Hachiken KL Low Reaction Force Flexible Tube
Made in Japan
Manufacturer : Hachiken
Model : KL
Low reaction force flexible tube
A flexible tube with a low reaction force design. The reaction force during displacement is about half that of the flexible tube (KA).
Feature
Since the reaction force at the time of displacement is small, the piping is less likely to be damaged.
Kinds
- KL100: 100mm for eccentricity (for above ground and buried) 3 threads
- KL200: 200mm for eccentricity (for above ground and buried) 4 threads
Usage
- Connection of resin piping such as PVC
Standard specifications
- Maximum operating temperature : -10 to 60°C
- Maximum operating pressure : <Negative pressure>
See the performance table for ground use -90kPa <Internal pressure> - See the performance table for underground use
- Installation conditions for burial use :burial depth 1 to 3m, vehicle weight 25t
- Flange standard : JIS 10K
- Inner rubber material : EPDM
Structure and material
[Ground Used] [For Buried]
[The above diagram shows KL100. ]
| Part number | Name | Material |
| 1 | Inner rubber | EPDM |
| 2 | Reinforcing layer | Synthetic fiber |
| 3 | Body reinforcement layer | Steel wire or synthetic fiber |
| 4 | External rubber | Synthetic rubber |
| 5 | Flange | SS* |
| 6 | Reinforcement ring | SS |
| 7 | Reinforcement pipe | SS |
*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
* Please inquire separately about sizes from 550A to 1000A.
※1. All 40A and below are solid type arches. Click here for solid type arch (arch filling rubber) .
※2. Displacement 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.
Option
* If this product is made into a rubber embedded specification (solid), the reaction force will increase significantly.
| Standard | Option | |
| Flange standard | JIS 10K | Tap water F12, JIS 5K, JPI class 150, etc. |
| Flange material | SS plating | SUS304, SUS316, etc. |
| Inner rubber material | EPDM | CR, NBR, NR, wear resistant |
<Caution>
This product has a larger thrust force when pressurized than general joints. The use of safety bolts) is particularly strongly recommended.
<Remarks/Precautions>
- Please note that the maximum working pressure is lower than the standard flexible tube.
- If necessary, use the control unit ( here ).
- 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.
- When the fluid is gas, the maximum working pressure is 1/2 of the catalog.
