Perma Engineered Sales Limited: Piping Systems Map

Manufactured by KWH Pipe (Canada) Ltd., this high density polyethylene pipe (HDPE) is ideal for a variety of mining, industrial and municipal applications such as transmission mains, sewage forcemains, intakes, outfalls, pipe relining, and irrigation systems to name a few.

Rugged, flexible, lightweight, corrosive resistant, abrasion resistant and leak proof, SCLAIRPIPE is available in sizes from 3/4" to 63", and pressure ratings from 36 to 300 psi.

SCLAIRPIPE's mirror smooth interior surface offers a higher co-efficient of friction to flow than other piping materials, which translates into lower pumping costs.

SCLAIRPIPE's butt fusion joining method offers a unique continuous leak-proof seal. This positive thermal fusion joint offers an economical and reliable method for joining pipe. When integrated into a piping system, lower inground maintenance costs are realized. The butt fusion joint is as strong as the pipe itself, making SCLAIRPIPE ideal for surface and marine specifications. In areas where the ground conditions are unstable, the joints will not separate as in gasketed systems.

SCLAIRPIPE has a tremendous record in the mining sector where it is constantly used for abrasive tailing lines, outlasting other piping materials 5 to 1. SCLAIRPIPE meets or exceeds all North American standards for high density polyethylene pipe.

The SCLAIRPIPE piping system includes all accessory items such as mitred fittings, stub ends, etc.
