In the 1970's KWH Pipe introduced a foaminsulated system and were among the first with a CFC-free foam insulation. When manufacturing, KWH Pipe uses polyurethane foam for insulation, polyethylene and galvanized or PVC coated spiral wound steel for casing pipe, and various steel and plastic pipe alternatives for carrier pipes.

Wehotherm represents 30 years of craftmanship and experience. It is produced to meet the requirements of Euronorms (EN253, 448, 488 and 489 / rev.1994) and is insulated with the environmentally friendly Wehofoam polyurethane insulation with excellent insulating and mechanical capabilities.

Wehotek industrial piping meets the requirements of specific industrial applications and conditions. The carrier pipes can be manufactured as single-pipe or multi-pipe. They are available in a number of metal and plastic alternatives. Insulation can be done with polyurethane foam or, if needed, with a combination of mineral wool and polyurethane. We can also offer pre-stressed pipes and pipes for applications where long intervals between supports are required.

Wehoarctic is a pipework system, which effectively protects water and sewage pipe systems against frost. Casing and carrier pipes are available in a number of steel and plastic alternatives.
