A seam pipe, also known as a welded pipe, is a type of pipe that is manufactured by rolling a flat steel plate or strip into a cylindrical shape and then welding the edges together. The welding process creates a visible seam along the length of the pipe, which distinguishes it from seamless pipes, which are manufactured without a welded joint.
Types of Seam Pipes
Electric Resistance Welded (ERW) Pipe
Made by rolling steel and welding it longitudinally using electric resistance. Commonly used in water pipelines, scaffolding, and structural applications.
Longitudinal Submerged Arc Welded (LSAW) Pipe
Formed by bending steel plates and welding them along a single seam. Used in high-pressure applications such as oil and gas transportation.
Spiral Submerged Arc Welded (SSAW) Pipe
Manufactured by forming steel coils into a spiral shape and welding the edges together. Commonly used in large-diameter pipelines for water, oil, and gas transmission.
Advantages of Seam Pipes
Cost-effective compared to seamless pipes due to lower manufacturing costs.
Available in large diameters, making them suitable for various applications.
Customizable wall thickness and length, depending on project requirements.
Widely used in industries such as construction, water transmission, and oil & gas pipelines.
Common Applications of Seam Pipes
Oil and gas transportation pipelines
Water supply systems
Structural and construction frameworks
Piling applications in foundation engineering
While seam pipes are widely used in different industries, their suitability depends on the required strength, pressure capacity, and environmental conditions.
