Water Pipe
Pipes and Pressure

Valves are used in our daily lives to control, direct or regulate the flow of gases or liquids. By opening, closing, or varying anywhere in between - we can control anything from a manufacturing plant’s production to the kitchen faucet in our homes. 

The ability of a valve to hold pressure and be fitted with pipes or other fittings is important for it to carry out its function. Hydrostatic test, endurance test, hydraulic shut-off, leakage and dimension are some of the tests important to ascertain the finality of a valve.

Some of the fixtures for display, mounting and testing are not readily available off the shelf. As testing professionals, we have designed and built jigs and fixtures for our own testing purposes over the years.


These testing jigs and fixtures not only fulfil various international standards and requirements, but as users of these jigs and fixtures ourselves, we are able to see it from the users' perspective and incorporate user-friendliness into our designs.

Depending on your needs, we can build complicated designs at low costs and resolve any technical issues that may arise. Our clients include product suppliers, product showrooms, testing laboratories etc.
