● Precautions on Selection
To prevent the siphon pipe from falling out of the internal pipe and into the roll due to loosening of
the screw A, the thread direction of the screw A must be "left-hand thread when the direction ofrotation of the roll is clockwise" or "right-hand thread when it is counterclockwise" as viewed fromthe side from which the product is installed.

Determine the length of the hanging pipe to be installed to thread A by considering the internal pipe
deflection. If the hanging pipe is inappropriately long, the hanging pipe may contact the roll, resulting
in abnormal noise, product damage, injury to workers, or damage to surrounding equipment. If thehanging pipe is inappropriately short, it may not be as effective as expected in collecting drain inthe roll.

Flexible Metal TubeApplication) Used for connection between a rotary joint and a stationary pipe.
Order )

Please provide information on the fluid, temperature, pressure, size, length,
fitting shapes on both sides, and material.

● Fitting Shapes and Materials
1) Three types of fitting shapes are available: union (U), nipple (Ni), or flange (F).
2) Two types of fitting materials are available: FCMB and SUS.
3) The material of the tube and blade is stainless steel.

Union (U)Nipple (Ni)Flange (F)● Combination Example
In addition to the UU or NiU type, the FU, FF, or NiF type is available.

UU typeNiU type● Precautions for Selection and Use1) Union (U) and nipple (Ni) have a taper pipe thread (JIS B 0203).
2) Flanges (F) that conform to JIS, ANSI, or JPI standards, etc. are available.
3) Select the tube length with reference to Table 1.
4) When installing a flexible metal tube, slightly bend it in the rotation direction of roll.
Furthermore, carry out pipe laying work so that excessive “tension”, “compression”, “torsion”,
or “bending” is not caused. See the rotary joint instruction manual for more information.
5) Bend the tube so that the bending radius is not less than the smallest bending radius shown in Table 2.
6) As a flexible metal tube is a metal, it may suffer from metal fatigue. Replace it periodically.
If you have any questions, contact our sales representative.
