High corrugated rubber bellow with reinforcement and shaped solid rubber flanges, self-sealing (no additional seals required). Suitable for backing flanges with a supporting shoulder.

Flange versionBoth sides with backing flange made of galvanized steel with clearance holes, drilled according to DIN PN 10 (standard). Other materials and dimensions are possible.

Pressure resistanceDesign according to customer specification, max 40 bar operating pressure. Vacuum resistanceOnly vacuum-resistant with a vacuum supporting ring.

DN 200 bis DN 5000Type 40 is a high-corrugated, highly elastic rubber expansion joint. Due to its corrugation it has very low inherent resistance. It is characterised by its ability to absorb a large amount of movement in any direction. The type and amount of corrugation, installation length and material strength of this type can all be tailored to your requirements. There are also a large number of rubber qualities available, which means that you can select a suitable rubber compound for any application (see the material descriptions on the following pages).Type 40 is mainly used in large industrial plants and power plants, where it compensates offsetting and compression, insulates vibration and absorbs pipe movement.

Type 40 is a rubber expansion joint that is only vacuum-resistant to a small degree, so a suitable vacuum sup-porting ring should be used on underpressure.

Standard material: 1.4571

An alternative design with a vulcanised vacuum supporting ring is also available. Please note that greater stiffness rates must be taken into account and that the axial and lateral movement will be reduced.

Vulcanised supporing ring (example)

Please take the limited movement into

account.

Type 40 is produced with pressure-resistant solid rubber flanges. In order to ensure a tight connection to the pipe/fan, the counter flange should be flat

and have no seal. If this is not possible, the expansion joint flange can be produced with a negative recess (see Version 2) in order to accommodate the

raised face of the counter flange and ensure a flat connection. Alternatively, spacer rings can be used (Version 3).

Design E - with tie rodsFor absorbing the expansion joint’s reaction force in the direction of expansion while also absorbing great lateral movement.

The use of PTFE-coated spherical wash-ers and conical sockets reduces the frictional force considerably during lateral movement. Can be used for vibration insulation and absorbing lateral move-

ment.Note: The number of tie rods is calculated corresponding to the available design data.

OTHER DESIGNS

Design M - with tie rods/thrust limitersFor absorbing the expansion joint’s reaction force in the direction of expansion while also absorbing high lateral movement and preventing the

bellow from strong compression. The use of PTFE-coated spherical washers and conical sockets reduces the frictional force considerably during lateral movement. Can be used for vibration insulation and absorbing

lateral movement. Note: The number of tie rods is calculated corresponding to the available design data.

8 / 12 www.belman.com

BG08/2018 –Subject to alterations and misprints

Design F - with hingeFor absorbing angular movement in a single plane while guiding pipes. The hingeabsorb the reaction forces so

that the fixed point only needs to absorb the adjusting movement. Usually two hinge expansion joints are fitted with an intermediate pipe to

achieve a high level of lateral move-ment (see the example in the technical appendix).

Multi-corrugated bellow designs Different corrugation geometries and

bellow forms (single and multi-corrugat-ed) are available, in order to absorb high

axial, lateral and angular movement.

Example - double corrugation, Design A - with-out tie rods
