Hdpe pipe pressure rating vs temperature

The relationship between the maximum operating pressure MOPthe minimum required strength of the PE pipe grade MRS and the pipe geometry SDR standard dimension ratio is given by the following industrially recognised and applied formula. It is generally recommended by our customers and design institutes that for water applications the minimum value of C is 1.

The designer may apply higher coefficients depending upon national codes of practice or judgment of local conditions and the critical nature of the application. Note, other factors such as resistance to rapid crack propagation RCP are suggested to be taken into account, particularly for gas applications, to confirm that the calculated MOP can be applied.

At an average pipe wall temperature of I hoped that due to the low thermal conductivity of PE, I could show that heat doesn't penetrate fast enough to heat up a significant portion of the wall thickness during the day. My calculations show that it does. I also hoped that the fact that only the portion of the pipe directly facing the sun would get that hot would help, but it doesn't seem to.

The location of the project is far in the north, so the sun won't be directly overhead even during the summer, but applying Stefan-Boltzman law for the expected solar radiation and an emissivity of 0. I'm wondering if anyone has any experience with something like this, or can point me to some design references that would help me analyze this problem better. Perhaps the pipe isn't suitable for the application in which case I wonder if there is a simple way of protecting the pipe from the heat.

Not sure of the supplierbut this type of pipe is used in the mining industry for tailings transfer. It is available with exterior insulation already applied. For us, its usage in freezing temperatures but ID think it would serve your purposes as well. Are you accounting for heat loss by convective cooling of the outer pipe wall to ambient air?

Pipe Class and Piping Specification - A Complete Guide

Paint it white or bury it. SlideRuleEra is correct. You need to account for the entire heat transfer picture, e. The fluid will remove a lot of the heat of solar gain. The pipe will achieve thermal equilibrium with surroundings and the fluid media. Easiest and most accurate thing to do is take actual measurements, if possible, of HDPE pipe at the location in question.

Perhaps you can run a pilot test with smaller pipe and lower flowrate at same process temperature and then scale up the findings using similitude. At the minimum this will give you accurate heat transfer coefficients.The content in this website may be used but with no warranty or liability.

Warning: All pipe plugs must be blocked or anchored adequately against a force equal to the head pressure times the cross-sectional area of the pipe. Debris or protrusions in the pipeline can damage a seal or rupture inflatable plugs. NEVER use an inflatable plug when its failure could cause injury or catastrophic damage or as the only means of protection for personnel working downstream. NEVER use a test pressure greater than the capacity of the weakest pipe or component in the system. Actual conditions vary so user must accept full risk and responsibility for the selection and use of any product.
