Application
Gas pipelines
Gas pipeline sealing and corrosion protection, when the consequences of failure are different
Stakes of failure
In a gas pipeline, the consequences of failure are on another level entirely from district heating. Kampek supplies Covalence heat‑shrink sleeves and Stopaq systems for joint sealing on gas distribution and transmission networks, from urban distribution to long‑distance transport pipelines.
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.
