Stopaq corrosion protection for refineries, process piping and tanks

Request quote →040-502 9474
Stakes of failure

Process piping, refineries, tanks and steel structures 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.

Product families that solve this
Applications

Where Stopaq is used

  • Piping and flanges
  • Steel structures
  • Buried lines
  • Crossings
  • Under insulation
  • Cladding and sealing
  • Cold lines
  • Splash zone
Steel structures and pipe bridges
Steel structures and pipe bridgesA pipe bridge's steelwork, joints and nodes wrapped in place. No dismantling, no blasting.
Valves and supports
Valves and supportsIrregular shapes: a valve, a flange and a pipe support on one line. The compound is shaped by hand.
Corrosion under insulation
Corrosion under insulationProcess pipe bends wrapped before the insulation goes back. Works on an already rusted surface.
Storage tanks
Storage tanksTank roof seams and the chime at the base, the usual leak points. Cold‑applied, no hot work on the tank.
Process piping
Process pipingHot and cold lines on one rack. Wrappingband for service from −45 to +70 °C.
Buried gas lines
Buried gas linesA valve station before backfill. Compatible with cathodic protection.
Road and rail crossings
Road and rail crossingsThe annulus between casing and carrier pipe filled with Casing Filler from a tanker.
Wind turbines
Wind turbinesThe joint between foundation and tower. No primer and no blasting kit to carry into the forest.
Wall penetrations
Wall penetrationsA pipe passing through a wall, where water stands and the steel is bare.
Frequently asked questions

Questions and answers

What protects buried gas pipes and steel lines?
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.
