ASME B16.9 Ntev vojvoog rov qab khoov, raws li qhov tseem ceeb ntawm cov yeeb nkab tig txuas, muaj qhov ntsuas qhov ntev uas cuam tshuam ncaj qha rau kev sib dhos qhov tseeb, cov dej ntws ua haujlwm zoo, thiab kev nyab xeeb thiab ruaj khov ntawm cov kav dej.
Hais txog peb
HT PIPE yog ib tug thawj coj stockist thiab thoob ntiaj teb exporter nrog ntau tshaj 16 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.
Core Dimensions ntawm Ntev Radius Rov Qab Khoov
Nominal Pipe Size (NPS/DN):Txheeb xyuas qhov nominal loj ntawm cov yeeb nkab haum, tsis yog qhov tseeb sab hauv lossis sab nraud. Nws ua hauj lwm raws li lub hauv paus rau kev xaiv lwm qhov seem tsis.
Bending Radius (R):Lub vojvoog dabtsi yog khoov ntawm lub vojvoog ntev rov qab khoov yog kho ntawm 1.5 npaug ntawm nominal txoj kab uas hla (1.5 × DN). Qhov kev tsim no txo cov dej tsis kam thiab siab poob, ua rau nws tsim nyog rau cov kav dej nrog cov dej ntws siab lossis cov kua dej khov.
Sab nraud txoj kab uas hla (OD):Sab nraud txoj kab uas hla ntawm cov yeeb nkab ntawm lub bevels ntawm ob qho kawg ntawm qhov rov qab khoov yuav tsum precisely phim lub sab nraud ntawm cov yeeb nkab txuas.
Center-rau-End Distance (A):Qhov kev ncua deb ntawm qhov nruab nrab ntawm qhov rov qab khoov mus rau qhov kawg ntawm ob sab ncaj qha cuam tshuam rau qhov spatial layout ntawm cov yeeb nkab installation.
Center-rau-Center Distance (O):Rau 180℃ntev vojvoog rov qab khoov, qhov no yog hais txog qhov kev ncua deb ntawm qhov nruab nrab axes ntawm cov yeeb nkab kawg, ib qho tseem ceeb rau kev sib dhos qhov chaw.
Dimensional Tolerances thiab Application Considerations
Tolerance Requirements:Tus qauv ASME B16.9 qhia meej txog kev ua siab ntev rau txhua qhov ntev ntawm lub vojvoog ntev rov qab khoov. Piv txwv li, qhov kam rau ua rau qhov chaw nruab nrab - mus rau - qhov kawg nrug thiab qhov nruab nrab - mus rau - nruab nrab qhov nrug yuav tsum tau hais txog hauv nplooj 6-2 ntawm tus qauv. Kev tsim khoom tiag tiag thiab kev lees paub yuav tsum xyuas kom meej tias qhov ntev yog nyob rau hauv qhov tso cai sib txawv los lav kev sib txuas sib txuas.
Phab ntsa Thickness Matching:Phab ntsa thickness chav kawm ntawm qhov rov qab khoov yuav tsum phim cov yeeb nkab txuas (xws li Sch40, Sch80). Cov chav kawm sib txawv ntawm phab ntsa tuab tsuas yog cuam tshuam rau lub siab muaj peev xwm thiab qhov hnyav ntawm qhov haum, tsis yog qhov tseem ceeb ntawm qhov ntsuas.
Siv tau tshaj:Lub vojvoog ntev rov qab khoov yuav tsum tau siv nrog cov kav dej, flanges, li qub, thiab lwm yam khoom siv uas ua raws li ASME B16 series cov qauv kom ntseeg tau tias kev ua raws cai thiab kev nyab xeeb ntawm tag nrho cov kav dej.
Dimensional Verification:Ua ntej kev yuav khoom thiab kev teeb tsa, cov ntaub ntawv cim ntawm cov yeeb nkab haum (xws li cov lus qhia tshwj xeeb, tus lej xov tooj, cov khoom siv, thiab lwm yam) yuav tsum tau kuaj xyuas, thiab qhov tseem ceeb yuav tsum tau txheeb xyuas los ntawm kev ntsuas qhov tseeb kom tsis txhob teeb tsa tsis ua haujlwm vim qhov sib txawv ntawm qhov sib txawv.
