Probe Insertion
Psl provide a complete Probe Insertion service. We can provide the facility so new internal probes can be installed into the existing live and running pipe systems.
This method saves downtime, money and without the need to drain down the system. It is also a quick and effective method used for gaining accurate flow or temperature measurement on steel pipework of an size.

How Probe Insertion Works
First a bespoke steel saddle must be machined by our specialist supplier. This is made to the exact size, shape and thread of the probes you wish to install. These probes are then brought to site by PSL and welded onto the external surface of the pipe.
A temporary ball valve is installed to the external thread of the saddle and wound on until tight. At this point we pressure test then new weld, to ensure before we drill that, there will be no leaks or problems.

A Hot Tap is then carried out, to drill the correct size hole in the pipe wall. This is carried out as per the procedure, which is explained in our Hot Tapping Guide on the downloads page. Once complete the hot tap rig is exchanged for our probe insertion tool.
This allows us to use a socket and ratchet to wind the new probe into the internal thread of the saddle, whilst containing the system pressure and contents. This process is without the loss of any fluid. Once tight the temporary ball valve is removed and the process is complete. Then it’s ready for you to install your measuring equipment and start taking readings straight away.
