——Unveiling Efficient Welding Processes

Electric Resistance Welded (ERW) pipes: 

Cost-effective, high-precision solutions for oil and gas transmission and structural engineering. MTSCO offers high-standard ERW pipes with advanced heat treatment for superior weld quality and durability.

Electric resistance welded pipe (ERW) is a cost-effective choice in modern industrial pipeline systems, widely used in the fields of oil and gas transmission and structural engineering. The manufacturing principle utilizes the skin effect of high-frequency current to instantly heat the edge of the steel strip to a molten state, and fuse and connect it under the action of the extrusion roller. This process does not require the addition of filler metal, achieving atomic level bonding between the weld and the base metal.

Compared to seamless pipes, the biggest advantage of ERW welded pipes is their extremely high production efficiency and more competitive cost. Due to the use of cold-rolled or hot-rolled steel strips as raw materials, the thickness control of the pipe wall is extremely precise, and the surface smoothness is excellent. These characteristics make it an ideal solution for low and medium pressure fluid transportation, commonly found in the manufacturing of mechanical structures such as oil and gas pipelines, urban water supply networks, and scaffolding. It is worth noting that in order to ensure the mechanical properties of the weld area are consistent with the base metal, it is crucial to eliminate residual stresses generated during the welding process. Therefore, online heat treatment after welding is a key process for measuring product quality.

MTSCO is well aware that the core of welded pipe quality lies in weld seam control and heat treatment. Relying on the strategic factory Huxian, which has 35 years of manufacturing experience, we provide you with high standard industrial welded pipes. We adopt fully automatic welding technology to effectively solve the problem of non-circular welds in traditional large-diameter welded pipes.
