Miyezo ya API 5L ndi ASTM A53:Miyezo iyi imawonetsetsa kuti chitoliro chachitsulo chikukwaniritsa zofunikira zomwe zimagwiritsidwa ntchito pamakampani amafuta ndi gasi, komanso kugwiritsidwa ntchito pafupipafupi pamakina ndi kukakamiza.
Gulu B:Mawu akuti "Grade B" akuwonetsa mphamvu ndi makina a chitoliro chachitsulo, chomwe chili ndi zofunikira zenizeni za mphamvu zokolola, kulimba kwamphamvu, komanso mphamvu.

Kuwotcherera kwa SAW:Chitolirocho chimapangidwa pogwiritsa ntchito njira ya Submerged Arc Welding (SAW), yomwe imaphatikizapo kupanga msoko wowotcherera pogwiritsa ntchito njira yowotcherera ya arc mosalekeza. Njirayi imadziwika popanga ma welds apamwamba kwambiri, mayunifolomu.
Paint Yakuda Yomaliza:Kupaka utoto wakuda kumapereka kukana kwa dzimbiri komanso kumawonjezera kukongola kwa chitoliro chachitsulo. Utotowo umathandizanso kuteteza chitoliro panthawi yosungira ndi kuyendetsa.
Mapulogalamu:API 5L ASTM A53 Gulu B Black Painted SAW Welded Steel Pipe imagwiritsidwa ntchito kwambiri pazinthu zosiyanasiyana, kuphatikiza mapaipi otumizira mafuta ndi gasi, kuthandizira pakumanga, ndi ntchito zina zamafakitale ndi zamakina.
