External Load Design Calculator for PVC Pipe


Ningbo Fangli Technology Co., Ltd. is a mechanical equipment manufacturer with nearly 30 years’ experiences of plastic pipe extrusion equipment, new environmental protection and new materials equipment. Since its establishment Fangli has been developed based on user’s demands. Through continuous improvement, independent R&D on the core technology and digestion & absorption of advanced technology and other means, we have developed PVC pipe extrusion line, PP-R pipe extrusion line, PE water supply / gas pipe extrusion line, which was recommended by the Chinese Ministry of Construction to replace imported products. We have gained the title of “First-class Brand in Zhejiang Province”.

The PVC Pipe Association has released an online version of its external load design program for calculating earth and live loads for PVC pipe. It follows the method outlined in the 5th edition of the Handbook of PVC Pipe Design and Construction.

Users can input project conditions such as pipe size, pipe stiffness, depth of burial and live load type as well as soils-related options such as unit weight of soil and E' for embedment. Based on input variables, the calculator will provide theoretical loads (in psi) and pipe deflection expressed as a percentage of diameter.

Designers of buried PVC pipe will find that this calculator streamlines the design process and provides the ability to quickly determine a pipe's deflection and/or to perform a sensitivity analysis for various installation conditions.
