QB type spherical compensator

          
Product features:
QB type spherical compensator is also called spherical compensation joint. The product mainly depends on the angular displacement of the sphere to absorb or compensate the lateral displacement of the pipeline in one or more directions. The compensator should be used in pairs. A single spherical compensator has no compensation ability and can be used as a universal joint of the pipeline. The spherical compensator has the advantages of large compensation, no blind plate force and small force on the fixed pipe support. The sealing adopts injectable combined sealing technology to realize long-term reliable sealing.
Application:
Spherical compensator is a kind of equipment to solve the thermal expansion and cold contraction of pipeline, which can be widely used in metallurgy, petroleum, chemical industry, electric power, light industry, textile, construction and national defense construction, etc
1. It is used in thermal pipeline to compensate thermal expansion, and its compensation capacity is 5-10 times of that of "冂" compensator.
2. It is used in rocket launching pad and aircraft exhaust facilities to compensate shock expansion.
3. It is used as universal joint in vaporization cooling system of metallurgical equipment (such as blast furnace, converter, electric furnace, heating furnace, etc.).
4. It is used in various pipelines of buildings to prevent damage to pipelines due to uneven settlement of foundation or earthquake.
Selection and use of compensator
1. The reliability of compensator is composed of design, manufacture, installation and operation management. Reliability should also be considered from these aspects.
  2. In addition to the working medium, working temperature and external environment, the possibility of stress corrosion, the influence of water treatment agent and pipeline cleaning agent on the material should be considered in the material selection of corrugated pipe used for heat supply network. On this basis, the economical and practical bellows material is optimized by combining the welding, forming and performance price ratio of the material  
3. Generally, the material of bellows shall meet the following conditions:
(1) high elastic limit, tensile strength and fatigue strength to ensure normal operation of bellows.  
(2) it has good plasticity and is easy to be processed and formed, and enough hardness and strength can be obtained through subsequent treatment process (cold work hardening, heat treatment, etc.).  
(3) good corrosion resistance, meeting the requirements of bellows in different environments.  
(4) good welding performance, meet the welding process requirements of bellows in the manufacturing process.  
For the heat pipe network laid in the trench, when the pipeline where the compensator is located is at a low terrain, the corrugated pipe will be soaked by rainwater or accidental sewage. Therefore, materials with stronger corrosion resistance, such as iron nickel alloy and high nickel alloy, should be selected. Due to the high price of this kind of material, only a layer of corrosion-resistant alloy can be added to the surface contacting with corrosive medium when manufacturing bellows. The fatigue life design shows that the plane stability, circumferential stability and corrosion resistance of bellows are related to the displacement, i.e. fatigue life. Too low fatigue life will lead to the decline of stability and corrosion resistance of metal bellows.
