Adopting advanced mechanical spinning composite technology, the mechanical composite steel pipe closely bonds two complementary metal materials (usually carbon steel as the base pipe, and stainless steel, duplex steel, nickel-based alloy, titanium alloy, or Monel alloy as the inner liner) through elastic and plastic deformation. It requires no high-temperature fusion, featuring full-process green environmental protection and high energy efficiency. Strictly complying with international and industry standards such as API-5LD, DNV-ST-F101, SHELL DEP 31.40.20.32-Gen., ADNOC-AGES, GB/T31940, and CJ/T 192, the product combines the high strength and high pressure-bearing capacity of the outer base pipe with the corrosion resistance and wear resistance of the inner cladding, effectively solving the industry pain points of "insufficient strength" or "poor corrosion resistance" of single-material pipes.

Outstanding Core Advantages: Stable bonding strength, capable of withstanding the transportation of various media; cost is much lower than that of pure alloy pipes, with excellent cost performance. Mature production process, optimized through more than 20 years of actual production, complete specifications, and can be customized with different calibers and wall thicknesses according to needs, accurately covering designated industries—including oil and gas, chemical industry, marine engineering, electric power, medicine and food and beverage, urban water supply/heating/gas and other industrial scenarios. With the characteristics of economy and practicality, convenient installation and low maintenance cost, it has become the preferred solution for the upgrading of small and medium-sized engineering pipelines in various industries, helping customers reduce initial investment and later operation and maintenance costs, and balancing practicality and economy.
