There are two kinds of structure of bellows compensator: the two ends of the flange connection are flange connections, and the middle is a stainless steel wave.

Welded connection, both ends are pipes, and the middle is a stainless steel wave.

There are many specifications, from DN20, DN25, DN32, DN40 all the way to DN3200 and even larger.

Function: shock absorption and noise reduction, protect the pipeline, and at the same time can compensate for the displacement of the pipeline in radial, angular, axial and other aspects, Gongyi Jiankun Water Supply Equipment Factory produces compensators all year round.

The implementation standard of corrugated compensator is GB T2000-2008.

The working principle of the bellows compensator is mainly to use its own elastic expansion function to compensate the axial, angular, lateral and combined displacement of the pipeline due to thermal deformation, mechanical deformation and various mechanical vibrations, and the compensation has the functions of pressure resistance, sealing, corrosion resistance, temperature resistance, impact resistance, vibration and noise reduction, which plays a role in reducing pipeline deformation and improving the service life of the pipeline. The main elastic element of the corrugated compensator is the stainless steel bellows, which relies on the expansion and bending of the bellows to compensate the pipeline in the axial, transverse and angular directions.

The role of the bellows compensator:

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

2.Absorb equipment vibration and reduce the impact of equipment vibration on pipelines.

3.Absorb the deformation of the pipeline by subsidence.

Here are some of the well-known brands recognized in the compensator industry that are widely recognized and have a great reputation. Although the ranking may change due to time and market conditions, the following brands are generally considered to be among the top brands in the valve industry: Water System Valves and Industrial ValvesThe following more influential first-line brands can be used as a reference, but are for reference only:

Suzhou Neway Valve, Shanghai Qizhong Valve, Shanghai Guanlong Valve, Sanhua, Su Yan, Shentong, Su Valve, Nanfang, Jiang.

First, the word Yao. The above manufacturers are only estimates and references, and the specific situation may vary or fluctuate at any time due to changes in a series of factors such as changes in the market, the size of the competition pattern, and the stability of product quality. As an indispensable key device in industrial production and civil facilities, the quality and reputation of the valve brand directly affect the satisfaction and trust of users.

These brands are known in the valve industry for their innovative technology, high-quality products and reliability. It is important to note that the market and industry are evolving rapidly, and different rankings may vary depending on time and region. For the most up-to-date ranking information, it is recommended to refer to industry reports, professional organizations or market research data for more detailed and accurate information.

1. Before installation, the compensator should check its model, erection specifications and pipeline configuration, and must meet the design requirements.

2. Attention should be paid to the direction of the inner sleeve to be consistent with the direction of medium flow, and the hinge rotation plane of the hinge compensator should be consistent with the displacement rotation plane.

3. For compensators that need to be "cold tightened", the auxiliary components used for pre-deformation should be removed after the pipeline is installed.

4. It is strictly forbidden to adjust the installation deviation of the pipeline by the method of deformation of the corrugated compensator, so as not to affect the normal function of the compensator, reduce the service life and increase the load of the piping, equipment and supporting components.

5. During the installation process, welding slag is not allowed to splash on the surface of the corrugated shell, and the corrugated shell is not allowed to be damaged by other machinery.

6. After the installation of the pipe system is completed, the auxiliary positioning components and fasteners used for installation and transportation on the corrugated compensator should be removed as soon as possible, and the limiting device should be adjusted to the specified position according to the design requirements, so that the pipe system has sufficient compensation capacity under environmental conditions.

7. All the movable elements of the compensator shall not be stuck by external components or limit their range of activity, and the normal operation of each movable part shall be ensured.

8. During the hydrostatic test, the sub-fixed pipe frame equipped with the end of the compensator pipeline should be strengthened so that the pipeline does not move or rotate. For the compensator and its connecting pipeline used for gas medium, it is necessary to pay attention to whether it is necessary to add a temporary bracket when filling with water. The 96 chloride ion content of the water cleaning solution in the hydrostatic test does not exceed 25ppm.

9. After the hydrostatic test, the water in the sedan car in the wave shell should be drained as soon as possible, and the inner surface of the wave shell should be dried quickly.

