TJ Wasungen supplies a wide range of longitudinal welded pipe configurations designed for different industrial and construction requirements.
Our product range includes:
Longitudinal welded pipes are widely used in construction, infrastructure, manufacturing, and industrial engineering projects. Their strong structural performance and cost efficiency make them ideal for large-scale commercial and industrial applications.
Common applications include:
Structural steel frameworks
Building construction and scaffolding
Water, gas, and fluid transportation
Agricultural irrigation systems
Mechanical and industrial fabrication
Oil and gas support structures
Furniture and steel fabrication industries
Fencing, handrails, and utility poles
These pipes are also commonly used in warehouses, bridges, factories, stadiums, and infrastructure development projects where strength and durability are essential.
Our longitudinal welded pipes are manufactured using high-quality steel coils or strips processed through advanced forming and welding systems. The steel strip is formed into a cylindrical shape and welded along the longitudinal seam using high-precision welding technology to ensure strong bonding and structural integrity.
After welding, the pipes undergo sizing, straightening, cutting, and surface finishing processes to achieve precise dimensions and consistent quality. Depending on customer requirements, additional galvanizing, coating, or anti-corrosion treatments can also be applied.
Each production batch undergoes strict quality inspections, including:
Weld seam inspection
Dimensional tolerance checks
Hydrostatic pressure testing
Surface quality inspection
Mechanical property testing
Corrosion resistance evaluation
Our manufacturing facilities maintain strict quality control systems to ensure compliance with international industrial standards.
