe Welding for Gines kagesi

Izinqubo ze-Ssaw Steel Pipe Welding ze-Lines Lines efakiwe

Incazelo emfushane:

Uma kukhulunywa ngokufakwa kwePutro Pipeline, ukuqinisekisa ukuphepha nokwethembeka kohlelo kubalulekile. Isici esibalulekile senqubo inqubo ye-welding esetshenziselwa ukujoyina izakhi ezahlukahlukene zepayipi legesi, ikakhulukazi uma usebenzisa ipayipi lensimbi ye-Ssaw. Kule bhulogi, sizokwelulela ukubaluleka kwezinqubo ezifanele ze-welding ze-welding ekufakweni kwegesi isebenzisa ipayipi lensimbi ye-SSAW.

Imininingwane Yomkhiqizo

Amathegi Omkhiqizo

Ipayipi lensimbi le-Ssaw, eyaziwa nangokuthi ipayipi elifakwe emanzini angena ngaphakathi, livame ukusetshenziswa ekufakweni kwamapayipi wegesi ngenxa yokuqina kwalo namandla. Kodwa-ke, ukusebenza kwalawa mapayipi kuncike kakhulu kwikhwalithi yezinqubo ze-welding ezisetshenziswe ngesikhathi sokufakwa. Amasu wokufaka ama-welding angafanele angaholela ekuhlanganiseni okubuthakathaka futhi onakele, okuholela ezingozini zokuphepha kanye nokwehluleka kohlelo.

Enye yezinto ezibalulekile ekuqinisekiseni ubuqotho bokufakwa kwegesi yepayipi usebenzisa ipayipi lensimbi elisezingeni eliphansi le-WELDC Lokhu kufaka ukucubungula ngokucophelela izindlela ze-welding, izinto zokugcwalisa kanye nokulungiselela okwedlule. Ngaphezu kwalokho, ukuthobela amazinga nemithethonqubo yezimboni kubalulekile ekuqinisekiseni ukwethenjwa nokuphepha kweumugqa wegesisizinhlelo.

Ukulungiselela okufanelekile kwe-welding kubalulekile ukuqinisekisa ukufudumeza okuphumelelayo kwamapayipi ensimbi angenamikhawulo e-arC Lokhu kubandakanya ukuhlanza okuphelele nokuhlola indawo yepayipi ukususa noma yikuphi ukungcola noma iziphambeko ezingathinta ikhwalithi ye-weld. Ngaphezu kwalokho, ukufeza i-weld eqinile nethembekile, ipayipi kufanele lilinganiswe ngokunembile futhi lihambisane.

Ngesikhathi senqubo yangempela ye-welding, ukunaka imininingwane nokubambelela ukulungisa inqubo efanele kubalulekile. Ukukhetha indlela efanelekile ye-welding, noma ngabe i-tig (tungsten inert gas welding), i-mig (insimbi inert gas welding) noma i-smaw (stick arc welding), kufanele ikhethwe ngokusekelwe kwizidingo ezithile zokufakwa kwepayipi legesi. Ngokwengeziwe, ukusetshenziswa kwezinto ezisezingeni eliphakeme kakhulu kanye nezinqubo ezicophelela ze-welding zibalulekile ekukhiqizeni ama-weld athembekile futhi ahlala isikhathi eside ahlangabezana nezidingo zomsebenzi wePipeline imisebenzi.

Ngokwengeziwe, ukuhlolwa kwe-Post-Weld kanye nokuhlola kuyizinyathelo ezibalulekile zokuqinisekisa ikhwalithi ye-welld nobuqotho ekufakweni kwamapayipi wegesi usebenzisa ipayipi lensimbi ye-SSAW. Izindlela zokuhlola ezingezona ezonakalisayo, njengokuhlolwa kwe-radiographic kanye nokuhlolwa kwe-ultrasonic, kungasiza ukukhomba noma yiziphi izici ezingaba khona noma ukunqanyulwa kwamalunga ahlanganisiwe ukuze zilungiswe ngokushesha futhi ziqinisekise ukuthembeka kohlelo lwakho lwe-piping yegesi.

Ngamafuphi, izinqubo ezifanele ze-welding zibalulekile ekufake imigqa yegesi usebenzisa amapayipi ensimbi afakwe emanzini angenalutho. Ubuqotho kanye nokuphepha kohlelo lwakho lwe-Piping Piping kuncike kwikhwalithi ye-welding yakho, ngakho-ke amazinga emboni we-welding kanye nemikhuba emihle kufanele kulandelwe. Ngokubeka phambili amasu afanele ama-weld afanele, amasu we-welding acebile, kanye nokuhlolwa okuphelele kwe-weld, ukufakwa kwamapayipi wegesi kungaqinisekisa ukuthembeka nokuphepha kokufakwa kwepayipi kwensimbi ye-SSAW yegesi yePipeline application.
