Calibreflangetiaj welding flange thiab pob tw weld xaus yog li cov flange threaded flange tsis yog nyob rau hauv qhov tseeb ntau lawm thiab muag ntawm txoj kab uas hla loj, los yog ntau npaum li cas welding khoom accounted rau cov feem ntawm ca vuam ntawm loj txoj kab uas hla flange thiab taub qab vuam ntawm loj txoj kab uas hla flange qauv. thiab kev siv ntau yam sib txawv, tuaj yeem qhia cov yam ntxwv thiab qhov zoo ntawm kuj yuav txawv, yog li thaum siv yuav tsum tau siv raws li qhov sib txawv, los xyuas kom meej lub flange ua si lub luag hauj lwm tseem ceeb ntawm loj-inch ca vuam flange nrog tsis zoo rigidity, haum rau lub sijhawm siab p 4 mpa; Lub taub qab vuam flange, tseem hu ua siab caj dab flange, nruj, haum rau lub sijhawm kub siab.
Muaj peb hom flange sealing nto: dav hlau sealing nto, haum rau lub sijhawm tsis muaj tshuaj lom ntawm nruab nrab nrog lub siab tsis tshua muaj siab; Concave thiab convex sealing nto, haum rau lub sijhawm siab me ntsis; Mortise sealing nto, haum rau lub ntees ntawm inflammable thiab explosive. toxic nruab nrab thiab siab siab, loj txoj kab uas hla flange collocation nrog fasteners siv nyob rau hauv daim ntawv thov, cov nram qab no hais tias daim ntawv thov ntawm ob yam ntxwv: thawj yog lub mechanical zog ntawm loj txoj kab uas hla flange style yuav tsum nyob rau hauv lub dov kev taw qhia tom qab tshav kub kev kho mob ntawm lub blanks ntawm nyiag. , yog li txiav tawm txoj haujlwm yog: yog tias qhov khoob tsis ntau tshaj 40 hli txoj kab uas hla, ces yuav tsum muaj nyob rau hauv nruab nrab ntawm sampling; Yog hais tias txoj kab uas hla ntawm qhov dawb paug yog ntau tshaj 40 hli, ces lub equilong ob-lub taub hau stud thiab tag nrho cov xov. stud sampled nyob rau hauv nruab nrab ntawm ib tug peb lub hlis twg ntawm txoj kab uas hla yuav tsum tau sim nyob rau hauv batch thiab cov txiv ntseej yuav tsum tau sim nyob rau hauv batch rau hardness; cov raw khoom siv rau tshwj xeeb fasteners yuav tsum muaj cov khoom tsim nyog daim ntawv pov thawj ntawm cov chaw tsim tshuaj paus.

Flange yog fasteners rau fasteners thiab dav daim ntawv thov ntawm cov neeg kho tshuab qhov chaw yog dav siv tag nrho cov hom ntawm mechanical khoom tsheb instrumentation nkoj qauv ntawm railway choj siv cov cuab yeej thiab cov khoom siv xws li saum toj no, koj tuaj yeem pom txhua yam fasteners, nws yog cov yam ntxwv ntawm ntau yam specification yog ntau yam, kev ua tau zoo sib txawv, thiab cov txheej txheem ntawm generalizing loj txoj kab uas hla flange hom degree kuj yog tshwj xeeb fasteners, yuav tsum tau raws li tus naj npawb ntawm kev soj ntsuam tom qab tshav kub kev kho mob, soj ntsuam cov txiaj ntsig yuav tsum ua raws li cov kev cai, thiab yuav tsum xyuas kom meej tias lub Txhua yam khoom ntawm cov khoom tsis yog qis dua qhov kev ua tau zoo ntawm cov qauv ntsuas txhua qhov siv rau qhov loj-inch flanges nrog nominal siab PN tsis pub tsawg tshaj 10.0MPa yuav tsum tau tshuaj xyuas los ntawm cov khoom sib nqus raws li kev tshuaj xyuas tsis zoo ntawm JB 4730-1994 siab cov hlab ntsha ib leeg ib leeg.Tom qab kev tshuaj xyuas, yuav tsis muaj teeb meem nrog cov khoom, thiab nws yuav tsum ua kom tau raws li qhov yuav tsum tau muaj ntawm qhov loj-inch flanges ntawm theem nrab forgings.
