Application
Expansion joint to compensate changes in
pipe length, caused by temperature changes in pipe systems. For use with
non-aggressive
fluids, water, vapors and gases, for service
pressures and temperatures:
Technical description
A moveable part is inserted into the cast iron
body. Gland packing around the body
provides the seal. Guiding rings ensure
movement along the axis of pipe-line.
Connecting and face-to-face dimensions
Face-to-face dimensions are given in the table
below.
Flange connection dimensions as per
DIN 2501.
Flange faces as per DIN 2526, Form C.
Material
Body and packing bonnet
carbon steel ( GS-C25)
Pipe of moveable part
stainless steel (13Cr)
Flange of moveable part carbon steel
Guiding rings stainless steel
Gland packing asbestos-free fibre
Testing
The gland expansion joint is tested as per
DIN 3230-3, ČSN 13 3060, part 2.
Installation
The expansion joint can be installed in
horizontal or vertical pipe-line. When
installed vertically the moveable part should
be uppermost. During installation it is
essential to set the face-to-face dimensions
correctly to make sure that the possible
expansion (contraction) of the pipeline is
within the allowable contraction (expansion)
limits of the expansion joint.
