TCP Flowlines

Solution for in-field flowlines

TCP Flowline eliminates corrosion and is the lowest total installed cost solution for greenfield, brownfield and hydrogen applications.

In Strohm, we design and manufacture TCP Flowline products for hydrocarbon production, water injection, gas lift, chemicals injection and renewable applications. Its non-corrosiveness, smooth bore, low weight, spoolability and ability to terminate in the field make it the best solution for in-field flowlines, tiebacks, single well step-outs, (quasi) static risers and inter-array lines (renewables).

The solid pipe structure is impervious to corrosion, resulting in outstanding performance in corrosive environments and low, or no operating cost at all. It has an inner, fully bonded, smooth bore polymer liner that ensures the best attainable flow properties while still being piggable. The thermal performance of TCP is considerably better than that of steel (reinforced) pipe. Our end fittings are simple and robust, relying on a well-proven mechanical clamping method. Assembly of the pipe with our end fittings is straightforward, can be done both onshore and offshore and at any location on the pipe.

Our TCP Flowline is supplied in long spoolable lengths for cost-effective horizontal lay and lowest as-installed cost. We can install TCP Flowline using small, multi-purpose vessels, greatly reducing installation cost, to a radical 30% saving on as-installed cost or more, as shown in the TCP Flowline business case. In addition, the lack of corrosion reduces corrosion-related cost such as pumping of corrosion inhibitors, relating pigging, etc.

Our designs and selection of materials are adapted to the specific requirements of each project, ensuring a fit-for-purpose and highly cost-effective solution for each project. We manufacture TCP Flowline up to 7.5 inch ID, 121 degrees Celsius (250 F) and 10 ksi working pressure. 

Storage, Transportation and Installation Reels
Flowlines are supplied on storage, transportation and/or installation reels, allowing deployment with a reel drive system. The reels can be offered on a purchase or rental basis.

Ancillaries & deployment
We supply our end-fittings with the following ancillaries, depending on the product and application:

  • Bend restrictors
  • Bend stiffeners
  • Installation ancillaries
  • Anodes
