In 2026, China's anti-corrosion coated steel pipe industry entered a new stage of high-quality development characterized by "steady growth in scale, optimized structure, and technological iteration," with the market size expected to reach 96.528 billion yuan, a year-on-year increase of 7.2%. As a core material for infrastructure construction, anti-corrosion coated steel pipes are widely used in key areas such as energy transmission, municipal water supply and drainage, chemical corrosion protection, and marine engineering. Driven by both "new infrastructure" and "urban renewal initiatives," the industry is showing three major development trends: high-end, green, and intelligent, becoming an important basic industry supporting the steady development of the national economy.
1. Market Pattern & Demand Layout
Energy transmission such as oil and natural gas remains the largest application field, followed by municipal water supply and drainage, chemical industry and marine engineering. With the global energy transition accelerating, emerging sectors including hydrogen energy pipelines and carbon capture projects are booming. Offshore wind power foundation anti-corrosion demand is rising rapidly, becoming a new growth driver of the industry.
Industrial clusters have taken shape obviously. North China forms a complete industrial chain covering raw material supply, steel pipe processing, anti-corrosion coating and quality inspection, with prominent cluster advantages. In the international market, China's anti-corrosion coated steel pipe exports keep growing, mainly exported to the Middle East and Southeast Asia. Facing trade barriers in North America, manufacturers are accelerating overseas factory layout to stabilize overseas market share.
2. Technological Innovation & Coating Upgrade
Anti-corrosion coating technology is the core competitiveness of the industry. It has evolved from traditional single-layer coating to composite and high-performance types. Main mainstream products include FBE fusion bonded epoxy powder coating, 3PE three-layer polyethylene coating and TPEP composite anti-corrosion coating. High-grade anti-corrosion pipes such as 3PE and TPEP are widely recognized for long service life and strong environmental adaptability.
Adopting Sa2.5 grade sandblasting rust removal ensures firm bonding between coating and steel pipe base. With the application of digital and intelligent technology, online flaw detection and automatic spraying systems are popularized, greatly reducing product defect rate and improving production efficiency and batch stability. New nano-modified anti-corrosion coatings and self-repairing intelligent coatings are under continuous research and development, further extending service life and adapting to extreme working conditions such as deep sea, chemical corrosion and high salt environment.
3. Policy Guidance & Green Development
Relevant national standards continue to be upgraded, putting forward higher requirements on coating weather resistance, impact resistance and service life. Environmental policies strictly control VOCs emissions, promoting the wide application of water-based paint and solvent-free powder coating, eliminating backward high-pollution and high-energy-consuming production capacity.
Global carbon neutrality policies make carbon footprint certification an important threshold for entering European and American markets. The industry is accelerating low-carbon transformation, optimizing production processes, reducing energy consumption and carbon emissions, and building a green and low-carbon manufacturing system. The renovation of old urban pipe networks and the construction of long-distance oil and gas pipelines continue to release steady market demand.
4. Industry Challenges & Development Opportunities
At present, the industry presents obvious structural differentiation. The profit margin of conventional standard coated pipes is compressed, while high-end special anti-corrosion products for deep sea and special chemical working conditions maintain high added value. The industry still faces challenges such as dependence on imported high-end raw materials and raw material price fluctuations.
Meanwhile, development opportunities are abundant. Urban underground utility tunnels, offshore wind power, hydrogen energy transmission and new energy projects continue to expand market space. The deep integration of industrial automation and digital technology helps enterprises optimize process parameters, improve product consistency and reduce comprehensive costs.
5. Future Prospect
In the future, the anti-corrosion coated steel pipe industry will continue to move towards high-end customization, green environmental protection and intelligent production. Enterprises will increase investment in technological research and development, break through bottlenecks in high-performance coating materials and process technology, and expand application scenarios in marine engineering, new energy and special equipment fields.
Industry concentration will further increase, and leading manufacturers will rely on technical advantages, stable quality and complete supporting services to expand market influence. Through industry-university-research cooperation and global layout, Chinese anti-corrosion coated steel pipe enterprises will continuously enhance international competitiveness, providing reliable material support for national infrastructure construction, energy security and global engineering projects.
