316 SS yeeb nkab fittings yog dab tsi?
316 stainless hlau yeeb nkab fittings xa mus rau cov yeeb nkab txuas cov khoom ua los ntawm 316 stainless hlau (los yog nws ultra- qis carbon version, 316L). Lawv tau siv dav hauv kev lag luam tsheb thauj mus los rau kev ua haujlwm xws li kev sib txuas, kev hloov pauv, txoj kab uas hla hloov, sealing, lossis kaw.
Hom Hom: Xws li lub luj tshib, tees, reducers, couplings, caps, thiab unions.
Cov Qauv: Ua raws li ASTM A403, ASME B16.9, thiab B16.11.
Daim ntaub ntawv: Dav siv nyob rau hauv tshuaj ua, offshore platforms, desalination nroj tsuag, zaub mov & dej haus, thiab kws industries.

Dab tsi yog qhov txawv ntawm 304 thiab 316 stainless hlau fittings?
Qhov sib txawv tseem ceeb ntawm 304 thiab 316 stainless hlau yeeb nkab fittings yog 316 muaj 2-3% molybdenum, muab nws superior corrosion kuj piv rau 304, tshwj xeeb tshaj yog nyob rau hauv chloride thiab marine ib puag ncig . 304 yog haum rau dav siv, sab hauv tsev, thiab dej tshiab daim ntaub ntawv, thaum 316, vim nws cov durability ntau dua, yog zoo dua nyob rau hauv cov tshuaj chemical thiab ntsev.
