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 (Chozungulira ChomizidwaChitoliro cha Arc Welded Steel), yomwe imatchedwanso HSAW pipe (Helical SAW), mzere wolumikizira wofanana ndi helix. Ikugwiritsa ntchito ukadaulo womwewo wa welding wa Submerged Arc-Welding ndi LSAW pipe. Njira yopangira ndikuzungulira mzere wachitsulo, kuti njira yozungulira ikhale ndi ngodya yofanana ndi njira ya pakati pa chitoliro, kupanga ndi kuwotcherera, kotero kuti msoko wolumikizira uli mu mzere wozungulira.

Chitoliro chathu cholumikizidwa chimadalira akatswiri ndi ntchito zosiyanasiyana za eni nyumba. Chitoliro cholumikizidwa Ndi mtundu wa chida cholimba (1.15-22 mm)Chitoliro chachitsulo, yomwe ndi yolimba ndipo ingagwiritsidwe ntchito padenga ndipo mapaipi oyenda amalimbikitsidwanso pa: Chitoliro cha boiler, chitoliro chobowolera, chitoliro cha hydraulic, chitoliro cha gasi, chitoliro cha mafuta, chitoliro cha feteleza, chitoliro chomangira. Chitoliro chapadera cha kapangidwe kake chimatha kupirira mayeso a nyengo yamitundu yonse, ndipo chimatha kupakidwa utoto kapena kukalamba kuti chipeze zotsatira zosiyanasiyana zosangalatsa. Chitoliro cholumikizidwacho ndi chopepuka, chosavuta kugwiritsa ntchito komanso chonyamulidwa. Chopepuka komanso chopyapyala, chosavuta kugwiritsa ntchito kapena kunyamulidwa; chosavuta kudula m'njira wamba.
