Api 5l Kab Yeeb Nkab Qib B Rau X70 Od Los Ntawm 219mm Mus Rau 3500mm

Kev Piav Qhia Luv:

Cov lus qhia no yog los muab cov qauv tsim khoom rau cov kav dej xa dej, roj thiab roj hauv kev lag luam roj thiab roj av.

Muaj ob qib kev qhia tshwj xeeb ntawm cov khoom, PSL 1 thiab PSL 2, PSL 2 muaj cov kev cai yuav tsum tau ua rau cov pa roj carbon sib npaug, qhov tawv tawv, lub zog siab tshaj plaws thiab lub zog tensile.

Qib B, X42, X46, X52, X56, X60, X65, X70 thiab X80.

Cangzhou Spiral Steel pipes group co., ltd muab cov kav dej SAWH uas npog qib los ntawm API B txog X70, peb tau txais daim ntawv pov thawj API 5L xyoo dhau los thiab tam sim no peb cov kav dej siv dav los ntawm CNPC, CPECC rau lawv cov haujlwm kav dej.

Kev Ntsuas Hydrostatic

cov lus piav qhia txog khoom1

Cov yeeb nkab yuav tsum tiv taus qhov kev sim hydrostatic yam tsis muaj qhov xau los ntawm cov weld seam lossis lub cev yeeb nkab
Cov khoom sib koom ua ke tsis tas yuav tsum tau kuaj hydrostatically, tsuav yog cov feem ntawm cov yeeb nkab siv los cim cov khoom sib koom ua ke tau raug kuaj hydrostatically ua ntej kev ua haujlwm sib koom ua ke.

Kev taug qab tau:
Rau cov yeeb nkab PSL 1, cov chaw tsim khoom yuav tsum tsim thiab ua raws li cov txheej txheem sau tseg rau kev tswj hwm:
Qhov sib piv ntawm qhov kub kom txog rau thaum txhua qhov kev ntsuam xyuas tshuaj lom neeg raug ua tiav thiab ua raws li cov kev cai tshwj xeeb tau qhia.
Qhov kev sib piv ntawm chav kuaj thiab chav kuaj kom txog rau thaum txhua qhov kev sim kho tshuab raug ua tiav thiab ua raws li cov kev cai tshwj xeeb tau pom.
Rau cov yeeb nkab PSL 2, tus neeg tsim khoom yuav tsum tsim thiab ua raws li cov txheej txheem sau tseg rau kev tswj hwm qhov kub thiab qhov sib piv ntawm chav kuaj rau cov yeeb nkab ntawd. Cov txheej txheem no yuav tsum muab cov hau kev rau kev taug qab txhua qhov ntev ntawm cov yeeb nkab mus rau chav kuaj thiab cov txiaj ntsig ntawm kev kuaj tshuaj lom neeg.
