API 5L yeeb nkab yog hais txog cov pa roj carbon steel yeeb nkab siv hauv cov roj thiab cov roj xa hluav taws xob. Nws kuj tseem siv los thauj lwm cov kua dej xws li chav dej, dej, thiab av nkos.

Hom kev tsim khoom

API 5L specification npog ob qho tib si welded thiab seamless fabrication hom.

Welded Hom: ERW, SAW, DSAW, LSAW, SSAW, HSAW Pipe

Cov hom API 5L welded yeeb nkab yog raws li nram no:

ERW: Hluav taws xob tiv thaiv vuam, feem ntau yog siv rau cov yeeb nkab diameters tsawg dua 24 ntiv tes.

DSAW/SAW: Ob chav sided submerged arc vuam / submerged arc vuam, lwm txoj kev vuam rau ERW siv rau cov kav dej loj dua.

LSAW: Longitudinal submerged arc vuam, siv rau cov yeeb nkab diameters txog 48 ntiv tes. Kuj tseem hu ua JCOE fabrication process.

SSAW/HSAW: Kauv submerged arc vuam / kauv submerged arc vuam, siv rau cov yeeb nkab diameters txog 100 ntiv tes.

Tiv tauj peb kom paub qhov txawv ntawm ERW, LSAW, thiab SSAW yeeb nkab.

Hom Seamless Yeeb Nkab: Kub dov seamless yeeb nkab Txias dov

seamless steel yeeb nkab feem ntau yog ua haujlwm rau cov kav dej me me (feem ntau tsawg dua 24 ntiv tes).
(Seamless steel yeeb nkab yog nyiam dua welded yeeb nkab rau txoj kab uas hla tsawg dua 150 hli (6 hauv)).
Peb ua qhov loj txoj kab uas hla seamless yeeb nkab kuj. Los ntawm kev siv cov txheej txheem kub-kuav los tiag, seamless yeeb nkab nrog lub siab tshaj plaws txoj kab uas hla ntawm 20 ntiv tes (508 hli) tuaj yeem tsim. Yog tias koj xav tau seamless yeeb nkab nrog txoj kab uas hla> 20 ", peb tuaj yeem tsim cov yeeb nkab seamless los ntawm cov txheej txheem kub-expanded nrog txoj kab uas hla mus txog 40" (1016 hli).

API 5L Yeeb Nkab Qib

API 5L suav nrog qib B, X42, X46, X52, X56, X60, X65, X70 thiab X80.

API 5L Steel Pipe muaj nyob rau hauv ntau qib steel xws li Qib B, X42, X46, X52, X56, X60, X65, X70 thiab X80. Cov qib siab dua ntawm cov hlau, qhov nruj dua qhov sib npaug ntawm cov pa roj carbon monoxide tswj thiab siab dua cov cuab yeej siv zog.

Ntxiv mus, cov tshuaj pleev ib ce ntawm welded thiab seamless API 5L kav nrog tib qib steel muaj qhov sib txawv, uas cov welded kav muaj kev xav tau ntau dua thiab cov ntsiab lus ntawm cov pa roj carbon thiab sulfur tsawg dua.

Specification Qib: PSL1, PSL2

PSL yog luv rau Cov Khoom Qhia Qib thiab muaj PSL1 thiab PSL2. Nws yog ib yam dab tsi zoo li qib zoo.

PSL1 thiab PSL2 sib txawv tsis tsuas yog nyob rau hauv kev sim, tab sis kuj cov tshuaj muaj pes tsawg leeg thiab cov neeg kho tshuab zog.

PSL2 yog nruj dua li PSL1 hais txog cov tshuaj muaj pes tsawg leeg, tensile zog, cuam tshuam kev kuaj, tsis muaj kev puas tsuaj, thiab lwm yam.
Kev sim cuam tshuam

Kev ntsuam xyuas cuam tshuam - Tsis tas yuav tsum muaj rau PSL1, tab sis yog rau PSL2 (tshwj tsis yog X80).
Kev kuaj tsis muaj kev puas tsuaj

PSL1 tsis tas yuav muaj kev sim tsis zoo tab sis PSL2 ua.

(Kev ntsuam xyuas tsis muaj kev puas tsuaj: Kev sim tsis muaj kev puas tsuaj thiab kev sim hauv API 5L tus qauv siv hluav taws xob, ultrasonic, lossis lwm txoj hauv kev (tsis muaj kev rhuav tshem cov khoom) txhawm rau txheeb xyuas qhov tsis xws luag thiab tsis zoo hauv cov kav dej.)
