III. Existing Problems in the Domestic LSAW Steel Pipe Manufacturing Industry
3.1 High capital investment threshold and large barriers to entry in the industry
JCOE requires huge investments in equipment for forming, submerged arc welding, online non-destructive testing, and hydrostatic testing. The factory, testing laboratory, and qualification certification processes are lengthy, making it extremely difficult for new companies to enter the large-diameter LSAW market. The industry is characterized by a clear concentration of leading companies.
3.2 Fluctuations in raw material prices squeeze corporate profits
Steel plates account for over 70% of the production cost of pipes, and steel prices fluctuate cyclically. Since steel pipe manufacturers purchase steel plates independently, the risk of rising steel prices is borne by the manufacturers, leading to significant fluctuations in their profitability.
3.3 The projects are highly customized and have strong order cycles.
Pipeline projects are primarily conducted through engineering bidding, and project commencement is influenced by energy infrastructure investment, resulting in a clear cyclical nature of orders. Different projects have customized requirements for steel grade, wall thickness, flaw detection, and operating conditions, making it difficult to achieve fully standardized mass production.
3.4 High-end special pipe materials have high technological barriers
The market for standard X70/X80 pipeline pipes is highly competitive; however, high-value-added pipes for applications such as gas storage, deep-sea applications, acidic media applications, and applications requiring high deformation resistance have high R&D barriers and are dominated by leading companies, making it difficult for most companies in the industry to achieve stable mass production.
3.5 Risks related to process control, such as weld defects and residual stress
The control of residual stress during LSAW steel pipe forming, welding quality, and diameter expansion requires high standards for process and equipment operation and maintenance. If process control is not in place, non-destructive testing failures will result in high rework costs.
IV. Market Trends and Future Development Trends
4.1 Continued energy infrastructure investment drives up the value of high-end specialty pipes
Domestic long-distance oil and gas pipelines, underground gas storage facilities, CCUS (Gas Concentration Protection System), and hydrogen energy transmission pipelines continue to be planned and implemented, leading to sustained growth in demand for high-grade steel (X80 and above), acid-resistant, low-temperature resistant, and hydrogen embrittlement-resistant special pipelines. Competition in the conventional pipeline market is becoming increasingly fierce, while high-end special pipelines, with their higher added value, are a key area of competition for leading companies.
4.2 Widespread adoption of digital and intelligent pipe manufacturing production lines
The industry is accelerating the deployment of MES production management systems, automated welding, online non-destructive testing, and process simulation. Digital control reduces welding defect rates, stabilizes dimensional accuracy, and shortens project delivery cycles. Intelligent capabilities will become a core competitive indicator for manufacturing enterprises.
4.3 Integrated turnkey solutions are becoming a customer preference.
Owners and EPC contractors tend to prefer suppliers that can provide a variety of pipe materials, matching beveling, corrosion protection, and integrated testing services. Companies that only produce LSAW pipes are less competitive in multi-category packaged bidding projects, while full-category pipe manufacturers like Haiganwei will gain more project opportunities.
4.4 Export market growth highlights the value of international certification
The "Belt and Road" initiative is driving the export of LSAW steel pipes through overseas oil and gas and energy infrastructure projects. Domestic steel pipe manufacturers with API, PED, and EAC international certifications and overseas project experience have great potential for overseas order growth.
4.5 Requirements for green and low-carbon manufacturing continue to rise.
Under the dual-carbon development model, energy consumption control in pipe manufacturing and corrosion protection processes is becoming increasingly stringent. Low-energy molding processes, waste heat recovery, environmentally friendly anti-corrosion coatings, and green factory certifications will become important factors influencing future bidding decisions.
V. Summary of Future Industry Competition
Future industry competition will diverge into two main tracks: one is the high-end specialty pipe sector, encompassing national-level trunk pipelines, gas storage facilities, and deep-sea pipelines, where competition will focus on cutting-edge R&D, extreme-condition pipe technology, and significant engineering achievements; the other is the regional pipeline network, refining and chemical, steel structure, and overseas small-to-medium-sized projects sector, where competition will focus on integrated supply of multiple product categories, delivery efficiency, and overall cost. When selecting suppliers, owners and EPC contractors should comprehensively evaluate projects based on their specific conditions, pipe product mix, and project scale, rather than solely relying on production capacity and price as the sole criteria. With the construction of domestic energy pipeline networks and the expansion of overseas infrastructure, the domestic LSAW manufacturing industry continues to upgrade towards high-grade steel, special-condition pipes, and green intelligent manufacturing.
