Description

ASTM A671 is a specification for electric-fusion-welded steel pipe suitable for atmospheric and lower temperatures. It covers pipes made from carbon and alloy steel, with various grades and classes available. These pipes are commonly used in industrial applications, such as power plants, refineries, and process piping systems. The specification sets requirements for chemical composition, mechanical properties, dimensions, and testing methods to ensure the quality and performance of the steel pipes.
