API 5Lseamless steel yeeb nkab yog seamless steel yeeb nkab rau pipeline steel ---API 5L seamless steel yeeb nkabrau pipeline steel, seamless steel yeeb nkab, pipeline steel khoom: GR.B, X42, X46, 52, X56, X60, X65, X70. Pipeline yeeb nkab yog siv los thauj cov roj, roj thiab dej tawm hauv av mus rau cov chaw lag luam roj thiab roj los ntawm cov kav dej. Cov kav dej muaj xws li cov kav dej seamless thiab welded steel kav, thiab lawv cov yeeb nkab kawg muaj qhov xaus, threaded xaus thiab qhov (socket) xaus; lawv txoj kev sib txuas yog vuam, txuas txuas, qhov txuas txuas, thiab lwm yam.
API 5L pipeline steel, tus qauv: API5L ASTM ASME B36.10. DIN. Sab nraud txoj kab uas hla 13.7mm-1219.8mm, phab ntsa thickness ntau 2.11mm-100mm.
Ntev: 5.8m, 6m, 11.6m, 11.8m, 12m tsau ntev
Ntim: tshuaj tsuag pleev xim, bevel, yeeb nkab cap, galvanized steel pluaj bundling, daj lifting pluaj, zuag qhia tag nrho woven hnab ntim.
1. Cov yam ntxwv ntawm API 5LX42 seamless steel yeeb nkab

API 5LX42seamless steel yeeb nkab yog lub zog siab, qis-alloy steel yeeb nkab nrog lub zog ntawm 420MPa thiab zoo toughness thiab corrosion kuj. Cov yeeb nkab steel yog tsim los siv cov txheej txheem seamless, nrog cov phab ntsa du, tsis yooj yim rau cov av, thiab yooj yim los ntxuav thiab tswj. Tsis tas li ntawd, API 5LX42 seamless steel yeeb nkab kuj muaj qhov zoo weldability thiab tsis kam rau hydrogen-induced cracking, uas tuaj yeem ua tau raws li cov kev cai siv nyob rau hauv ib puag ncig hnyav.

2. Daim ntawv thov ntawm API 5LX42 seamless steel yeeb nkab

API 5LX42 seamless steel yeeb nkab yog tsuas yog siv rau hauv cov roj thiab roj pipelines, refineries, tshuaj nroj tsuag thiab lwm yam teb. Hais txog kev thauj mus los roj thiab roj, API 5LX42 seamless steel kav tuaj yeem tiv taus qhov chaw hnyav xws li kev kub siab, kub thiab corrosion los xyuas kom muaj kev nyab xeeb ntawm kev thauj mus los ntawm roj thiab roj. Hauv refineries thiab tshuaj nroj tsuag, API 5LX42 seamless steel kav yog siv los thauj ntau yam corrosive media, xws li sulfuric acid thiab hydrochloric acid.

3. Cov txheej txheem ntau lawm ntawm API 5LX42 seamless steel kav

Cov txheej txheem tsim khoom ntawm API 5LX42 seamless steel kav feem ntau suav nrog cov raj khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob Ntawm lawv, kev npaj tube dawb paug yog ib qho ntawm cov kev sib txuas tseem ceeb, thiab cov khoom siv raw khoom zoo yuav tsum tau xaiv thiab nruj me ntsis tshuaj xyuas thiab tswj. Thaum lub sij hawm perforation thiab dov txheej txheem, tsis xws li kub, ceev thiab siab yuav tsum tau tswj xyuas kom meej tias cov phab ntsa thickness, txoj kab uas hla thiab nto zoo ntawm cov yeeb nkab steel raws li qhov yuav tsum tau. Kev sib txuas ntawm kev kho cua sov tswj cov tsis xws li cua sov, lub sij hawm rwb thaiv tsev thiab txias ceev kom cov yeeb nkab steel kom tau txais lub koom haum zoo thiab kev ua haujlwm zoo. Thaum kawg, cov yeeb nkab steel yuav tsum tau soj ntsuam nruj thiab ntsuas kom ntseeg tau tias nws qhov zoo raws li tus qauv yuav tsum tau ua.
