Non-standard corrugated pipe compensator has always had an irreplaceable position in the pipeline field. The key is the connection of the pipeline, which is very convenient for the disassembly and maintenance of the pipeline. Non-standard corrugated pipe compensator is divided into two types: flange corrugated pipe compensator and welded corrugated pipe compensator. Different types of corrugated pipe compensator are suitable for different use requirements in the pipeline field. Non-standard corrugated pipe compensator is an indispensable part in the pipeline field and has great use value in the pipeline field, what are the characteristics of the use of non-standard bellows compensator, take a look at it!
In the work, the corrugated deformation is used to complete the thermal compensation of the pipeline. The corrugated pipe used in the heating pipe network is mostly made of stainless steel.
Classification of corrugated pipe compensator: according to the classification of compensation type, it can be divided into axial type, horizontal and vertical type (compound tie rod), square type (hinge type) and other types. According to the shape of the corrugation, it can be divided into "u" shaped corrugation and "n" shaped corrugation.
The axial bellows compensator can absorb axial displacement and is divided into internal pressure type and external pressure type according to its pressure type. The vertical bellows compensator can deform in the axial direction of the compensator, and always adsorb the thermal elongation of the pipeline on the transverse longitudinal pipeline installed on the pipeline.
Non-standard bellows compensator uses the effective telescopic deformation of the bellows of the main body of the work to absorb the changes in external dimensions caused by the root causes such as thermal expansion, cooling and contraction of pipes, hoses, appliances, etc., or to compensate the radial, transverse and angular offsets of pipes, hoses, appliances, etc. It can also be used to reduce noise. There are many fields of application in industry now. In heating, in order to better avoid the temperature rise of the heating pipe network, a bellows compensator must be set up on the pipeline to compensate for the thermal elongation of the pipeline, reduce the wall thickness stress and effect on various valves and support frame structures. Interaction force, so as to avoid pipeline deformation and damage caused by thermal elongation and environmental temperature stress.
The specific content of the design idea and model selection of non-standard bellows compensator is to select the raw materials of bellows according to the known standards given by the system software, and to construct the basic parameters and technical parameters of the form factor and geometry. As a part of model selection, the application requirements of the system bellows should be fully met, and the effectiveness of the structure specialty should be guaranteed. It is best to complete the reliability design under the condition of standard. Practical experience has proved that the choice of design idea mode of bellows compensator is very important. If the choice of design idea mode is not scientific, the quality of bellows manufacturing will not reach the application requirements.
The above introduction is about the use characteristics of non-standard bellows compensators. Non-standard bellows compensators can bend and deform around the hinge axis. Like spherical compensators, a pair must be installed at the corners to complete thermal compensation of pipelines. Fatigue life refers to the number of cycles that a certain type of bellows compensator maintains without damage when the displacement range reaches the rated value under the specified nominal pressure level.
