Product Specification
ERW (Electric Resistance Welding) carbon steel pipes are manufactured using the following key steps to ensure their high quality and performance
Products Description
1.Material Selection: High-quality carbon steel coils are carefully chosen as the raw materials to guarantee the strength and durability of the pipes.
2.Plate Shearing: The carbon steel coils are precisely cut into the required sizes, preparing them for further processing.
3.Roll Forming: Through pre-bending and roll forming, the sheared plates are shaped into pipes with a circular cross-section.
4.Electric Resistance Welding: Contact is established at the edges of the pipe, and through the application of current, heat, and pressure, the contacting surfaces are melted and fused together, creating the weld seam.
5.Post-processing: The weld seam undergoes external and internal treatments to eliminate irregularities and internal stresses, ensuring the smoothness and consistency of the pipes.
6.Testing and Quality Control: Various non-destructive and destructive tests, such as ultrasonic testing, eddy current testing, and tensile testing, are conducted to ensure the pipes meet the required quality standards.
Product Features and Benefits
1.High Strength: The pipes are manufactured using high-quality carbon steel materials, providing excellent strength and durability to withstand high pressure and temperature conditions.
2.Superior Welding Performance: The electric resistance welding process ensures superior welding performance of the pipes, resulting in high weld seam strength and minimal issues like cracks and leakage.
3.Excellent Corrosion Resistance: With the application of corrosion-resistant coatings or galvanization, the pipes exhibit enhanced resistance to corrosion, making them suitable for petroleum, natural gas, and water transportation.
4.Versatile Applications: They find extensive applications in the transportation of petroleum, natural gas, and water. They are also ideal for refineries, boiler and machinery manufacturers, structural constructions, drilling operations, shipbuilding, and more.
5.Customized Design and Processing: We offer customized design and processing services based on customer requirements and provided drawings, ensuring that the pipes meet the specific needs of each project.
