Understanding SS 304 ERW Pipe and Its Manufacturing Process
What is Stainless Steel 304 ERW Pipe?
304 ERW Pipe is a type of stainless steel pipe that is manufactured using Electric Resistance Welding (ERW) technology. This process involves fusing metal without using filler material, resulting in a strong, seamless bond. The SS 304 ERW Pipe is known for its high tensile strength, excellent corrosion resistance, and smooth surface finish, making it ideal for structural and fluid transportation applications.
How is SS 304 ERW Pipe Manufactured?
The manufacturing of Stainless Steel 304 ERW Pipe involves the following steps:
- Raw Material Selection: High-quality SS 304 stainless steel coils are used as the base material.
- Forming Process: The steel coil is passed through a series of rollers to form a cylindrical shape.
- Electric Resistance Welding (ERW): An electric current is applied to the edges of the pipe, generating heat that fuses the metal together.
- Sizing and Straightening: The welded pipe is passed through sizing rollers to achieve the desired dimensions.
- Heat Treatment & Surface Finishing: To enhance durability and corrosion resistance, the pipe undergoes heat treatment and is polished for a smooth finish.
- Testing and Inspection: 304 ERW Pipe is subjected to rigorous quality tests, including hydrostatic, ultrasonic, and non-destructive testing, ensuring structural integrity.
Key Benefits of Using SS 304 ERW Pipe in Construction & Engineering
