Hydrostatic pressure testing equipmemt used for plastic pipes
according to ISO 4427
Ⅰ. Outline:
Hydrostatic pressure testing equipmemt used for plastic pipes
according to ISO 4427 is suitable for the determination of the
damage resistance time of thermoplastic pipes under the condition
of instantaneous hydraulic blasting of pipes and long-term constant
pressure. It is an indispensable testing instrument for scientific
research institutes, quality inspection departments and pipe
manufacturers. The hydrostatic testing machine uses computer
embedded control. Modular design for individual control. If there
is a problem in any way, as long as the stop valve of the current
station is closed, it will not affect the normal operation of other
stations. It has pipe rupture identification, real-time monitoring,
call data recovery, printing, storage test results, sample
pre-processing settings. Such functions, and according to the needs
of national holidays, can store up to 7 days of data. The machine
is widely used in internal pressure-resistance tests of various
plastic pipes .It is an ideal testing equipment for building
materials industry ,pipe manufacturing factories ,national
inspection departments and scientific research departments.
Ⅱ. System Feature:
1. Industrial tablet control, direct control.
2. The machine with "precision pressure control unit" multi-channel
combination.
3. Each station is independently controlled no interference.
4. 5-statiions, 10-stations, 15-stations, 20-stations and other
multi-station optional, up to 60 stations and above. With a
hydrostatic test, blasting test.
5. Max. pressure: 10,16,20, 30MPa ...
6. Pipe diameter range: Φ16 ~ 2000mm can customized.
7. Perfect test system on the burst, pressure maintaining, pressure
relief, overvoltage, operation, the end of the leak, rupture eight
test states to make accurate analysis and judgment, with real-time
monitoring, data storage.
8. Power protection, test report storage / print output and other
functions. Automatically determine the effective time, invalid
time, the remaining time and other parameters, to prevent the
evening, holidays and other periods of failure time, invalid time.
9. When power-down time ensure that the test is accurate and smooth
completion. Instrument structure is reasonable, stable performance,
easy operation, display intuitive.
10. Rich software interface (multi-language environment to meet
customers in different countries and regions.
Ⅲ. Meet standards
ASTM D1598-2015 Standard Test Method for Time-to-Failure of Plastic
Pipe Under Constant Internal Pressure
