DN65 PN6 flange pressure plate oil-filled directly buried sleeve compensator
Product Introduction
The sleeve compensator is called the tubular expansion joint, which is a compensation device for the thermal fluid pipeline, which is mainly used for the axial thermal expansion displacement absorption compensation after the auxiliary installation of the straight pipeline, and is a compensator directly installed in any pipeline that transports non-corrosive unidirectional or multidirectional fluid. It is widely used in the transmission pipelines of urban heating, metallurgy, mining, power generation, petrochemical, construction and other industries. It is mainly composed of sleeve (core tube), shell, sealing material and so on.
Product Advantages
1. The service life of the sleeve compensator is large, and the fatigue life is equivalent to that of the pipeline. The sliding surface is specially treated, and has good corrosion resistance in salt water, salt solution and other environments, which is more than 50 times higher than austenitic stainless steel. At the same time, when the sealing effect is weakened due to wear and tear after many years, the flange can be tightened again to enhance the sealing performance, or the bolt can be loosened, the pressure ring can be removed, and then one or two layers of sealing rings are installed, and the pressure ring can be pressed and continued to be used.
2. The sleeve compensator has no requirement for chloride ion content, especially suitable for systems with chloride ions exceeding the standard in the medium or surrounding environment.
3. The sleeve compensator is divided into one-way type and two-way type compensation structure, and the two-way type is characterized by the fact that no matter where the medium flows from the end of the compensator, the sliding sleeves at both ends of the compensator always slide freely to achieve two-way compensation and increase the amount of compensation.
4. The directly buried sleeve compensator can be directly buried underground, and the maintenance well can not be set up during installation, and the project cost is low.

How to install the product
1. The sleeve compensator should be properly kept during installation to prevent sun, rain and sand pollution.
2. During installation, check whether the model specification of the compensator is consistent with the design, and the surface of the product should be free of defects that affect product quality, such as bruises, pressure pits, and serious rust.
3. When the total length of the finished product of the disposable compensator is consistent with the sample, it is not necessary to stretch or compress it, and if the installation marking line on the telescopic main pipe changes, it should be adjusted before installation.
4. For the two-way non-thrust compensator, the medium flow direction noted in the diagram must be installed, and when the medium is steam, so as to avoid the formation of an air lock in the compensator. In order to ensure that the compensation amount in the two directions of the compensator is equal, the bidirectional compensator must be arranged in the middle of the two fixed points during the design.
5. The pipe section welded with both ends of the compensator must be broken, and the hydraulic test shall be carried out according to the requirements after welding (the bolts at both ends of the packing chamber should be tightened until there is no leakage during the pressure test). After 24 hours of operation, the bolts at both ends of the packing chamber must be tightened again.
6. In order to ensure that the pipeline has no lateral displacement, only the axial expansion and contraction is carried out, and the guide bracket is installed on the side of the telescopic pipe. When both parts of the compensator have axial displacement, guide brackets should be installed on both sides to ensure that the axial displacement does not exceed one degree of positive or negative (+-) eccentricity of the compensator.
7. The insulation and waterproof structure of the compensator can be the same as that of the pipeline, but it cannot be binding on the expansion section.
8. Special circumstances will be negotiated.
