1. Lub hom phiaj
Txhawm rau ntxiv dag zog rau kev tshuaj xyuas thiab kev tswj hwm ntawm flange forgings, tswj qhov zoo ua ntej cov khoom siv, thiab txo qhov poob ntau li ntau tau, cov kev cai no tau tsim tshwj xeeb. Raws li flange forgings, ntxiv rau kev tsim, tsim khoom, tshuaj xyuas thiab cov qauv ntsuas tau teev tseg hauv daim ntawv cog lus technical accessories thiab daim ntawv cog lus, nws yuav tsum ua kom tau raws li qhov yuav tsum tau ua thiab ua lub hauv paus rau kev tshuaj xyuas tuaj. Yog tias muaj kev tsis sib haum xeeb ntawm cov khoom siv thev naus laus zis, kev tsim qauv, tsim khoom thiab kev sim cov qauv uas tau teev tseg hauv daim ntawv cog lus, thiab qhov yuav tsum tau ua, qhov kev xav tau siab dua yuav tsum tau ua.
2. Scope ntawm daim ntawv thov
Qhov kev xav tau no siv rau feem ntau siv flange forgings ntawm ntau yam tshwj xeeb.

4. Kev tshuaj xyuas yuav ua raws li cov qauv flange.
Xws li ASME B 16.5, HG / T 20615 thiab lwm yam kev xav tau, kev tshuaj xyuas qhov ntev thiab kev kuaj pom yuav ua tiav ib qho.
4.1 Dimension Inspection
|
1 |
Kev soj ntsuam ntsuas lub cuab yeej caliper, ncaj board kav, qhov tob caliper, daim kab xev ntsuas |
|
2 |
Ntsuas qhov loj me hauv qab no nrog lub caliper, tus pas ntsuas, lossis daim kab xev ntsuas: Sab hauv txoj kab uas hla, sab nraud txoj kab uas hla, thickness, txheej txheej ntawm sealing nto, flange caj dab, txheej txoj kab uas hla ntawm caj dab kawg, ntsia liaj qhov rooj qhov nruab nrab lub voj voog txoj kab uas hla, ntsia liaj qhov rooj qhov sib nrug, ntsia liaj qhov rooj qhov taub. |
|
3 |
Muab lub flange tso rau ntawm lub platform thiab ntsuas qhov siab ntawm flange nrog rau qhov tob caliper |
|
4 |
Kev tshuaj xyuas ntawm flange puab txoj kab uas hla mus rau eccentricity ntawm qhov chaw nruab nrab ntawm lub qhov ntsia hlau qhov thiab qhov nruab nrab ntawm lub sealing nto: 4.1 Muab lub flange rau ntawm lub platform, thiab ntsuas qhov kev ncua deb ntawm qhov sib thooj bolt qhov thiab sab hauv phab ntsa ntawm flange nrog lub caliper, thiab qhov siab tshaj plaws ntawm qhov sib txawv yog qhov eccentricity; 4.2 Muab lub flange rau ntawm lub platform, ntsuas qhov sib thooj ntawm qhov sib khi nto nrog lub caliper, thiab qhov siab tshaj plaws ntawm qhov sib txawv yog qhov eccentricity. |
|
5 |
Rau cov flanges uas tsis yog tus qauv xws li LWN hom thiab forged qhov chaw, qhov ntev yuav tsum tau kuaj xyuas ib qho los ntawm ib qho raws li kev ua haujlwm sab nraud |
