Rotary flange expansion joints are vital parts for pipelines. These compensators, which provide flexibility in the pipeline and enable comfortable movement, can also be used for different purposes. One of the reasons why it is widely used is that it can eliminate the negativities such as expansion and contraction that occur in hot or cold pipelines. Problems that develop due to heating or cooling in pipelines with cold or hot liquid flow can reach very serious dimensions. The use of rotary flange compensators in these pipelines will ensure that the pipeline has independent parts. Thus, the parts that move independently are minimally affected by the negative effects of heating or cooling. Rotating flanged expansion joints are also suitable to be produced in different diameters upon request. Therefore, it is possible to benefit from rotary flange expansion joints for pipes of almost any size.
Rotating flanged expansion joints, in addition to their flexibility, also have an anti-vibration feature in pipelines. It can also be preferred as a solution against vibrations occurring in pipelines and deformations due to these vibrations. The standard material of the rotating flange expansion joints, which are also suitable for easy use in terms of assembly, is carbon steel.
However, it is also possible to manufacture rotating flanged compensators from stainless steel or other material, depending on the area of use or personal demands. Different materials can be preferred depending on the nature of the pipeline or the situations needed in the line. This also applies to the diameters of rotary flange expansion joints. Again, it is possible to produce the material in different diameters in line with the demands.
Rotating flange expansion joints are a product that prevents pipelines from being affected by the negative effects of cold or hot liquid flow by gaining flexibility. The rotating flanged compensator, which is easily mounted, ensures that the pipeline problems caused by shrinkage and expansion are completely eliminated.
In some cases, especially in external pipeline installations, very serious deformations may occur in pipelines due to the temperature of the liquid flowing through the installation or external factors. While these deformations affect a whole line, in some cases, they may have a regional effect. The rotating flanged compensator ensures that the pipeline continues to function in a healthy way, regardless of the effect of temperature. Thus, deformations caused by external factors can be prevented.
Rotary flange expansion joints basically have three different functions. In pipelines where hot liquid flow is intense, serious expansion problem may be encountered. The expansion problem not only directly affects all the features of the installation, but also has an effect on the liquid pressure. The first function of the rotating flange expansion joints is to prevent this expansion.
Another function of this type of compensator is to prevent shrinkage in the pipeline caused by cold liquid flow. Rotating flanged expansion joints prevent shrinkage and ensure that the pipeline continues to function without loss of pressure. Another function of rotating flange expansion joints is to prevent vibration in the pipeline. High pressures in some pipelines can cause deformation in the line or in the pipe system.
Rotary flange expansion joints are suitable for use in all pipelines where problems such as expansion, contraction and vibration are experienced. The fact that it can be produced from different materials has enabled it to have a wide range of uses. At the same time, the rotating flanged compensator can be produced in different diameters, making it suitable for every pipe installation.
