Calibreflangetiaj welding flange thiab pob tw weld xaus yog li ntau flange threaded flange tsis yog nyob rau hauv qhov tseeb ntau lawm thiab muag ntawm loj txoj kab uas hla, los yog ntau npaum li cas welding khoom accounted rau cov feem ntawm lub tiaj welding ntawm loj txoj kab uas hla flange thiab pob tw welding ntawm loj txoj kab uas hla flange qauv thiab kev siv ntawm ntau yam yog txawv, muaj peev xwm qhia tau cov yam ntxwv thiab zoo ntawm kuj yuav tsum tau siv ntau yam los xyuas kom meej qhov tseem ceeb ntawm kev siv lub luag hauj lwm. loj-ntev ca vuam flange nrog tsis zoo rigidity, haum rau siab p 4 mpa zaus; Lub taub qab vuam flange, tseem hu ua siab caj dab flange, nruj, haum rau siab kub siab zaus.
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 lom 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 cov yam ntxwv ntawm cov khoom loj yuav tsum: Ua raws li cov kev taw qhia dov tom qab kev kho cua sov ntawm qhov khoob ntawm kev 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 coj mus kuaj ntawm qhov chaw ntawm ib tug peb lub hlis twg ntawm cov batches yuav tsum tau kuaj. hardness; Cov khoom siv raw siv rau cov fasteners tshwj xeeb yuav tsum muaj daim ntawv pov thawj khoom tsim nyog ntawm cov chaw tsim khoom.

Flange yog fasteners rau fasteners thiab dav daim ntawv thov ntawm cov neeg kho tshuab qhov chaw yog dav siv txhua yam ntawm txhua yam khoom siv 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 ntawm kev kho mob yuav tsum tau tshwj xeeb fasten tus naj npawb. Kev soj ntsuam cov txiaj ntsig yuav tsum ua raws li cov kev cai cuam tshuam ntawm, thiab yuav tsum xyuas kom meej tias cov khoom siv ntawm cov khoom tsis yog qis dua qhov 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 soj ntsuam tsis muaj kev puas tsuaj ntawm JB-1940. 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.
