Increase in the Importance of Welded Steel Tube in Oil & Gas Industry

The oil and gas sector heavily relies on welded steel tubes owing to their high tensile strength, durability, and resistance to corrosion, which are critical in the challenging environments of oil exploration, production, and transportation. Welded steel tubes are used to construct pipelines that transport crude oil, natural gas, and other liquids over long distances. The strength and resistance of steel tubes to high pressures make them ideal for these applications. They can withstand the extreme pressures and environmental conditions encountered in both land and subsea pipelines. There is an increase in investment in the construction and expansion of oil and gas pipelines across the globe. For instance, in January 2025, Canada's Alberta government partnered with Enbridge Inc., a US-based pipeline company, to expand the province's oil and gas pipeline capacity. Alberta government exports more than 4.3 million barrels per day of crude oil to the US. Further, in July 2024, Enbridge Inc., an energy delivery company in Canada, planned to invest US$ 700 million in Mexico to build new crude oil and natural gas pipelines. The crude oil and gas pipeline, named the Canyon Oil Pipeline System, will have a capacity of 200,000 barrels per day. Welded steel tubes play a vital role in the oil and gas industry, particularly in the construction of pipelines that transport crude oil, natural gas, and other liquids over long distances. These pipes must withstand high internal pressures, mechanical stresses, and corrosive environments. High-quality carbon or alloy steel welded tubes are designed to meet these demanding requirements effectively.

Further, the governments of France and Germany announced their plans to initiate a 100-km hydrogen pipeline project in 2024. As a part of this project, GRTGaz, a prime gas supplier in France, is set to authorize the installation of a hydrogen pipeline linking France and Germany, marking a substantial step toward decarbonizing heavy industries in both countries. In addition, in 2023, the governments of Germany and Italy joined forces to form a projected gas pipeline. The proposed pipeline is a 3,300 km project and is anticipated to incorporate four European transmission system operators, including Trans Austria Gasleitung, Snam, Bayernets, and Gas Connect Austria, in Germany.

Countries such as the US, China, India, Vietnam, and South Korea are showcasing a massive demand for crude oil owing to continuous developments in their manufacturing sectors, supported by favorable financial landscape and government policies and a surge in investments in the oil & gas sector. The share of shale production is anticipated to increase from ~23% of total gas production in 2010 to ~49% by 2035 in the country.

Key Findings of Welded Steel Tube Market Study:

Asia Pacific accounted for the largest share of the welded steel tube market in 2024, owing to the increasing demand for welded steel tubes in the growing construction sector. The construction sector in Asia Pacific was valued at US$ 4.4 trillion in 2023, representing 46% of the global construction sector output. The increase in private and public sector investments in infrastructure developments drives the construction sector in Asia Pacific. Welded steel tubes are widely used in building frameworks, including columns, beams, and trusses, due to their high load-bearing capacity. Welded steel tubes are used in the construction of bridges, road barriers, and other infrastructures, resisting stress and environmental factors. Further, according to the Asian Development Bank (ADB), investments in the infrastructure development sector in Asia Pacific will reach US$1.7 trillion per year by 2030.

In Asia Pacific, China held the largest market share in 2023, owing to the increasing investment in the energy and power sector. According to the International Energy Agency Report, in 2023, China's international investments in the renewable clean energy sector reached US$ 100 billion, and they continue increasing rapidly. The energy and power sector requires high-strength welded steel tubes for energy infrastructure developments. The Government of India launched a comprehensive planned investment of US$ 109.50 billion to enhance the country's energy and power infrastructure sector. The Ministry of Power in India aims to strengthen the national power grid and increase energy security in the country. India's welded steel tube market is rapidly expanding due to significant investments in the automotive and industrial sectors. Mercedes Benz planned to invest more than US$ 360.14 million in Maharashtra, India. In March 2024, Tata Motors Group has signed agreement to facilitate the Memorandum of Understanding (MoU) with the Government of Tamil Nadu to set-up of a vehicle manufacturing facility in the state. The MoU made an investment of US$ 1,081.6 million for the next 5 years.

Based on steel grades, the welded steel tube market is segmented into carbon base grades, boron grades, alloy grades, HSLA, and AHSS. Among these, the carbon base grades segment accounted for the largest share in 2023, owing to the increasing demand for automotive and industrial applications. According to the German Council on Foreign Relations (DGAP), the global automotive industry was valued at US$ 4 trillion in 2023 and is projected to reach US$ 6 trillion by 2030. Based on applications, the welded steel tube market is segmented into exhaust, automotive, appliances, medical devices, HVAC, burner, and others. Among these, the automotive applications segment accounted for the largest share in 2023, owing to the increasing investment in electric vehicle plant production with government funding and initiatives. For instance, in January 2025, BYD Ltd. planned to open an EV plant in Indonesia with 150,000 vehicle production capacity. Based on type, the welded steel tube market is segmented into electric resistance welded (ERW), longitudinal submerged arc welding (LSAW), and spiral welded steel pipe (SSAW pipe). Among these, the electric resistance welded (ERW) segment held the largest market share in 2023, owing to the increasing demand from industrial machinery manufacturing and automotive sectors.

Based on coating type, the market is segmented into clear coat and non-coated. The non-coated segment accounted for a larger share in 2023, owing to the rising demand in the energy and oil and gas sectors. The oil and gas sector uses non-coated welded steel tubes owing to higher strength, durability, and corrosion resistance.
