Cov yeeb nkab API 5L yog cov yeeb nkab hlau carbon uas siv rau hauv cov roj thiab cov roj xa mus. Nws kuj tseem siv los thauj lwm yam kua xws li pa dej, dej, thiab av nkos.

Hom Kev Tsim Khoom

Cov lus qhia API 5L suav nrog ob hom kev tsim khoom welded thiab seamless.

Hom Welded: ERW, SAW, DSAW, LSAW, SSAW, HSAW Yeeb Nkab

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

ERW: Kev vuam hluav taws xob tsis kam, feem ntau siv rau cov yeeb nkab txoj kab uas hla tsawg dua 24 ntiv tes.

DSAW/SAWKev vuam ob sab submerged arc/submerged arc welding, lwm txoj kev vuam rau ERW siv rau cov kav dej loj dua.

LSAWKev vuam siv txoj hlua khi hauv qab dej ntev, siv rau cov yeeb nkab uas muaj txoj kab uas hla mus txog 48 nti. Kuj tseem hu ua txheej txheem tsim khoom JCOE.

SSAW/HSAWKev vuam siv txoj hlua khi ua los ntawm kauv/kauv vuam siv txoj hlua khi ua los ntawm kauv, siv rau cov yeeb nkab uas muaj txoj kab uas hla txog li 100 nti.

Tiv Tauj Peb Kom Paub Txog Qhov Txawv Ntawm ERW, LSAW, thiab SSAW yeeb nkab.

Cov Yeeb Nkab Tsis Muaj Qhov Txuas: Cov Yeeb Nkab Tsis Muaj Qhov Txuas Kub thiab Cov Yeeb Nkab Tsis Muaj Qhov Txuas Txias

Cov yeeb nkab tsis muaj qhov txuas feem ntau yog siv rau cov yeeb nkab me me (feem ntau tsawg dua 24 nti).

(Cov yeeb nkab hlau tsis muaj qhov sib txuas feem ntau siv dua li cov yeeb nkab vuam rau cov yeeb nkab uas muaj txoj kab uas hla tsawg dua 150 hli (6 nti).

Peb kuj muaj cov yeeb nkab loj uas tsis muaj qhov txuas. Siv cov txheej txheem tsim khoom kub-kub, peb tuaj yeem tsim cov yeeb nkab tsis muaj qhov txuas txog li 20 nti (508 mm) hauv txoj kab uas hla. Yog tias koj xav tau cov yeeb nkab tsis muaj qhov txuas loj dua 20 nti hauv txoj kab uas hla, peb tuaj yeem tsim nws siv cov txheej txheem kub-nthuav dav txog li 40 nti (1016 mm) hauv txoj kab uas hla.

API 5L Yeeb Nkab Qib

API 5L npog Qib B, X42, X46, X52, X56, X60, X65, X70, thiab X80.

Cov yeeb nkab hlau API 5L siv ntau hom hlau, suav nrog Qib B, X42, X46, X52, X56, X60, X65, X70, thiab X80. Thaum cov hlau qib nce ntxiv, kev tswj hwm cov pa roj carbon sib npaug yuav nruj dua thiab cov khoom siv zog ua haujlwm yuav siab dua.

Tsis tas li ntawd xwb, cov tshuaj lom neeg sib xyaw ntawm API 5L cov kav dej seamless thiab welded ntawm tib qib hlau sib txawv, nrog cov kav dej welded muaj cov kev cai nruj dua thiab cov ntsiab lus carbon thiab sulfur qis dua.

Qib Kev Qhia: PSL1, PSL2

PSL sawv cev rau Product Specification Level, uas suav nrog PSL1 thiab PSL2. Nws kuj tseem tuaj yeem nkag siab tias yog qib zoo.

PSL1 thiab PSL2 tsis yog tsuas yog sib txawv hauv kev xav tau kev kuaj xwb tab sis kuj tseem muaj cov tshuaj lom neeg thiab cov khoom siv kho tshuab.

PSL2 muaj cov kev cai nruj dua li PSL1 hais txog cov tshuaj lom neeg muaj pes tsawg leeg, cov khoom tensile, kev sim cuam tshuam, kev sim tsis puas tsuaj, thiab lwm yam.

Kev Ntsuas Kev Cuam Tshuam
PSL1 tsis tas yuav tsum tau kuaj qhov cuam tshuam, thaum PSL2 (tshwj tsis yog X80) ua li ntawd.

Kev Ntsuas Tsis Ua Rau Puas Tsuaj
PSL1 tsis xav tau kev sim tsis ua puas tsuaj, thaum PSL2 ua li ntawd.

(Kev sim tsis puas tsuaj: Kev sim tsis puas tsuaj thiab kev sim hauv tus qauv API 5L siv cov duab xoo hluav taws xob, ultrasonic, lossis lwm txoj kev (tsis rhuav tshem cov khoom) los nrhiav cov qhov tsis zoo thiab qhov tsis zoo hauv cov kav dej.)

Yog xav paub ntxiv, hu rau peb kom paub ntxiv txog qhov sib txawv ntawm API 5L PSL1 thiab PSL2.

Kev Ntim Khoom thiab Kev Thauj Mus Los

Kev ntim khoom yogfeem ntau liab qab, hlau xaim khi, heevmuaj zog.
Yog tias koj muaj cov kev xav tau tshwj xeeb, koj tuaj yeem sivkev ntim khoom tsis xeb, thiab zoo nkauj dua.

Cov kev ceev faj rau kev ntim khoom thiab kev thauj mus los ntawm cov kav hlau carbon
1.API 5L Cov Yeeb Nkab Hlauyuav tsum tau tiv thaiv los ntawm kev puas tsuaj los ntawm kev sib tsoo, extrusion thiab txiav thaum lub sijhawm thauj mus los, khaws cia thiab siv.
2. Thaum siv cov kav hlau carbon, koj yuav tsum ua raws li cov txheej txheem kev nyab xeeb thiab xyuam xim kom tiv thaiv kev tawg, hluav taws, lom thiab lwm yam xwm txheej.
3. Thaum siv,Cov hlau carbon API 5L Yeeb Nkabyuav tsum tsis txhob kov cov khoom kub thiab txias, cov khoom siv corrosive, thiab lwm yam. Yog tias siv rau hauv cov chaw ib puag ncig no, cov kav hlau carbon ua los ntawm cov khoom siv tshwj xeeb xws li kev tiv taus kub thiab kev tiv taus corrosion yuav tsum tau xaiv.
4. Thaum xaiv cov kav hlau carbon, cov kav hlau carbon ntawm cov ntaub ntawv tsim nyog thiab cov lus qhia yuav tsum tau xaiv raws li kev txiav txim siab dav dav xws li kev siv ib puag ncig, cov khoom nruab nrab, siab, kub thiab lwm yam.
5. Ua ntej siv cov kav hlau carbon, yuav tsum tau kuaj xyuas thiab sim kom paub tseeb tias lawv qhov zoo ua tau raws li qhov yuav tsum tau ua.
