A fitting is a component of a pipeline that connects
sections of pipes. Primarily, fittings are used to
create branches, transitions between different
diameters—either increasing or decreasing—, for making
turns at various angles, as well as for the
straight-line connection of individual pipes. No matter
how many types of pipes are produced today, regardless
of the material from which they are made, the same
number of fittings is produced for each type of pipe in
terms of usage.
