Nws yog seamless steel yeeb nkab uas yuav tsum tau ua raws li cov tshuaj muaj pes tsawg leeg thiab cov cuab yeej cuab tam ntawm Qib B ntawm API 5L, ASTM A106, thiab ASTM A53 tib lub sijhawm.
Hom yeeb nkab no tuaj yeem siv tau yooj yim hauv cov haujlwm sib txawv yam tsis tas yuav txhawj xeeb txog cov teeb meem kev sib raug zoo.Nws kuj tseem ua kom yooj yim rau kev tswj cov khoom lag luam los ntawm kev txo qhov xav tau los yuav cov raj ntawm ntau cov qauv sib txawv.
Nco tseg: 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 Steelyog cov chaw tsim khoom thiab cov chaw tsim khoom hauv Suav teb, tshwj xeeb hauv kev tsim thiab muab cov pa roj carbon seamless puag ncig rau cov kua thiab roj siv.Txij li thaum peb tsim nyob rau xyoo 2014, peb cov khoom tau raug xa tawm mus rau ntau lub teb chaws thiab cheeb tsam xws li Australia, Canada, Is Nrias teb, Saudi Arabia, thiab lwm yam, thiab peb tau txais kev nplua nuj nyob hauv kev lag luam thoob ntiaj teb.
Peb tsim cov yeeb nkab steel hauv kev ua raws li cov qauv thoob ntiaj teb xws li API 5L, ASTM A106, thiab ASTM A53 kom ntseeg tau cov khoom zoo thiab cov qauv tsim.Cov khoom lag luam npog seamless steel kav nrog sab nraud diameters ntawm 10.3 - 660 hli thiab thicknesses ntawm 2 - 100 hli.
Nrog ntau tshaj 8,000 tons ntawm seamless steel kav hauv Tshuag, peb muaj peev xwm los xyuas kom meej cov khoom xa tuaj ntawm qhov ntau thiab tsawg.Rau hom tshwj xeeb thiab qhov ntau thiab tsawg, peb kuj muab cov kev pabcuam customized tsim kom tau raws li cov neeg siv khoom tshwj xeeb.
Seamless steel tubesyog tsim nyob rau hauv ob lub ntsiab txheej txheem: kub xov thiab txias daim duab.
DN ≤ 40 tuaj yeem ua kom kub tiav lossis txias kos, feem ntau yog kos txias.
DN ≥ 50 yuav tsum kub tiav.Cold-drawn seamless steel tubes kuj muaj raws li qhov kev thov.
| Nominal Dia | DN 6-650 [NPS 1/8 - 26] |
| Specified Outer Diameter | 10.3-660mm [0.405-26 nyob rau hauv.] |
| Chav kawm hnyav | STD (Standard), XS (Ntxiv Strong), XXS (ob npaug ntxiv zog) |
| Teem caij No. | Teem caij 10, Teem 20, Teem 30, Teem 40, Teem 60, Teem 80, Teem 100, Teem 120, Teem 140, Teem 160, |
Txhawm rau kom ntseeg tau tias cov yeeb nkab ua tau raws li cov txheej txheem tshuaj lom neeg ntawm Qib B ntawm tag nrho peb cov qauv, API 5L, ASTM A106, thiab ASTM A53, cov tshuaj muaj pes tsawg leeg ntawm cov khoom yuav tsum nruj nruj thaum lub sijhawm tsim khoom.Cov hauv qab no yog cov kev cai tshwj xeeb rau cov tshuaj muaj pes tsawg leeg ntawm peb cov qauv no:
API 5L Qib B Chemical Composition
ASTM A106 Qib B Chemical Composition
ASTM A53 Qib B Chemical Composition
| Kuaj | API 5L PSL1 Qib B | ASTM A106 Qib B | ASTM A53 Qib B | |
| Yield zog, min | MPa [psi] | 245 [35,500] | 240 [35,000] | 240 [35,000] |
| Tensile zog, min | MPa [psi] | 415 [60,200] | 415 [60,000] | 415 [60,000] |
Kev sib piv ntawm cov kev xav tau ntawm cov neeg kho tshuab rau Qib B hauv API 5L, ASTM A106, thiab ASTM A53 qhia tau hais tias lawv muaj tib yam kev xav tau rau tensile thiab yield zog.Qhov kev sib xws no yog lub hauv paus rau kev sib hloov ntawm cov qauv no thiab ua kom ntseeg tau tias cov khoom siv tubular tuaj yeem siv rau ntau yam kev siv yam tsis muaj kev txhawj xeeb rau cov khoom tsis sib xws.

Ntxiv nrog rau kev muab cov khoom zoo seamless steel raj,Botop Steelmuaj ntau yam kev pab cuam txheej txheej kom tau raws li qhov sib txawv ntawm kev tiv thaiv corrosion thiab ib puag ncig.
Hlau yeeb nkab txheej feem ntau yog categorized rau hauv kev tiv thaiv ib ntus thiab tiv thaiv corrosion mus ntev.Peb feem ntau pom seamless steel yeeb nkab coated nrog dub txheej, uas yog siv los muab kev tiv thaiv ib ntus kom txo qis corrosion thaum lub hiav txwv thauj mus los thiab cia cov yeeb nkab.
Hom txheej txheej rau kev tiv thaiv corrosion muaj xws lipleev xim, kub dip galvanizing, 3 LPE, FBE, thiab lwm yam.Kev xaiv cov txheej txheej zoo tsis tsuas yog pab kom ntev lub neej kev pab cuam ntawm cov yeeb nkab steel, tab sis kuj txo cov nqi khiav lag luam tag nrho.
API 5L, ASTM A106, thiab ASTM A53 Qib B seamless steel yeeb nkab feem ntau siv hauv cov kav dej rau kev thauj mus los ntawm chav dej, dej, roj, thiab huab cua.Cov raj no kuj tsim nyog rau kev khoov, flanges, thiab lwm yam kev ua haujlwm.
Botop Steel yeej ib txwm hais kom zoo raws li lub hauv paus ntawm lub tuam txhab, uas peb ntseeg tias yog tus yuam sij rau yeej cov neeg siv khoom kev ntseeg siab thiab kev lag luam lees paub.Hauv kev xyaum ua lag luam mus sij hawm ntev, peb tau sau cov kev paub nplua nuj thiab ntau qhov kev vam meej.
