API 5L Seamless Alloy Steel Yeeb Nkab

Lub zog rau qhov tob, Seamless rau Txoj Kev
-- API 5L Seamless Alloy Steel Yeeb Nkab · Engineered rau Roj & Gas Pipelines

Raws li kev tshawb nrhiav roj thiab roj nkag mus rau hauv kev sib sib zog nqus, thaj tsam ntawm ntug dej hiav txwv, thiab arctic permafrost, cov raj xa dej tau sib tw tsis yog los ntawm kev siab thiab kev ncua, tab sis los ntawm huab cua kub, corrosive media, thiab kev ua haujlwm ruaj khov.Qhov peb xa khoom yog ntau tshaj li cov yeeb nkab steel- nws yog lub pob txha txhim khu kev qha ntawm koj cov hlab ntsha.

Qhov no yog ibsiab -kev ua tau zoo seamless alloy steel yeeb nkabtsim los rau API Spec 5L, lub hom phiaj-tsim rau onshore thiab offshore roj & roj kis tau tus mob, sib sau ua ke, thiab ntev - tej yaam num nyob deb nroog. Los ntawm tag nrho - txheej txheem tswj dov thiab kev kho cua sov, nws ua tiav qhov kev pom zoo ntawm qhov sib npaug ntawm lub zog, toughness, weldability, thiab corrosion resistance, npog PSL1, PSL2, thiab Sour Service qib nrog tag nrho ua raws.

★ Metallurgical Purity - Kev tiv thaiv ua los ntawm Melt
Secondary refining (LF + VD) ua ke nrog dynamic soft txo thaum lub sij hawm nruam casting drastic txo phosphorus, sulfur, thiab tsis yog - metallic inclusions. Kev suav nrog kev ntsuas tsis tu ncua dhau ASTM E45 nplua -cov txheej txheem txheej txheem, cuam tshuam HIC txoj kev pib ua haujlwm zoo thiab muab cov kev pabcuam hauv qab zib- kev sib raug zoo.

★ Gradient Performance Architecture - Sib npaug zog nrog Ductility
Tsis yog nrhiav lub zog siab tshaj plaws nyob ib leeg, peb qhov kev ua kom zoo tshaj plaws - thiab -tempering (Q&T) txheej txheem tsim cov gradient microstructure thoob plaws phab ntsa. Rau qib X52–X80, peb tuav ib qho kev sib piv tsawg dua lossis sib npaug li 0.92 thaum khaws cia cov npoo kev nyab xeeb thiab cov elongation zoo ib yam, ua kom cov yeeb nkab haum rau hauv av txav thiab siab surges yam tsis muaj nkig teb.

★ Tag Nrho -Kev Hloov Kho Xov Xwm - Los ntawm Qab Zib rau Qab Zib, Ib Daim Ntawv Qhia Ua Ntej

○ Kev pabcuam qab zib: Txhim kho siab -kub creep tsis kam thiab khaws cia lub zog mus txog 350 degree, haum rau thermal rov qab chav - cov kab txhaj tshuaj.

○ Kev pabcuam ntub / qaub: Dual -cov kev xaiv tau ntawv pov thawj tawm tsam SSC thiab SOHIC, tau lees paub los tiv thaiv 720 teev yam tsis muaj kev puas tsuaj hauv pH Ntau dua lossis sib npaug rau 3.5 acidic ib puag ncig.

Siab -siab ntev-ntaub deb ntawm cov roj av / roj av

Offshore risers thiab subsea pipelines (DNV xaiv tau ntawv pov thawj muaj)

Qab zib - pabcuam kev sib sau ua ke

Hauv nroog siab -cov pa roj cia thiab faib tshuab

Kev txhaj tshuaj dej, kev txhaj tshuaj roj, thiab kev puas tsuaj manifolds

Our facility holds ISO 9001, ISO 14001, ISO 45001 certifications. Equipped with automated ultrasonic testing, hydrostatic testers, impact/drop-weight testers, and spectrometers, each batch undergoes stricter in-house inspection protocols. Outgoing quality maintains 100% documented traceability.

Kev xa khoom sai- Cov khoom lag luam tawm tswv yim thiab ntau- kev ua hauv paus; 15-hnub coj lub sijhawm rau cov qauv loj

Qhov chaw sib koom tes- Ntawm -kev pab ntawm qhov chaw kom haum-up, teb txheej, thiab NDT revalidation

Ntev -lub sij hawm Warranty- Lub neej lav ris rau cov khoom tsis xws luag; 24/7 thoob ntiaj teb tom qab -muag teb

Los ntawm cov suab puam sab hauv mus rau arctic tundra, los ntawm ultra- qhov dej tob mus rau qhov chaw ntab dej - peb txuas lub zog yav tom ntej nrog seamless zoo.
