Manufacturing Processes of Line Pipe

Our manufacturing processes, including SMLS (Seamless), ERW (Electric Resistance Welding), SSAW (Spiral Submerged Arc Welding), and LSAW (Longitudinal Submerged Arc Welding), ensure that we cater to diverse applications with precision.

LSAW pipes, known for their longitudinal welding and high-pressure resistance, are ideal for transporting hydrocarbons over long distances efficiently.

On the other hand, SSAW pipes, with their helical welding, offer flexibility in diameter without the need for cutting.

ERW pipes bring forth efficiency with their electric resistance welding, ensuring a robust build.

While SSAW and LSAW pipes both undergo the “JCOE and UOE forming process”, their welding direction differs, with SSAW pipes being welded in a spiral position and LSAW pipes in a longitudinal direction.

This distinction, along with other factors like residual stress, welding line length, and geometry accuracy, makes LSAW pipes slightly superior to SSAW pipes in certain applications.

How to Select the Right Line Pipe

Choosing the right Line Pipe is crucial for the success and safety of your project.

When selecting a Line Pipe, consider the volume of material it will transport and the pressure it needs to withstand.

For large-scale projects, like a mainline delivering natural gas, opt for a Line Pipe with a diameter between 16 to 48 inches.For smaller pipelines branching from the mainline, a 6 to 16-inch diameter should suffice. Always prioritize safety.Ensure the Line Pipe you select meets all steel chemistry, strength, toughness, and dimensional characteristics. With UNIASEN, you’re not just purchasing a product; you’re investing in peace of mind.
