Cov teeb meem uas xav tau kev saib xyuas thaum stainless hlau flanges

1. Txhawm rau tiv thaiv kev cuam tshuam ntawm lub qhov muag los ntawm cov cua sov ntawm lub flange npog, qhov vuam tam sim no yuav tsum tsis txhob loj dhau, li ntawm 20 feem pua ​​​​tsawg dua cov pa roj carbon steel electrode, lub arc yuav tsum tsis txhob ntev dhau, lub interlayer txias. yuav tsum ceev ceev, thiab nqaim weld hlaws yuav tsum haum.

2. Thaum siv electrodes, cia lawv qhuav. Ti-Ca hom yuav tsum tau qhuav ntawm 150 degree rau 1 teev, low-A hom hydrogen yuav tsum tau qhuav ntawm 200-250 degree rau 1 teev (cov txheej tsis tuaj yeem qhuav dua, txwv tsis pub nws yooj yim tawg thiab tev tawm. ) txhawm rau tiv thaiv cov electrode txheej Cov roj nplaum thiab lwm yam av kom tsis txhob ua kom cov pa roj carbon ntau ntawm cov vuam thiab cuam tshuam rau qhov zoo ntawm cov vuam.

3. Thaum lub sij hawm vuam txheej txheem ntawm stainless hlau flange kav, carbides yuav precipitated vim rov ua cua sov, uas txo corrosion kuj thiab txhua yam khoom.

Flat sealing nto, haum rau lub sijhawm uas tsis tshua muaj siab thiab tsis muaj kuab lom; Concave-convex sealing nto, haum rau lub sijhawm nrog me ntsis siab dua; tus nplaig thiab zawj sealing nto, haum rau cov nplaim taws, tawg, muaj kuab lom thiab lub sijhawm siab. Loj-inch flanges feem ntau yog siv ua ke nrog fasteners hauv daim ntawv thov. Cov yam ntxwv ntawm daim ntawv thov ntawm ob yog piav qhia hauv qab no: Ua ntej, cov khoom siv ntawm qhov loj-inch flanges yuav tsum raug nyiag los ntawm cov cua sov-kho dawb paug raws li cov kev taw qhia dov thiab txiav tawm nyob rau hauv txoj hauj lwm yog: yog hais tias txoj kab uas hla ntawm qhov dawb paug yog. tsis ntau tshaj 40mm, ces sampling ntawm qhov chaw; Yog tias txoj kab uas hla ntawm qhov khoob yog ntau dua 40mm, ces ua piv txwv ntawm qhov nruab nrab ntawm ib feem peb ntawm txoj kab uas hla. Qhov sib npaug-ntev ob-kawg studs thiab tag nrho cov xov studs yuav tsum raug rau cov kev xeem ua haujlwm hauv cov khoom siv. Cov txiv ntseej yuav tsum tau kuaj xyuas qhov hardness hauv cov khoom siv; cov ntaub ntawv raw rau cov fasteners tshwj xeeb yuav tsum muaj daim ntawv pov thawj ntawm cov khoom tsim nyog.
