Dab tsi thicknesses muaj rau ASME SA612?
ASME SA612Lub siab lub nkoj steel phaj feem ntau muaj nyob rau hauv thicknesses txog li 1 nti (25 hli) raws li lub hauv paus specification. Thaum 25 mmyog tus qauv kev txwv, kev cai, kev tsim tshwj xeeb tso cai rau thicknesses li ntawm 6mm mus rau 150mm, nrog rau qee cov neeg muag khoom muab txog li 400 hli.
ASME SA612 yog "cov neeg ua haujlwm" cov khoom siv rau kev tsim cov hlab ntsha siab, tshwj xeeb rau kev fusion- vuam daim ntawv thov. Nws tau lees paub rau nws qhov siab manganese- rau- carbon piv, uas muab cov lus teb muaj zog rau kev kho cua sov thiab ua kom muaj kev sib koom ua ke tawv, tawv welded. Vim hais tias nws yog ib tug tua, nplua - steel hlau, nws coj kwv yees nyob rau hauv qhov kub siab ntawm arc vuam, tswj kev ncaj ncees ntawm tshav kub- cuam tshuam cheeb tsam (HAZ). Qhov no ua rau SA612 qhov kev xaiv zoo tshaj plaws rau cov neeg tsim khoom tsim siab - cov cuab yeej siv siab uas yuav tsum ua tau raws li cov qauv nruj thiab kev nyab xeeb ntawm ASME Boiler thiab Pressure Vessel Code.
