The history of KWH Pipe starts 8 decades ago with the two innovators Emil Höglund and Edvin Wiik. KWH is to this day a family business, divided into four business groups. From a modest start in the timber industry, it is today a significant player in several different industries.

One August night in 1929 Emil Höglund and Edvin Wiik were sitting at the Finnström Inn in Maksamaa discussing their future. They were both in the timber business, Emil Höglund as a clerk at Hellnäs sawmill and Edvin Wiik as an independent buyer selling timber to the sawmills. Their discussions that night led to the establishment of the Wiik & Höglund Timber Company on 28th August 1929. Edvin Wiik, born in 1897 to a farmer in Teerijärvi, and Emil Höglund, born 1901 to a tailor in Pietarsaari rural district, became partners who would work side by side for the rest of their lives.

It was, however only after the Second World War that the Group moved into plastics with the manufacture of plastic floor tiles. Further diversification into pipes ensued, and in 1955 the first polyethylene pipes were delivered to customers.

In 1976 KWH Pipe became the first company in the world to successfully manufacture 1600mm diameter extruded, solid wall, polyethylene pipes. Even today, KWH Pipe remains one of the few manufacturers who can produce this diameter of pipe.

KWH Pipe supplies plastic pipes into an extensive international market from water supply and drainage to piping for district heating and gas distribution. In addition, the company manufactures PVC pipes for the Scandinavian market and a range of machines for butt fusion welding of polyethylene pipes.

Latterly, KWH Pipe developed Weholite®, an innovative lightweight pipe for non pressure applications, which can be manufactured up to 3.5 metres in diameter. To meet the global demand, increasing numbers of Weholite manufacturing plants has been established world-wide.
