Flexible Connections

Adapters

Besides reducers we produce adapters. The adapters have for instance a round connection at one side and a square connection at the other side. The change in shape from round to square will cause more wear than normal. By giving the adapter a bigger wallthickness and, by using high abrasion resistant polymers, our adapters will have an extended lifetime.

Pre-shaped rubber bends

Steel bends are in various material handling systems a problem since wear will shorten the lifetime of the bend. Trelleborg Velp produces a wide range of pre-shaped rubber bends. The bends can be used in suction and discharge applications in various diameters and radii. The bends can be provided with several flange connections and the outer curve of the bend will have a thick abrasion resistant inner tube. We also produce conical preshaped rubber bends as where the reduction in diameter can be over the whole length of the bend or over a part of it.

Expansion pieces

Compensators and expansion joints. Our compensators, are used in various applications, for example to compensate for big displacements in piping systems or as flexible joints in lines inside ships or process plants. The compensators can be equipped with all the types of flanges mentioned before. The rubber used for the inner and outer layers is chosen with full regard to the working conditions.

Y-pieces

Steel y-pieces are very sensitive for wear when carrying abrasive slurry. By making the y-pieces out of rubber and cord material the wear properties are much better than steel and lifetime will exceed the lifetime of a steel y-piece. Misalignment of steel pipes can easily be compensated by a y-piece since this rubber piece is much more flexible than steel

Pinch valves

There are different constructions of pinch valves. All constructions use a rubber hose that is squeezed in the middle. This will vary the flow of the medium or completely stop the flow. We produce different kinds of hoses for these valves and they can be produced with or without a flange connection.

Hoses for sewage systems

Our flexible hoses for sewage systems are used as flexible connection between a fixed point and the sewage line. The hoses can be delivered in large diameters and have incorporated steel rings or a steel wire to prevent the hose for collapsing caused by vacuum or the weight of the earth that is above the hose.
