This specification covers carbon and alloy steel pipe, electric-fusion-welded with filler metal added, fabricated from the pressure-vessel-quality plate of several analyses and strength levels, and suitable for high-pressure service at high temperatures. Kev kho cua sov yuav lossis tsis tuaj yeem yuav tsum tau ua kom muaj cov khoom siv yam xav tau lossis ua raws li cov cai siv tau. Cov cai yuav tsum muaj rau kev siv thaum kuaj ntxiv lossis kev kuaj mob yog xav tau.
Qhov tshwj xeeb hu rau cov yeeb nkab coj 16 nyob rau hauv. [400 mm] nyob rau sab nraum lub taub thiab loj dua nrog phab ntsa thicknesses txog li 3 hauv. [75 hli] suav. Cov kav dej muaj lwm qhov ntev yuav muab rau nws ua raws txhua yam ntawm cov lus qhia tshwj xeeb.
