Lub ntsiab
API 5L (American Petroleum lub koom haum qhia tshwj xeeb 5L) yog tus qauv pom zoo rauKab YeebSiv rau hauv kev thauj mus los ntawm roj, dej, thiab roj hauv cov roj av thiab ntuj muaj kev lag luam.Pls1 (Theem Khoom Tshwj Xeeb Qib 1)yog ib qho ntawm peb cov khoom lag luam tshwj xeeb txhais tau nyob hauv API 5L, nrog PSL 1 sawv cev rautheem pib ntawm cov kev xav taurau cov kev siv hluav taws xob pipeline.
- PSL1: Qib qib no muab cov qauv ua haujlwm zoo rau kab rau kab. Nws teeb tsa qhov yooj yim uas yuav tsum tau rau cov khoom siv khoom thiab kuaj. PSL1 cov kav dej yog qhov tsim nyog rau cov ntawv thov xa xov dav dav.
Cov txheej txheem tsim khoom
- Ntaub ntawv: Cov ntaub ntawv raw siv rau kev tsim cov khoom API 5L PSL1 PIPES suav nrog kev siv, bille, billets, lossis daim hlau. Cov ntaub ntawv no feem ntau yog tsim los ntawm cov pa roj hmab, hluav taws xob rauv, lossis qhib hearth txheej txheem, ua ke nrog ladle refining.
- Hom Pipes: PSL1 cov kav dej tuaj yeem yog qhov tsis muaj dab tsi los yog welded. Seamless kav yog tsim los ntawm kub dov lossis extrusion cov txheej txheem, thaum welded kav hlau tuaj yeem siv cov qauv hluav taws xob xws li hluav taws xob vuam (pom).
