Duplex UNS S31803 Information Information

Mwachidule

Duplex ndi austenitic ferritic Iron Chromium-Nickel alloy yokhala ndi Molybdenim kuwonjezera. Imakhala ndi kukana kwabwino kwa pitting, kulimba kwamphamvu kwambiri komanso kukana kwambiri kupsinjika kwa dzimbiri pakumatentha pang'ono poyerekeza ndi zitsulo zosapanga dzimbiri za austenitic wamba.

Duplex ndi chinthu chokhala ndi pafupifupi ofanana kuchuluka kwa austenite ndi ferrite. Izi zimaphatikiza kukana kwa dzimbiri kwabwino kwambiri ndi mphamvu yayikulu. Makina amakina ndi pafupifupi kuwirikiza kawiri kwa chitsulo chimodzi cha austenitic ndipo kukana kupsinjika kwa corrosion ndikwapamwamba kuposa mtundu wa 316 chitsulo chosapanga dzimbiri muzitsulo za chloride. Duplex zakuthupi zimakhala ndi kusintha kwa ductile / brittle pafupifupi -50 ° C. Kugwiritsa ntchito kutentha kwakukulu nthawi zambiri kumangokhala pa kutentha kwakukulu kwa 300 ° C kuti agwiritsidwe ntchito kosatha chifukwa cha ebrittlement.

Ubwino

Pali maubwino angapo a Duplex kuphatikiza:

Mphamvu Zapamwamba

High kukana pitting, mipata dzimbiri kukana

High kukana kupsinjika dzimbiri ang'onoang'ono, kutopa ndi kukokoloka

Kukana kwabwino kwa Chloride stress corrosion cracking

Kukula kwamafuta otsika komanso kutentha kwapamwamba kuposa zitsulo za Austenitic

Mayamwidwe amphamvu kwambiri

Zabwino ntchito ndi weldability

Mapulogalamu

Chitoliro - ASTM A790

Njira yopangira ikhoza kukhala yopanda msoko kapena yowotcherera yokha, popanda kuwonjezera zitsulo zodzaza. Chitoliro chikhoza kukhala chotentha kapena chozizira koma chiyenera kuperekedwa nthawi zonse pakatentha.

BUTT WELD - ASTM A815

Kalasiyi imaphatikizapo kalasi ya WP, yopangidwa ndi magulu a 4 ndikukwaniritsa zofunikira za ANSI B16.9. Kupanikizika kwa mavoti ndikofanana kofanana ndi chitoliro chofananira.

WP-W : Zomangamanga zowotcherera pomwe zowotcherera zomanga zimajambulidwa ndi radiograph

WP-WX : Zomangamanga zowotcherera pomwe ma weld onse amajambulidwa ndi radiograph

WP-WU : Zomangamanga zowotcherera komwe ma welds amayesedwa ndi Ultrasonically.

Flanges ASTM A182

Mafotokozedwe a ASTM amawongolera zida zovomerezeka zomwe ma flanges angapangidwe. Ma flanges achitsulo opangidwa ndi aloyi kapena ogubuduza, zopangira zopangira ndi ma valve opangira kutentha kwambiri.
