1. Overview of the Global JCOE Steel Pipe Industry
The upgrading of global energy infrastructure, the renovation of aging pipelines, the construction of transnational energy corridors, and the large-scale implementation of marine engineering projects continue to drive the rigid demand for large-diameter, high-pressure pipelines. Compared with traditional pipe manufacturing processes, the JCOE progressive submerged arc welding process has better adaptability to large-diameter, thick-walled, and high-grade steel pipes, and can meet complex service conditions such as high pressure, low temperature, acidic media, and long-distance transportation. It has now become the mainstream manufacturing solution for international oil and gas trunk pipelines, large-scale municipal pipeline networks, and high-end steel structure projects.
According to PW Consulting statistics, the global JCOE steel pipe market reached US$8.08 billion in 2025 , and is expected to grow to US$8.43 billion in 2026 , and reach US$10.89 billion by 2032, with a compound annual growth rate (CAGR) of 4.35% from 2025 to 2032 , showing a steady growth trend in the industry as a whole.
The core drivers of industry growth are concentrated in three aspects: First, the accelerated construction of global long-distance natural gas pipelines is continuously releasing demand for high-pressure, large-diameter trunk pipes; second, the upgrading and renovation of existing pipeline networks in various countries is driving replacement demand; and third, emerging scenarios such as marine engineering, hydrogen energy transportation, CCUS carbon sequestration, and high-end industrial fluid transportation are continuously expanding the application boundaries of JCOE pipes. At the same time, international engineering requirements for pipe dimensional accuracy, weld integrity, material toughness, corrosion resistance, full-process traceability, and special project certifications are constantly being upgraded, and the industry is gradually shifting from "capacity competition" to "competition in process quality and system manufacturing capabilities."
2. Analysis of the Regional Pattern of the Global Market
The global JCOE steel pipe market exhibits a significant regional concentration, with the Asia-Pacific region maintaining its position as the world's largest consumer and production market thanks to its well-developed steel industry system, large-scale pipeline equipment clusters, and continuous infrastructure investment. The global regional market share distribution in 2025 is as follows: Asia-Pacific 45% (market size US$3.64 billion), North America 18%, Middle East and Africa 16%, Europe 15%, and Latin America 6%.
The core competitiveness of the Asia-Pacific market comes from China. China has a complete steelmaking system, mature JCOE pipe manufacturing production lines, large-scale industrial clusters, and export-oriented manufacturing enterprises. It can not only meet the needs of domestic energy pipelines, urban infrastructure, wind power steel structures, and high-speed railway bridge projects, but also participate deeply in global energy project bidding and overseas infrastructure supply. It is the core capacity support region of the global JCOE steel pipe supply chain.
Unlike other regions, China's JCOE industry possesses both domestic demand absorption capacity and international delivery capability, enabling it to adapt to the standard systems and operating conditions of different regions such as the Middle East, Southeast Asia, Latin America, and Europe. It has irreplaceable locational and industrial advantages in the global pipeline engineering supply chain.
3 JCOE process technology characteristics and engineering value
JCOE process is a progressive forming technology specifically developed for large-diameter straight seam submerged arc welded pipes. The core process includes: steel plate pretreatment—edge milling and pre-bending—J-shaped, C-shaped, and O-shaped progressive forming—precise seam pre-welding—internal and external submerged arc welding—mechanical diameter expansion—precision dimensional correction—non-destructive testing and performance evaluation. Unlike one-time pressing forming processes, JCOE progressive forming effectively releases forming stress and avoids quality problems such as localized deformation, edge misalignment, and out-of-tolerance ovality.
The core technological advantages of this process are reflected in two aspects: First, it is flexible in specification adaptation, and can stably produce large-diameter, thick-walled, and long-length pipes to meet the customized wall thickness and pipe diameter requirements of engineering projects; Second, it has high forming accuracy and low residual stress. Combined with mechanical diameter expansion and automated testing system, it can ensure the consistency of steel pipe dimensions and the stability of welds, and meet the stringent service standards of high-pressure long-distance pipelines.
