PE Temperature Considerations - Vinidex Pty Ltd

Effect of Temperature on Pressure RatingPipe Design For Variable Operational ConditionsExpansion and ContractionThe physical properties of Vinidex PE pipes are related to a standard reference temperature of 20°C. Where physical property values are quoted to ISO and DIN Standard test methods, these are for the 20°C condition, unless otherwise quoted. PE pipes may be used at operating temperatures between -40°C and +80°C. For temperatures less than 20°C it is convention to use the 20°C hydrostatic design stress. Below freezing, additional care may be required as the impact strength of PE is reduced.

What Temperature Range for PVC Pipe? Hunker

Temperature changes can cause slight variations of the dimensions of PVC piping, most notably in the length of the pipe. Generally speaking, you can expect a change of approximately 3/8-inch in length per every 100 feet of piping for every 10 degree F temperature change; this rule is typical of all PVC piping regardless of diameter.What Temperature Range for PVC Pipe? HunkerThe precise upper temperature limit can vary slightly depending on the exact specifications of the PVC pipe. However, generally speaking, the upper limit of PVC pipes is 140 degrees F; beyond that temperature, the PVC piping is at risk of losing its structural integrity. Temperature Effect on What is PN - What is PN in HDPE pipe?Polyethylene pipes ( HDPE Pipes) are produced at different work pressures (PN), and this work pressure (PN) is tolerable for pipes at temperatures of 20 °C. This temperature is best for polyethylene pipes.
