TIAB SA 387GR11

ASTM (SA387GR11CL2) ASME A387GR22CL2 siv los tsim cov boilers thiab cov hlab ntsha siab. Cov hlau phaj rau cov hlab ntsha siab tuaj yeem tsim rau hauv cov cuab yeej uas yuav txhawb nqa qee qhov siab, kub thiab nruab nrab, yog li lawv yuav tsum muaj lub zog siab, zoo toughness, weldability thiab nto zoo. Ntau yam thiab qhov ntau thiab tsawg ntawm cov khoom yuav tsum tau xa tuaj rau hauv kev kho cua sov thiab ua kom tau raws li kev ntsuas ultrasonic. Cov hlau no tau siv dav hauv ntau qhov haujlwm hauv kev lag luam hauv tebchaws, xws li reactor, heat exchanger, separator, spherical tank, oil tank, LPG tank, boiler steam nruas thiab siab kav hauv machinery, roj av thiab tshuaj, hluav taws xob fais fab thiab metallurgy industries, thiab lwm yam. .
