Umbilicals | Mannesmann Stainless Tubes

Umbilical Tubes

Serving the global Oil & Gas operators and fabricators our stainless steel umbilical tubing meets the toughest of specification demands.

With integrated production and extensive experience in the manufacture of Super Duplex Stainless Steels we have full control of our manufacturing routes from which we define the optimal properties of corrosion resistance and mechanical properties to meet individual Customer requirements.

Coiled Tubing:
Our umbilical tubes are typically supplied in orbitally welded coil form or upon request in straight lengths

Application: Dynamic Umbilicals

Product: Steel Tube Umbilical Lines
