Product Introduction: Electric Resistance Welded (ERW) Pipe
Electric Resistance Welded (ERW) pipes are a cornerstone within the pipeline industry, playing a critical role in various applications ranging from oil and gas transport to structural applications. The primary method of production involves resistance heating to create a solid-phase butt weld along the length of the pipe. In recent years, many manufacturers have upgraded to High Frequency Induction (HFI) heating. This advancement allows for better control over the welding process, ensuring consistent quality and reducing the incidence of defects.
Despite this evolution, the term "ERW pipe" remains the industry standard for describing these welded pipes, underscoring their importance and widespread use globally.
Key Specifications:
- Outside Diameter: Ranges from 88.9mm to 610mm (3” to 24”)
- Wall Thickness: Varies from 4.0mm to 12.7mm (0.157” to 0.5”)
- Length: Available in standard lengths of 3 to 12.2 meters (10' to 40')
- Grades: Conforms to API 5L GR B to GRX80
- Standards: Manufactured in accordance with API 5L, ASTM A671, ASME A672, ASME A691, ISO 3183, and DIN EN10208
