Rectangular Expansion Joints

Rectangular metal bellows expansion joint adopts rectangular cross-section with rounded waveform, and a single expansion joint in the pipeline can bear displacement in two-dimensional direction. The elbow pipe duct composed of 2 expansion joints can withstand three-dimensional directional displacement. Rectangular rounded corrugated metal expansion joint has full height, half height type, according to the size of the flue, the stress strain requirements of the user can choose multiple wave sections.

1.After the user has selected a suitable compensator according to the thermal displacement of the pipe system, he must at least provide the flow medium in the pipe, the design pressure of the flue, the maximum temperature during operation, the shape size of the cross-section of the flue (length, width) the waveform selected (full height 216mm, half height 108mm) and the number of waves (the number of single waves of a single corrugation does not exceed 6 waves) in order to carry out the structural design and manufacture of the compensator.

2.Maximum allowable expansion per wave: full-height △α=±24mm half-height △α=±12mm.

3.Ash-blocking plate: the duct or the pipe with less dust can be used without it, and the flue with more dust should use ash-blocking plate.

4.in order to reduce the number of wave sections of the bellows, should consider the cold pull 50%.

5. the compensator is suitable for the cross-sectional area of less than 4.6 square meters and the flue duct shape size has a side less than 1.5m but greater than 0.6mm. The standard full height corrugated compensator is suitable for all flue ducts.

Due to various constraints is quite complex, but any complex pipe system can choose a number of fixed bracket in different parts of the choice of different settings, it will be divided into a number of relatively simple shape of individual pipe sections, "Z" pipe sections and "pi" type pipe As there are many types of compensators, it is very important to select the correct type, therefore, in the overall design of the pipe system, the direction of the pipeline and the support system (including fixed pipe frame, guide sliding pipe frame, etc.) should be fully taken into account and the design and comprehensive consideration of the shape and configuration of the compensator, in order to show the best combination of safety, reasonableness, applicability and economy.

Rectangular metal bellows expansion joint it is a flexible element with bellows as the core, in the pipeline then for axial, lateral and angular compensation in three directions. Axial type compensator in order to reduce the self-excitation phenomenon of the medium. No internal casing in the product, to a large extent, limit the radial compensation capacity, so generally only used to absorb or compensate the axial displacement of the pipeline (if the pipe system really need a small amount of radial displacement, can be specified when ordering its diameter maximum displacement): transverse displacement compensator (large tie rod) mainly absorbs the transverse displacement perpendicular to the axis of the compensator, small tie rod transverse displacement compensator is suitable for absorbing transverse displacement, but also Can absorb the combination of axial, angular and any three directional displacements: hinge compensator (also called angular compensator). It is used with two on or three compensators (a single use of hinge compensator has no compensation capacity) to absorb transverse deformation in a one-way plane, universal hinge (angular) compensator, used by two or three matching, can absorb the deformation of three-dimensional direction.
