Tapered flexible connections

Tapered flexible connections for connecting barrels on weighing cells, mixers or dosing devices with supply lines, discharge lines or other forms of air transport or powder transport with different connection diameters. When connecting two different pipe diameters, it may be desirable to fit a tapered flexible connection, also called a step bellows or conical flexible connection.

Conical and tapered flexible connections are now seamlessly available in many sizes and shapes. The tapers have no seams, which reduces the hygiene risks. Expansion joints with two different connection diameters are more flexible than cylindrical ones. This makes them ideal for weighing or dosing equipment.

Manufacturing engineering

Depending on the diameter, a range of different techniques can be used to produce a tapered flexible connection. Although a tapered flexible connection cannot be extruded like a silicone bellows, the number of welds can be reduced to a minimum by using the latest production techniques. This offers Euro Manchetten even more possibilities to make a flexible connection as flexible as possible. Different welding techniques can be applied, adapted to the customer’s wishes, but usually high frequency welding is chosen, whereby seams can also be welded hygienically in consultation with the customer.
