Ib qho API 5L X46 LSAW steel yeeb nkab submerged arc welded (lsaw) cov yeeb nkab uas ua tau raws li cov neeg siv hluav taws xob tshwj xeeb. Lub "X46" txhais tau tias tsawg zog muaj zog ntawm 46,000 psi (kilopound rau ib square ntiv taw tsim rau kev thauj cov roj, roj, thiab dej.
Cov yam ntxwv tseem ceeb
API 5L Txuj Ci:
Cov yeeb nkab ua kom zoo rau cov kev xav tau ntawm API cov kev xav tau ntawm API cov qauv 5L, uas teeb tsa cov qauv rau pipeline qhov ntev, cov khoom siv txhua yam, thiab cov tshuaj lom neeg.
Qib X46:
Tus "X" qhia txog qhov siab - Lub zog hlau qib, thiab "46" qhia nws qhov tsawg kawg nkaus tau lees lub zog.
LSAW kev:
Cov yeeb nkab yog tsim kev siv cov khoom siv ntev ntev arc vuam
Khoom siv:
Nws yog tsim los ntawm carbon hlau, uas muaj cov khoom zoo thiab hardness thaj chaw haum rau cov ntawv thov xav tau.
Cov Ntawv Thov
Tsheb thauj mus los ntawm dej:
Cov kav dej no tau siv dav hauv cov tshuab raj rau kev thauj mus los ntawm cov roj, roj, thiab dej nyob rau hauv ob qho chaw nyob rau sab nrauv thiab ntug dej.
Petrochemical Kev Lag Luam:
Cov yeeb nkab lub zog, durability, thiab weldable zog ua rau nws xaiv qhov kev xaiv ntawm petrochemical rau kev thauj ntau yam kua.
Qeb Khoom Qhia Tshwj Xeeb (PSL)
PSL1:
Tus qauv - zoo kab yeeb nkab uas ua tau raws li cov kev xav tau ntawm API 5L specification.
PSL2:
Ib qho siab dua - zoo kab yeeb nkab, cov khoom siv mechanies, thiab ntsuas qhov tsis muaj zog thiab kev ntseeg tau.
