ASTM A268 TP409 Ferritic Stainless Hlau Tube

ASTM A268 TP409 stainless hlau seamless yeeb nkab yog ferritic stainless hlau yeeb nkab nrog corrosion kuj zoo heev thiab siab -kub kev ua tau zoo, haum rau corrosive ib puag ncig nyob rau hauv cov tshuaj, roj av, thiab natural gas industries.

​

​GNEE cov khoom siv siab- zoo TP409 stainless hlau round kav, ua raws li ASTM A268 tus qauv. Cov txheej txheem tsim khoom suav nrog kev tswj xyuas cov tshuaj lom neeg nruj, kev kho cua sov (qhov kub thiab txias ntau dua lossis sib npaug ntawm 1200℃F [650 degree]), thiab kev ntsuas cov cuab yeej cuab tam (xws li tensile zog ntawm 415-485 MPa). Cov kav dej no yog tsim los siv cov txheej txheem seamless (xws li extrusion lossis tho). Cov qauv seamless ua kom cov phab ntsa tuab tuab, seamless kev ncaj ncees (dawb los ntawm weld seams), thiab siab dua kev cia siab rau. Cov kav dej muaj nyob rau hauv ob qho tib si tov-annealed thiab kub-kho tej yam kev mob

​

Tsis tas li ntawd, tag nrho cov kav dej tau txais kev tshuaj xyuas zoo, suav nrog kev ntsuas hydrostatic nrog qhov tsawg kawg nkaus ntawm 5.5 MPa (800 psi) kom ntseeg tau tias kev sib khi ua tau zoo, nrog rau kev tshuaj xyuas qhov muag thiab kev ntsuam xyuas saum npoo av (Ra tsawg dua lossis sib npaug li 6.3 μm) kom lav qhov tsis muaj khawb, qhov pits, lossis khawb. Qhov no ua kom ntseeg tau qhov kev ua tau zoo hauv cov tshuab hluav taws xob hauv tsheb, cov khoom siv hluav taws xob, thiab cov kav dej ua lag luam. Email:info@gneestainless.com
