ERW Steel Pipe China Manufacturer
ERW Steel Pipe, also known as straight seam electric resistance welded pipe, is a steel pipe that uses high-frequency resistance heating to melt the edge of the strip and press the welded joint.
ERW Steel Pipe is welded from steel plates or steel strips, and the raw materials can be carbon steel, alloy steel or stainless steel, etc.
It is mainly used to transport gas and liquid objects such as oil and natural gas, meeting various high and low pressure requirements. It is widely used in oil, natural gas, chemical industry, water transportation and other fields. It is also a structural pipe, such as the pillar of bridges and buildings.

ERW Steel Pipe Production Process
1. Material preparation: Select high-quality steel coils and cut them into steel strips of appropriate width according to needs.
2. Forming: The steel strip is gradually formed into a round tube shape through a series of rollers.
3. High-frequency heating: Use high-frequency current to heat the edge of the steel strip to make it molten.
4. Extrusion welding: The edges of the molten steel strip are squeezed together by extrusion rollers in a heated state to form a weld.
5. Weld treatment: After welding, the weld is subjected to online heat treatment (such as weld annealing) and non-destructive testing to ensure the quality and uniformity of the weld.
6. Sizing and straightening: The diameter of the pipe is adjusted by sizing rollers, and the steel pipe is straightened to ensure dimensional accuracy and straightness.
7. Cutting and end processing: Cut the formed steel pipe into the required length and perform end processing, such as chamfering or threading.
8. Inspection and testing: The steel pipe is subjected to dimensional inspection, mechanical property test and pressure test, etc. to ensure that the product meets relevant standards and requirements.
