Structure and material

 
[Ground use]                                                  　[For buried]

[The above diagram shows KA100. ]

*Flanges are hot-dip galvanized for ground use and hot-dip galvanized + black epoxy resin paint for underground use as standard.

Dimensions and performance table

※1. All 40A and below are solid type arches. Click here for solid type arch (arch filling rubber) .
※2. Displacement over 50A is the value for cavity type arch. For solid type arches, multiply the values ​​in the table above by 0.5 for shrinkage and 0.6 for elongation. (The amount of eccentricity does not change.)
※3. Each displacement amount is the value when each is displaced independently.
※4. The amount of eccentricity for slanted piping differs from the above values, so please contact us each time.
※5. Mass is a guideline.
※6. The inside diameter of the mouth of 25A or less is R-processed.

Option

<Remarks/Precautions>

• If necessary, use the control unit ( here ).
• If the fluid is gas, the maximum working pressure will be 1/2 of the above value.
• Please contact us for non-standard specifications (diameter, length, etc.).
• Due to the manufacturing method, the plating on the flange may be discolored or mottled, but this does not affect performance.
