Pipe parts - fittings
A large variety of pipe parts can be found, espe-cially for PE and PVC pipes (Fig. 2.4). Various bends or elbows are normally used in aquaculture. T-pipes are also used to connect different pipes.
Different conversion parts allow the connection of pipes or equipment with different diameters. Sockets, flanges or unions are used to connect pipes or pipe parts. Sometimes end-caps are used to close pipes that are out of use. A particularly useful part is the repair socket which allows connection of an additional pipe (a T-pipe) to a pipeline where the water in the installation flows continuously, which means that connections can be made to pipelines that are in use.
