Fittings

The joints, which seal and connect casing pipes between different pipe units, can be divided into three types:


      
Welding sleeve

A welded joint means that the base material in the pipe and sleeve is welded together in the contact surfaces.

Shrink muff

A shrink sleeve is a joint in which the expanded sleeve connects to the jacket pipe by shrinkage and provides a seal / force transmission. The seal consists of a layer of mastic between the socket and the pipe. The shrink sleeve can be fitted with shrink hoses as an extra seal.

Sliding sleeve

The sliding sleeve is a joint where the seal between the jacket pipe and the sleeve consists of shrink tape or shrink tubing. The method is used in simpler assembly situations.

Quality

We use proven technology when it comes to material selection, production and installation. The products undergo a thorough inspection in accordance with our quality system ISO 9001 and they are EHP certified by RISE.

Warranty

On all products we give standard warranty period of 5 years and we are backed up by a product insurance of 1mil Eur per case.

Pipes and fittings in the ground are exposed to loads of varying types and sizes, such as internal overpressure and thermal expansion. These loads must be calculated, and in some cases limited, in order for the system to have a long service life. (The limitations are described in EN 13941.) To facilitate the calculations, we have developed a unique computer-based software that our sales people are happy to tell you more about.
