WP304, WP304L, WP316, WP316L, WP321 thiab lwm yam ASTM A403 / ASTM A403M -2018 yog tus qauv specification rau wrought austenitic stainless hlau piping fittings. |
2 nti stainless hlau tee tsim:
Forming-Forging lossis shaping kev ua haujlwm yuav yog tsim los ntawm hammering, nias, tho, extruding, chim siab, dov, dabtsi yog khoov, fusion vuam, machining, los yog ua ke ntawm ob los yog ntau tshaj ntawm cov haujlwm no. Kev tsim cov txheej txheem yuav tsum tau siv kom nws yuav tsis tsim kev puas tsuaj ntawm 2 nti stainless hlau tee.
Yuav tsum muaj tag nrho cov yeeb nkab welds ua los ntawm zeb los yog cov chaw tsim khoom haum nrog kev sib ntxiv ntawm cov xov tooj cua hlau xov tooj cua graphically tshuaj xyuas thoob plaws qhov ntev.
5.4.2 Xov tooj cua graphic soj ntsuam tsis tas yuav tsum tau ntawm ib leeg
longitudinal seam welds ua los ntawm cov pib yeeb nkab chaw tsim tshuaj paus yog ua tsis tau ntxiv cov muab tub lim hlau; thiab
5.4.3 Xov tooj cua graphic soj ntsuam tsis tas yuav tsum tau ntawm longitudinal seam fusion welds ua los ntawm cov chaw tsim khoom haum thaum
tag nrho cov xwm txheej hauv qab no tau ua tiav:
5.4.3.1 tsis ntxiv cov khoom siv hlau,
5.4.3.2 tsuas yog ib qho welding dhau ib qho vuam seam, thiab,
5.4.3.3 fusion vuam los ntawm ib sab nkaus xwb.
5.4.4 Nyob rau hauv qhov chaw ntawm xov tooj cua graphic xeem, welds ua los ntawm 2 nti stainless hlau tee chaw tsim tshuaj paus tej zaum yuav raug kuaj ultrasonically raws li Txoj Cai yuav tsum tau teev nyob rau hauv 5.6.
5.5 Qib WP fittings xaj raws li Chav Kawm WX yuav tsum ua raws li qhov yuav tsum tau ua ntawm ASME B16.9 lossis B16.28 thiab yuav tsum muaj tag nrho cov welds, txawm yog tsim los ntawm cov chaw tsim khoom haum lossis cov chaw tsim khoom pib, xov tooj cua kuaj xyuas thoob plaws hauv lawv qhov ntev raws li kab lus UW-51 ntawm Tshooj VIII, Division I, ntawm ASME Boiler thiab Pressure Vessel Code.
5.6 Qib WP fittings xaj raws li Chav Kawm WU yuav tsum ua kom tau raws li qhov yuav tsum tau muaj ntawm ASME B16.9 lossis B16.28 thiab yuav tsum muaj tag nrho cov welds, txawm tias tsim los ntawm cov chaw tsim khoom haum lossis cov chaw tsim khoom pib, ultrasonically tshuaj xyuas thoob plaws lawv qhov ntev raws li Daim Ntawv Ntxiv 12 ntawm Tshooj VIII, Division 1 ntawm ASME Boiler thiab Pressure Vessel Code.
