Astm A269 Tubing Specifications
HT PIPE yog ib qho ntawm cov khoom muaj npe zoo ASTM A269 Tubing Suppliers, yog cov khoom siv ntau yam thiab dav siv stainless hlau.ASTM A269 Stainless hlau rajmuab qhov zoo tshaj plaws tiv thaiv rau pitting thiab corrosion ntawm ib qho ntawm austenitic (300 series) stainless hlau. Nws yog ductile heev, nrog zoo heev lub zog ntawm elevated kub. Nws yog zoo tagnrho rau hydraulic thiab instrumentation tubing nyob rau hauv tshuaj, textile, thiab pulp thiab ntawv industries, thiab nyob rau hauv marine ib puag ncig.
ASTM A269 / A269M Txuj
ASTM A269 tubing yog rau kev pabcuam dav dav, feem ntau, nws yog siv rau hauv cov khoom siv thiab cov cuab yeej siv, thiab nyob rau hauv qis lossis siab - qhov kub thiab txias, yog li ntawd, ASME SA 269 tubing kuj tseem siv rau cov khoom siv hluav taws xob.
A269 Stainless Hlau Tubing Khoom thiab Qib
ASME SA269 tus qauvCov lus qhia tshwj xeeb qhia cov khoom siv raj yog Austenitic Stainless Steel qib, uas yog siv dav hauv cov tsev neeg hlau stainless, TP304, TP304L, TP316, TP316L, TP347, TP347H, TP321, TP321H, 904L qib yog cov khoom siv zoo rau ntau yam kev siv.
