Erw Tube Mill

 

ERW tube mill (Electric Resistance Welded Pipe, resistance welded pipe) is a steel pipe formed by heating the edge of the steel strip to the molten state through the resistance heat generated by the current and then welding it by pressure. Its characteristics and main advantages are as follows:

 

Efficient production process: It adopts continuous rolling and welding processes, featuring fast production speed and suitability for large-scale batch production.

Weld seam characteristics: The weld seam is a longitudinal straight seam. No filler material is required during the welding process, and the metal composition at the weld seam is basically the same as that of the base metal.

High dimensional accuracy: Through process control such as cold rolling and cold drawing, the tolerance of pipe diameter and wall thickness is small, and the surface finish is good.

Material adaptability: Mainly applicable to low-carbon steel, low-alloy steel and other materials, and products of different specifications (diameter, wall thickness) can be produced according to requirements.

 

 

 

1. Lower cost: High production efficiency and high raw material utilization rate. Compared with products like seamless steel pipes, its manufacturing cost is more competitive.

2. Stable mechanical properties: The weld strength is close to that of the base material, and the overall structure is uniform, which can meet the requirements of most pressure-bearing and structural support scenarios.

3. Wide application range: It is widely used in fields such as oil and gas transportation, water supply and drainage engineering, mechanical manufacturing, and building structures.

4. Convenient processing: It is easy to cut, bend and connect (such as welding, flange connection, etc.), facilitating subsequent construction and installation.

We have high precision machining centers and a relatively complete processing system which will insure to produce high quality round pipes, square pipes and rectangular pipes in high precision. This machine can be customized according to customer's requirements.

With mutual technology for ERW tube mill, our machines are stable, durable with high speed, high precision, which wins us very good reputation from our customers. Our tube mill line can be fully customized, please let us know your detailed requirements.
