Hydrostatic Pressure Tester and Hydrostatic Testing

DW5011 Hydrostatic Pressure Tester is mainly used to determine the resistance of thermoplastics pipes and short-time hydraulic burst to constant internal water pressure at constant temperature. It is applicable to thermoplastic pipes intended for the conveyance of fluids. It is suited to various pipe specimens. Today we will tell this hydrostatic pressure tester chief componen.t

Part I  Pressure Controller

Features:

1. With the functions of specimen pre-treatment, real time monitoring，test data storage, data power-off protection (memory) and recovering when powered on, etc.
2. Itis intelligent to distinguish the size and material of specimen, then provide perfect pressure rising solution and algorithm.
3. For the pipes with big rate of expansionhas the properties of rapid pressure rising rate and steady at constant temperature.
4. Self-developed solenoid valve greatly raises its working life, further maintenance is not needed.
5. Friendly display interface providesmulti languages to meet the requirements of customers all the world.
6. Protective measures are from electric part, mechanicalpart as well as software.
7. Testing data memory time for pressure control unit: 7 days (offline).

Part II  Pressure Supply Unit

• One independent pressure supply unit can be connected to several pressure control units;
• With the property of high pressure and capacity;
• Wide range of pressure and pressure can be set at any level(0-100bar);
• Automatic water compensation to avoid the pump being damage due to lack of water;
• Low noise;
• Protection system for electricity leakage or water shortage.

Part III  Water tank

• Internal part material is stainless steel and equippedwith stainless steel pump.
• With excellentthermal insulation properties, even when the water temperature up to 95 ℃ the outer cover is still at room temperature. It helps to enhance the security and save more than 70% of power consumption.
• Unique design of steam gathering device, solves the problem of steam overflow from the water tank.
• Structural bracing frame provides excellent supporting capacity and anti-deforming capacity
• Cover open: pneumaticcontrol, opening degree can be adjusted according to customer’s requirement.
• Automatic water level control,if the water level is lower than pre-set value, it will be re-established automatically by introducing water in a way that the preset temperature will not fluctuate too much (fluctuation is less than 0.1℃).
• It is possible to provide multi-stations/groups and equippedwith water filling device for big or small pipes.

Part IV  End caps

End caps is designed for internal hydrostatic pressure testing of pipes and fittings. It is used to seal the sample in order to generate internal pressure in the sample, with the characters of :

• Patented structure ensures easy mounting and perfect sealing.Split type clamps help to realize automatic centering.
• Material: stainless steel , which will not be rust even in water at 95℃.
• Hollow-out design makes it lighter in weight, easier for observation and operation. For example, Single-end weight （after assembly） of DN400 end caps less than 50kg and the weight of clamps is 7.3kg.
• End caps are produced with a specific depth from O-ring to the internal bottom which ensures that even on chamfered and oval PE pipes.
• Stainless steel chain is used to connect upper and lower end caps, to avoid the lower one go down to the bottom of water thank if specimen brittle rupture.
• There is air release valve to discharge the air left in the pipe.
• Air resource inlet and drain port are introduced to drain water after testing for big diameter end caps.

ENDCAPS: Modularized design and batch production
