ASTM A312 TP304L Stainless hlau muaj yeeb nkab

Puas yog koj tab tom nrhiav kev lag luam piping uas ua raws li ASTM A312 cov qauv, muaj kev tiv thaiv corrosion zoo dua thiab kev ua haujlwm txhim khu kev qha, thaum tib lub sijhawm daws cov teeb meem cuam tshuam nrog vuam thiab qhov ntev precision?

Peb ASTM A312 TP304L stainless hlau muaj piping nta muaj cov pa roj carbon tsawg (tsawg dua los yog sib npaug rau 0.03%, ua raws li UNS S30403), zoo tiv thaiv intergranular corrosion tom qab vuam. Peb muab ob txoj kev xaiv: seamless kav thiab welded kav. TP304L seamless kav, tsis muaj weld seams, xyuas kom meej tag nrho lub zog nyob rau hauv siab -siab industrial puag ncig; conversely, TP304L welded kav dej muaj nqi tshwj xeeb -effectiveness, ua rau lawv haum rau ntau yam ntawm dav dav - hom phiaj daim ntawv thov. Ob qho kev hloov pauv tau ua raws li ASTM A312 thiab ANSI B36.19M tus qauv. Tag nrho cov kav dej tau muab tshuaj annealing ntawm qhov kub ntawm 1040℃txog 1100 degree; Cov txheej txheem no tshem tawm tag nrho cov kev ntxhov siab sab hauv thiab ua kom cov khoom siv tsis sib xws, yog li lav kev ua haujlwm ruaj khov thoob plaws qhov kub ntawm -200℃txog 870 degree.

Hais txog qhov ntev thiab qhov tseeb, peb siv cov kev tswj xyuas kom zoo: sab nraud txoj kab uas hla tolerances nyob rau hauv ± 0.02-0.4mm, phab ntsa thickness kam rau ua nyob rau hauv ± 10%, ncaj yog khaws cia kom tsawg tshaj li los yog sib npaug zos rau 0.5mm / m, thiab ntev tolerances tsis pub tshaj +10mm{5} kev sib sau ua ke ntawm high-precision 6.

ASTM A312 TP304L Stainless Hlau Yeeb Nkab rau cov nroj tsuag tshuaj

Peb tau ua tiav qhov kev sib tw tseem ceeb uas tau ntsib los ntawm cov nroj tsuag tshuaj: lub chaw ua haujlwm yav dhau los tau siv tus qauv 304 welded kav, tab sis cov no raug kev txom nyem los ntawm intergranular corrosion tom qab tsuas yog yim lub hlis ntawm kev ua haujlwm, yuam kom kaw cov kab ntau lawm. Tom qab hloov mus rau peb ASTMA312 TP304L seamless kav(cov lus qhia tshwj xeeb: Φ325 × 12mm), kev pabcuam lub neej ntawm cov kav dej tau txuas ntxiv mus rau 48 lub hlis- tsis yog tsuas yog txo tus nqi txij nkawm los ntawm 72% tab sis kuj tshem tawm tag nrho cov kev pheej hmoo ntawm kev xau yav tom ntej.

Tag nrho peb cov khoom raug kuaj 100% PMI (Positive Material Identification) thiab raug soj ntsuam ywj pheej los ntawm kev tso cai thib peb -cov koom haum xws li SGS. Nrog lub zog tensile ntawm Ntau dua lossis sib npaug ntawm 485 MPa, lub zog tawm los ntawm ntau dua lossis sib npaug ntawm 170 MPa, thiab elongation ntawm Ntau dua lossis sib npaug li 35%, peb cov khoom ua kom muaj tseeb thiab kev ntseeg siab ntawm tag nrho cov ntaub ntawv xeem, thaum ua raws li cov qauv kev lag luam thoob ntiaj teb.
