Cov yeeb nkab xaj raws li qhov tshwj xeeb no yuav tsum haum rau kev khoov, flanging, thiab kev ua haujlwm zoo sib xws, thiab rau vuam.Thaum cov hlau yuav tsum tau welded, nws yog presupposed hais tias ib tug welding txheej txheem haum rau qib ntawm steel thiab npaj siv los yog kev pab cuam yuav siv.
ASTM A106 seamless steel yeeb nkab yog tsim los ntawm txias-draw los yog kub dov, raws li tau teev tseg.
Kub tiav yeeb nkab yuav tsum tsis txhob kub kho.Thaum kub tiav cov yeeb nkab tau kho cua sov, nws yuav tsum tau kho cua sov ntawm qhov kub ntawm 1200 ° F lossis siab dua.Cov yeeb nkab txias txias yuav tsum tau kho cua sov tom qab qhov kawg txias txias dhau ntawm qhov kub ntawm 1200 ° F lossis siab dua.
