Pipeline professionals and students are now offered a helping hand by KWH Pipe. KWH Pipe's online calculator evaluates your selection or recommends the best pipe size and grade to suit the hydraulic capacity, internal pressures, pressure surges, thermal factors and burial conditions of your application.

Calculation modules are available for both Weholite structured-wall pipe and WehoPipe/Sclairpipe PE-HD pressure pipes. The program is a supplement to KWH Pipe's design brochures, PE Pressure Pipe Systems, Sclairpipe Systems Design and The Basics of Weholite. It also is based in part on the Plastic Pipe Institute - Handbook of Polyethylene Pipe, and the ISO, EN, ASTM and CSA specifications that are relevant.

Use of the program is not intended to replace the evaluation and judgement of a professional engineer competent in this field. It should be considered as a tool to evaluate design conditions. The user is expected to have an understanding of the equations and principles involved, their applicability and limitations.
