Lub luj tshib NB150 LR 90 degree SCH40, ASTM A234 WPB

Lub luj tshib NB150 LR 90 degree SCH40:

"Lub luj tshib": Qhov no qhia tau hais tias qhov haum yog zoo li lub luj tshib, tso cai rau kev hloov pauv hauv cov kav dej.

"NB150": Qhov no qhia txog qhov nominal bore loj ntawm qhov haum, uas yog 150. Qhov nominal bore loj sawv cev rau kwv yees li hauv txoj kab uas hla ntawm cov yeeb nkab haum yog tsim los txuas rau.

"LR 90 degree": LR stands rau "ntev vojvoog," qhia lub vojvoog ntawm qhov khoov ntawm lub luj tshib. Lub luj tshib 90 degree LR txhais tau hais tias nws ua rau 90-degree tig nrog lub vojvoog ntev, muab cov dej ntws zoo dua piv rau lub luj tshib luv (SR) lub luj tshib.

"SCH40": Qhov no yog hais txog cov yeeb nkab teem caij lossis phab ntsa tuab ntawm qhov haum. SCH40 qhia txog tus qauv phab ntsa tuab raws li ASME cov qauv.

Lub luj tshib Dimensions:

Lub luj tshib muaj qhov nominal bore (NB) qhov loj ntawm 150 thiab lub vojvoog ntev (LR) 90 degree khoov. Nws yog tsim los kom haum cov kav dej nrog Schedule 40 (SCH40) thickness. Txheem qhov ntev ua raws li ASME B16.9 lossis cov qauv zoo sib xws.

Khoom piav qhia:

Lub luj tshib yog tsim los ntawm ASTM A234 WPB, uas yog tus qauv specification rau wrought carbon steel thiab alloy steel yeeb nkab fittings rau nruab nrab thiab high-temperature kev pab cuam.

Tooj liab (Cu): 0.40% max

Vanadium (V): 0.08% max

Mechanical Properties:

ASTM A234 WPB feem ntau nthuav tawm cov khoom nram qab no:

Tensile zog: 60, 000-85, 000 psi

Yield zog: 30, 000-65, 000 psi

Elongation: 22% min

Pipe Fitting Inspection Considerations:

Kev tshuaj xyuas qhov pom ntawm qhov tsis xws luag xws li tawg, porosity, lossis irregularities.

Dimensional checks los xyuas kom meej raws li specifications.

Kev kuaj tsis yog kev puas tsuaj (NDT) txoj hauv kev xws li kev kuaj hluav taws xob lossis kev kuaj ultrasonic txhawm rau kuaj pom qhov tsis zoo.

Daim Ntawv Thov Ntau:

Lub luj tshib nrog cov kev qhia tshwj xeeb no feem ntau siv rau hauv ntau yam kev lag luam, suav nrog roj thiab roj, petrochemical, tsim hluav taws xob, thiab kev tsim kho.

Common Q&A:

Q: ASTM A234 WPB lub luj tshib tuaj yeem tiv taus qhov kub thiab txias? A: Yog lawm, ASTM A234 WPB lub luj tshib yog tsim los rau kev pabcuam nruab nrab thiab kub kub, ua rau lawv haum rau ntau yam kev siv.

Q: Qhov txawv ntawm LR (Long Radius) thiab SR (Short Radius) lub luj tshib yog dab tsi? A: LR lub luj tshib muaj lub vojvoog ntev dua, muab cov dej ntws zoo dua thiab tsis muaj zog dua piv rau SR lub luj tshib, uas muaj lub vojvoog luv dua.

Q: Puas yog ASTM A234 WPB fittings haum rau vuam? A: Yog, ASTM A234 WPB fittings feem ntau welded siv ntau yam vuam txheej txheem xws li nplaum vuam, MIG vuam, los yog TIG vuam.

SSM Peev Xwm:
