Joining methods

Pipe joints connect pipes and fittings into an integrated pipeline.

Joints can be divided into two main types: tension resistant and non-tension resistant. Joints may also be divided by application.

Pipe fittings

Internally and externally coated pipe fittings can be easily joined to each other.

Besides standard fittings, SSAB also delivers fittings for water main pipe sizes tailored to customer specifications, considerably improving the modifiability of the system.

Coatings

External and internal coatings ensure the long life of steel water main pipes.

SSAB delivers water main pipe materials with external polyethylene coating and an internal concrete or epoxy layer suitable for use with drinking water. There are also suitable inside coatings for sewage and rainwater.
