Astm A106 Seamless Siab Yeeb Yeeb

ASTM A106 seamless siab yeeb nkab (tseem hu ua ASME SA106 yeeb nkab) feem ntau yog siv rau hauv kev tsim cov roj thiab roj txig, cov chaw ua haujlwm fais fab, cov nroj tsuag petrochemical, lub rwj dej, thiab cov nkoj uas cov kav xa dej yuav tsum thauj cov kua thiab cov pa uas muaj qhov kub thiab qhov siab dua Cov.

ASTM A106 Seamless Siab Yeeb Nkab (tseem hu ua ASME SA106 yeeb nkab) npog npog cov hlau tsis muaj steel nominal phab ntsa yeeb nkab rau qhov chaw kub-txias. Haum rau khoov, flanging thiab zoo sib xws cov haujlwm.

ASTM A106 Qib B qhov sib npaug yog sib piv rau ASTM A53 Qib B thiab API 5L B ntawm cov khoom siv tshuaj thiab cov khoom siv, feem ntau siv cov pa roj carbon steel thiab yiled lub zog yam tsawg kawg nkaus 240 MPa, tensile lub zog 415 Mpa.

Cov qauv ntsuas rau ASTM A106 A, B, C yog kev ntsuas kev ntsuas phom, ntsuas hydrostatic, ntsuas qhov tsis zoo, ntsuas hluav taws xob, ntsuas tsis tau tam sim no, ntsuas flux paim quav, cov txheej txheem ntsuas no yuav tsum ceeb toom lossis sib tham nrog tus neeg siv kom paub meej tias hom dab tsi yuav muaj xeem.
