These joints are unrestrained against pressure thrust
& are for use in correctly anchored & guided straight line
systems.
Axial
Expansion Joints
Sizes available: 25mm to 4.5metre
N.B. Pressure Ranges: upto 16kg/cm2 (special units for
high pressures)
These are the simplest form manufactured from single and
multi-ply elements and fitted with either flanges or pipe
ends connection. These units are suitable for axial movements
only, though in certain cases will take care of small lateral
offset.
Twin
Expansion Joints
Sizes available: 25mm to 4.5metre N.B.
Pressure Ranges: upto 2.5kg/cm2 & above.
Two bellows elements joined together by a center tube fitted
with pipe ends or flanges. Capable of both axial & lateral
movements because of tube instability & is limited to
low pressure applications.
