SSAW(yomwe imadziwikanso kutiSAWHChitoliro chachitsulo chimatanthauza chitoliro chachitsulo chozungulira cholumikizidwa ndi msoko wozungulira womwe uli pansi pa arc.
Njira yopangira chitoliro chachitsulo chamtunduwu imaphatikizapo kupotoza mbale zachitsulo nthawi zonse kukhala mawonekedwe ozungulira ndikulumikiza m'mphepete mwa mbalezo pamodzi pogwiritsa ntchito welding yamkati ndi yakunja yolowetsedwa pansi kuti apange msoko wozungulira wa chitolirocho.
Mtundu uwu wa chitoliro chachitsulo umadziwika ndi kukhala ndi msoko wozungulira, ndipo kupanga kwake bwino kwambiri kumapangitsa kuti ukhale woyenera kupanga mapaipi achitsulo akuluakulu.
Botop Steel ndi kampani yopanga mapaipi achitsulo opangidwa ndi zitsulo komanso yogulitsa kuchokera ku China, yomwe imapereka mitundu yosiyanasiyana ya mapaipi achitsulo omwe angasinthidwe kuti akwaniritse zofunikira pa polojekiti yanu.
Zinthu za SSAW zomwe tingapereke ndi monga chitoliro chachitsulo chozungulira cha API 5L, ASTM A252, EN 10217, GB/T 9711, ndi miyezo ina yambiri. Kuphatikiza apo, timapereka ntchito zingapo kuphatikizapo kukonza chitoliro chachitsulo, kuyika flanging, zolumikizira chitoliro, zokutira, kupukuta ndi shot peening, ndi zina zambiri.
Ubwino wapadera wa machubu a SSAW ndi kuthekera kopanga machubu akuluakulu mpaka 3,500 mm, zomwe sizingatheke ndi mitundu ina ya machubu.
Kuphatikiza pa izi, machubu a SSAW ali ndi ubwino wa liwiro lopanga mwachangu, kuthekera kopanga machubu m'litali lalitali, komanso ntchito zosiyanasiyana.
Kupanga chitoliro chachitsulo cha SSAW ndi njira yodziyimira yokha, yomwe sikuti imangowonjezera bwino ntchito yopanga chitoliro chachitsulo, komanso imatsimikizira kuti chinthucho chili ndi mulingo wapamwamba kwambiri.
Nthawi zina SSAW imatchedwaDSAWchifukwa njira yowotcherera imachitika pogwiritsa ntchito ukadaulo wowotcherera wa arc wodzazidwa ndi mbali ziwiri.
