Learn about A252 Grade 2 Steel Pipe:

A252 GRADE 2 Steel Pipe is a carbon steel pipe specifically designed for use in pressure piping and structural applications. It is manufactured in accordance with ASTM (American Society for Testing and Materials) standards, ensuring high quality standards and dimensional accuracy. The GRADE 2 designation indicates that the steel pipe is manufactured using submerged arc welding or seamless welding methods.

The importance of double submerged arc welding:

Double submerged arc welding, also known as DSAW, is a highly specialized welding process used to join sections of A252 GRADE 2 steel pipe. DSAW offers several advantages over other welding methods, including excellent weld integrity, high welding speeds, minimal distortion, and excellent control of heat input. It ensures a strong bond between pipes, making them less prone to leaks, corrosion and structural damage.
