Ceramic lined compensator
Product Introduction: Ceramic lined compensator consists of a corrugated tube, two end tubes, and other ceramic components
Product details
Product Introduction
The ceramic compensator is composed of a corrugated tube, two end tubes, and other ceramic components. It absorbs axial displacement of the pipeline (with small amounts of lateral and angular displacement) through the flexible deformation of the corrugated pipe, and the end pipe is either directly welded to the pipeline or connected to the pipeline flange after welding. The small pull rod on the ceramic compensator is mainly used as a rigid support during transportation or as a pre deformation adjustment for the product, and it is not a load-bearing rod. This type of expansion joint has a simple structure and low price, so any possible location on the pipeline should be given priority consideration.
Product advantages
The working body of the ceramic compensator is composed of a corrugated pipe (an elastic element) and accessories such as ends, pipes, brackets, flanges, conduits, and ceramic plates. Axial inward pressure corrugated compensator belongs to a type of compensation component. By utilizing the effective expansion and contraction deformation of its working body bellows, it can absorb dimensional changes caused by thermal expansion and contraction in pipelines, conduits, containers, etc., or compensate for axial, lateral, and angular displacements of pipelines, conduits, containers, etc. It can also be used for noise reduction and vibration reduction. Widely used in modern industry.
Product Features
1. It has the function of wear resistance and high temperature resistance Compensate for axial, lateral, and angular thermal deformation of the absorption pipeline.
2. The expansion and contraction of the corrugated compensator facilitates the installation and disassembly of valve pipelines
3. Absorb equipment vibration and reduce the impact of equipment vibration on pipelines.
4. Absorb the deformation of pipelines caused by earthquakes and subsidence.
Bracket algorithm
Calculation of Bearing Force for Ceramic Compensator with Lining Internal Pressure Thrust: F=100 · P · A Axial Elasticity: Fx=Kx · (f · X)
Lateral elasticity: Fy=Ky · Y Bending moment: My=Fy · L
Bending moment: M θ=K θ ·θ Composite bending moment: M=My+M θ
In the formula: Kx: axial stiffness N/mm X: actual axial displacement mm
Ky: Lateral stiffness N/mm Y: Actual lateral displacement mm
K θ: angular stiffness N · m/degree θ: actual displacement measurement in the angular direction
P: Working pressure MPa A: effective area of corrugated pipe cm2 (check sample)
L: Distance m from the midpoint of the compensator to the support
Ceramic lined compensator:
A certain carbon steel pipeline with a nominal diameter of 500mm, a working pressure of 0.6MPa, a medium temperature of 300 ° C, and an ambient minimum temperature of -10 ° C. The installation temperature of the compensator is 20 ° C. According to the pipeline layout (as shown in the figure), an internal pressure corrugated compensator needs to be installed to compensate for axial displacement X=32mm, lateral displacement Y=2.8mm, and angular displacement θ=1.8 degrees. Given L=4m, the number of fatigue failures of the compensator is considered to be 15000 times, and the force on support A is calculated.
