District heating
EN‑489-compliant joint sealing for Finnish district heating networks
Sealing and corrosion protection of district heating joints is critical to network lifetime. A leaking joint means a dug‑up street, interrupted heat supply, and tens of thousands of euros of cost. Kampek supplies two proven systems for the same problem: Covalence heat‑shrink sleeves and BG Industry sleeve fittings.

Choose this when the joint is on pre‑insulated pipe and the sizes vary: the sleeve is wrapped on site and covers casings from 90 to 1200 mm, including repairs and dimensions outside a standard series.

Choose this when the pipe size falls in the DN 90–450 standard series and many similar joints are made: the prefabricated sleeve is fast and repeatable, available as heat‑shrink or electro‑weldable, and the joint is leak‑testable.
