In thermal power, nuclear power, new energy (offshore wind, photovoltaic energy storage) and UHV power facilities, pipeline systems face severe corrosion. Acidic slurry (SO₂, NOₓ) in FGD systems, high-temperature/high-pressure steam and seawater/freshwater corrosion in nuclear islands, salt spray in offshore wind, and corrosive media in UHV converter stations cause pitting, stress corrosion cracking and rust in traditional pipelines. Single-material pipelines (carbon steel, pure alloy) either lack corrosion resistance, have short service life and frequent maintenance, or are costly, endangering operation safety and increasing costs.

Jiangsu Zhongxin Pipe Sci-tech Co., Ltd. provides customized bimetallic composite pipe solutions for the power industry. With a "carbon steel/low alloy base layer + high-grade alloy cladding" structure and advanced metallurgical bonding, the products combine high pressure-bearing capacity and excellent corrosion resistance, effectively solving corrosion problems and ensuring long-term safe, efficient and economical operation of power systems.

Core Advantages

Excellent Corrosion Resistance for Multiple Scenarios
The cladding uses high-grade materials (2205/2507 duplex stainless steel, UNS N08825 / UNS N06625,316L, Hastelloy), effectively resisting acid slurry, salt spray, high-temperature steam, chloride ions and radioactive media. It adapts to thermal power desulfurization, nuclear power cooling and offshore wind hydraulic control, with corrosion resistance over 5 times that of traditional pipelines, eliminating leakage risks.

High Temperature/Pressure Resistance & Stable Mechanical Properties
Suitable for high-temperature/high-pressure power conditions, especially superheater/reheater pipelines of ultra-supercritical thermal power units (withstanding over 600℃). It has stable mechanical properties, excellent creep and impact resistance, withstanding high-pressure impact and ensuring continuous power equipment operation.

Firm Metallurgical Bonding, No Delamination
Advanced technologies (Automatic overlay welding) achieve firm metallurgical bonding (strength ≥350MPa), avoiding delamination, bubbling and interface corrosion. Service life is 10-15 years, far longer than traditional FRP (3-5 years) and carbon steel pipelines.

Outstanding Cost-Effectiveness, Lower Life-Cycle Costs
Compared with pure alloy pipes, it reduces precious metal usage by 25%-30% and cuts material costs. It also reduces pipeline replacement, maintenance and unplanned shutdowns, saving millions of yuan in annual O&M costs for power plants and wind projects, achieving "high performance + low cost".

Strict Quality Inspection & Industry Standard Compliance
Full-process non-destructive testing, hydrostatic testing and performance inspection are conducted. The products comply with GB/T 31940, API 5L, ASME, RCC-M and NACE MR0175/ISO 15156, providing customized products and full technical support for different power scenarios.

Wide Adaptability & Flexible Customization
Flexibly customize cladding materials and pipeline specifications to adapt to thermal power desulfurization, nuclear power steam, offshore wind hydraulic, UHV cooling and photovoltaic energy storage pipelines, balancing versatility and pertinence.
