ASTM A249 904L Tube Supplier, chaw tsim tshuaj paus
GNEE, ua ib lub chaw tsim khoom thiab chaw muag khoom ntawm stainless hlau welded kav, muaj tshaj 18 xyoo ntawm kev lag luam kev lag luam. Peb cov khoom nruj me ntsis ua raws li cov qauv thoob ntiaj teb xws li ASTM, EN, JIS, thiab GB, thiab tau lees paub los ntawm cov txheej txheem tso cai suav nrog ISO 9001 Kev Tswj Xyuas Zoo thiab PED 2014/68 / EU. Peb tau cog lus rau kev xa khoom sai thiab txhim khu kev qha: cov qauv kev txiav txim siab tau xa tuaj tsis pub dhau 7-15 hnub ua haujlwm, thaum kev tsim khoom tsim tau tiav hauv 20-30 hnub. Rau cov phiaj xwm ceev, peb muab qhov tseem ceeb ceev ceev - kev pabcuam taug qab los txhawb koj lub sijhawm ua haujlwm.
904L stainless hlau welded kav yog tsim los ntawm EAF-LF-VD refined steel coils, kom ntseeg tau tias ultra- cov ntsiab lus carbon tsawg (tsawg dua los yog sib npaug rau 0.02%), cov alloy muaj pes tsawg leeg (Cr 19.0–23.0%, Ni 23.0–28.0%), Mo. kev suav nrog tsawg tsawg.
ASTM A249 TP904L stainless hlau kav yog tsim los siv siab - zaus induction welding thiab nruam txoj kev siv tshuab, kom ntseeg tau tag nrho weld nkag mus thiab uniform microstructure. Txhua cov yeeb nkab tau txais cov tshuaj annealing ntawm 1050℃tom qab los ntawm kev ua kom txias sai kom rov qab ua kom corrosion thiab tshem tawm cov kev ntxhov siab welding.
Peb 904L ERW welded kav muaj ib tug PREN tus nqi Ntau dua los yog sib npaug rau 35, muab kev ua tau zoo heev rau pitting thiab crevice corrosion piv rau 316L welded kav. Mechanical zog muaj xws li tensile zog Ntau dua los yog sib npaug rau 515 MPa, yield zog Ntau tshaj los yog sib npaug rau 205 MPa, thiab elongation Ntau tshaj los yog sib npaug rau 35%.
Qhov muaj qhov loj me yog npog sab nraud ntawm 12.7-127 hli thiab phab ntsa tuab ntawm 0.4-8.1 hli. Sab nraud txoj kab uas hla yog nruj me ntsis tswj nyob rau hauv ± 0.005-0.015 ntiv tes, thiab phab ntsa thickness kam rau ua nyob rau hauv ± 10%. Txhua cov yeeb nkab tau dhau 100% hydrostatic testing, eddy tam sim no kuaj (ASTM E426), flattening test, flaring test, thiab rov khoov xeem los xyuas kom meej weld kev ncaj ncees. Tag nrho cov khoom tau muab nrog EN 10204 3.1 ntawv pov thawj.
