Global Oil and Gas Line Pipe Market Trends and Insights

LNG Export and Gas-Fired Power Pipeline Expansion

The oil and gas line pipe market benefits from the large volume of LNG capacity that reached final investment decision in 2025. The International Gas Union reported that 68.4 Mtpa of liquefaction capacity reached final investment decision during 2025, the highest annual approval volume in 6 years. The International Energy Agency stated that 345 bcm per year of sanctioned LNG capacity is scheduled to enter service through 2030. Each export project requires supporting transmission capacity beyond the terminal boundary, which creates demand for large-diameter pipe. These connections move gas from producing areas to processing sites and then to liquefaction terminals, so pipe demand extends beyond the export facility itself. The oil and gas line pipe market, therefore, benefits from both new terminal construction and the wider network upgrades that permit higher gas flows. The U.S. Energy Information Administration expects U.S. LNG exports to reach 17 Bcf/d in 2026 and 18.7 Bcf/d in 2027 as additional facilities begin operations. This buildout favors suppliers able to meet delivery schedules for high-pressure transmission projects.

Aging Transmission-Network Replacement

Replacement spending gives the oil and gas line pipe market a demand base that is less dependent on new field development. Northern Natural Gas reported a USD 5 billion Asset Modernization program covering 14,300 miles, of which 81% was installed before the 1968 federal pipeline safety standards. Its program includes USD 912 million for Vintage Pipeline Replacement during the next decade. Consumers Energy planned USD 215.3 million of gas infrastructure replacement investment for 2025. Such projects need careful planning because replacement work must protect service reliability on active networks. This makes the oil and gas line pipe market less exposed to short-term changes in drilling activity than a market driven only by greenfield projects. In Europe, Fluxys and Open Grid Europe commissioned the 110 km TENP III pipeline in July 2025 using hydrogen-ready steel. These programs increasingly require material qualification for possible hydrogen blending, which strengthens the role of technically capable suppliers.

Steel-Plate Cost and Margin Volatility

A steel plate is a major cost input for welded products in the oil and gas line pipe market. Fixed-price contracts can expose manufacturers to margin pressure when input costs rise after a contract is signed. This issue is most acute for large transmission projects because procurement and construction schedules can extend over several years. Higher plate costs can lead buyers to defer orders, change specifications, or seek lower-cost supply options. The effect can be stronger in regions that depend on imported plate or have limited mill capacity. Cost uncertainty, therefore, affects both project timing and supplier competition.

Other drivers and restraints analyzed in the detailed report include:

• Offshore and Deepwater Production Tie-Backs
• Associated-Gas Gathering and National Grid Investment
• Permitting and Long-Life Asset Uncertainty

Segment Analysis

Welded pipe accounted for 63.1% of the oil and gas line pipe market share in 2025 and is projected to expand at a 3.7% CAGR through 2031. Its position reflects a cost and availability advantage for large-diameter onshore projects. LNG feedgas corridors, national transmission grids, and gathering systems commonly require the sizes where welded pipe is most practical. Longitudinal and spiral submerged arc welded products are used for these high-volume applications. API 5L and ISO 3183 provide the material and performance frameworks that guide selection across welded and seamless products. High-grade welded pipe can meet demanding specifications for many high-pressure transmission projects. This supports continued demand where developers need large volumes with predictable delivery schedules.

Seamless pipe maintains a specialized role in offshore, deepwater, and sour-service installations. These projects require close control over wall thickness, pressure resistance, and corrosion performance. Vallourec supplied 18,000 tons of subsea seamless premium carbon steel line pipe for Petrobras’s Búzios 10 project in 2025, with an option for nearly 5,000 additional tons. Tenaris supplied pipe and thermal insulation coatings for the Trion ultra-deepwater project in Mexico, covering 16,000 tons for flowlines and risers at water depths of up to 2,300 m. Scientific research has found that hydrogen exposure can affect the integrity of pipeline girth welds and the behavior of X52 pipeline steel. This can maintain demand for pipe with verified performance in technically demanding service.

Geography Analysis

Asia-Pacific held 36.4% of the oil and gas line pipe market share in 2025 and is forecast to record a 4.8% CAGR through 2031. China is the region’s largest pipeline-demand center because of its national transmission expansion plan. The country plans 20,000 km of new long-distance oil and gas pipelines from 2026 through 2030. This work will take China’s network to 220,000 km. The second Sichuan-to-East Gas Transmission Pipeline began operations on its first section in 2025. The project uses X80 spiral and longitudinal submerged arc welded pipe across a 4,269 km route through 8 provincial regions.

North America is a major demand center for LNG-linked transmission capacity and replacement projects. The EIA expects U.S. LNG exports to increase to 17 Bcf/d in 2026 and 18.7 Bcf/d in 2027. This expansion requires pipelines that connect supply basins with liquefaction terminals. Northern Natural Gas’s modernization program reflects the separate need to replace older transmission assets. Canada joined LNG-exporting countries in 2025, adding another source of feedgas infrastructure demand. The oil and gas line pipe market in the region must also manage construction costs and the timing of permits. These factors can shift orders between years without removing the underlying need for new and replacement pipe.

Europe’s demand centers on replacement work and systems designed for future hydrogen transport. Germany’s Network Development Plan 2025 includes USD 23.22 billion in planned investment for 7,007 km of hydrogen infrastructure and 364 km of methane grid expansion. Fluxys and Open Grid Europe’s TENP III project shows how replacement projects can include a hydrogen-ready design. The Middle East and Africa maintain demand through production capacity programs and gas-gathering needs. The World Bank identified continuing infrastructure shortages in regions with material flaring volumes. South America is also developing new gas export infrastructure tied to Vaca Muerta resources. Regional demand depends on the pace of project approvals, financing, and cross-border infrastructure planning.
