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.
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.
Seamless yeeb nkab hom: Kub dov Seamless yeeb nkab thiab txias dov Seamless yeeb nkab
Seamless yeeb nkab feem ntau yog siv rau cov kav dej me me (feem ntau tsawg dua 24 ntiv tes).
(Seamless steel yeeb nkab yog feem ntau siv tshaj welded yeeb nkab rau cov yeeb nkab diameters tsawg dua 150 hli (6 nti).
Peb kuj muab txoj kab uas hla loj seamless yeeb nkab. Siv cov txheej txheem kub dov, peb tuaj yeem tsim cov yeeb nkab seamless mus txog 20 nti (508 mm) inch. Yog tias koj xav tau seamless yeeb nkab loj dua 20 ntiv tes hauv txoj kab uas hla, peb tuaj yeem tsim nws siv cov txheej txheem kub nthuav dav txog 40 ntiv tes (1016 hli) inch.




API 5L suav nrog Qib B, X42, X46, X52, X56, X60, X65, X70, thiab X80.
API 5L steel yeeb nkab siv ntau qib steel, suav nrog Qib B, X42, X46, X52, X56, X60, X65, X70, thiab X80. Raws li qib steel nce, cov pa roj carbon sib npaug tswj tau nruj dua thiab cov cuab yeej siv zog ua kom siab dua.
Tsis tas li ntawd, cov tshuaj muaj pes tsawg leeg ntawm API 5L seamless thiab welded kav ntawm tib qib steel sib txawv, nrog rau cov kav dej welded muaj cov kev cai nruj dua thiab qis dua cov ntsiab lus carbon thiab sulfur.

PSL stands rau Product Specification Level, uas suav nrog PSL1 thiab PSL2. Nws kuj tuaj yeem nkag siab tias yog qib zoo.
PSL1 thiab PSL2 txawv tsis tsuas yog nyob rau hauv cov kev cai xeem tab sis kuj nyob rau hauv tshuaj muaj pes tsawg leeg thiab txhua yam khoom.
PSL2 muaj cov kev cai 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
PSL1 tsis tas yuav muaj kev cuam tshuam, thaum PSL2 (tshwj tsis yog X80) ua.
Kev kuaj tsis muaj kev puas tsuaj
PSL1 tsis xav tau kev sim tsis muaj kev puas tsuaj, thaum PSL2 ua.

1.API 5L steel yeeb nkabyuav tsum tau tiv thaiv los ntawm kev puas tsuaj los ntawm kev sib tsoo, extrusion thiab txiav thaum lub sij hawm thauj mus los, cia thiab siv.
2. Thaum siv cov yeeb nkab carbon steel, koj yuav tsum ua raws li cov txheej txheem kev nyab xeeb ntawm kev ua haujlwm thiab ua tib zoo saib xyuas kom tsis txhob tawg, hluav taws kub, tshuaj lom thiab lwm yam xwm txheej.
3. Thaum siv,API 5L carbon steel yeeb nkabyuav tsum tsis txhob sib cuag nrog cov kub kub, corrosive media, thiab lwm yam. Yog hais tias siv nyob rau hauv cov cheeb tsam no, cov pa roj carbon steel kav ua los ntawm cov ntaub ntawv tshwj xeeb xws li kub tsis kam thiab corrosion kuj yuav tsum tau xaiv.
4. Thaum xaiv cov pa roj carbon steel kav, cov pa roj carbon steel kav ntawm cov khoom tsim nyog thiab cov lus qhia tshwj xeeb yuav tsum tau xaiv raws li kev xav tau zoo xws li kev siv ib puag ncig, nruab nrab cov khoom, siab, kub thiab lwm yam.
5. Ua ntej siv cov pa roj carbon steel kav, kev tshuaj xyuas thiab kev ntsuam xyuas yuav tsum tau ua los xyuas kom meej tias lawv cov khoom ua tau raws li qhov yuav tsum tau ua.
