KHOOM

Tianjin Brisk Steeltsom rau cov khoom tsim thiab muab cov seem hollow thiab steel yeeb nkab

Nyob rau hauv lub ntiaj teb no lub zog, petrochemical, thiab siab - kev thauj mus los ntawm cov dej siab, kev ua haujlwm tsis zoo tsis yog ib qho kev xaiv.Kub Rolled API 5L Qib B Seamless Kab Yeebyog tus qauv kub kev lag luam rau kev ntseeg siab, siab -kev ncaj ncees pipeline infrastructure. Tsim los ntawm kev kub rotary tho thiab nruam extrusion yam tsis muaj longitudinal los yog helical weld seam, no seamless yeeb nkab xa cov qauv, isotropic mechanical zog thoob plaws nws tag nrho 360-degree cross-section.

Tsim los thauj cov roj qab zib thiab qaub qaub, roj av, cov khoom siv roj ua kom zoo, thiab siab - cov kua dej muaj zog, API 5L Qib B Seamless Line Pipe tshem tawm cov kev ua haujlwm tsis zoo, cua sov- cuam tshuam rau cheeb tsam (HAZ) kev ntxhov siab, thiab seam corrosion txaus ntshai cuam tshuam nrog cov kav dej. Ua hauj lwm raws li nruj specifications ntawm lubLub koom haum American Petroleum (API), cov khoom no muaj qhov zoo tshaj qhov sib npaug ntawm cov khoom muaj zog, ductility, tawg toughness, thiab thaj chaw weldability, ua rau nws qhov kev xav tau tshwj xeeb rau cov kab sib sau ua ke, midstream trunklines, thiab downstream processing facility loops.

Lub cev thiab metallurgical superiority ntawm peb API 5L Qib B seamless kab yeeb nkab stems los ntawm ib tug tag nrho automated, xeev - ntawm - lub -art kub teb tho thiab mandrel zeb extrusion kab:

1. Billet Reheating:Daim ntawv pov thawj tseem ceeb tas mus li- cam khwb cia puag ncig steel billets yog rhuab nyob rau hauv ib lub computer -tswj rotary hearth cub rau yas deformation kub (kwv yees . 1250℃).
2. Hla -Yob Piercing:Lub rhuab billet yog pub rau hauv tus ntoo khaub lig- yob tho tshuab. Dual tapered rollers tig lub billet ntawm kev kub ceev tshaj qhov chaw ntsaws sab hauv, hloov cov khoom tseem ceeb rau hauv lub plhaub hollow seamless.
3. Continuous Mandrel Mill Rolling (MPM):Lub siab -precision internal mandrel bar yog muab tso rau hauv lub plhaub hollow li multi- sawv ntsug rolls compress lub phab ntsa thickness thiab elongate cov yeeb nkab, kom ntseeg tau tshwj xeeb concentricity.
4. Stretch Txo & Kub Sizing:Lub raj xa mus los ntawm ntau- sawv ntsug ncab txo zeb (SRM) kom ua tiav qhov tseeb ntawm sab nraud thiab phab ntsa tuab.
5. Hauv -Line Normalizing Thaum tshav kub kub kho:Txhawm rau txhim kho cov qoob loo loj thiab tshem tawm cov kev ntxhov siab ntawm qhov seem, cov kav dej tau raug rau tag nrho -lub cev austenitizing / normalizing (900℃- 930} degree), ua ib qho ferrite zoo li -pearlite microstructure nrog rau qhov muaj zog toughness.

