Pressure Testing Equipment

All of the cylinder work The Cylinder Service Centre undertakes is fully tested and certificated upon completion. This is true for both newly manufactured units and refurbished ones.

The pressure testing requirements for the work that The Cylinder Service Centre undertakes are so specialised and varied that we had a real problem finding a machine that would do the job for us. So much of a problem that we ended up designing and building our own pressure testing solution.

There is always a risk in developing an in-house solution and so our pressure testing rig has been finely tuned in full consultation with the UK Health and Safety Executive.  The final result is that we now have a rig that allows us to make challenging evaluations of repaired, or newly built cylinders in an environment that is safe for our employees and visiting customer representatives alike.

As with so many other things in our business the rig continues to develop over time as we recognise the need for new facilities as technology and customer demands change.  Having both the design and technology in-house gives us the flexibility to further develop our pressure testing rig much more quickly and effectively than would be the case if we had to rely on an external manufacturer.       

Pressure Testing Rig: Technical Specification

The pressure testing rig is a fully enclosed testing cell with observation panels and pendant controls for the directional control valves.

The machine enclosure is fully interlocked which means the pumps cannot be started until the doors are closed. Upon sensing pressure, in any line, the doors are automatically locked. The interlocking mechanism has additional safety features added in so that, should the doors be forced open, the testing pumps shut down.


Pressure Testing Rig

A flashing beacon indicates testing in progress - something that is clearly visible around the workshop.

IBS cubes with quickchange connectors form the reservoir. This means that production, or operational fluids supplied by customer can be used for testing if required.

The rig has a 12 metre long bed and so is able to test cylinders up 6 metres long within the enclosure. The maximum bore size that can be tested is 400mm.

There are 2 pumps in the rig, each producing 55 litres/minute at 300 bars for standard testing on mineral oil. There are flow controls fitted to each pump for testing small cylinders at low speed with stepless adjustment down to zero flow.

Adjustable pressure control valves allow for low pressure testing which can go as low as 30 bars.

The pumps are normally run independently enabling both ends of the rig to be used simultaneously, but the flows can be combined for fast fill of large cylinders.

The rig also has an integrated intensifier producing up to 1400 bar for HP jacking cylinders.

For testing cylinders with fire resistant fluids, the rig has an integrated power unit.

Pneumatic Cylinders

Pneumatic testing can also be carried out within the enclosure.
