Kev tsis

Stainless hlau pob tw weld fittings yog txhais raws li cov khoom siv hauv cov kav dej los hloov cov kev taw qhia, ceg, los yog hloov txoj kab uas hla ntawm cov yeeb nkab thiab yog mechanically txuas nrog lub system. Butt-weld fittings yog stainless hlau fittings nrog pob tw-weld sib txuas kom yooj yim installation thiab txij nkawm. Hom 304 stainless hlau yog cov khoom siv chromium-nickel uas tiv thaiv corrosion los ntawm dej, cua sov, brine, acids, minerals, thiab peaty av. Hom 316 stainless hlau muaj cov ntsiab lus nickel ntau dua li 304 stainless hlau, ntxiv rau molybdenum rau kev tiv thaiv corrosion ntau dua.

ASTM A403 yog tus qauv tshwj xeeb uas npog wrought stainless hlau fittings rau kev siv cov kav dej siab. Ntau qib ntawm austenitic. Ob peb qib ntawm austenitic stainless hlau alloys suav nrog hauv qhov kev qhia tshwj xeeb Cov Qib tau raug xaiv nrog ua ntej, WP lossis CR, raws li qhov siv tau ASME lossis MSS qhov ntev thiab cov qauv ntsuas, raws li.

Peb muab stainless hlau taub qab vuam fittings raws li ASME B16.9, EN10253-4/-3, nrog rau stainless hlau luj tshib, sib npaug / txo tees, conc / Ecc reducers, stainless hlau hau, stainless hlau luv xaus, thiab lwm yam Peb muab ntau yam ntawm SS pob tw weld fittings nyob rau hauv ntau yam stainless hlau qib 304, 304L, 316, 316L, 317, 317L, 321, 904L, thiab lwm yam.

Butt weld fittings yog txuas nrog cov kav dej rau kev thauj huab cua, dej, roj av, thiab roj rau kev siv cov kav dej, nrog rau kev ua zaub mov thiab khoom noj siv mis. Stainless hlau yeeb nkab fittings tiv thaiv corrosion los ntawm corrosive chemicals, corrosive kua, roj, thiab gases thiab muaj peev xwm tiv taus siab thiab kub. Hom 304 stainless hlau yog cov khoom siv chromium-nickel uas tiv thaiv corrosion los ntawm dej, cua sov, brine, acids, minerals, thiab peaty av. Hom 316 stainless hlau muaj cov ntsiab lus nickel ntau dua li 304 stainless hlau, ntxiv rau molybdenum rau kev tiv thaiv corrosion ntau dua.
