10/8/2016· PVC pipe tensile strength can be measured by hanging weight from the pipe until it bends or cracks. As you can see from the chart to the right, tensile strength of PVC pipe increases as the size of the pipe increases. 8" PVC pipe of either schedule is extremely strong for how inexpensive it is.
2 · A corrugated drainage pipe is also known as a French drain. The pipe contains small holes on one side in order to allow it to absorb water from the soil. It is important to properly bury a corrugated drain pipe so that water does not make its way back to the surface and cause problems such as erosion and standing water.

Questions about the maximum burial depth for PVC pipe are often asked by people in the water main detection and pipe detection fields, especially in regards to PVC sewer pipe. Sewer detection involves using GPR or other instrument to map the loion of underground piping. The best way to loe underground PVC pipe is with a device called the AML PVC Pipe Detector from SSI Loors. The Puhui Pipe manufacturer in China
While the minimum pipe stiffness of 46 lbs/in./in. for standard strength PVC gravity sewer pipes has proven to be good for burial depths in excess of 40 ft, PVC pipes are available with pipe stiffness values up to 1,019 lbs/in./in.
Underground water service piping must be buried at least 12 inches below grade. e. PVC and CPVC-type drain, waste or vent pipe and fittings installed underground or under or through slabs, driveways, patios, foundations, etc., must be Schedule 40
