Pressure Ratings are calculated using 0.63 design factor for HDS at 73°F as listed in PPI TR-4 for PE 4710 materials. Temperature, chemical and environmental use considerations may require use of additional design factors. Pipe weights are calculated in accordance with PPI-7 TR-7.
31 maj 2023 · Table below provides dimensions of HDPE pipes for PE100 material of rating PN25, SDR 7.4 or S3.2. The following section provides a brief background of the various definitions used and the applicable calculations while referring to PE pipes.
Pressure ratings shown are applicable to aqueous solutions including up to 2% hydrocarbons at 80oF. Gajeske HDPE may confirm to these standards: ASTM F714, F2619, D2513, D3350, API 15LE, AWWA C906, AWWA C901, ASTM D3035.
Internal Pressure Rating: Stress due to working pressure cannot exceed the HDB (1,600psi) ÷ 2.0 safety factor (Hydrostatic Design Stress = 800psi) for PE 100
2 dni temu · IPS and Large Diameter Metric HDPE Pipe Size Chart. Chart is for reference only. Actual dimensions may vary based on certain applications. Pressures are based on using water at 23°C (73°F). Average inside diameter calculated using actual OD and minimum wall plus 6 percent for use in estimating fluid flows. Actual ID will vary.
DR 7 (335 psi) take in consideration pressure class of fitting. Typically, the disinfectant is 3ppm chlorine - and chlorimines (and in some few cases, chlorine dioxide).
5 maj 2021 · fabrication of VERSAPIPE® HD100 PW pipe for potable water and wastewater transport applications at operating pressure up to 2,3 MPa (333 psi). The maximum recommended operating temperature for pressure service is 60 °C (140 °F).
