Dab tsi yog qhov sib txawv ntawm API 5L X80 thiab A179?
API 5L X80 thiab A179 yog ob qho qauv steel sib txawv steel, feem ntau yog nyob rau hauv cov chaw hauv qab no:
Chaw Thov:
API 5L X80 yog ib lub zog nyob rau hauv API cov yeeb nkab rau pipeline steel yeeb nkab, uas yog siv roj av thiab roj kev lag luam rau cov kab kis roj.
A179, ntawm qhov tod tes, yog tsuas yog siv hauv kev tsim cov khoom siv hluav taws xob, tshwj xeeb tshaj yog cov raj txias.
Lub zog thiab specifications:
X80 sawv cev yam tsawg kawg yog lees lub zog ntawm 80, {2}} psi (kwv yees li 552 mpa
Tus qauv A179 muaj cov txiaj ntsig ib lub zog ntau dua lossis muaj zog rau 185 MPA kom muaj zog ntau dua lossis muaj ntau yam kub rau kev siv hauv cov leeg boiles.
Txheej txheem tsim khoom:
Kev tsim khoom ntawm API 5L X80S yuav suav nrog cov txheej txheem tshwj xeeb, xws li kev kho mob tswj thiab ua kom muaj lub zog thiab tawv ntawm cov yeeb nkab.
Kev tsim khoom ntawm A179 yuav ua kom pom ntau dua ntawm thermal conductivity thiab corrosion tsis kam, thiab yog li ntawd yuav txawv ntawm X80 hauv cov khoom kev xaiv thiab kev tsim khoom.
