ASTM A671/A671M Standard Specification for Electric-Fusion-Welded Steel Pipe for Atmospheric and Lower Temperatures
This specification covers electric-fusion-welded steel pipe(EFW pipe) with filler metal added, fabricated from pressure vessel quality plate of several analyses and strength levels and suitable for high-pressure service at atmospheric and lower temperatures.
1. Cover size:
The specification nominally covers pipe 16 in. [400mm] in outside diameter or larger and of 1⁄4 in. [6 mm] wall thickness or greater.
2. Features:
The product features of A671 EFW steel pipe include high strength, corrosion resistance, high and low temperature resistance, easy processing and installation, etc. In addition, this kind of pipeline has high reliability and safety, and its manufacturing process and quality control standards comply with international standards and industry standards, ensuring its performance and quality.
3. Material and grade:
For example: A671 CC60 CL22, A671 CC65 CL22
