ASTM A335 Qib P22 Alloy Steel Yeeb Rau Boiler thiab superheater

Dab tsi yog ASTM A335?

ASME SA335 / ASTM A335, chrome - moly ferritic alloy {} Cov yeeb nkab sib xyaw ua ke rau cov kev pabcuam kub. Cov yeeb nkab xaj rau qhov kev cai tshwj xeeb no yuav tsum tsim nyog rau kev khoov, flanging, zoo ib yam kev ua haujlwm thiab rau kev sib tw ua ke vuam.

 

P22 cov khoom siv yog dab tsi?

A335 / sa335 Qib P22 Alloy Steel Seamless kav yog cov roj carbon steel pipes nrog ntxiv ntawm chromium, molybdenum, thiab qee zaum vanadium. Chromium, lossis chrome, txhim kho siab- kub lub zog, nce oxidation ua kom zoo thiab seb puas thiab hardness hauv chav sov.

Daim ntawv thov Astm A335 P22

1.Txhua siv tiam: Nws yog dav siv nyob rau hauv cov nroj tsuag fais fab rau kev tsim cov boiles boiles, chav head, thiab trave supereater / mam li rov qab. Lub Alloy Steel sib xyaw ntawm P22 tau muab qhov tseem ceeb tshaj plaws rau cov kub thiab xeb, ua rau nws haum rau cov khoom tseem ceeb no.

2. Tsis txhob siv cov A335 P225 P225 P225 P225 P225 P225 P222 yog siv rau kev tsim kho cov kav dej thiab cov fittings rau cov roj thiab roj ua kom dawb. Nws yog tshwj xeeb tsim los tiv thaiv cov roj av ua kom zoo nkauj, suav nrog kev kub siab, thiab cov ntawv thov siab.

3. Dememical Ua: P22 Alloy Steel Kave yog siv rau hauv cov nroj tsuag ua noj rau ntau yam kev siv, suav nrog cov tshuaj ua kua thiab raug cov cua sov. Nws txoj kev tawm tsam rau oxidation thiab corrosion ua rau nws haum rau kev tuav ntau cov tshuaj lom neeg.

4.Petrochemical kev lag luam: P22 kav nrhiav cov kev lag luam petrochemical dav rau kev thauj khoom ntawm cov tshuaj lom neeg, roj av, thiab hydrocarbons ntawm qhov kub thiab kub. Lawv feem ntau ua haujlwm hauv kev tsim kho cov hlab ntsha ua kom sov, kev hloov pauv kub, thiab lwm yam khoom tseem ceeb.
