The Process and Specifications of EN10219 Welded Steel Pipe Piles

EN10219 welded steel pipe piles are manufactured using various processes and adhere to specific standards and specifications. This article will delve into the different processes involved in producing these pipe piles and provide an overview of the specifications and certifications associated with them.

Manufacturing Processes

LSAW (Longitudinal Submerged Arc Welding)

LSAW is one of the primary processes used in the production of EN10219 welded steel pipe piles. It involves the use of a longitudinal seam welding technique. The three common types of LSAW processes used for manufacturing these pipe piles are:

1. UO (UOE) – UO stands for “U” bending and “O” forming. In this process, the steel strip is first bent into a U shape and then formed into an O shape, creating a cylindrical pipe.
2. RB (RBE) – RB stands for “R” bending and “B” expanding. This process involves bending the steel strip into an R shape and then expanding it to form a cylindrical pipe.
3. JCO (JCOE) – JCO stands for “J” bending, “C” forming, and “O” expanding. This process involves multiple steps, including bending the steel strip into a J shape, forming it into a C shape, and finally expanding it to create a cylindrical pipe.

DSAW (Double Submerged Arc Welding)DSAW is another process used in the production of EN10219 welded steel pipe piles. It involves the use of two submerged arc welding heads to create a double-sided weld. This process ensures a high-quality and strong weld, making it suitable for demanding applications.
