Duplex Steel Tube

Duplexstainless hlau yeeb nkab(seamless raj thiab welded raj) tuaj yeem muab faib ua plaub hom: qis alloy, nruab nrab alloy, siab alloy, thiab super duplex stainless hlau hom. Lub ntsiab yam ntxwv ntawm duplex stainless hlau raj yog tias nws lub zog tawm los tuaj yeem ncav cuag 400-55OMPa, uas yog ob npaug ntawm cov hlau tsis zoo tib yam, yog li nws tuaj yeem txuag cov ntaub ntawv thiab txo cov nqi tsim khoom. Nyob rau hauv cov nqe lus ntawm corrosion kuj, tshwj xeeb tshaj yog rau cov neeg pluag tej yam kev mob ntawm nruab nrab (xws li seawater thiab siab chloride ion cov ntsiab lus), tsis kam mus rau pitting, crevice corrosion, kev nyuaj siab corrosion, thiab corrosion qaug zog ntawm duplex stainless hlau yog ho zoo dua li cov zoo tib yam austenite. , zoo li high-alloy austenitic stainless hlau.

Specification ntawm Duplex Steel Tubes

Steel Qib:

Duplex 2507 (UNS S32750)yog super duplex stainless hlau nrog 25% chromium, 4% molybdenum, thiab 7% nickel tsim.

Duplex 2205 (UNS S31803), los yog Avesta Sheffield 2205 yog ferritic-austenitic stainless hlau.

Super Duplex UNS S32760- yog super duplex stainless hlau, thiaj li hu ua vim nws siab dua Chromium thiab Molybdenum cov ntsiab lus.
