Manufactured to BS2871/EN1057/ASTM B88 standards, our C12200 (T2 Copper) seamless tubes deliver unmatched corrosion resistance, thermal conductivity, and durability for critical offshore oil&gas,shipbuilding,and seawater systems.
At EZsteel industry, we pride ourselves on delivering world-class hospitality tailored to international clients across the marine, oil & gas, and industrial sectors. Our multicultural team ensures seamless communication in English, Spanish, and Arabic, with dedicated protocol specialists for key markets.
Secure & Customized Pipe Export Solutions
we ensure 100% damage-free delivery of steel pipes with multi-layer protective packaging tailored to your needs. Our standard export packaging includes:
VCI anti-rust film + steel-strapped wooden crates (ISPM15 compliant)
3D laser-scanned loading plans to prevent transit shifts
Customizable options: epoxy end caps, vacuum sealing, or container desiccant systems
We've successfully shipped to 45+ countries, adapting to regional requirements:
• Middle East: Sandproof wrapping for desert transit
• Europe: Recyclable packaging per EU Green Deal
• Tropical zones: Mold-resistant treatments
Every shipment includes real-time GPS tracking and MTC/certificate bundles. Tell us your needs - we'll engineer the perfect packaging.
Ship seawater cooling system
• Main/auxiliary machine central cooler inlet and outlet water pipes, air cooler, cylinder liner water cooler
Typical specifications: Outer diameter 10-219mm, wall thickness 1-4mm, annealed state M
• Advantages: Resistant to chloride ion pitting corrosion, low biofilm adhesion, long-term operation corrosion rate < 0.025mm /a
Ship fire protection and ballast system
• Fire hose, foam proportioning mixer, ballast pump discharge pipe
• Use BS 2871-2, CN102 90-10 or CN107 70-30, PN10-PN25
• Key requirements: Reliable sealing, resistant to water hammer, and capable of withstanding seawater at 35,000 ppm Cl-
Offshore oil and gas platform
• Crude oil/natural gas transportation heating pipes, seawater lifting pipes, and electrolytic chlorine production pipelines
• 70-30 alloy is used in the high-pressure section (>2.5 MPa), and 90-10 is used in the atmospheric pressure section
• Certified by DNV/ABS classification societies, it meets the requirements of vibration and salt spray environments
Architecture and Municipal Water Supply and Drainage (Coastal)
• High-rise building seawater source heat pumps, coastal fire protection pipe networks, and seawater desalination devices
• BS 2871-2 seamless coil is adopted, with a length of 6-12 m or 20-200 m
It can replace 316L, eliminating the need for cathodic protection and reducing the total life cycle cost
Other Marine engineering scenarios
• LNG carrier cryogenic pipeline (impact toughness qualified at -196 °C)
High-pressure pipes for submarine hydraulic and seawater hydraulic systems (70-30 alloy)
• Offshore wind power foundation seawater circulation cooling and seawater desulfurization scrubber tower
