Mfundo zathu ndi zakuti, khalidwe labwino komanso mbiri yabwino ya ngongole, zomwe zingatithandize kukhala paudindo wapamwamba. Kutsatira mfundo yakuti "ubwino choyamba, ogula apamwamba" ya fakitale yogulitsa kwambiri ya China Welded SSAW Hasw Steel Tube & Black Spiral Steel Pipe, kuti tipeze zabwino zonse, bungwe lathu likulimbikitsa kwambiri njira zathu zolumikizirana padziko lonse lapansi pankhani yolankhulana ndi ogula akunja, kutumiza mwachangu, khalidwe labwino kwambiri komanso mgwirizano wanthawi yayitali.
Mfundo zathu ndi zakuti "ubwino ndi wabwino komanso mbiri yabwino ya ngongole." Izi zingatithandize kukhala ndi udindo wapamwamba. Kutsatira mfundo yakuti "ubwino choyamba, ogula apamwamba"API 5L SSAW, China SSAWKatundu watumizidwa ku Asia, Middle-eastern, Europe ndi Germany. Kampani yathu yakhala ikutha kusintha magwiridwe antchito ndi chitetezo cha katundu kuti ikwaniritse misika ndikuyesetsa kukhala pamwamba pa A pa khalidwe lokhazikika komanso utumiki wowona mtima. Ngati muli ndi ulemu wochita bizinesi ndi kampani yathu, tidzachita zonse zomwe tingathe kuti tithandizire bizinesi yanu ku China.
Chitoliro cholumikizidwa ndi spiral chimapangidwa kuchokera ku coil yachitsulo. Coil imatsegulidwa kenako imalumikizidwa pamene ikusinthidwa kukhala mawonekedwe a chitoliro. Kusintha ngodya ya spiral ndi makulidwe a coil ndiko komwe kumafunikira kuti musinthe kuchokera pa kukula kwa chitoliro chimodzi kupita ku china. Mbali ziwiri za double submited arc weld zimalowa mu makulidwe onse a chitsulo kuti zitsimikizire mphamvu ya chitoliro chomalizidwa. Mayeso athunthu awonetsa kuti chitoliro cholumikizidwa ndi spiral chapamwamba kwambiri ndi cholimba ngati chitoliro cha API. Mphamvu ndi kusinthasintha kwa kupanga chitoliro cholumikizidwa ndi spiral kumapangitsa kuti chikhale chinthu chosankhidwa pa ntchito zosiyanasiyana.

Chitoliro cha SSAW (Spiral Submerged Arc-Welding Pipe), chomwe chimatchedwanso HSAW pipe (Helical SAW), chomwe chimagwiritsa ntchito mzere wolumikizira ngati helix. Chikugwiritsa ntchito ukadaulo womwewo wa Submerged Arc-Welding ndi chitoliro cha LSAW. Njira yopangira ndikuzungulira mzere wachitsulo, kuti njira yozungulira ikhale ndi ngodya yofanana ndi njira ya pakati pa chitoliro, kupanga ndi kuwotcherera, kotero kuti msoko wowotcherera ukhale mu mzere wozungulira.
