ASME B16.9 hla kev, tseem hu ua plaub - txoj kev cov yeeb nkab hla, yog cov yeeb nkab tseem ceeb siv los txuas plaub lub kav dej ntawm lub kaum sab xis. Nws ua kom muaj ntau- cov kua dej los yog roj ntws hauv cov kav dej. HT PIPE yog ib tug thawj coj stockist thiab thoob ntiaj teb exporter nrog ntau tshaj 15 xyoo ntawm kev txawj ntse nyob rau hauv thoob ntiaj teb kev lag luam. Peb muab cov kav dej, daim hlau, cov kab tuav, thiab ntau yam ntawm cov yeeb nkab fittings, flanges, thiab li qub.Tiv tauj pebtam sim no rau cov quotes dawb thiab cov ntaub ntawv khoom ntiag tug.
Dimensional Tolerances rau ASME B16.9 Hla
Centerline-rau-Face Length (C Dimension) kam rau ua:Rau NPS 1/2 txog NPS 24 (DN 15 txog DN 600), qhov kam rau ua yog ± 1/8 nti (± 3.2 hli). Rau NPS 26 txog NPS 48 (DN 650 txog DN 1200), qhov kam rau ua yog ± 3/16 nti (± 4.8 hli).
Vuam End OD Tolerance:± 0.010 nti (± 0.25 hli) rau NPS txog NPS 2 (DN 50). ± 0.020 nti (± 0.51 hli) rau NPS 2-12 (DN 50-300). ± 0.030 nti (± 0.76 hli) rau NPS 14 thiab siab dua (DN 350 thiab siab dua).
Phab ntsa Thickness kam rau ua:Qhov tsawg kawg nkaus phab ntsa thickness yuav tsum tsis pub tsawg tshaj 90% ntawm qhov tsawg kawg nkaus phab ntsa thickness. Qhov siab tshaj plaws ntawm phab ntsa tsis tau teev tseg tab sis yuav tsum tsis txhob cuam tshuam nrog kev vuam lossis cov yeeb nkab sib dhos.
Bevel Angle Tolerance:± 2.5℃los ntawm qhov teev 37.5℃kaum. Hauv paus lub ntsej muag qhov ntev kam rau ua yog ± 1/32 nti (± 0.79 hli).
Dimensional Verification Tests
Kev tshuaj xyuas qhov muag:Tshawb xyuas qhov tsis xws luag ntawm qhov chaw thiab qhov dav dav dav ntawm cov ceg.
Dimensional Kev Ntsuas:Siv cov cuab yeej precision (piv txwv li, calipers, micrometers, daim kab xev ntsuas, kev sib koom tes ntsuas tshuab) los txheeb xyuas qhov nruab nrab- mus rau - lub ntsej muag ntev, vuam kawg OD, phab ntsa thickness, bevel kaum sab xis, thiab hauv paus lub ntsej muag dimension.
Radiographic Testing (RT) lossis Ultrasonic Testing (UT):Rau welded crosses, RT los yog UT yog siv los soj ntsuam cov weld defects uas tuaj yeem cuam tshuam qhov kev ruaj ntseg los yog kev ua haujlwm zoo.
Material Test Reports (MTRs):Muab cov ntaub ntawv pov thawj ntawm cov khoom siv tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom siv kho tshuab, uas ua kom tsis muaj kev sib haum xeeb.
