    Mzere wathu wozunguliramachubu olumikizidwaamapangidwa mosamala. Kuyambira ndi zingwe zachitsulo kapena mbale zozungulira, timapinda ndikusandutsa zinthuzi kukhala zozungulira. Kenako timazilumikiza pamodzi kuti zipange chitoliro cholimba. Pogwiritsa ntchito njira zosiyanasiyana zolumikizira monga arc welding, timatsimikizira kuti zinthu zathu zimakhala zolimba komanso zolimba.

    Mapaipi olumikizidwa mozungulira ali ndi ubwino wambiri kuposa mapaipi achitsulo osapindika. Chofunika kwambiri, ndi otsika mtengo komanso opindulitsa kwambiri. Mapaipi awa amachepetsa ndalama zopangira popanda kuwononga magwiridwe antchito. Kuphatikiza apo, athumapaipi achitsulo ozungulira olumikizidwa onetsetsani kuti kuyika kwake kuli kosavuta chifukwa sikufunikira njira zovuta komanso zowononga nthawi.

    Ku Cangzhou Spiral Steel Pipes Group Co., Ltd., timanyadira njira zathu zowongolera khalidwe. Kuyambira kusaina pangano mpaka kugula zinthu zopangira, kupanga, kuyang'anira, ndi ntchito yogulitsa, sitepe iliyonse imayendetsedwa mosamala.
