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.

SSAB Large diameter piles in deep and steep Norwegian fjords
Green shipping has long been a goal for Norwegian transportation. This has led to heavy investments in electric and hybrid transportation ferries. These ferries are used to allow road traffic to pass over the huge number of fjords along the Norwegian coast line. In 2021, 70 ferries out of a total 200, more than 1/3, had been replaced by electric ones. This transition has been backed by national funding and has also triggered demand for infrastructure development.
