Stopaq corrosion protection for refineries, process piping and offshore structures
Stakes of failure
Process piping, refineries, offshore lines and splash zones demand corrosion protection that needs minimal surface prep and no blasting. Stopaq's self‑healing polyisobutene installs cold, flows into surface irregularities, and repairs itself from small defects.

Frequently asked questions
Questions and answers
What protects buried gas and oil pipes?
Buried steel lines and their joints are protected with Stopaq's cold-applied polyisobutene wrap, with a mechanical Stopaq Outerwrap on top. At road, rail and waterway crossings the casing annulus is filled with Stopaq Casing Filler.
Can Stopaq be applied without taking the pipe out of service?
Stopaq is applied cold and without blasting, so the pipe can often stay in service during the work. We assess the right procedure for the site, so do ask.
Does the protection interfere with cathodic protection?
No. Stopaq is compatible with cathodic protection, which matters on long buried transmission lines. The protection and the cathodic protection work together.
What temperature and load does the protection withstand?
Stopaq Wrappingband withstands −45 °C to +70 °C in service and +90 °C short-term. The mechanical Outerwrap protects the wrap from impact and indentation during and after backfilling.
Does the system also suit crossings and casings?
Yes. Stopaq Casing Filler fills the annulus between the casing and the carrier pipe at crossings, and the Stopaq wrap also protects fittings and penetrations. Tell us the type of site and we suggest the right combination.
