Expansion joint
HUWA international

If a pipeline is subject to a change in length caused by a
change in temperature of the surroundings, by the medium
or if these changes are caused by other circumstances, such
as sinking of the support, the Huwa Expansion Joint is the
ideal tool to absorb forces caused by the change of length.
The HUWA Expansion Joint is a sliding type which is sealed
by a long packing tube. The great advantage of this design
is that one expansion joint is able to change its length up
to 250 mm. Another advantage is that any type of packing
can be used which allows the HUWA Expansion Joint to be
engineered for any medium.
The HUWA Expansion Joint can be supplied in a normal
diameter of 50 mm up to 600 mm in AISI 304 stainless steel
with standard a synthetic Tefl on impregnated packing to
minimize maintenance. The Expansion Joint is available with
fl anges or pipe ends that are bevelled for welding also they
can be ordered with a restriction device. Once fabricated
the stainless steel expansion joint is stained and fully passivated,
to obtain the highest possible degree of corrosion
resistance.
As the HUWA Expansion Joint is engineered for each application,
requirements such as special lengths, alternative materials
or special packing can be incorporated in the design.
