API 5L Steel Yeeb Nkab Taw

API 5LFeem ntau yog hais txog pipeline steel yeeb nkab (pipeline yeeb nkab) ntawm kev siv ntawm tus qauv, xa hluav taws xobHlau Yeeb Nkabsuav nrog seamless steel yeeb nkab thiab welded steel yeeb nkab ob qeb. Tam sim no nyob rau hauv cov roj pipeline peb feem ntau siv welded steel yeeb nkab yeeb hom kauv submerged arc welded yeeb nkab (Tussaw), ncaj zeem submerged arc welded yeeb nkab (Lsaw), Kuj Vuam Yeeb Nkab (Hlob), Seamless Steel Yeeb NkabFeem ntau siv hauv cov raj xa dej uas hla yog tsawg dua 152 hli.

Tus qauv siv lub teb chaws GB / T 9711-2011 cov yeeb nkab rau cov xov hluav taws xob rau cov roj thiab roj kev lag luam tau muab tso ua ke raws li API 5L.

GB / T 9711-2011 Qhia rau kev tsim khoom rau seamless thiab vam meej steel kav (PSL1 thiab PSL1 thiab PSL1 thiab PSL1 thiab PSELINE TSHEB thauj mus los hauv cov roj thiab roj kev lag luam. Yog li ntawd, tus qauv tsuas yog siv rau Seamless Steel Kav thiab kev thauj khoom hlau, thiab tsis siv tau los pov cov kav hlau.

Cov Qib Qauv Hlau

Tus qauv qib ntawm cov khoom siv raw rau cov kav hlau hlau ntawm cov qauv API 5, x 5, x 5, x56, x56, x56, x56, x56, x56, x56, x56, x56, x56, x 5 Thiab kev tsim khoom kuj sib txawv, tab sis cov pa roj carbon ntau ntawm cov qib sib txawv cov qib yog tswj hwm.

 

Cov Qauv Zoo

Hauv API 5L yeeb nkab txheem, cov qauv zoo (lossis cov khoom siv hlau) rau cov yeeb nkab steel tau sib cais ua PSL1 thiab PSL2. PSl yog cov lus luv rau qib khoom tshwj xeeb.

PSL1 muab ib theem ntawm cov yeeb nkab ua haujlwm zoo; PSL2 ntxiv cov kev xav tau rau tshuaj muaj kuab lom, tsis muaj tshuaj lom, lub zog muaj zog, thiab ndes ntxiv.
