Large-diameter pipe plants

Tube and pipe making

Large-diameter pipe plants for pipes from 16” – 64”

Whenever large amounts of liquids or gases have to be transported over long distances, pipelines are the answer. They supply industry with raw materials and drinking water to cities, and transport energy resources around the world. However, large-diameter pipes also play an important role in other fields. Included here are construction or piling pipes for offshore projects.

Individual components of LSAW pipe plants

When pipes have to withstand high internal or external pressures, high wall thickness is used and LSAW (Longitudinal Submerged Arc Welding) pipes are usually the most economical solution. In LSAW pipe mills, processing is done by cold forming of heavy carbon steel plates. Among the three main forming processes SMS group focuses on the JCO process. We supply the equipment for everything from the first to the final process step. That includes not only the core machines, but also all the upstream and downstream process steps required for the production of large-diameter pipes.

Solutions for automated pipe forming
Shape automation system

Our Shape automation system gives you precise information on the geometry of your pipes during all forming steps. It measures ovality, straightness, weld seam, and pipe ends with high accuracy for automatic quality assurance.

Digital Welding with PERFECT arc by SMS group

Higher productivity and over 30 percent less energy consumption
Perfect arc^® digital welding

PERFECT arc^® is a digital welding process newly developed by SMS group. It's equally suitable for spiral pipes as well as longitudinally seam welded pipes. The solution is ideal for both arc and submerged-arc welding.
