Nws yog cov yeeb nkab hlau tsis muaj qhov sib txuas uas yuav tsum ua tau raws li cov tshuaj lom neeg thiab cov khoom siv kho tshuab ntawm Qib B ntawm API 5L, ASTM A106, thiab ASTM A53 tib lub sijhawm.
Cov yeeb nkab hom no siv tau yooj yim hauv ntau yam haujlwm sib txawv yam tsis tas txhawj txog cov teeb meem sib xws. Nws kuj ua rau kev tswj hwm cov khoom muag yooj yim dua los ntawm kev txo qhov xav tau yuav cov yeeb nkab ntawm ntau tus qauv sib txawv.
Lus Cim: Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias API 5L GR.B ntawm no yog hais txog API 5L PSL1 qib B.
Botop Hlauyog ib lub tuam txhab tsim thiab muag cov yeeb nkab hlau ua lag luam hauv Suav teb, tshwj xeeb hauv kev tsim thiab muab cov yeeb nkab hlau tsis muaj seamless rau cov kua thiab roj. Txij li thaum peb tau tsim tsa xyoo 2014, peb cov khoom tau raug xa tawm mus rau ntau lub tebchaws thiab thaj chaw xws li Australia, Canada, Is Nrias teb, Saudi Arabia, thiab lwm yam, thiab peb tau khaws cov kev paub nplua nuj hauv kev lag luam thoob ntiaj teb.
Peb tsim cov kav hlau raws li cov qauv thoob ntiaj teb xws li API 5L, ASTM A106, thiab ASTM A53 kom ntseeg tau tias cov khoom zoo thiab raws li tus qauv. Cov khoom lag luam suav nrog cov kav hlau tsis muaj qhov txuas nrog sab nraud ntawm 10.3 - 660 mm thiab tuab ntawm 2 - 100 mm.
Peb muaj ntau tshaj 8,000 tons ntawm cov yeeb nkab hlau tsis muaj seamless uas peb muaj, yog li peb tuaj yeem xa cov yeeb nkab uas muaj qhov loj me ib txwm tam sim ntawd. Rau cov hom thiab qhov loj me tshwj xeeb, peb kuj muab cov kev pabcuam tsim khoom tshwj xeeb kom tau raws li cov neeg siv khoom xav tau.
Cov kav hlau tsis muaj qhov txuasraug tsim tawm hauv ob txoj hauv kev tseem ceeb: kev ua tiav kub thiab kev kos duab txias.
DN ≤ 40 tuaj yeem ua rau kub tiav lossis txias kos, feem ntau txias kos.
DN ≥ 50 yuav tsum tau ua kom sov. Cov kav hlau tsis muaj qhov sib txuas txias kuj muaj thaum thov.

Yuav kom ntseeg tau tias cov yeeb nkab ua tau raws li cov kev cai ntawm cov tshuaj lom neeg ntawm Qib B ntawm peb tus qauv, API 5L, ASTM A106, thiab ASTM A53, cov tshuaj lom neeg ntawm cov khoom siv yuav tsum tau tswj hwm nruj thaum lub sijhawm tsim khoom. Cov hauv qab no yog cov kev cai tshwj xeeb rau cov tshuaj lom neeg ntawm peb tus qauv no:
API 5L Qib B Cov Tshuaj Lom Zem
ASTM A106 Qib B Cov Tshuaj Lom Zem
ASTM A53 Qib B Cov Tshuaj Lom Zem
| Kev Ntsuas | API 5L PSL1 Qib B | ASTM A106 Qib B | ASTM A53 Qib B | |
| Lub zog tawm los, min | MPa [psi] | 245 [35,500] | 240 [35,000] | 240 [35,000] |
| Lub zog tensile, min | MPa [psi] | 415 [60,200] | 415 [60,000] | 415 [60,000] |
Kev sib piv ntawm cov kev cai kho tshuab rau Qib B hauv API 5L, ASTM A106, thiab ASTM A53 qhia tau tias lawv muaj tib yam kev cai rau tensile thiab yield strength. Qhov kev sib xws no yog lub hauv paus rau kev sib pauv ntawm cov qauv no thiab ua kom ntseeg tau tias cov khoom tubular tuaj yeem siv rau ntau yam kev siv yam tsis muaj kev txhawj xeeb txog cov khoom tsis sib xws.

Ntxiv rau kev muab cov kav hlau tsis muaj seamless zoo,Botop Hlaumuab ntau yam kev pabcuam pleev xim rau saum npoo kom tau raws li kev xav tau tiv thaiv kev xeb sib txawv thiab cov xwm txheej ib puag ncig.
Cov txheej txheem txheej txheem ntawm cov yeeb nkab hlau feem ntau yog muab faib ua kev tiv thaiv ib ntus thiab kev tiv thaiv xeb mus sij hawm ntev. Peb feem ntau pom cov yeeb nkab hlau tsis muaj qhov sib txuas nrog cov txheej txheem dub, uas yog siv los muab kev tiv thaiv ib ntus kom txo qhov xeb thaum thauj mus los hauv hiav txwv thiab khaws cia cov yeeb nkab.
Cov hom tshuaj pleev xim rau kev tiv thaiv xeb suav nrogpleev xim, kub dip galvanizing, 3LPE, FBE, thiab lwm yam. Kev xaiv cov txheej txheem kom raug tsis yog tsuas yog pab txuas lub neej ua haujlwm ntawm cov yeeb nkab hlau xwb tab sis kuj tseem txo cov nqi khiav lag luam tag nrho.
Cov yeeb nkab hlau tsis muaj seamless API 5L, ASTM A106, thiab ASTM A53 Qib B feem ntau siv rau hauv cov kav dej rau kev thauj mus los ntawm cov pa dej, dej, roj, thiab cua. Cov yeeb nkab no kuj tsim nyog rau kev ua cov khoov, flanges, thiab lwm yam kev ua haujlwm tsim.
Botop Steel yeej ib txwm hais kom zoo ua lub hauv paus ntawm lub tuam txhab, uas peb ntseeg tias yog qhov tseem ceeb rau kev yeej kev ntseeg siab ntawm cov neeg siv khoom thiab kev lees paub ntawm kev ua lag luam. Hauv kev coj ua lag luam mus sij hawm ntev, peb tau khaws cov kev paub nplua nuj thiab ntau qhov kev vam meej.
