A new technical manual from Hepworth Plumbing Products provides the company’s most comprehensive ever guide to its range of Hep3O® plastics alloy water pressure systems. Designed for potable water and sewage applications, Hep3O® offers pipes and fittings in diameters from 63mm to 630mm in 8, 10, 12.5 and 16 bar pressure ratings.

The guide covers the material properties of the unique plastics alloy used in manufacture, as well as system components and performance, together with dimension and weight data for each product. A separate section explains the characteristics of the Power-Lock seal, which provides a highly effective push-fit joint offering exceptional performance under positive or negative pressure.

Technical information is provided on fracture toughness performance, chemical and corrosion resistance.

A design section has been compiled to help specifiers take account of factors such as hydraulic design, surge and fatigue, external compressive loads and deflection. There is also a useful guide to the codes of practice and regulatory documents relating to pressure system specification. A detailed installation guide provides full site work instructions.
