Install it once. It protects for decades.
The weakest point of a pipe is the joint, and that is what Kampek protects. We supply Covalence, Stopaq and BG Industry corrosion protection and joint sealing systems to Finland's district heating, gas and oil networks.
The weakest point of a pipe is the joint. That is where corrosion starts.
Damage almost always starts at the joint, or wherever the steel is left bare, whether the line carries district heating, gas or an industrial process. Kampek supplies the protection for exactly those points. The product families split into two jobs.
Sealing the joint casing of pre‑insulated district heating and cooling pipes. The joint stays dry, and the insulation stays dry for the service life of the pipe.
Covalence · BG IndustryProtecting buried and industrial lines against external corrosion. Self-healing protection for bare steel, applied cold without blasting.
Stopaq
Covalence, Stopaq and BG Industry, all three shipped from our Tuusula warehouse.
Covalence and BG Industry go on district heating and cooling joints; Stopaq handles corrosion protection.
One install lasts the service life of the pipe in the ground.
The figures come straight from the manufacturer datasheets.
| Traditional method | Stopaq + Covalence |
|---|---|
| Coating recoated about every ten years | Lasts the service life of the pipe in the ground |
| Blasting and priming before application | Wire brushing to St 2 is enough, no primer |
| Coating cracks when the ground moves | The visco-elastic compound self-heals small defects |
| Can interfere with cathodic protection | Compatible with cathodic protection |
| Curing time before backfilling | Applied cold, can be covered immediately |
| Applied with a torch or by blasting | Applied cold, no torch |

What longer protection means for the network owner.
The same joint lasts longer in the ground and the work goes fast on site. The products ship from one warehouse in Tuusula.
Longer service life lowers lifecycle cost
When a joint lasts in the ground for the service life of the pipe, that spot does not need to be dug up and recoated as often as a traditional coating.
Fewer maintenance shutdowns
Stopaq's self‑healing protection fills small defects by itself, so a single point of damage does not start corrosion under the coating or trigger an unplanned repair.
Faster installation on site
Stopaq is applied cold, with no blasting and no primer. Wire brushing to cleanliness grade St 2 is enough, and the work is feasible even in tight excavations.
The pipe can stay in service during the work
Stopaq's cold application without a torch means that on many sites the pipe can stay in service for the whole job.
Compatible with cathodic protection
Stopaq does not interfere with cathodic protection, so the coating and the cathodic protection work together on long buried transmission lines.
One supplier for the whole joint
You get Covalence, Stopaq and BG Industry from the same Tuusula warehouse. We match the right product combination to the site and deliver across Finland.
Built for the organisations that own, build and maintain the networks.
The products are made for the people accountable for a pipe network's service life. Energy companies, contractors and industrial asset owners get the same protection from the same warehouse in Tuusula, across Finland.
A leaking joint means the street is dug up and heat supply is interrupted. An EN‑489-tested joint lasts the service life of the pipe in the ground and lowers the network's lifecycle cost.
The products can be specified straight into the contract and installed fast. Covalence and BG Industry are type-tested to EN 489, and Stopaq is applied cold without blasting.
Stopaq is applied cold by hand, often on a pipe in service. Even a small quantity ships quickly from stock in Tuusula.
One warehouse serves both the district heating and water networks, and Stopaq Wrappingband holds NSF/ANSI 61 approval for drinking-water contact.
For refineries, process piping and gas and oil lines. On a critical line a failure costs many times the protection. Stopaq's self‑healing protection works together with cathodic protection.
