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.

Longitudinally welded large-diameter pipes produced on our plants are hightech products. Tough enough for all conditions, they withstand wide temperature fluctuations, high pressures, as well as acidic and corrosive gases.

With plants from SMS group you achieve even better quality, more flexible and more cost-effective processes, more precise dimensions and closer pipe tolerances.


The right process to meet every requirement

Individual components of LSAW pipe plants

Today, there are two important processes used in the production of longitudinally welded large-diameter pipes. They are UOE and JCOE®, a process developed by SMS group. 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 projects in a large-diameter pipe plant.

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.

Perfect arc digital welding image

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 UO and JCO® pipes. The solution is ideal for both arc and submerged-arc welding.
