Strictly adhere to and follow all applicable national and local regulations and practices. 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.

What is SDR pipe and how does it influence the pressure rating of the pipe?
High density polyethylene - HDPE - is a very popular material for water pipes. It is resistant to chemicals easy and light weighted long living low friction relatively cheap flexible tough ductile sun resistant ability to dampen water shock PE pipes can be used in range of temperatures o C to 60 o C considering the change of operating pressure.
Pressure Nominal - PN PE pipes are produced in different pressure grades PN gradeswhich indicates the pressure in bars the pipe can support with water at 20 o C.
The pressure grades available according to European standards are PN 2. Privacy We don't collect information from our users. Citation This page can be cited as Engineering ToolBox, PE Pipes - Pressure Grades.

Make Shortcut to Home Screen?HDPE is resistant to hydrous solutions of acids, alkalis and salts as well as to a large number of organic solvents. Unsuitable for concentrated oxidizing acids. Maximum temperature of HDPE pipe is the lowest among plastic pipes.
Depending on manufacturer, its upper long term temperature limit is o F 60 o C and has a short high temperature exposure of o F 80 o C. HDPE pipe, like other plastic pipe is used in low pressure applications. Like other thermoplastics, HDPE becomes more pliable when temperatures increase.
This means the maximum pressure decreases as temperature increases. HDPE pipe, like other thermoplastic piping does not fare well when exposed to ultraviolet light. This effect is commonly termed ultraviolet UV degradation. According to the ASTM specification, if plastic pipe is stored outdoors, it may require protection from weathering inaccordance with manufacturers recommendations.
HDPE joints may be fused together with a joining machine. Sticks are available in 20 foot and 40 foot lengths. Depending on the manufacturer, the pipe may be on a spool, similar to the photo above.
When shipped and installed from a spool, joining costs are much less. Design Considerations HDPE pipe, like other thermoplastic piping does not fare well when exposed to ultraviolet light.Below freezing, additional care may be required as the impact strength of PE is reduced.
The temperature to be considered for the re-rating is the pipe material service temperature, and the actual operating conditions for each specific installation must be evaluated. For long length installations a temperature gradient may exist along the length of the pipe line.
This gradient will be dependent upon site conditions, and the fluid being carried will approach the ambient temperature of the surrounds. The rate of temperature loss will be determined by inlet temperature, fluid flow rate, soil conductivity, ambient temperature and depth of burial. As these factors are specific to each installation, the temperature gradient calculations are complex.
In addition, as PE is an oxidising material, the lifetime of some grades will be limited by elevated temperature operation. Actual product life may well be in excess of these values. Where pipes are used for drinking water applications with higher disinfectant residuals, particularly at elevated temperatures, further consideration may be required.
Note that the rerating factors the temperature rating Tables below differ from the suggested temperature rerating sub-factors in the previous Table for design factors in that they are PE material specific and cover a wider range of temperatures. Where the Table for design factors for water and sewerage pipe systems is being used as a means of determining an alternative overall design factor, and the pipe is conveying water, it may be appropriate to substitute the factors in the temperature ratings Tables below for the more general temperature sub-factors in that Table.
ISO — Plastics piping and ducting systems — determination of long-term hydrostatic strength of thermoplastics materials in pipe form by extrapolation. If the proportion is less than unity, the material is satisfactory.
Pumped system normally working at a maximum head, including surge of 60m. Pump operation is for 10 hours per day, with a system life of 15 years. Total proportion is 8. Expansion and contraction of PE pipes occurs with changes in the pipe material service temperature. This is in common with all pipe materials and in order to determine the actual amount of expansion or contraction, the actual temperature change, and the degree of restraint of the installed pipeline need to be known.
For design purposes, an average value of 2. The relationship between temperature change and length change for different PE grades is as shown in the Figure below. In addition, the frictional support of the backfill against the outside of the pipe restrains the movement and any thermal effects are translated into stress in the wall of the pipe. Accordingly, in buried pipelines the main consideration of thermal movement is during installation in high ambient temperatures.
Under these conditions the PE pipe will be at its maximum surface temperature when placed into a shaded trench, and when backfilled will undergo the maximum temperature change, and hence thermal movement.
In these cases, the effects of temperature. Need some help? View our Product Support area for downloads, installations and jointing procedures. Learn more. PE Temperature Considerations.
The average material temperature may be determined: across the pipe wall, with the average temperature taken as the mean of the internal and external pipe surface temperatures where a temperature differential exists between the fluid and the external environment.

The pressure rating of the pipe is sufficient at 30 degrees, however I'm concerned about further heating of the pipe due to solar radiation.
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.inspection of HDPE PIPE
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? Paint it white or bury it. SlideRuleEra is correct.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.
