Installation Steps

Cut Your Pipe To Size

Cut Your Pipe To Size

Cut your pipe cleanly across the tube diameter using a good quality pipe cutter or rotary pipe cutter.

Cut Your Pipe Accurately

Cut Your Pipe Accurately

It is important to ensure that the pipe ends are clean and cut square. Failure to do so could impact on the quality of your jointing. If your cut is not flat, or your pipe is too short, the pipe may not hit the pipe stop compromising the joint integrity. Too long and you may introduce strain into the whole system.

Clean The Socket Of The Pipe

Clean The Socket Of The Pipe

Using your deburring tool, make sure the inside of the pipe is smooth and will not interfere with the flow.

Clean The Outside Of The Pipe

Clean The Outside Of The Pipe

Clean the outside of the pipe, making sure that there is no pipe residue, dirt or grit is present near the joint. Failure to remove all oxides and any material where the fittings and tube overlap can interfere with the capillary action and thus will reduce the strength of the soldered joint, resulting in failure.

To the same effect, over zealous cleaning can result in too much material being removed, resulting in a loose fit and failure.

Testing Your Installation

Flowflex products are designed to comply with normal installation specifications, such as BS 806-4. As such, we strongly recommend that all systems are thoroughly tested upon completion. Whenever possible, completed systems should also be flushed to remove any debris, ensuring optimal performance and longevity.

Testing Hydraulic Installations

For hydraulic-based installations, the system should be tested to 1.65 times the system’s maximum operating pressure. This pressure should be maintained for at least 30 minutes to help identify any potential issues and confirms the system’s integrity.

If higher test pressures are required for your specific application, please contact us for further guidance and support.
