Detailed introduction

管道补偿器

The pipe compensator is mainly used to compensate the heat expansion and cold contraction produced by the temperature change of the pipe. If the pipe is not completely free to expand or shrink when the temperature changes, the thermal stress will be produced in the pipe. This stress must be considered in the design of the pipeline, otherwise it may cause the rupture of the pipe and affect the normal production. As an important part of the pipeline engineering, the compensator plays an important role in ensuring the long term normal operation of the pipeline.

One. Brief introduction of pipeline compensator:

The pipe compensator is divided into metal ripple compensator, non-metallic Compensator, sleeve compensator, square compensator and so on. Metal ripple compensator and non-metallic Compensator are common in use.

1. The metal ripple compensator is composed of the bellows (an elastic element) and the accessories of the end pipe, the bracket, the flange and the catheter. It belongs to a compensation element. The effective expansion and deformation of bellows should be utilized to absorb the size changes caused by thermal expansion, shrinkage and other reasons, or to compensate for axial, lateral and angular displacement of pipelines, pipes and containers. It can also be used for noise reduction and vibration reduction. It is widely used in modern industry.

2, the non-metallic Compensator can compensate for the axial, lateral and angular displacement of pipelines. It has the characteristics of no thrust, simplified bearing design, corrosion resistance, high temperature resistance, noise reduction and vibration absorption, and is especially suitable for hot air pipes and dust pipes.

Two. The function of the pipe compensator:

1, to compensate for the axial, transverse and angular thermal deformation of the absorption pipe.

The deformation of the pipeline, 

    2, absorption of seismic subsidence.

3. The expansion of the ripple compensator is convenient for the installation and disassembly of the valve pipe.

4, absorbs the vibration of the equipment, reduces the influence of the equipment vibration to the pipe.

Three. The main form of the pipe compensator

There are three types of pipe compensators: axial, lateral and angular, and tens of thousands of types. The common methods are: single axial type; external axial type; buried type; directly buried type; single, double hinge type; single and double universal type; compound free type; straight pipe pressure balancing; rectangular corrugated compensator, and nonmetal compensator.

The compensator method has natural compensation and compensator compensation.

Natural compensation means to use the elasticity of the natural bend of the pipe itself to absorb the thermal deformation of the pipe. Pipeline elasticity refers to the ability of pipeline to produce elastic deformation under stress, change the geometry and restore the original shape after the stress disappears. It has been proved that when the angle of the pipe is greater than 30 degrees, it can be used as a natural compensation and the bend angle of the pipe is less than 30 degrees, and it can not be used as a natural compensation. The length of the pipeline natural compensation is 15 ~ 25m, the bending stress by BW should not exceed 80MPa.

The natural compensation can not be satisfied, and the compensator should be added to the pipeline to compensate the heat deformation of the pipe. A compensator is a component set on the pipe to absorb the heat expansion and contraction of the pipe and other displacement. The common compensators are square compensators, bellows compensators, sleeve compensators and spherical compensators.

Due to the use of heat pipe making steel and other metals, the thermal expansion and contraction change in its length is relatively large, so in the design and installation of heating pipe, should ensure that the pipeline can freely Rezhanglengsu, otherwise the pipeline will produce great thermal stress, resulting in the rupture of the pipe flange surface node and lax leakage and support hanger damage, so the pipeline thermal compensation for.

    Five. Principle of selection of pipeline compensator

Due to various constraints is quite complex, but any complex pipe system can use a plurality of fixed bracket to select different settings in different parts, divided into several separate pipe shape is relatively simple, "Z" type pipe and an n-shaped pipe section, and determined the deformation and the amount of compensation for each pipe segment, because a lot of compensator types, correct selection is very important, so in the design of piping system, should fully consider the direction of the pipeline and support system (including fixed tube frame, sliding tube frame) design and considering the shape and configuration of the compensator to achieve the best combination, safe, reasonable, applicable and economical.
