ASTM A312 thiab ASTM A269

ASTM A312 thiab ASTM A269: Kev qhia rau cov kav hlau stainless hlau **

ASTM A312 thiab ASTM A269 yog ob qho qauv ntawm Astm thoob plaws Astims cov khoom lag luam thoob dej cawv. Thaum lawv tau npog cov qhab nia zoo sib xws ntawm cov hlau tsis sib xws (xws li 304 / 314l thiab kev xaiv ntawm lawv cov kev tsim qauv sib txawv rau kev siv cov ntawv thov engineering.

** ASTM A312: Tus Qauv Tseeb rau Seamless, Welded, thiab hnyav txias ua haujlwm Austenitic Stainless Hlau Pipes **

Qhov kev qhia tshwj xeeb no yog thawj tus qauv rau cov kav hlau stainless hlau siv tau nyob rau hauv high {{} - sov daim ntawv thov, tshwj xeeb hauv kev lag luam kub. Cov kav dej ua raws li A312 feem ntau pom hauv:
* ** Cov nroj tsuag thiab petrochemical nroj tsuag: ** Rau kev thauj cov kua dej.
* ** COV ROJ THIAB TUA DUA: ** Hauv Kev Ua Si Piping thiab Pipelines.
* ** Lub zog loj: ** Tshwj xeeb tshaj yog nyob rau hauv cov raj boiles thiab siab - dej sov kab.
* ** PURP thiab cov ntawv MILLS: ** Rau kev tswj cov tshuaj corrosive.

A312 npog ntau qhov ntau thiab tsawg, los ntawm me- dexia txoj sia rau loj- txoj hauj lwm uas hla hla. Tus yam ntxwv tseem ceeb yog nws lub siab tsom rau ** siab -}} muaj cov ntawv thov **. Raws li xws li, cov kav dej no tau dhau helostatic lossis tsis - kev ntsuas hluav taws xob tiv thaiv lawv txoj kev ncaj ncees hauv siab. Cov txheej txheem tso cai ob qho tib si kev sib txuas thiab welded cov txheej txheem tsim tawm, nrog welded kav feem ntau yog ua haujlwm txias tom qab vuam kom muaj zog thiab tsim homogeneous qauv.

** ASTM A269: Txheem kev qhia tshwj xeeb rau kev sib khi thiab welded ustenitic stainless hlau tubing rau cov kev pab cuam dav hlau **

ASTM A269 yog qhov mus - rau cov qauv rau stainless hlau "tubing ** siv hauv kev txhawj xeeb ntawm kev txhawj xeeb thawj. Lo lus "tubing" feem ntau cuam tshuam siv nyob rau hauv cov ntawv thov tshuab, kev ua piv txwv, thiab kev sib pauv khoom siv thaum tshav kub. Cov ntawv thov raug muaj xws li:
* ** Kev hloov kho kom sov thiab cov hnab looj: ** Rau shells, leeg, thiab sab hauv.
* ** Cov kab thiab cov kab hydraulic: ** Txhawm rau thauj cov roj av lossis kua rau cov twj thiab sensors.
* ** Khoom noj khoom haus, dej haus, thiab kev ua tshuaj ua haujlwm: ** Qhov twg kev nyiam huv thiab kev ua kom haum thiab corrosion tsis yog qhov tseem ceeb.
* ** Cov ntawv thov architive thiab cov qauv lossis kua - nqa lub hom phiaj.

Tubing nyob rau hauv A269 feem ntau xaiv rau nws qhov ntev ntev kev tiv thaiv, zoo dua cov chaw ua tiav, thiab kev ntseeg tau nyob hauv cov chaw muaj teeb meem. Thaum nws tuaj yeem yog seamless, nws yog feem ntau muab khoom hauv welded thiab annealed mob. Cov kev xeem yuav tsum tau ua ntu zus rau kev ua kom corrosion tsis kam thiab lub suab es tsis muaj qhov siab.

Hauv cov ntsiab lus, kev xaiv ntawm Astm A312 thiab A269 Cov Pob Ntseg ntawm daim ntawv thov cov khoom siv: ** A212 yog xaiv rau high} Cov ntawv thov kub, thiab cov ntawv thov cua sov ** qhov twg cov ntaub ntawv cua sov ** qhov twg cov ntaub ntawv cua sov ** qhov twg cov ntaub ntawv cua sov ** qhov twg cov ntaub ntawv cua sov ** qhov twg qhov ntev dua yog qhov tseem ceeb.
