Manje sinethimba elinekhono, elisebenzayo lokuhlinzeka ngezinsizakalo ezisezingeni elihle kumthengi wethu. Sivame ukulandela umgomo wentengo ekhethekile ye-SSAW/Sawl API 5L Spiral Welded Carbon Steel Pipeline, igesi yemvelo kanye nepayipi lamafutha, egxile kumakhasimende ethu. Ngaphezu kwalokho, singaqondisa amakhasimende kahle ngamasu okusebenzisa ukuze samukele izixazululo zethu kanye nendlela yokukhetha izinto ezifanele.
Manje sinethimba elinekhono, elisebenzayo lokuhlinzeka ngezinsizakalo ezisezingeni elihle kumakhasimende ethu. Sivame ukulandela umgomo wokugxila kumakhasimende, ogxile emininingwaneni.Ipayipi Lensimbi laseShayina i-LSAW/SSAW kanye nepayipi elihlanganisiwe, Umsebenzi wethu ukuletha inani eliphakeme njalo kumakhasimende ethu nakumakhasimende abo. Lokhu kuzibophezela kugcwele konke esikwenzayo, kusishukumisela ukuba sithuthukise futhi sithuthukise izixazululo zethu kanye nezinqubo zokufeza izidingo zakho.
Amapayipi a-odiwe ngaphansi kwale ncazelo asetshenziselwa isevisi yokucindezela okuphezulu emazingeni okushisa omoya naphansi. Asetshenziswa kakhulu ekudlulisweni kukawoyela negesi yemvelo.
Ipayipi Lensimbi Yekhabhoni le-ASTM A671 LSAW(JCOE) kufanele libe ama-weld afakwe kabili, angena ngokugcwele enziwe ngokuhambisana nezinqubo kanye nabashiseli noma opharetha bokushisela abafanelekile ngokuhambisana ne-ASME Boiler kanye ne-Pressure Vessel Code, Isigaba IX.
Zonke izinhlobo ngaphandle kuka-10, 11, 12 kanye no-13 kufanele ziphathwe ngokushisa esithandweni somlilo esilawulwa ku-±15℃ futhi zifakwe i-hydrometer yokurekhoda ukuze kutholakale amarekhodi okushisa.
Ukukhiqiza: Amapayipi ensimbi e-LSAW(JCOE)
Usayizi: OD: 406~1500mm Isisindo: 6~40mm
Ibanga: CB60, CB65, CC60, CC65, njll.
Ubude: 12M noma ubude obucacisiwe njengoba kudingeka.
Iziphetho: Isiphetho Esilula, Isiphetho Esigobile, Esinemiphetho Emikhulu;
