Hydrostatic testing units, ultra high pressure testing units, testers and other pressure testing system for strength test, tightness test, destructive test and fatigue test up to 4000 bar.

CHARACTERISTICS

• main application for hydrostatic pressure tests: strength, tightness, destruction, non-destruction and fatigue tests
• Most of these are tailore-made devices = design based on exact customer requirements even for the most demanding operations
• Complicated systems for controlled pressure test according to regulations (ČSN, API, DIN, etc.):
  • gradually or jump increase and decrease of pressure with continuous delays and maintenance according to prescribed pressure test process
• High pressure test unit adapted for end-user comfort, easy maintenance and service
• Control: automatic, semi-automatic, manual
• Delivery → Installation → Testing → Commissioning → Operator (End-user) Training → Periodic checks and service 

APPLICATIONS

• strength / tightness (leakage) pressure tests,
• hydrostatic / hydrodynamic tests
• destruction and non-destruction testing
• fatigue tests
• Pressure testing of high pressure pipes and piping systems
• Pressure testing of tubes and heat exchangers
• Pressure testing of castings, fittings, valves, pumps
• Pressure testing of tanks (aerators, wind turbines, expanders, storage tanks, water heaters, drainage tanks, venting tanks, etc.)
• Pressure tests for high pressure cylinder (gas or oxygen bottles)
• Pressure tests of firefighter's equipments
• Pressure tests of steam turbines, steam boilers and biomass boilers
• Pressure testing of hydraulic systems
• Pressure testing of other products

DESCRIPTION

Pump

• Pressure testing units up to 500 bar are mostly assembled with SPECK TRIPLEX pumps
• High pressure testing units up to 1500 bar with our own production AQH pumps
• Ultra high pressure testing units up to 4000 bar with pneumatically driven pumps (multipliers) MAXIMATOR

Pressure and flow control

• Flow and pressure control from 0 to the maximum required by the customer is provided mainly by:
  • Lifting of intake valves manually or pneumatically in combination with frequency converter or diesel engine speed control
  • Pneumatically controlled regulator,
  • Spring regulator,
  • Control by hydro coupling
  • by inserting a speed variator
  • or a combination of the above mentioned

Unit control

• classic control via power switch with dry run protection
• sophisticated control systems adapted to specific requirements
  • systems are able to monitor all unit operating states and ensure fully automatic operation and pressurization according to the pre-selected process 
  • pressure tests can be monitored on the PLC display and also pressure test records could be taken 
• The remote control of the unit - the ability to track and control the whole process of the pressure tests from a safe distance

Construction

• Stationary
• Mobile
  • up to 60kg usually placed on a common frame with a suitable attachment
  • over 60kg usually assembled on common frame with wheels, built into cars, on trailers, etc.
