UNISIG – Flange Mounted Product: Pig Signaller Grouping: Pressure vessel Version: 1.0 General function and application: Pig signallers are fitted to launcher and receiver stations to confirm the launch / arrival of a pig. They can also be at any location along a pipeline length to give indication of a pig at a specific location, e.g. road and rail crossings. Also, other pipeline features such as valve stations, bends and tees. They can be used to detect the passage of all types of pigs from foams, spheres, and metal-bodied pigs to intelligent inspection tools. Offers a cost effective, reliable signalling system. Incorporating a simple magnetic / mechanical design, which reduces the number of moving parts. This reduces initial capital costs, running and maintenance costs and in-turn; down time of your pipeline. The design incorporates a unique magnetic system, which allows for the use of static seals. This means reduced risk of In addition to being deigned for manufacture, to keep costs to a minimum, the PE UNISIG is also designed for ease of operation, therefore is simple to use and maintenance can be carried out in a fraction of the time of older designs. With this in mind PE has designed the standard Flange mounted unit to be removed under pressure, without the need for an isolation valve, when used with PE Removal Tool. Many leading operators have chosen the PE UNISIG to standardise on due to its simple design and inter-changeability of parts due to the modular configuration.
