Duplex & Super Duplex Hlau Flange

ASTM A182 Duplex & Super Duplex Steel Flanges yog cov khoom siv hauv cov kav dej txuas rau cov kav dej, li qub, thiab lwm yam khoom siv. Cov flanges no yog tsim raws li ASTM A182 specification, uas tsim cov qauv forged los yog dov alloy thiab stainless hlau yeeb nkab flanges, forged fittings, thiab li qub thiab qhov chaw rau high-temperature kev pab cuam.

Duplex thiab Super Duplex stainless hlau yog hom stainless hlau alloys paub rau lawv zoo heev corrosion kuj thiab siab zog. Duplex stainless hlau, xws li UNS S31803 thiab S32205, muaj kev sib xyaw ua ke ntawm austenitic thiab ferritic microstructures, muab qhov sib npaug ntawm cov khoom tsim nyog rau ntau yam kev siv. Super Duplex stainless hlau, xws li UNS S32750 thiab S32760, muab cov qib siab dua ntawm kev tiv thaiv corrosion thiab lub zog, ua rau lawv haum rau ntau qhov chaw xav tau.

ASTM A182 Duplex & Super Duplex Steel Flanges muaj nyob rau hauv ntau hom, xws li slip-on flanges, weld caj dab flanges, dig muag flanges, ncej puab flanges, qhov (socket weld flanges), threaded flanges, thiab lwm yam. Lawv tau siv hauv kev lag luam xws li roj thiab roj, kev ua tshuaj lom neeg, petrochemical, marine, thiab offshore engineering, qhov uas tiv thaiv corrosion thiab siab zog yog qhov tseem ceeb.

Cov flanges no yog tsim los rau cov khoom siv tshwj xeeb, qhov ntau thiab tsawg, thiab kev ntsuas siab raws li tus qauv ASTM A182, kom ntseeg tau tias lawv ua tau raws li qhov tsim nyog thiab kev ua tau zoo rau lawv cov ntawv thov.

Application Scenario:

- Petroleum thiab Natural Gas Kev Lag Luam

- Tshuaj ua thiab cia

- Offshore Engineering

- Cov ntawv thov kev lag luam hauv Acid Environments

- Cov kab hluav taws xob xa hluav taws xob nyob rau hauv qhov kub thiab txias thiab siab-siab

Cov Teeb Meem Feem Ntau thiab Cov Txheej Txheem Kev Siv:

Qhov teeb meem: Leakage ntawm flange kev twb kev txuas.

Cov lus qhia:

- Xyuas kom cov flange nto yog du thiab tsis muaj qhov tsis xws luag.

- Siv lub flange sealing gasket kom raug.

- Tighten bolts raws li qhov xav tau torque.

Qhov teeb meem: Corrosion ntawm flange kev twb kev txuas.

Cov lus qhia:

- Xaiv cov khoom siv Duplex lossis Super Duplex uas tsim nyog corrosion kuj.

- Tsis txhob ncua ntev ntawm qhov nruab nrab.

- Tsis tu ncua tshuaj xyuas thiab tswj xyuas, tshem tawm cov khoom corrosion tam sim ntawd.
