TReK STS BV is the Rotterdam based distributor for TechnipFMC – Coflexip division, supplying flexible steel pipes for more than 30 years, finding its application in the petrochemical tank storage and refineries.


Drain Systems

The unique construction of Coflexip® flexible steel pipes have a repetitive lay pattern, ideal for a simple, reliable and thus economical drain system for floating roof tanks.

Foam Systems

Our system fills the rim of the floating roof with foam within 3 minutes, guaranteed. Limited maintenance needed, easy installation, fast working. Cost saving all the way.

Decoking High Pressure Lines

Extreme reliability and a long lifetime, the key to avoid expensive maintenance and downtime of a decoking system

Skimmer Systems

The repetitive lay pattern needs only a limited space in the tank, ideal for smaller diameter tanks needing a suction or skimmer system.

The repetitive lay pattern is created by the unique construction of the of Coflexip® flexible steel pipe. A stainless steel inner carcass, and a non-bonded high chemical resistant thermoplastic outer jacket make flexible steel pipe lay itself in the same position over and over again. Small space needed in the tank, only one component in the system, are the keys to reliability.

TReK STS and Coflexip® are engaged all the way, we measure, we supply installation drawings, we support your contractor and we make a final inspection once the system is built in. All systems are custom engineered for your specific storage tank. Our way of supplying a reliable product for a trouble free operation.
