Overview of ASTM A252 Spiral Welded Pipe
ASTM A252 Spiral Welded Pipe is a standard specification for welded and seamless steel pipes used in structural applications such as piling, foundation supports, and infrastructure projects. This standard, issued by the American Society for Testing and Materials (ASTM), ensures that the pipes meet high mechanical strength, weldability, and durability criteria.
Spiral welded pipes under ASTM A252 are mainly used for bearing and casing applications, making them ideal for bridge foundations, marine piling, and underground construction projects. Their helical seam يوفر greater pressure resistance and load-bearing capacity, making them a cost-effective alternative to seamless pipes.
In this guide, we will cover everything about ASTM A252 Spiral Welded Pipes, including manufacturers, specifications, price trends, coatings, applications, and welding processes.
