Tuam Tshoj Sch40 A53 A106 API 5L Seamless thiab Welded Carbon Steel Yeeb Nkab
Txheej txheem cej luam
Peb txoj kev mus nyob mus ib txhis yog tus cwj pwm ntawm "hais txog kev ua lag luam, saib cov kev cai, saib xyuas kev tshawb fawb" nrog rau txoj kev xav ntawm "zoo qhov yooj yim, muaj kev ntseeg nyob rau hauv thawj zaug thiab kev tswj hwm qib siab" rau Seamless thiab Welded Carbon Steel Pipe, Los ntawm txhais tau tias. ntawm peb txoj haujlwm nyuaj ua tiav, peb feem ntau tau tso siab los ntawm peb cov khoom siv steel yeeb nkab cov neeg siv khoom. Hu rau peb hnub no kom paub meej ntxiv! Peb pab neeg paub zoo txog kev ua lag luam xav tau hauv ntau lub teb chaws, thiab muaj peev xwm muab cov khoom tsim nyog ntawm tus nqi zoo tshaj plaws rau cov lag luam sib txawv. Peb lub tuam txhab twb tau teeb tsa ib pab kws tshaj lij, muaj tswv yim thiab lub luag haujlwm los tsim cov neeg siv khoom nrog ntau txoj cai yeej.
Daim ntawv thov
Nws yog siv rau kev quab yuam thiab qhov siab, thiab rau lub hom phiaj dav dav, dej, roj thiab cov kav dej.

A Qhov tsawg kawg nkaus elongation ntawm gauge ntev 2in. (50mm) yuav tsum tau txiav txim los ntawm cov qauv hauv qab no:
e=625000(1940)A0.2/U0.9
e = qhov tsawg kawg nkaus elongation ntawm lub ntsuas 2in. (50mm), qhov feem pua tawm mus rau qhov ze tshaj 0.5%;
A = Muab xam raws li cov txheej txheem sab nraud ntawm lub nominal raj los yog lub nominal dav ntawm cov qauv tensile thiab nws cov phab ntsa thickness, thiab sib npaug mus rau qhov ze tshaj plaws cross-sectional cheeb tsam ntawm lub tensile qauv ntawm 0.01 in.2 (1 mm2), thiab Nws muab piv nrog 0.75in.2 (500mm2), qhov twg me dua.
U = teev tsawg kawg nkaus tensile zog, psi (MPa).
