Non-metallic compensator is a kind of equipment with very good performance and a wide range of applications, so it is often used in various fields. When using a non-metallic compensator, you must first understand its structure and composition, and choose the appropriate model to use it well. Then, let's take a look at the precautions for using non-metallic compensators.
This requires that the design of pipeline system should comprehensively consider the direction of pipeline, the arrangement of supporting system, the selection of compensator type, etc., in order to obtain a reliable, economical and reasonable scheme. In petrochemical, metallurgical, electric power and other industries, there are many high-temperature pipelines with medium temperature as high as 600} C, such as boiler waste heat pipeline in petrochemical industry, electric furnace steelmaking dust removal pipeline in metallurgical industry, circulating fluidized bed pipeline in electric power industry, etc. Therefore, there is an increasing demand for high temperature resistant non-metallic compensators. Temperature-resistant 600 high temperature non-metallic compensator (hereinafter referred to as XB} non-metallic compensator) is developed on the basis of research and production of various non-metallic compensators with operating temperatures below 400.
Non-metallic compensators are usually composed of metal structural parts, expansion joints, thermal insulation layers and other components. In the non-metallic compensator, because the medium temperature is as high as 600, in order to reduce the temperature at the connection between the flange and the expansion joint, a sleeve structure is adopted, so that the heat can be dissipated. Diffuse outward through vertical plates at both ends. In addition, when the compensator is axially stretched or compressed during operation, gaps are easily generated between the flanges of the heat insulation layer, and high-temperature channels are formed, which directly act on the expansion joint and affect the use of non-metallic compensators for non-seals. For this purpose, a double insulation design is adopted, i.e., insulation pillow and insulation layer. Heat insulation pillows are fixed on vertical plates at both ends of the compensator, and expansion joints are isolated from high-temperature media to increase the operating temperature of the non-metallic compensator. Ensure the normal operation of the workpiece.
What are the key points to pay attention to when using non-metallic compensators?
1: Non-metallic compensator is the core of compensator and pipeline, and the compensator has different compensation requirements for each medium pipeline.
2: The non-metallic compensator can be widely used in pipeline systems such as water supply and drainage, circulating water, HVAC, fire fighting, paper making, pharmaceutical, petrochemical, ship, water pump, compressor, fan, etc.
3: Excellent etching and sealing performance. Simple installation, can meet the axial compensation of pipeline, and large compensation amount is the advantage of axial compensator.
Non-metallic compensators can be widely used in pipeline systems such as water supply and drainage, circulating water, HVAC, fire fighting, paper making, pharmaceutical, petrochemical, marine, water pump, compressor, fan, etc. The common type is used to transport-15~115 air, compressed air, water, seawater, oil, acid, alkali, etc. The mold is used to convey the above medium or oil, concentrated acid and alkali, solids above-30~250. Non-metallic flexible compensators consist of flexible compensators, flanges or pipes, materials and bolted rods, etc., which provide large axial, angular and lateral displacements in small sizes.
Non-metallic compensator features no reverse thrust, the main material is glass fiber fabric and its coating products, no power transmission. The use of a non-metallic compensator simplifies the design, avoiding the use of large brackets and saving a lot of material and manpower. And noise reduction and shock absorption (fiber fabric and thermal insulation cotton themselves have the function of sound absorption and shock absorption, which can reduce the noise and vibration of boilers, fans and other systems). It is mainly used for displacement compensation caused by temperature change, mechanical vibration and foundation settlement in dust, gas, flue gas, gas and other gas conveying pipeline system, and has the performance characteristics of non-metallic compensator; It is mainly composed of flexible compensation material (non-metallic material), connection material at both ends (flange or end tube), adjustment material (threaded rod) and material.
