CXGJ-10M Plastic Pipe hydrostatic Testing Machine within 10Mpa Pressure burst
.Application The machine is designed and manufactured according to GB/T6111Thermoplastics pipes for the conveyance of fluids ----Resistance to internal pressure----Test method and GB/T15560Standard test method for short-time hydraulic failure and resistance to constant internal pressure of the plastics pipes for the transport of fluids . It is suitable to determine the pressure-resisting broken time or the maximum pressure value of instantaneous blast of thermoplastic pipes and compound pipes (such as PP-R ,PP-B ,PP-A ,PE ,PE-X ,PVC ,PVC-U and PVC-C ) under long-term constant internal pressure and temperature .It is indispensablefor manufacturers of plastic pipes and testing institutions . The machine meets the following standards : GB/T18742.1 Polypropylene piping systems for hot and cold water installation - Part 1 :General GB/T18742.2 Polypropylene piping systems for hot and cold water installation - Part 2 :Pipes GB/T18742.3 Polypropylene piping systems for hot and cold water installation - Part 3 :Fittings GB/T13663 Polypropylene pipes for water supply GB/T15558.1 Buried polyethylene (PE) pipes for the supply for gaseous fuels GB/T15558.2Buried polyethylene (PE) fittings for the supply for gaseous fuels GB/T18992.1 Crosslinked polyethylene (PE-X) piping systems for hot and cold water installation -Part 1 :General GB/T18992.2 Crosslinked polyethylene (PE-X) piping systems for hot and cold water installation -Part 2 :pipes GB/T10002.1 Unoplasticized polyvinyl chloride (PVC-U) pipe for water supply GB/T10002.2 Unoplasticized polyvinyl chloride (PVC-U) fitting for water supply GB/T18993.1 Chlorinated poly (vinyl chloride) piping system for hot and cold water installations -Part 1:General GB/T18993.2 Chlorinated poly (vinyl chloride) piping system for hot and cold water installations -Part 2:pipes GB/T18997.1 Polyethylene/Aluminum /polyethylene composite pressure pipe- Part 1 :PE/AL/PE pipe overlap-welded by aluminum pipe GB/T18997.2 Polyethylene/Aluminum /polyethylene composite pressure pipe- Part 2 : PE/AL/PE pipe butt-welded by aluminum pipe ISO 1167 Plastic piping systems - Thermoplastics pipes - Determination of resistance to internal pressure at constant temperature. .Feature 1.1 This instrument is used for testing a certain range of internal pressure in a long period of time of plastic pipes. 1.2 The instrument consists of a pressure host, a pressure station, a water tank, a temperature control system and a computer software system. Main Frame: It consists of pressure micro control parts, automatic filling pressure and electric discharge pressure parts, pressure micro control part adopts the microcomputer MCU control; equipped with high resolution, high speed of ∑ - delta 16-bit adc chip, real-time communication and computer; and it can automatically fill and relief pressure according to the situation of pressure. Pressure Station: Its main function is to provide pressure to the main frame, the requirement of lower limit pressure of pressure station requirement must be higher than all tested specimen. The plunger pump of the station is made in the United States (large flow, low noise, high pressure, free maintenance). Water Tank: It consists of electric opening part, self-circulation part, heating part, automatic water filling part and insulation part. Temperature Control System:Accurately control the temperature of the water tank, temperature display, set temperature individually. It can control the liquid level of tank at a reasonable position, at the same time it can also guarantee the temperature. Software System:By connecting with RS232 serial interface to the pressure on the host, it can provide the parameters setting, calibration, pressure relief, zero, amplitude modulation, drawing the test, test records and print test reports and other functions.
2 Application
The instrument is widely used in the internal pressure test of all kinds of plastic pipes. It is the ideal testing instrument for construction industry, Plastic pipe producers, national testing sectors and the scientific research sectors.
