The hydrostatic test of the polyethylene pipe is performed to verify the strength of the product against hydrostatic pressures. Hydrostatic test on the polyethylene pipelines at the site as well as on samples of pipes produced in a laboratory. Hydrostatic testing is often required after and repairs to ensure the correct operation of the equipment after restart.Notes on Hydrostatic Field Pressure Testing of PE Pipesthe nominal pipe diameter (DN) range to include DN16 to DN2000. The absolute expansion volumes in the larger diameter pipes has necessitated a more detailed consideration of the pressure test procedures. Where pipe volume expansion is a consideration, the hydrostatic pressure test PE Testing and Commissioning - Vinidex Pty LtdPE Testing and Commissioning. Field pressure testing PE pipelines may require special consideration due to the creep response and stress relaxation of the material. When a PE pipe is sealed at test pressure, there may be a pressure decay, even in a leak free system due to the continued expansion of the pipe through the test period.

Polyethylene pipe (PE HDPE) Properties and Types of hdpe pipe hydrostatic testing dn
The properties of HDPE PE100 pipe are determined at standard temperatures of 20°C or 23°C. These properties can be significantly affected by temperature, so at higher temperature the properties, including MRS, decrease. At higher temperatures it may be necessary to apply reduction factors to MRS, and consequently MOP.WL Plastics PE3408 HDPE Pipe Determining Pressure hdpe pipe hydrostatic testing dnmaterials must undergo long-term testing and analysis to determine the internal pressure the pipe can withstand at an operating temperature.
