Pipeline coatings

For guaranteed corrosion free gas, oil, water transmission and distribution pipelines, underground flanges and valves, and pipe saddles STOPAQ is the answer.

STOPAQ can be applied for pipeline rehabilitation work, in the shop or even at the jobsite in our special mobile coating plant. The mobilization and demobilization costs are extremely low compared to conventional systems. SA2,5 blasting with a roughness profile of min. 75 microns is not required. The systems are simple and easy to apply. The system does not require special primers or adhesive for mechanical fixating the coating. The system does not require curing time, so backfill can be done immediately.
