Alloy 317L boiler tubing yog ib hom stainless hlau tubing tsim raws li tus qauv ASTM A213.ASTM A213 UNS S31703 Boiler Tubingyog tsim tshwj xeeb rau kev siv hauv boiler systems thiab tshav kub exchangers, qhov uas tsis kam mus rau kub kub thiab corrosive ib puag ncig yog qhov tseem ceeb. Txhim kho molybdenum cov ntsiab lus muab superior tiv thaiv corrosion piv rau lwm yam austenitic stainless hlau zoo li 316L. Lub 'L' nyob rau hauv 317L qhia txog cov ntsiab lus ntawm cov pa roj carbon tsawg, uas txhim kho nws cov kev tiv thaiv rau rhiab heev thaum vuam thiab ua kom zoo corrosion kuj nyob rau hauv raws li welded lug.

ASTM A213 Cov Qauv thiab Cov Qauv
ASME SA213 yog thawj tus qauv tswj kev tsim khoom ntawm 317L boiler tubing. Qhov kev qhia tshwj xeeb no ua kom cov tubing ua tau raws li qhov yuav tsum tau ua rau cov khoom siv kho tshuab, tshuaj lom neeg muaj pes tsawg leeg, thiab qhov tseeb qhov tseeb. Cov ntsiab lus tseem ceeb suav nrog:
- Dimensional Tolerances: Cov kev ntsuas meej kom haum seamlessly rau hauv cov tshuab uas twb muaj lawm.
- Mechanical Properties: Tsim nyog tensile thiab yield zog los tiv thaiv kev ua haujlwm siab.
- Surface Finish: Smooth nto kom txo qis qhov chaw pib qhov chaw.
