Seamless Kev Tsim Kho: ASTM A335 P9 cov kav dej yog tsim los siv cov txheej txheem seamless, kom ntseeg tau tias muaj kev sib xyaw ua ke thiab cov qauv thoob plaws hauv cov yeeb nkab. Seamless kav dej muaj nyob rau hauv ntau qhov ntev thiab tuaj yeem tsim kho kom haum rau qhov project tshwj xeeb.

Kev kho cua sov:

Normalizing ntawm qhov kub thiab txias ntawm 1040 degree mus rau 1080 degree, ua raws li cua txias.

quenching thiab tempering ntawm qhov kub ntawm 760 degree mus rau 802 degree, ua raws li cua txias.

Daim ntawv thov:

Fais fab nroj tsuag: ASTM A335 P9 cov kav dej tau siv dav hauv cov chaw tsim hluav taws xob rau cov ntawv thov xws li cov kav dej, cov kav dej boiler, thiab superheaters.

Kev lag luam Petrochemical: Lawv yog siv rau hauv petrochemical refineries rau kev ua cov kua dej kub thiab cov pa roj.

Roj & Roj Kev Lag Luam: Cov ntawv thov suav nrog cov kav dej rau kev thauj cov kua dej corrosive thiab cov tshuab hluav taws xob siab siab.

Ua raws:

ASTM A335 P9 cov kav dej ua tau raws li ASTM A335 / ASME SA335 cov lus qhia tshwj xeeb, ua kom muaj kev ua raws li cov qauv kev lag luam rau seamless ferritic alloy steel kav siv hauv kev pabcuam kub.

Common Sizes thiab Specifications:

Sab nraud txoj kab uas hla (OD): 1/8 "NB rau 24" NB (Nominal Bore)

Phab ntsa Thickness (WT): Teem caij 20 rau Teem caij XXS (Ntxiv Ntxiv Muaj Zog)

Length: Txheem ntev ntawm 6 meters lossis kev cai ntev raws li tus neeg yuav tsum tau ua.

Case Study:

Nyob rau hauv ib lub tshuab fais fab, ASTM A335 P9 kav tau siv rau kev tsim kho ntawm superheaters thiab reheaters hauv chav boiler. Cov kav dej no muab kev tiv thaiv zoo heev rau qhov kub thiab txias oxidation thiab corrosion, kom ntseeg tau tias kev ua haujlwm ntawm boiler nyob rau hauv kev xav tau.

Zuag qhia tag nrho, ASTM A335 P9 seamless ferritic alloy steel kav yog nyiam rau lawv cov superior kub-kub lub zog, corrosion kuj, thiab durability, ua rau lawv ib tug tsim nyog xaiv rau kev siv tseem ceeb nyob rau hauv ntau yam lag luam.
