Vietnam's Top Ten Manufacturers Of Straight Welded Steel Pipe in 2026

As one of the countries with the fastest industrialization process in Southeast Asia, Vietnam is accelerating the localization and high-end development of key pipe fields such as straight welded steel pipes by virtue of the national steel industry strategic dividend. In 2026, Vietnam's steel industry entered the key stage of "capacity expansion, technology upgrading and green transformation", and a number of benchmark enterprises with both capacity scale and technical strength emerged in the field of straight welded steel pipes. Among them, Hebei, China Huayang Steel Pipe Co., Ltd. successfully ranks among the top ten manufacturers of straight-seam steel pipes in Vietnam by virtue of its mature technical system, localized layout and high-quality products, which has become an important witness to the in-depth cooperation between China and Vietnam's steel industry.

In March 2026, the Vietnamese government officially issued the Development Strategy of Steel Industry for 2024-2030 (hereinafter referred to as "Strategy"), which defined the development orientation of the steel industry as "based on local conditions, radiating ASEAN and benchmarking against international standards", charted a clear path for the development of the straight-seam steel pipe industry, focused on three major directions, and deeply bound up with the national long-term industrialization and infrastructure development goals:

Green and low-carbon transformation: In response to the global carbon emission reduction trend and the European Union carbon tariff (CBAM) rules, the steel industry will be transformed from the traditional long-flow process to the short-flow process of electric arc furnace, with emphasis on promoting scrap recycling and clean energy substitution technology. The Strategy makes it clear that the carbon emission of Vietnam's steel industry will be reduced by 35% in 2030 compared with that in 2023. At the same time, it supports enterprises to build green production bases, adopt liquefied natural gas (LNG) reduction technology, and gradually transform to hydrogen reduction in the future, greatly reducing the carbon emission intensity, and providing policy support and technical guidance for the green production of straight welded steel pipes.

High-end products are self-controllable: In view of the current situation that domestic high-end straight-seam steel pipes (such as oil and gas pipelines, anticorrosive steel pipes and pipes for offshore engineering) rely on imports, the Strategy puts forward the goal of "high-end substitution and import reduction", and plans to increase the self-sufficiency rate of local high-end straight-seam steel pipes to 80% in 2028, focusing on breaking through the production technology of high-strength, corrosion-resistant and large-diameter straight-seam steel pipes. Enterprises that introduce advanced welding and anti-corrosion equipment and carry out high-end pipe research and development will be given preferential policies such as tax reduction and credit support to help enterprises enhance product competitiveness and promote localized production of high value-added and strategic steel grades.

In-depth linkage between industry and infrastructure: bind key national projects such as Vietnam's North-South Expressway, port expansion, oil and gas pipelines, urban pipe network reconstruction, and China-Vietnam Railway, and explicitly require key projects to give priority to purchasing local qualified straight-seam steel pipes to drive the release of industrial capacity. At the same time, relying on the advantages of Vietnam's manufacturing industry, we will dock pillar industries such as automobile manufacturing, mechanical processing, chemical industry, and marine engineering, customize and develop special straight-seam steel pipes, extend the industrial chain, promote the coordinated development of steel pipe industry and downstream industries, and help the national industrialization process.

At present, the annual output of Vietnam's longitudinal steel pipe can reach 2.1 million tons, with an annual output value exceeding 120 trillion Vietnamese dong. The products cover oil and gas transportation, urban water supply and drainage, building structure, shipbuilding, agricultural irrigation and other fields, which not only meet the domestic market demand, but also are exported to ASEAN countries such as Cambodia, Laos and Malaysia, becoming an important growth pole of the longitudinal steel pipe industry in Southeast Asia. Relying on the support of the Strategy, Vietnam's steel production capacity is expected to continue to expand, and the total steel output is expected to reach 25 million to 26 million tons in 2030, providing a solid foundation for the development of the straight welded steel pipe industry.