Current mainstream technological iterations in the industry focus on fully automated ultrasonic testing and precision mechanical diameter expansion. These two technologies can significantly improve pipe dimensional accuracy, weld integrity, and batch production consistency, becoming core technical indicators for supplier selection in high-end engineering projects. Modern pipeline engineering procurement no longer focuses solely on forming methods but also emphasizes integrated system manufacturing capabilities encompassing forming, welding, diameter expansion, testing, traceability, and documentation .
4. Downstream application structure and operating condition requirements
In terms of application structure, oil and gas transportation remains the core downstream application area for JCOE steel pipes . By 2025, the global oil and gas pipeline application will account for 65% , corresponding to a market size of US$5.25 billion; marine engineering will account for 18%, water conservancy infrastructure for 12%, and chemical and industrial fluid processing for 5%.
Long-distance oil and gas pipelines operate under complex conditions, placing extremely high demands on the comprehensive performance of pipe materials. These requirements extend beyond stable pipe diameter, wall thickness, and straightness accuracy; they must also meet comprehensive performance requirements in areas such as high pressure bearing capacity, temperature fluctuations, media corrosion, alternating loads, low-temperature toughness, and crack resistance under acidic conditions. Therefore, pipe material selection must be based on a comprehensive assessment of multiple parameters, including design pressure, operating temperature, transported medium, fracture toughness, hydrogen sulfide/carbon dioxide corrosion environment, cyclic loads, and installation conditions, rather than solely relying on steel grade strength.
In emerging fields, hydrogen energy transportation and CCUS carbon sequestration pipelines place higher demands on pipe materials for hydrogen embrittlement resistance, media corrosion resistance, high toughness, and high stability, which is driving the continuous growth in demand for high-end X80 and above high-strength JCOE pipe materials, becoming a new growth track in the industry.
5. Analysis of the Market Demand Structure of Mainstream Steel Grades
From the perspective of global steel grade demand structure, X70 and X80 are currently the absolute mainstream steel grades for long-distance oil and gas pipelines. In the global JCOE steel pipe market in 2025, X80 steel grade will account for 45% , X70 steel grade will account for 35% , X100 ultra-high grade steel grade will account for 10%, and other conventional structural steel grades will account for a total of 10%.
The widespread application of X70 and X80 steel grades represents the industry's optimal balance between structural strength, pressure bearing capacity, weldability, manufacturing cost, and engineering applicability. However, in practical engineering applications, high steel grade does not equate to high adaptability. The material failure mechanisms and fracture control requirements for emerging operating conditions such as hydrogen energy and carbon dioxide transportation differ significantly from those of traditional oil and gas pipelines, necessitating targeted material selection, welding process qualification, and operating condition adaptation verification.
6. Quality Control System: A Core Competitive Barrier in the Industry
As pipeline engineering conditions become increasingly demanding, end-to-end quality control has become a key barrier differentiating JCOE steel pipe manufacturers from their core strengths. The production processes of large-diameter LSAW steel pipes are highly coupled; deviations in any环节 (link/step), such as the properties of the steel plate raw materials, the precision of the plate edge processing, forming parameters, welding heat input, diameter expansion, and testing accuracy, will be transmitted to the final product, affecting the pipeline's operational safety.
A modern JCOE manufacturing system must achieve closed-loop management throughout the entire process, encompassing incoming raw material inspection, precision edge machining, automated forming, submerged arc welding, controllable mechanical diameter expansion, online non-destructive testing, dimensional precision verification, hydrostatic testing, mechanical property sampling, and full-chain traceability and archiving. International buyers have gradually abandoned the purely capacity-oriented evaluation model, focusing instead on assessing a company's integrated manufacturing system, automated testing capabilities, process stability, and project-customized certification capabilities.
