Longitudinally Welded Steel Pipes
LSAW (Longitudinally Submerged Arc Welded) pipes are welded along the length of the pipe and can be manufactured in two distinct methods, each offering its own set of advantages.
In the first production method, a coil is used. The coil is unrolled and folded widthwise to create a circular shape. Subsequently, the seam is welded, forming a “longitudinal seam” along the entire length of the pipe. This continuous process continues until the coil is fully unwound, making it suitable for standard diameters and thicknesses.
The second production method involves using a steel plate, the plate is rolled into a pipe shape tailored to the customer’s project specifications. These pipes are welded along the length of the pipe. Due to the limited length of separately produced pipes, they are typically joined together using a round seam. This method is suitable for projects that require particular sizes, such as thick-walled pipes.
Applications include piles, bored piles, mooring posts/fenders, jetties, and piping.
Smart Steel Solutions
In a rapidly changing world with a constant focus of the reduction of CO2 emissions we want to swim along with the current. We do so by providing our customers with smart steel solutions; tailor-made and in-house produced steel products. With the wishes and requirements of the project in mind, we are able to provide our customer with the best suitable solution and tailor-made product.
