KWH Pipe products are manufactured from special, high strength resins with complete quality control maintained from raw material to finished pipe product. KWH Pipe was the first North American manufacturer of polyethylene pipe and fittings to have its Quality Management System registered to the ISO 9001 level.

The company’s strict manufacturing specifications are verified daily, using precise dimensional controls and accelerated long term hydrostatic testing. One result of this continuous quality control is the ability to accurately predict long-term pipe performance.
