Precautions before installation
Caution
1. rovide anchors, guides, and pipe supporting device when installing the product.
*The function of the product will not be fulfilled due to
equipment breakage, piping bending,
abnormal product growth, etc.
2. lease use the product within the range from the minimum length to the maximum length.
*
If the product is not within the specified range, the product will not function due to abnormal
expansion and contraction of the product.
3. Install the product correctly so that the inlet and outlet
are correct. There is a display on the
body showing the direction of fluid flow.
*Installation in the wrong direction may not only affect the original performanc
e, but may also
lead to an accident.
4. Install so that there is no misalignment in both horizontal and vertical piping.
*
Misalignment may lead to noise or damage from the inner cylinder, which may not only affect
the original performance, but may also lea
d to an accident. In particular, vertical piping is
prone to misalignment, so provide anchors, guides, and pipe supporting device
to prevent
misalignment.
(1) The expansion/contraction of piping depends significantly on temperature. To ensure satisfactory
results, use the expansion joints within the maximum expansion/contraction length.
(2) Secure anchors and guides are required to make full use of the function of the joint connected
to piping.
(3) The piping system shall be equipped with main anchors at the following positions. (Refer to the
reference piping example on page 5.)
[1] End part of straight piping with shut-off plate.
[2] Portion of bent pipe where the flow direction changes.
[3] The portion between two expansion joints where the piping systems are changed by
reducer.
[4] The portion of piping between two expansion joints where a valve is installed.
[5] The entrance of a side branch containing an unrestrained expansion joint into the main
piping.
(4) Using a sufficient number of anchors and guides is important not only for guiding the piping to
absorb its expansion or contraction with the joints, but also for preventing pipe bending or
buckling or joint damage. Check where anchors and guides should be installed, and mount them
according to the correct procedure.

Installing anchors, guides and pipe supporting device
4.1 Load acting on the main anchor of straight pipe
Mount a main anchor at both ends of the piping, each branch point, and the location where a
reducer or valve is installed. These main anchors need to be strong enough to withstand the
force required to stretch or contract the sleeve plus the internal pressure thrust resulting from
the effect of the internal fluid pressure.

4.3 Load acting on the main anchor of curved pipe
Mount a main anchor at each point where the piping changes its direction.
The thrust works in two different directions and becomes a resultant vector of two thrusts.
········ (C)
4.4 Load acting on intermediate anchors
An intermediate anchor is required when two or more joints are mounted between main anchors.
Intermediate anchors should be strong enough to withstand the force required to expand or
contract the sleeve, the frictional force of pipe guides, and other loads.
FIA = (FM1+FG1) [upstream side] - (FM2+FG2) [downstream side] ············ (D)
On the up and downstream sides of an intermediate anchor, when the pipes connected are
equal in diameter and numbers of guide elements on both sides are the same FM2 and FG2 are
equal to FM1 and FG1 respectively, but opposite in sign, and the load acting on the intermediate
anchor is zero, i.e. FIA = 0. However, in some case, the pipe line is heated gradually from one
side, and as a result, one side of the pipe expands more than the other side.
Therefore, when FIA = 0, it is necessary to add the load acting from either the upstream side or
the downstream side to the load considered in general piping design.
FIA＝FM1＋FG1······················ (E)
4.5 Caution on vertical piping
In case of vertical piping, the piping mass and fluid mass are further loaded, so when
calculating the anchor strength, add them together. Make sure to install the product with no
misalignment of the piping. Misalignment may lead to noise or damage from the sleeve.

Installation interval of
guide
elements for axial movements
In a piping using expansion joints for absorbing axial movements, guide elements (G) shall be
installed to align the pipe joint and pipe and transmit the force necessary for axial movement
smoothly to the anchor.
As given in figure 1, the installation intervals of respective guide elements such as the interval (L1)
from the expansion joints to No.1 guide element, the interval (L2) to No.2 guide element and the
interval (L3) to the intermediate guide elements shall not exceed the interval values obtained from
formula (F) to (H) shown in the following [1] to [3].
Keep the misalignment of 125A and smaller piping within ± 2 mm and that of 150A and larger
piping within ±3 mm. Adjust the parallelism of piping to ±0.5˚ or less.
As to the pipings using carbon steel pipes for pressure pipings, when the expansion joints only for
axial movement are used, the intervals of intermediate guide elements may be obtained from figure
2 instead of the calculation by formula (H).

7.2 Adjustment of attaching face-to-face dimension
Since the thermal expansion of piping is absorbed by the contraction of the expansion joint,
and the thermal contraction is absorbed by the extension of the expansion joint, prior to
attaching the expansion joint, the attaching face-to-face length shall be obtained by formula
(K), considering the preset amount from the site air temperature, working temperature range
and the maximum axial movement.
