Astm A105
Qhov kev qhia tshwj xeeb no suav nrog cov qauv rau forged carbon steel piping Cheebtsam, uas yog, flanges, fittings, li qub, thiab cov khoom zoo sib xws, siv rau hauv cov tshuab siab ntawm ambient thiab siab dua cov kev pabcuam. Cov ntaub ntawv yuav tsum raug kho kom sov (annealing, normalizing, tempering, lossis quenching). Cov khoom yuav tsum ua raws li carbon, manganese, phosphorus, sulfur, silicon, tooj liab, nickel, chromium, molybdenum thiab vanadium cov ntsiab lus. Cov forgings yuav tsum raug rau qhov nro, hardness thiab hydrostatic xeem, nrog rau qhov kawg siv tau thaum xav tau. Cov khoom yuav tsum ua raws li lub zog tensile, tawm los lub zog, elongation, txo qhov chaw, thiab hardness yuav tsum tau.

Kev Ua Raws Cai
ASTM A105 forgings yuav tsum ua raws li cov lus qhia hauv ASTM A105 / A105M Standard Specification rau Carbon Steel Forgings rau Piping Applications. Tsis tas li ntawd, lawv yuav tsum tau ua kom tau raws li lwm cov qauv kev lag luam thiab cov kev qhia tshwj xeeb, xws li ASME B16.5, ASME B16.11, ASME B16.34, thiab API 6A, nyob ntawm daim ntawv thov thiab kev npaj siv.
Kev tsim khoom
ASTM A105 forgings feem ntau yog tsim los ntawm cov txheej txheem kub forging lossis kev kho cua sov, ua raws li kev ua haujlwm kom ua tiav qhov ntev thiab qhov chaw tiav. Cov txheej txheem tsim khoom yog tswj hwm los ntawm ASTM A105 / A105M Txuj Kev Qhia Tshwj Xeeb rau Carbon Steel Forgings rau Piping Applications.
Daim ntawv thov
ASTM A105 forgings tau siv dav hauv ntau qhov kev lag luam, suav nrog roj thiab roj, petrochemical, tshuaj ua haujlwm, tsim hluav taws xob, kho dej, thiab kev tsim kho. Lawv feem ntau yog siv los tsim cov flanges, fittings, li qub, thiab lwm yam piping Cheebtsam rau high-pressure thiab high-temperature daim ntaub ntawv.
