tie rods to support the thrust due to internal pressure.
TERMINALS
We can produce expansion joints complete
of flanges and to be pipe ends. The different terminal are generally produced in carbon steel. On request, it is possible to use stainless steel. Standard flanges are bored according to UNI - ANSI rules, or special and in above mentioned materials.
SLEEVE
To avoid direct contact between bellow and fluid a sleeve is welded on the internal side of the expansion joint. It allows to reduce thermal strains, to reduce loss of head, turbulences and erosion.
EXTERNAL PROTECTION
To protect waves from foreign bodies or to facilitate the application of the insulation,
bellow, can externally be wound by a plate, generally in carbon steel.
REINFORCING RINGS
When we have to plan a bellow subjected
to high pressure it is necessary to use reinforcing rings made of carbon steel sheet. Besides uniformly distributing the
compensator, they also act like run limiting
devices.
