Oil and Gas Line Pipe Market Size & Share Analysis - Growth Trends and Forecast (2026 - 2031)

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^{[1]International Gas Union, “World LNG Report 2026,” International Gas Union, igu.org}. 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^{[2]U.S. Energy Information Administration, “U.S. Natural Gas Exports to Grow Nearly 30% by 2027 as LNG Facilities Ramp Up,” Today in Energy, eia.gov}. 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^{[3]Northern Natural Gas, “Asset Modernization Report 2025,” Northern Natural Gas, northernnaturalgas.com}. 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^{[4]Consumers Energy, “Gas Enhanced Infrastructure Replacement Program, 2025 Planning Report,” Michigan Public Service Commission Filing, openmpsc.com}. 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.

Offshore and Deepwater Production Tie-Backs

Offshore tiebacks support demand for seamless pipe and advanced coating systems within the oil and gas line pipe market. Operators use tiebacks to connect new subsea wells to existing production facilities, which can lower development costs and shorten the time before production. The approach reduces the need for a separate offshore host facility, but it also places high requirements on pipe integrity and insulation. Vallourec received orders from ExxonMobil Guyana in May 2026 for more than 145 km of line pipe, totaling nearly 40,000 metric tons, for the Hammerhead and Longtail projects. The order included 90 km of pipe with resin-based insulation for subsea use. Tenaris also announced supply for Sakarya Phase 3 in Türkiye, including 22,700 tons of seamless pipe and 87,800 tons of welded pipe for offshore flowlines and export infrastructure. The oil and gas line pipe market is supported by projects that require both premium seamless products for subsea sections and welded products for export lines. These projects favor suppliers that can provide both high-grade pipe and specialized insulation or coatings.

Associated-Gas Gathering and National Grid Investment

The oil and gas line pipe market also gains support from efforts to capture gas that would otherwise be flared and from national grid expansion plans. The World Bank reported that global gas flaring reached 167 billion cubic meters in 2025, the highest level since 2019. It estimated the lost value of flared gas at USD 54 billion and stated that eliminating routine flaring would require USD 70 billion to USD 100 billion of upfront investment, including gathering systems and pipelines. Gathering systems can provide the physical link between wells, processing facilities, and sales pipelines. This makes the oil and gas line pipe market relevant to compliance programs as well as to conventional gas transportation investment. China plans to expand its long-distance oil and gas pipeline network by 20,000 km during 2026 through 2030, taking the network to 220,000 km. China also plans to increase LNG receiving capacity to 200 million tonnes per year. These projects connect public policy objectives with long-term demand for gathering lines and transmission systems.

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.

Permitting and Long-Life Asset Uncertainty

Permitting and financing risks can slow pipeline projects even when the underlying gas demand is clear. Environmental reviews, community concerns, and legal challenges can delay construction in North America and Europe. Developers may order pipe for early construction phases while postponing later sections until permits are secure. This pattern can make order intake uneven for the oil and gas line pipe market. Concerns about the useful life of fossil fuel infrastructure can also make capital providers more selective. Hydrogen conversion plans may reduce this risk, but uncertainty about material performance remains an obstacle in some cases.

Segment Analysis

By Type: Welded Pipe Led Large-Diameter Onshore Demand While Seamless Pipe Served Offshore Applications

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 EUR 20.1 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.
