API 5L PSL1 X42 ERW Pipe Technical Overview
API 5L PSL1 X42 ERW (Electric Resistance Welded) yeeb nkab yog cov txheej txheem steel kab yeeb nkab tshwj xeeb dav siv hauv kev thauj mus los ntawm roj, roj, thiab lwm yam dej hauv kev lag luam hluav taws xob.
Basic Specifications
API 5L (American Petroleum Institute Specification 5L) npog seamless thiab welded steel kab yeeb nkab. Qhov kev xaiv "PSL1" yog hais txog Cov Khoom Qhia Tshwj Xeeb Qib 1, uas sawv cev rau cov qauv kev xav tau zoo. "X42" qhia qhov tsawg kawg nkaus lub zog ntawm 42,000 psi.
Cov yam ntxwv tseem ceeb ntawm ERW txheej txheem:
tsim: Hlau kauj yog tsim rau hauv cylindrical zoo
Vuam: Edges yog rhuab los ntawm hluav taws xob tsis kam thiab fused yam tsis muaj muab tub lim hlau
Qhov loj me: Cov yeeb nkab yog qhov loj me kom meej qhov ntev
Kev sim: Ntau yam uas tsis yog -kev ntsuam xyuas kev puas tsuaj kom ntseeg tau tias muaj kev ncaj ncees
