Introduction: Shanghai corrugated compensator, also known as expansion joint, or expansion joint. It is composed of bellows (an elastic element) and accessories such as end pipe, support frame, flange and conduit. The key is used in all kinds of pipes, which can compensate the thermal displacement of pipes

Shanghai ripple Compensator It is also called expansion joint, or expansion joint. It is composed of bellows (an elastic element) and accessories such as end pipe, support frame, flange and conduit. It can compensate the thermal displacement, mechanical deformation and absorb all kinds of mechanical vibration. It can reduce the deformation stress and improve the service life of the pipeline. Corrugated compensator The connection mode is divided into flange connection and welding. The directly buried pipeline compensator is generally welded (except for pipe trench installation)
Corrugated compensator is a kind of compensation equipment, which is used to absorb the specification change of pipelines, pipes or vessels caused by thermal expansion and cold contraction by using the reasonable expansion and deformation of elastic elements of the compensator. Absorption of axial, transverse and angular displacements
(1) divide the pipeline reasonably with fixed support to make it reliable and easy to compensate.
(2) during the installation of the line unit, the straightness of the pipeline should be ensured, and the fixed support must have sufficient rigidity and strength. In general, most of the damage of straight pipeline is caused by unreliable fixed support.
(3) for L-type, Z-type and Π type units, hinge type, large pull rod type and hinge type large pull rod type compensators must be used reasonably, and the harm of additional displacement should be considered.
(4) for the places that can not meet the load-bearing requirements of the fixed support, such as pipelines, steam turbines, condensers, fans and other places where the force of branch pipes is limited, the side structure type pressure equalizing type can be selected, that is, the three bellows pressure equalizing type of connecting pipe, the large pull rod type, the hinge type and other non pressure torsion compensators.
(5) the equipment with very small force is required to be able to undergo accurate measurement to make the pressure equalizing compensator cause unbalanced pressure torsion with opposite direction and adjustable size, so that it can counteract the elastic force and sliding friction force and complete the balanced pipeline. This is a new direction.
Generally, the unbalance of corrugated compensator usually appears and has been properly handled during the period of pipeline strength test after the installation of pipeline system.
Because of the different years of project implementation, we have different technical standards. We have laid the metal in the heating pipe network system software underground Bellows compensator The natural environment is different,
The nature of the design, the standard of the application, the standard of the design, the application and the application,
And according to different ways to create and change the method of integrating into the external natural environment, multi-faceted implementation. Generally, in the implementation of specific projects, some engineering projects can not be operated according to the law in the whole process of design scheme, engineering construction and management method, which results in some engineering projects cracking accidents of corrugated compensator in a short period of time.
