Dab tsi yog qhov yuav tsum tau ceev faj thaum weldingween ASME SA387|Qib 5 Chav Kawm 1?
Cov kev ceev faj tseem ceeb suav nrog kev ua kom sov ua ntej thiab tom qab-weld heat treatment (PWHT) los tswj cov chromium- cov ntsiab lus molybdenum, siv cov khoom siv sib xyaw ua ke, ua kom huv si (tsis muaj roj / roj), tswj cov cua sov, tswj qhov cua, thiab ua kom tiav NDT/mechanical testing. nram qab no ASME code
ASME SA387 yog dab tsi|Qib 5 Chav Kawm 1 cov khoom siv?
ASME SA387 Qib 5 Chav Kawm 1 yog ib hom chromium-molybdenum (Cr-Mo) alloy steel phaj tsim los rau fabricating weldable siab hlab ntsha thiab boilers siv nyob rau hauv siab - kub, siab - kev siv siab, muab zoo heev high -temp lub zog thiab corrosion kuj.
Yuav Tsum Muaj Kev Xeem Li Cas ASME SA387|Qib 5 Chav Kawm 1?
Rau ASME SA387 Qib 5 Chav Kawm 1, kev sim tshuaj muaj xws li tshuaj ntsuam xyuas, kev ntsuas tensile (lub zog, tawm los, elongation), thiab kev ntsuam xyuas cuam tshuam, nrog rau kev tshuaj xyuas qhov muag rau qhov tsis xws luag, txhua yam ua tom qab kev kho cua sov (xws li Normalizing & Tempering).
