Notice
-
The data in this catalog uses values in a straight hose configuration.
-
The permissible pressure is not the maximum operating pressure. Please refer to the “Operating Pressure Design Table” in the hose handling precautions and configure according to the operating pressure (normal working pressure). Also, please note that the combination of fittings and clamps, operating temperature, and bending conditions may affect performance.
TOTAKU LINE POWER-AT
Features
-
Exceptional pressure resistance with an allowable pressure of 145 psi (1.00 MPa) at normal temperature, built to minimize stretch under pressure.
-
Outstanding durability.
-
Engineered to withstand external pressure with minimal deformation.
Applications
-
Suction and discharge of muddy water in civil engineering projects.
-
Suction and discharge of materials like sand, gravel, and sludge.
-
Ideal for dredging and land reclamation work.
-
Suction and discharge of powdered and granular materials, such as cement.
-
Transport of high-viscosity substances and transfer over long vertical distances.
Cautions
-
Avoid long-term storage outdoors, as this may cause cracks to form due to ozone degradation.
Standard Dimensions and Properties
The TOTAKU Power Band can be installed on-site.
(For 8 in (ϕ200), crimping is recommended for added safety.)
-
Pre-install the TOTAKU Power Band onto the hose, and then insert the fitting.
-
Use a torque wrench to tighten the bolts. Be cautious not to overtighten, as it could damage the hose.
Note: For on-site installation, take safety precautions to prevent accidents caused by fittings becoming loose. It is recommended to secure the TOTAKU Power Band to the flange or connection points using wire or binding materials.
Tightening Torque
-
2 in (ϕ50), 2.5 in (ϕ65): 10.84 lb-ft (14.7 N·m)
-
3 in (ϕ75): 14.46 lb-ft (19.6 N·m)
-
4 in (ϕ100), 5 in (ϕ125): 18.07 lb-ft (24.5 N·m)
-
6 in (ϕ150), 8 in (ϕ200): 21.69 lb-ft (29.4 N·m)
Operating Temperature Range:
°F: 14 to 122
°C: -10 to 50
Notes:
-
The permissible pressure varies with operating temperature.
-
Operating down to a vacuum level of approximately -29.5 inHg (-0.1 MPa) is feasible at room temperature.
SHIMETAC for LINE POWER-AT
Applicable Sizes: 2 in (φ50 mm) to 6in (φ150mm)
Features
-
The allowable pressure with a SHIMETAC connection matches the allowable pressure of the hose itself.
Fittings can be easily attached and removed on-site.
Notes
-
Be sure to use the dedicated fittings for SHIMETAC.
The fittings shown below are examples.
