Chitoliro chowongoka chokhala ndi mbali ziwiri cholumikizidwa ndi arc welded ndiChitoliro cha JCOEChitoliro chachitsulo cholunjika cholumikizidwa chimagawidwa m'magulu awiri kutengera njira yopangira: chitoliro chachitsulo cholunjika cholumikizidwa pafupipafupi komanso chitoliro chachitsulo cholumikizidwa ...Mapaipi achitsulo a LSAW, ndi zina zotero kutengera njira zawo zopangira. Njira yopangira mapaipi a JCOE ndi yosavuta, yokhala ndi ntchito yabwino kwambiri yopangira, ndalama zochepa, komanso chitukuko chachangu.
Chitoliro cha JCOE ndi chimodzi mwa njira zopangira mapaipi achitsulo chowongoka, komanso chimodzi mwa zida. Ku China, GB/T3091-2008 ndi GB/T9711.1-2008 zimagwiritsidwa ntchito kwambiri, pomwe API-5L ndiye muyezo wapadziko lonse lapansi. Chitoliro cha JCOE chimapangidwa makamaka pogwiritsa ntchito welding ya arc yonyowa mbali zonse ziwiri. Kuti akwaniritse zofunikira za miyezo yoyenera, zinthuzo zimadutsa m'njira zosiyanasiyana monga kupindika, kulumikizana, kuwotcherera mkati, kuwotcherera kunja, kuwongola, ndi malekezero athyathyathya.
Mapulojekiti akuluakulu a mapaipi, mapulojekiti otumizira madzi ndi gasi, kumanga maukonde a mapaipi m'mizinda, nyumba zopangira zitsulo, kuyika mipiringidzo m'milatho, kumanga ma municipalities, ndi kumanga mizinda zonse zimagwiritsa ntchito mapaipi a JCOE.
