Peb unc undless steel wrd caj dab caj dab tuaj nyob rau ntau lub sij hawm ntawm cov kav dej ntawm cov kav dej uas muaj peev xwm pom tau vim nws lub hub tapered uas nws kis las.

Incoloy 925 Qhov muag tsis pom Rued Flanges sib xyaw ua ke ntawm kev siv lub zog ntawm Incoloy-Hangers, cov khoom plig, thiab tubulars rau sour roj ntau lawm.

Cheebtsam tsim ua nyob rau hauv cov lus qhia txog cov astm A182 xws li 317l stainless hlau flanges yog npaj los siv rau nce qhov kub. Qhov kev cai no yuav siv rau hauv cov kev xav tau ntau yam uas cov flanges yuav tsum ua raws li. Feem ntau, zoo ib yam li feem ntau cov astm specifications, cov ASTM A182 tau ua raws li ob qho tib si kev siv tshuab thiab cov kev ntsuas

304 \ / 304L Stainless Hlau Yeeb Nkab yog ib qho ntawm feem ntau dav siv stainless hlau qib. Nws muaj cov ntsiab lus roj carbon tsawg thiab cov roj chromium siab thiab npib tsib xee. Nws yog ib qho yooj yim los kos thiab daim ntawv, thiab ua kom pom lub zog zoo thiab kev tiv thaiv kev tiv thaiv zoo heev, suav nrog kev tiv thaiv kev xeb hauv lub sijhawm vuam.

? Tus? ASTM A182 F304 flanges? Yuav ntxuav tau yooj yim nrog ib qho tshuaj ntxuav me me. Txawm hais tias tau rov qab ua dua cov txheej txheem tu, cov flanges yeej¡-kawg, muaj peev xwm nws cov khoom pov thawj vim nws tau hnav cov khoom tiv thaiv nws. Ntxiv mus, txij li qib 304 yog ib qho alloy uas tuaj yeem tsim tau yooj yim rau hauv ib hom duab, nws yog qhov yooj yim shau rau hauv ib qho ntawm as44 yeeb nkab flange lossis ib qho? INOX 304 NPE rau Flange.

Ntxiv rau Nickel, cov alloy kuj muaj cov tooj liab loj. Tsis yog tsis yog tooj liab tsis yog ua cov s08904 cov ntsia hlau tiv phom thiab ntsev kuj tseem yuav txhim kho cov alloy cov leej faj tsis kam. Qhov kev sib ntxiv ntawm cov ntsiab lus tooj liab toppen hlau 904L hex bolts muab ntau dua li cov neeg siv nyiaj chromium ntau dua li cov roj ntsha, tshwj xeeb yog cov kua qaub, acetic thiab sulfuric acids.

304L stainless hlau yog ib qho ultra-tsawg cov pa roj carbon version ntawm 304 hlau alloy. Cov ntsiab lus hauv cov roj carbon qis hauv 304L minimizes tsis xav tau lossis tsis xav tau carbide nag lossis daus los ntawm vuam. Yog li ntawd, 304L tuaj yeem yog "welded" nyob rau hauv ib puag ncig corrosive loj thiab tsis tas yuav muaj annealing.
