Calculation of bellows axial expansion joint
general characteristics
Compensators for heating systems extinguish the axial displacements of the elements of the pipeline system, which can be provoked by pressure drops in the risers of multi-storey buildings. Used for effective protection against deformation.
Device Features
All elements are made of high-quality corrosion-resistant steel. Thanks to such a durable material, the inner glass does not allow to lower the pressure in the system, the stroke limiter keeps the compensator working at the level of required performance, and the protective casing reliably protects the outer part from any damage.
The design is equipped with a rather flexible bellows, which compensates for axial changes. High strength of the product is provided by the presence of a protective casing and guiding rods. Due to the casing, the compensator is protected from the pressure exerted by the weight of the pipeline in case of damage or sagging.
The bellows is protected from damage by a special internal spigot, whose task is also to protect the corrugation from settling and accumulation of dirt. The presence of a special mechanism prevents the occurrence of unforeseen loads exerted on the bellows.
Installation
As a rule, expansion joints of heating systems are supplied in a stressed state. When the device is inserted into the pipeline system, it starts to function automatically in the prescribed rhythm. This mechanism is designed in such a way that it can not damage the compensator’s operation in the event of accidental rupture, in addition, it optimally corrects the movement of the compensating device throughout its life.
Main advantages
— Ease of installation;
— aesthetic appearance, thanks to which devices can be used in modern buildings, hotels and houses;
— equipped with a limiter, allowing you to track the maximum and minimum boundaries and pre-tension;
— prevents the appearance of noise and deformation resulting from thermal pressure.
Application
Expansion of the pipeline with a water supply temperature of 70−90 ° C is approximately one millimeter per meter of the pipeline system. Until the appearance of expansion joints, air outlets and pipe bends were used to neutralize the thermal pressure. To carry out these works it was necessary to spend a considerable amount of money. In addition, the pipeline was quite unattractive, unaesthetic. The appearance of the compensator changed a lot for the better. At 30 meters of the pipeline requires only one compensator for heating systems. The total compensating power of these devices reaches 50 mm. For installation, a straight pipe section must be chosen between two completely immobile supports.
