Weholite Pipes
Weholite is spirally wound pipe or flat panel, manufactured from corrosion-resistant HDPE, to provide a light weight, engineered solution with superior loading capacity that is chemically inert and provides a projected 120-year design life.
Weholite pipeline products are used in a wide variety of applications including drainage and sewer networks, stormwater attenuation tanks and soakaways, flood relief culverts and CSO flood alleviation schemes. Designed for both online and offline situations, these products have been utilised by most of the major developers and adopted by all of the UK Water Companies.
Weholite pipeline products are also used in the Water Industry Capital Investment Programme (AMP) for water management infrastructure, and on major surface water drainage projects including highways development and repair, Network Rail improvements, Schools Building Programme, Energy from Waste projects and CSO flood alleviation for properties on the DG5 register.
Weholite Pipes Factsheet
* The uniqueness of the Weholite production process means that pipes can be run in any length from 300mm to 30m in one piece. All projects are designed to optimise pipe length to ensure efficient installation and value engineering.
** Pipe stiffnesses above 8 and special designations in between the sizes above are available by special request.
All dimensions are subject to change.