10. The insulation material in contact with the compensator bellows should not contain chlorine.

1. The corrugated compensator has an abbreviated model, and the name of the corrugated compensator model set by different manufacturers is also different. Normally, the product model is determined according to the relevant technical parameters of the corrugated compensator.

2. The meaning of the corrugated compensator model is very comprehensive, and we will take an example of the meaning contained in the model. Example: Means:

The working pressure is, WYS stands for unconstrained corrugated compensator, the diameter DN=300mm, 12 represents the wave number, F is the flange connection, and the product length is 500mm.

3. Due to the different names of the corrugated compensators set by each manufacturer, the meaning of the model is only somewhat similar, not the same.

It means that the nominal diameter is 500, the working pressure is, (6kg cm2) the wave number is 4, and the internal pressure corrugated compensator with deflector and carbon steel flange connection.

The working pressure is, the nominal diameter is 200mm, the wave number is 6 waves, and the directly buried corrugated compensator that takes over the connection.

The compensator is connected in series by one or more bellows, and there is an outer sleeve that can make the bellows move axially outside the bellows, which is a protective device and maintains its stability.

The corrugated compensator can not bear the load, it should be hoisted separately, unless the corrugated compensator is reinforced by measures, the corrugated compensator is not allowed to be hoisted together with the pipe after welding.

First, the corrugated compensator should be checked first when purchasing, and the key is that the pipeline configuration needs to meet the assembly design principles.

Second, the pipeline compensator with an inner coupling needs to pay attention to the same direction of the flow of the original pure wood, and the rotation plane design drawing of the pipeline compensator is the same as the offset rotation plane design drawing.

3. In order to be able to adjust the error caused by the installation of the pipeline, the corrugated compensator will be deformed, and the service life and ordinary function will be served, and it can also cause a burden on mechanical equipment, fulcrum prefabricated components and pipe fittings. If the cold tight pipe compensator is carried out, the pre-deformation often assists the prefabricated components to be removed after the pipeline construction is completed.

Fourth, the use of corrugated compensator ring to make a beam or knot, must avoid the corrugated shell being hit or harmed by industrial equipment, but also in the arc connection to avoid the welding area splashed on the surface of the corrugated casing, which affects the service life of the corrugated compensator.

Corrugated compensators are special pipe components. The installation process is complex and demanding. It is necessary to calculate the thrust of the pipe and the force of the fixing support.

Therefore, it cannot be installed without authorization, otherwise it will cause an accident. Therefore, the installation must have the detailed configuration of the pipeline construction drawings and pipe supports provided by the professional design department, and refer to the compensator installation instructions.

2.The pipes used to install the corrugated compensator must be properly guided and secured in order for the compensator to work properly. Therefore, the setting of the guidance and fixing brackets must be carried out in strict accordance with the relevant technical data of the design department.

3.The corrugated tube used for the corrugated compensator is formed from a thin-walled stainless steel plate. Therefore, during transportation, hoisting and welding, care should be taken not to cause damage to the bellows such as impact, scratches, arcs, welding spatter, etc.

4.Foreign objects in the bellows and pipes should be removed before installation to ensure the normal movement of the bellows.

5.Compensators with flow requirements should be installed in accordance with the requirements of the media flow arrows.

6.In order to keep the bellows in good working condition, the deformation of the compensator can not be used during the installation process, including axial, lateral, torsional, etc., to adjust the installation position error of the piping system.

7.It is generally not advisable to disassemble the small tie rod until the system is in operation. Instead, after the pressure is complete, loosen the inner nut according to the amount of compensation.

8.When purchasing, don't just rely on the model number or **, and provide data to the manufacturer, designed and produced by the manufacturer to ensure longevity or quality.

It is important to know that the length of the compensation pipeline and the temperature difference of the medium are multiplied.

The formula for calculating the expansion amount of expansion joints is: x=a*l*t

x Pipe expansion.

a is the coefficient of linear expansion, taken.

l The length of the compensation pipeline (the distance between the fixed supports of the required compensation pipeline) t is the temperature difference (medium temperature - ambient temperature during installation).

Specific calculations and installation precautions

Compensation amount = pipeline line expansion coefficient x pipeline temperature difference x pipeline length. For example, if the pipeline is a carbon steel pipeline, the temperature is 160 degrees, and one is installed at 60 meters, then the compensation amount is.
