Marine Welded Steel Yeeb Nkab

Marine Welded Steel Pipe · High Durability Series

Engineered for the Deep Hiav Txwv – Ua Kom Muaj Hwj Chim

Nyob rau hauv huab cua marine ib puag ncig-offshore platforms, subsea pipelines, chaw nres nkoj infrastructure, thiab hla- hiav txwv hla- lub durability, corrosion kuj, thiab structural kev ncaj ncees ntawm steel kav ncaj qha mus txiav txim qhov project lifecycles thiab cov nqi khiav lag luam. PebMarine High-Cov kav ntev Welded steel yeeb nkabyog lub hom phiaj-tsim los tiv taus siab salinity, muaj zog tam sim no, complex seabed tej yam kev mob, thiab thermal cycling. Nws redefines "kev pab mus sij hawm ntev" los ntawm kev siv technology siab heev thiab superior kev ua tau zoo.

Advanced manufacturing txheej txheem yog tus yuam sij rau realizing cov khoom ua tau zoo:

Kev Ua Tau Zoo: JCO txheej txheem txheej txheem (pre-bending, J-shape, C-shape, O-shape) kom meej geometric qhov ntev, muab lub hauv paus zoo rau kev vuam tom ntej.

Hybrid Vuam Technology: Ua ntej- vuam, welding sab hauv, thiab sab nraud vuam siv tag nrho cov pa roj-shielded hlau arc vuam (50%–70% CO₂ + 30%–50% Ar) nrog ER70S series vuam hlau. Los ntawm kev tswj cov vuam ceev (pre-weld 25-30 cm / min, sab hauv / sab nraud 18-23 cm / min) thiab interpass kub (130-170 degree), cov txheej txheem zoo daws cov teeb meem tshwm sim ntawm HAZ cov cuab yeej inhomogeneity thiab toughness degradation nyob rau hauv high{15} weldingstreng.

Tag Nrho -NDT Inspection: Los ntawm steel phaj ultrasonic kuaj rau vuam X-ray tshuaj ntsuam xyuas, vuam ultrasonic kuaj, thiab yeeb nkab- kawg sib nqus particle soj ntsuam.

Marine ib puag ncig nthuav qhia kev sib tw corrosion rau cov kav dej. Peb cov qib siab - durability series txais ntau- txheej txheej tiv thaiv zoo:

Base Material Corrosion-Resistant Design: Kos rau lub tswv yim ntawm chromium- bearing weathering steel, qhov sib ntxiv ntawm Cr thiab lwm yam alloying ntsiab rau lub hauv paus hlau txhawb kev tsim ntawm ib tug denser xeb txheej uas zoo inhibits oxygen nkag mus rau - corrosion tus nqi yuav raug txo kom tsawg tshaj li ib nrab ntawm cov hlau zoo tib yam.

High -Kev Ua Haujlwm Sab Nraud Txheej Txheej Txheej Txheej: Ua raws li cov qauv thoob ntiaj teb suav nrog DNV RP F106 thiab ISO 21809-1, nrog ntau txoj kev xaiv txheej:

Fusion Bonded Epoxy (FBE): Ib leeg lossis dual - txheej, muab cov adhesion zoo thiab cathodic disbondment kuj.

Peb- Txheej Polyethylene / Polypropylene (3LPE / 3LPP): Kev sib xyaw ua ke los tiv thaiv- kev ua haujlwm corrosion ntawm epoxy, adhesion ntawm copolymer adhesive, thiab cov neeg kho tshuab kev tiv thaiv ntawm polyolefin txheej - mus- mus rau kev daws rau subsea pipelines thiab av ib puag ncig.

Yuav kom ua tau raws li cov kev cai sib txawv ntawm marine engineering tej yaam num, cov khoom muaj nyob rau hauv ntau qib:

Standard Strength Qib: Q355B qib muaj – yield zog Ntau dua los yog sib npaug rau 355MPa, tensile zog 470–630MPa, carbon sib npaug (Ceq) Tsawg dua los yog sib npaug rau 0.40%. Weldability zoo heev, haum rau offshore platform pawg, trestles, thiab lwm yam kev siv cov qauv.

Ultra-High Strength Qib: Rau kev xav tau cov roj dej tob & roj kav dej thiab tus kheej - txhawb nqa qhov chaw drilling platform, qib EQ70 (sib npaug rau API 5L X100Q) muaj, nrogYam tsawg kawg nkaus tawm lub zog ntawm 690MPa. Qhov no ua rau cov phab ntsa thickness txo thiab cov qauv teeb pom kev zoo thaum tswj kev ncaj ncees, txo cov nqi tag nrho.

Offshore cua foundations (jackets, monopiles)

Subsea roj / gas kis pipelines, subsea dej pipelines

Chaw nres nkoj thiab wharf piling systems, trestles, thiab revetment ua haujlwm

Marine Welded Steel Pipe · High Durability Series - Nrog rau cov ntaub ntawv raug, cov txheej txheem siab heev, thiab kev tiv thaiv ntau - txheej, xa cov kev tiv thaiv kev nyab xeeb rau koj cov khoom muaj nqis marine.