Txhawm rau kom muaj kev sib koom ua ke tsis sib haum xeeb rau hauv kev tsim qauv engineering thoob ntiaj teb thiab thoob ntiaj teb EPC cov txheej txheem kev yuav khoom, peb cov kav dej kub dov seamless kab ua raws li nruj me ntsis rau saum -tier thoob ntiaj teb cov qauv:

TSEEM CEEB GLOBAL STANDARDS:

• API Spec 5L (American Petroleum Institute) - Kab Pipe Specification
• ASTM A106 / A106M - Seamless Carbon Steel Yeeb Nkab rau Siab -Temp Service
• ASTM A53 / A53M - Seamless Steel Yeeb Nkab rau Kev Siv Dej thiab Siv Dej
• TS EN 10204 Hom 3.1 / 3.2 - Cov ntaub ntawv tshuaj xyuas cov khoom siv hlau

Kev tawg: PSL1 vs. PSL2 Zoo Qib

Thaum qhia API 5L Qib B yeeb nkab, xaiv ntawmKhoom Specification Qib 1 (PSL1)thiabKhoom Specification Qib 2 (PSL2)Nws yog ib qho tseem ceeb rau kev nyab xeeb ntawm qhov project thiab tus nqi efficiency:

Peb kub dov API 5L Qib B seamless kab yeeb nkab tau muab rau hauv ntau yam ntawm cov kab uas hla sab nraud, cov sij hawm, thiab qhov ntev matrices kom tau raws li qhov xav tau ntawm cov qauv tsim:

Mechanical Properties & Chemical Composition (API 5L Qib B / PSL1 & PSL2)

Yam tsawg kawg yield zog=245MPa (35,500PSI) Yam tsawg kawg Tensile Strength=415MPa (60,200 PSI)

Dimensional Matrix & Tolerances

Txhawm rau tiv thaiv kev xeb hauv av, av txav, huab cua raug, thiab kev nkag rau hauv hiav txwv, peb muab cov koom haum ua tiav - siv cov kev kho deg thiab kev ua haujlwm:

• 3-Layer Polyethylene / Polypropylene (3LPE / 3LPP):Muab kev tiv thaiv kev tiv thaiv kev tiv thaiv tshwj xeeb thiab ntev - lub sij hawm dielectric barrier zog rau underground cross- lub teb chaws pipelines khiav mus txog 110℃.
• Fusion-Tshuaj Epoxy (FBE & Dual-Txheej FBE):Hwm tiv thaiv-corrosion txheej muab muaj zog adhesion, kub stability, thiab tsis kam mus rau cathodic disbondment.
• Internal Liquid Epoxy Txheej:Smooth hauv ob sab phlu uas txo cov kev sib txhuam hydraulic, ua kom muaj peev xwm txaus, thiab tiv thaiv cov khoom siv paraffin wax tsim - nce.
• Kev cai Mechanical Processing:Precise kawg beveling, kev cai txiav - mus rau - ntev cov kev pab cuam, tiv thaiv - kev sib tsoo lub hau kawg, thiab kev cai khoov / swaging raws li kev thov.

• 100% Homogeneous siab ntsuas:Tsis muaj cov kab weld, tshem tawm cov ntsiab lus tsis muaj zog ntawm cov qauv thiab muab lub zog isotropic nyob rau hauv ob qho tib si longitudinal thiab hoop cov lus qhia.
• Exceptional Tsawg-Tsub Tsis Txaus Siab Toughness:PSL2 qib seamless yeeb nkab nthuav tawm siab Charpy V-Notch (CVN) absorbed zog (Ntau tshaj los yog sib npaug rau 100 Joules) ntawm sub-zero kub (mus txog -46 degree), tiv thaiv brittle fracture pib.
• High Collapse Resistance:Superior roundness and tight wall tolerances make it resilient against deepwater external pressures and downhole crushing forces.
• Optimized Field Weldability:Tsawg carbon cov ntsiab lus thiab nruj carbon sib npaug tswj (CE_IIWTsawg dua los yog sib npaug li 0.43%) tso cai rau kev sib txuas ceev ceev hauv qhov chaw nrog qhov yuav tsum tau ua kom sov tsawg.

Xaiv txoj kev tsim cov yeeb nkab kom raug yog qhov tseem ceeb rau kev sib piv qhov project engineering xav tau nrog cov phiaj xwm nyiaj txiag:
