Stopaq Mechanical Protection Materials

The Stopaq Corrosion Prevention Systems are always Separated from the Function of Mechanical Protection.

STOPAQ systems always consist of minimally two layers:

  1. Corrosion Prevention
  2. Mechanical Protection

The specially formulated and patented corrosion prevention layer adheres tenaciously to even the most difficult substrates and provides good elevated temperature creep resistance and resistance to soil stresses.

Adhesion & Creep Resistance

Improved soil resistance is achieved by applying the second mechanical protection layer. STOPAQ is ideally suited for all diverse ranges of pipeline applications such as: transition areas from above to below ground pipelines; special parts such as bends, tees, flanges etc, plus rehabilitation of existing pipelines.

The mechanical protection layer provides supplementary soil stress resistance. Improved soil stress resistance is achieved with the application of an Outerwrap. We would always advise our clients of which mechanical protection material would be the most effective for each project whether it is an above ground or below ground application, onshore or offshore etc.
We also always consider the following :-

  • pipeline operating temperatures
  • expected axial pipeline movement
  • expected circumferential forces
  • expected soil stress forces
