The handbooks of PE pipe were released by Plastic Pipe Institute as a guide for those seeking to use these pipes in the industry. In these handbooks, the advanPE100 ISO9001es of PE pipes are highlighted and also tips for buyers of all types of PE pipes and all of their appliions are mentioned to make the best choice at the most affordable price.
The tests for the PE100+ Association are performed on 110 mm SDR 11 pipes as "water-in-water" test. In terms of lengths of the pipe, the standard requires at least three times the outside diameter. For pipes bigger that 315 mm outer diameter, a minimum length 1.000 mm shall be used. Stress crack resistance Pipe PE100

Plastic pipes are an essential part of the water and gas distribution systems. We offer plastic pipe testing services to ensure that your products are thoroughly tested for integrity of the weld and the capability to handle the required pipe pressure.
Hdpe pipe measurements such as Hdpe pipe wall thickness, Hdpe pipe diameters, hdpe pipe weight are calculated based on the mentioned tolerance values. Hdpe Pipe, Polyethylene PE Pipe are ranked according to strength classified according to the density of previous technological developments.
HDPE pipe has a C-Factor of 150 for the design life of the pipe, unlike metallic pipes which will suffer inside diameter constriction overtime. The inside diameter of HDPE pipe will not change over time providing consistent flows with no increase to pumping energy.
Maintaining dimensions within specifiions is problematic for the extrusion of large diameter thick-wall polyethylene PE pipe > 75 mm wall due to sag caused by insufficient resin melt strength. However, sag can be controlled through careful resin selection and optimization of the pipe cooling process.
Our testing services include Pipe pressure tests hydrostatic pressure testing Impact tests at various temperatures Pipe dimension determination tests Temperature exposure and derating testing Material characterization and durability testing.
Testing Procedures For HDPE Pipe Pressure Testing Outside The Trench: • If specified by the engineer, pressure testing may be conducted prior to pipe installation. • After the pipe has been joined, fill it with water, carefully bleed off any trapped air. Subject the
1- Keep in mind that the total hydrostatic test time on a plastic pipe system at a pressure above design pressure should never exceed 8 hours. If there was a piece of piping during which the design would recommend a longer time for it and the time was longer than 8 hours, at the end of the first 8 hours, the test should be stopped and the pressure inside the system should reach zero.
Even in heavy-loaded areas, where only the strongest — Galvanized iron, Ductile iron, Cement Pipe survive, Plastic in the form of HDPE has scored beyond doubt as an ideal substitute. HDPE is today, the internationally preferred piping material across an unbelievable range of appliions where strength & long life are key requirements.
Leak tests of non-pressure systems typically involve testing sections of the system or individual joints using end plugs or bulkheads to determine resistance to leakage. Hydrostatic pressure leak tests of PE pressure piping systems should be conducted in accordance with ASTM International F 2164, Standard Practice for Field Leak Testing of Polyethylene PE Pressure Piping Systems Using Hydrostatic Pressure.
HDPE Pipes, Polyethylene PE Pipe are sorted by strength classified according to the intensity of the earlier technological developments.HDPE Pipe pressure classes that can be made between Pn4-Pn32 and the production of the desired diameter and size of Puhui Pipe manufacturer in China
The ASME Code for Pressure Pipe, in B31.4, requires hydro-test at 1.25 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
Hydro statistic pressure test of HDPE, R-PVC, C-PVC, MDPE & lateral pipes. We make twin / single barreled screw for any make or model Twin /single screw extruders. We undertake maintenance & modifiions of plastics extrusion / plastic processing machine & related works.

Pressure testing of plastic pipes, especially PE, is complied because the pipe material creeps under pressure therefore the pressure reduces without any leakage so results can be misleading. A water loss method is therefore not practical. This is true for all PE pipes PE100
