cov khoom paub meej

Kev tsim cov 2205 thiab 2507 duplex stainless hlau vuam kav feem ntau suav nrog cov kauj ruam hauv qab no:

Raw khoom npaj

Xaiv 2205 lossis 2507 daim ntawv lossis sawb haum rau ASTM A790 / A789 lossis EN 10216-5 tus qauv.

Moulding

Cov txheej txheem ntawv los yog sawb rau hauv cov yeeb nkab zoo los ntawm txias dov lossis txias txheej txheem.

Vuam

Siv TIG (tungsten ncej argon arc vuam) los yog MIG (hlau inert gas tiv thaiv vuam). Cov txheej txheem vuam yuav tsum tau tswj nruj me ntsis thaum lub sij hawm vuam txheej txheem los xyuas kom meej qhov vuam zoo.

Kev kho cua sov

Tom qab vuam, cov khoom siv kho mob yuav tsum tau kho kom rov zoo dua corrosion thiab mechanical zog ntawm cov khoom.

Kev tshuaj xyuas thiab tshuaj xyuas

Ua kev kuaj tsis muaj kev puas tsuaj ntawm cov yeeb nkab welded, xws li kev kuaj ultrasonic, kuaj pom hluav taws xob, thiab lwm yam, kom ntseeg tau tias qhov vuam tsis muaj qhov tsis xws luag. Mechanical properties tests thiab corrosion resistance test yog ua ib txhij.

Kev kho saum npoo

Raws li qhov xav tau, cov welded yeeb nkab nto kho, xws li pickling, passivation, thiab lwm yam, los txhim kho corrosion kuj.

Ntim thiab xa khoom

Ntim tsim nyog welded kav kom tsis txhob muaj kev puas tsuaj thaum thauj.

2205 thiab 2507 ob-theem stainless hlau welded kav yog qhov zoo tagnrho rau ntau daim ntawv thov kev lag luam vim tias lawv cov tshuaj chloride corrosion kuj zoo heev. Thaum xaiv thiab siv cov ntaub ntawv no, xyuas kom meej tias cov qauv tsim nyog thiab cov kev qhia tshwj xeeb raug ua raws li kom ntseeg tau tias kev ua tau zoo thiab kev nyab xeeb ntawm cov ntaub ntawv.
