API 5L X42 lossis L290 Kab Pipe Description
X42 pipeline steel tubing yog seamless steel yeeb nkab ua los ntawm siab - cov pa roj carbon zoo, nrog rau nws cov khoom siv qib API 5L X42, sib npaug rau L290 pipeline tubing.
X42 thiab L290 pipeline tubing muaj ob hom: seamless kav thiab welded steel kav. Cov tubing tubing kawg no tuaj yeem ua ntau hom, xws li qhov xaus, threaded xaus, thiab qhov (socket) xaus. Cov kev sib txuas ua ke rau cov raj xa dej no muaj xws li kev sib txuas, kev sib txuas, thiab kev sib txuas ntawm lub qhov (socket).
X42 thiab L290 pipeline tubing yog siv los thauj cov roj, roj, thiab dej tawm hauv av los ntawm cov raj xa dej mus rau cov lag luam roj thiab roj.

Mechanical Property
Kev Xeem Xeem
Hydrostatic xeem
Cov yeeb nkab kom tiv taus qhov kev sim hydrostatic yam tsis muaj qhov xau los ntawm cov hlua khi los yog cov yeeb nkab lub cev. Jointers tsis tas yuav tsum tau kuaj hydrostatic muab cov yeeb nkab seem siv tau zoo kuaj.
Khoov xeem
Tsis muaj kab nrib pleb yuav tsum tshwm sim nyob rau hauv ib feem ntawm daim ntawv xeem thiab tsis muaj qhov qhib qhov vuam yuav tsum tshwm sim.
Kev ntsuam xyuas
Kev lees txais cov qauv rau kev xeem flattening yuav tsum yog:
EW cev D<12.750 in:
X60 T 500 in. Yuav tsum tsis txhob qhib qhov vuam ua ntej qhov kev ncua deb ntawm daim hlau yog tsawg dua 66% ntawm qhov qub sab nraud txoj kab uas hla. Rau txhua qib thiab phab ntsa, 50%.
Rau cov yeeb nkab nrog D / t> 10, yuav tsum tsis txhob qhib qhov vuam ua ntej qhov kev ncua deb ntawm daim hlau yog tsawg dua 30% ntawm qhov qub sab nraud.
Rau lwm qhov ntau thiab tsawg xa mus rau tag nrho API 5L specification.
CVN cuam tshuam kuaj rau PSL2
Ntau PSL2 cov yeeb nkab loj thiab qib xav tau CVN. Seamless yeeb nkab yuav tsum tau kuaj hauv lub cev. Welded yeeb nkab yog yuav tsum tau kuaj nyob rau hauv lub cev, yeeb nkab weld thiab tshav kub- cuam tshuam cheeb tsam. Xa mus rau tag nrho API 5L specification rau daim duab ntawm qhov ntau thiab tsawg thiab qib thiab yuav tsum tau absorbed zog qhov tseem ceeb.
