HDPE pipe can also be classified by the material used PE 100, PE 80, PE63, PE 40 or PE 32. Pressure Nominal PN PE pipes are produced in different pressure grades (PN grades), which indies the pressure in bars the pipe can support with water at 20 o .
Metric Poly Pipe is available in PN10 (maximum pressure rating of 1000kpa), PN12.5 (1250kpa) and PN16 (1600kpa). The ‘mm’ measurement represents the Outside Diameter (OD) of the pipe. Prices are ex. WA. For orders with over $1000 worth of Poly pipe
The ASME Code for Pressure Pipe, in B31.4, requires hydro test at thetimes the MAOP (maximum allowable operating pressure) for HDPE pipe. Typically, for ductile, viscoelastic HDPE pipe, the hoopstress during hydrotest should exceed 30% of the

Our HDPE pipe for water and sewer is manufactured for excellent performance and a long life expectancy. Its butt fused joints eliminate potential leak points, common at 10 to 20 feet with ductile iron pipe, for a zero leak rate. Highly resistant to corrosion and
Our pressure pipe is used in many types of appliions such as potable water, sewer, drain, mining, irrigation, slip lining, and reclaimed water. Materials: JMM HDPE pressure pipe is manufactured with premium, highly engineered PE4710 resin that provides Puhui Pipe manufacturer in China
* "Pression Nominal" is the French equivalent of Pressure Nominal "Pression Nominal" is the rating designator followed by a designation nuer indiing the approximate pressure rating in bars. 1 bar = 1x10 5 Pa (N/m 2) = 0.1 N/mm 2 = 10,197 kp/m 2 =
PP compressure fittings, Pressure rating: SDR 17 (PN10), SDR 11(PN16), with size from DN20mm 400mm. 6. HDPE Special customized fittings, Pressure rating: SDR 41 SDR 6, with size from DN110mm 1600mm.
My understanding is that it represents the amount of the pressure that pipe is capable of handling. So in this example being PN10 means it can handle a maximum of 1000 KPA. We typically reference this when we look at water and gas pipes made out oPuhui Pipe manufacturer in China
Test pressure is 1.5 times the pressure rating of the lowest rated component in the system. Flow and pressure are logged throughout the test. Pass/fail criterion is based on the flow of water required to maintain the test pressure in the pipe.

pipe can reach temperatures of 40 C. The maximum pressure in the system is 900kPa. The chart below indies that PN10 has a maximum pressure rating of 750kPa at 40 C and therefore is clearly not sufficient. After factoring in a 10% safety margin
31/8/2016 My special concern is regarding vacuum pressure generated just after the pump closure of a pressured flow system. Therefore I want to know whether the HDPE pipes can withstand this negative vacuum pressure and to what extent of the negative pressure pipe will not brake.
