Top 10 LSAW Steel Pipe Manufacturers in 2026 (2025 Review)

Introduction: Why LSAW steel pipes play an important role in global infrastructure (2026)

LSAW (Longitudinal Submerged Arc Welded) steel pipes play a pivotal role in global energy and infrastructure development, serving as the backbone for oil and gas transmission, water supply systems, and large-scale construction projects. As we enter 2026, the global infrastructure industry is experiencing a major recovery and expansion, driven by the increase in energy demands and the modernization of government investments channels. Driven by the increasing energy demand and infrastructure upgrading of emerging economies, the market of longitudinal submerged arc welded pipe is expected to grow by 2.3% CAGR by 2026.

The unique manufacturing process of LSAW pipes—using longitudinal submerged arc welding on thick steel plates—makes them ideal for high-pressure applications and large-diameter requirements. Compared to SSAW (spiral submerged arc welded) and ERW (electric resistance welded) pipes, LSAW pipes offer superior strength, better dimensional accuracy, and enhanced pressure-bearing capacity, making them the preferred choice for critical infrastructure projects where safety and reliability are paramount.

What is an LSAW steel pipe?

Definition and manufacturing methods

LSAW steel pipe is manufactured by longitudinal submerged arc welding process, in which steel plates is cold-formed into a cylinder by JCOE or UOE forming processes before double-sided submerged arc welding. This method ensures excellent welding quality and dimensional accuracy. Compared with spiral welding, longitudinal welding provides better strength characteristics.

Typical size range and standard

LSAW pipes is characterized by its large diameter capacity, usually ranging from 406 mm to 1620 mm (16 inches to 64 inches), wall thicknesses ranging from 6 mm to 60 mm, and lengths up to 18 meters. These pipelines conform to major international standards, including API 5L PSL 1/PSL 2, ASTM A 252, ASTM A 671/a 672, EN 10219 and EN 10217, which ensure global compatibility and quality assurance.

Main Applications programs

LSAW steel pipes are mainly used in:

• Oil and gas pipelines (long distance and high pressure applications)
• Water supply and sewerage systems.
• Structural applications of buildings and infrastructure.
• Offshore engineering and ocean engineering.
• Power stations and industrial piping systems.

Comparison Table: LSAW Top Manufacturers

LSAW vs SSAW vs ERW: which one should you choose?

Structural Differences

• LSAW (Longitudinal Submerged Arc Welded): Manufactured by bending steel plates into cylindrical shapes and welding along the longitudinal seam using submerged arc welding. It is characterized by a straight weld parallel to the pipeline axis, which provides excellent dimensional accuracy and high strength.
• SSAW (Spiral Submerged Arc Welded): Produced by spiral winding steel strips and welding along the spiral seam. It provides flexibility in diameter production using the same width of steel strip, but it has longer welding lengths and relatively poor geometric dimension accuracy.
• ERW (Electric Resistance Welded): Created by cold-forming steel sheets into cylindrical shapes and welding the seam with high-frequency current. Straight seams with high dimensional accuracy and smooth surface, but limited to small diameters and thin walls.

Pressure bearing Capacity

LSAW pipes is outstanding in high pressure applications because of its thick walls (up to 60 mm) and excellent welding quality. They can withstand pressures as high as 12 MPa or higher, making them ideal choice for long-distance oil and gas transportation. SSAW pipes are suitable for medium pressure applications, while ERW pipes are usually used for low and medium pressure requirements.

Cost and performance

Due to the complicated manufacturing process and higher material requirements, LSAW pipes have the highest production cost, but provide the best performance in demanding applications. SSAW pipe provides an economical and effective solution for large diameter demand with medium pressure. For small and medium diameter applications with low pressure requirements, ERW tube is the most economical choice.

Project suitability

• Choose LSAW for: High-pressure oil and gas pipelines, offshore projects, critical infrastructure, and applications requiring maximum reliability and safety.
• Choose SSAW for: water transmission, sewage treatment systems, low-pressure fluid transportation and large-diameter projects that are sensitive to cost.
• Choose ERW for: urban gas distribution, water supply networks, structural applications and projects with budgetary constraints.

How to choose reliable LSAW steel pipe manufacturer?

Authentication and detection

When selecting a manufacturer, check whether it meets the international standards, such as API 5L PSL 1/PSL 2, ISO 9001 and relevant regional standards. Ensure the manufacturer provides comprehensive mill test certificates (MTC) with chemical composition analysis, mechanical properties testing, and non-destructive testing results including ultrasonic, radiographic, and hydrostatic tests.

Match of production range

Evaluate the manufacturer’s ability to meet your specific project requirements, including diameter range (406 mm -1620 mm), wall thickness (6 mm -60 mm) and length requirements (up to 18 meters). Consider whether the LSAW pipe manufacturer can produce the required steel grades (API 5L Grade B through x 80) and whether they offer customization options for special applications.

Painting and logistics capability

Evaluate the manufacturer’s ability of anti-corrosion coating, including 3 LPE, FBE, coal tar epoxy and other protective coatings. Verify their logistics network and ability to handle large-volume shipments, including packaging standards, transportation methods, and delivery timelines. Make sure that they have experience in handling international transport and customs documents.

Communication and Documentation

Choose manufacturers with responsive technical support teams that can provide engineering consulting, project documents and after-sales service. Find companies that provide comprehensive documents, including material certificates, inspection reports and traceability records. Evaluate their ability to communicate effectively in the language and time zone you like.
