W1 20 M08 When choosing the right IDEAL-MAXI hose clamp, it is important first to establish which environmental conditions are expected and also what the requirements are regarding corrosion resistance. The material qualities available range from zinc-plated clamps with the designation W1 to IDEAL-MAXI clamps made of chrome nickel steel with the designation W5.
M08 The next step involves establishing the external diameter of the connecting elements. The 3-character designation denotes the largest diameter for which each IDEAL-MAXI hose clamp is designed. This also denotes the internal diameter of the IDEAL-MAXI hose clamp as supplied. All IDEAL-MAXI hose clamps have a large clamping range. The closely graduated IDEAL-MAXI range allows for the assembly time, i.e. the screwing operation required to adjust the diameter, to be kept as short as possible and the overhang of the band end to be limited.
20 Finally, the required clamping force has to be determined and also the contact pressure that is appropriate for the relevant hose connection. How robust does the IDEAL-MAXI hose clamp have to be for the specific application?
W1 All components made of zinc-plated steel. Low level of corrosion resistance. CrVI-free
Band: Steel, zinc-plated
Casing: Steel, zinc-plated
Screw: Steel, zinc-plated, blue passivated
Screw head type: slotted hex head screw SW 13 mm with integrated Phillips head
W5 All components made of chrome-nickel molybdenum steel (1.4401) (V4A). Highest level of corrosion resistance (seawater resistant). Highly magnetisable.
Band thickness 1.50 mm A 1.50 mm thick band steel with the IDEAL-MAXI hose clamp provides for a secure screw and band guidance for the transmission of a high clamping force. As a result, the greatest breaking torques are achieved at the same time at low-level idle torques. In combination with the comparatively low-level friction and the worm drive, this results in a high clamping force.
Threaded bands:
Band thickness 1.00 mm A band thickness of 1.00 mm allows for the transmission of a greater clamping force, which derives from the particularly stable design of the engraved thread (which has been specially adapted to suit the special screw thread). At the same time, the selected materials ensure a high level of elasticity and therefore a good interlocking attachment with the external diameter of the hose.
