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.
