Abstract
The irrigation systems, water supply system, sewage water system ….etc. Dealing with many types of pipes and fittings depending on the applications. The current study was concert on test the polyethylene (PE) and polyvinyl chloride (PVC) pipes experimentally and theoretically under external loads and internal pressure to simulate the application conditions of pipes which are buried under ground used to transit the fluid under pressure such as drink water, sewage water or any other purpose and find out the deformation, stress and strain due to this loads. The tested was carried out for two size (actual and standard) of the two pipes (PE and PVC). The external load represented by a force in range (10-50KN), and the internal loads represented in pressure in range (5-20 bar). In the experiment a hydraulic press was used to supply the external load and hydraulic pump to supply the internal pressure with two adapter on the two end of tested pipe. The results showed that the deformation, stress and strain increase with increase in internal and external loads and the peak values of that were in the maximum internal and external loads (20 bar internal pressure and 50KN external force), also the experimental tests match the numerical calculation for both actual and standard size.
