Industrial seismic absorber

 Industrial seismic absorber

Industrial seismic absorbers are part of connections that are used in systems to control and reduce vibration and noise caused by fluid movement as well as rotating equipment. these vibrations and tensions are sometimes so high that it is not possible to compensate for the damages and sometimes it leads to the destruction of the piping system. This has double the necessity of using a seismic absorber inn the industry. Seismic absorbers are used according to characteristics such as pressure and temperature tolerance and the connections in which they are used and have different types. Rubber, accordion, hose and metal seismic absorbers can be mentioned among the most widely used seismic absorbers in the market.

Product introduction

What is an industrial seismic absorber? Types of industrial seismic absorbers/technical specifications

Today, most industrial processes, tools called industrial seismic absorbers are used in order to control the oscillation of heavy parts and prevent sudden increase in temperature and pressure. For example, in refrigeration systems, the compressor is one of the devices that fluctuates a lot and produces a lot of noise. This can affect the movement of the fluid in the compressor building and cases pipeline breakage or fluid back flow. In such cases, industrial seismic can be used depending on the amount of vibration of the parts and the swing path of the parts. In the following article, information about thee types of models and features of these tools is provided for the information of our dear friends.

What is an industrial seismic absorber?

vibration absorbers are pert of the connections that are used in systems to control and reduce vibration and noise caused by fluid movement as well as rotating equipment. These vibrations and tensions are sometimes so high that it is not possible to compensate for the damages and sometimes it leads to the destruction of the pi0ping system. This has doubled the necessity of using a seismic absorber in the industry. Seismic absorbers are used according to characteristics such as pressure and temperature tolerance and the conditions in which they are used and have different types. Rubber, accordion, and metal seismic absorbers can be mentioned among the most widely used seismic absorbers in the market.                                                            Among the important features of these seismic absorbers, we should mention that the rubber seismic absorbers, we should mention that the rubber seismic absorber has the ability to control the system’s vibration and stresses in both vertical and horizontal directions and dose not allow it to be transmitted to other system equipment. This increases the lifespan of the system. Seismic absorbers are produced in 4 colors: blue, red, yellow and blue-red, each of these models has the ability to withstand different temperatures and pressures. The red type of seismic absorbers can withstand temperature up to90 degree and pressure up to 10bar they are suitable for installation in high temperature systems.

Type of industrial seismic absorbers

In general classification the seismic absorber available in the market are divided into two categories, metallic. Among them, the metal type is rubber and the non-metal type is accordion. Rubber seismic absorbers can be used in very corrosive environments, this has made it perform better than according seismic absorbers are more limited in pressure and temperature than accordion seismic absorbers. Can be used other used of rubber seismic absorbers include preventing electrical condition.

The working pressure of industrial vibration seismic absorbers in 10and 16 bar, and these seismic absorbers (based on the type of application) work at temperatures of 61 and 90 degree Celsius. The rubber seismic absorbers of Iran industrial vibration company are the type of restrained seismic absorbers with cast iron body, which are widely used in various industries.

Rubber seismic absorbers

The most important application of rubber seismic absorbers is to eliminate or reduce internal sudden seismic in pipelines, and they are also used to absorb vibrations and reduce pipeline noise. Also, rubber vibration can be used to absorb temperature vibration (expansion and contraction in the pipeline). Rubbers are often used in industries related to air conditioning, refrigeration and thermal processes, pipeline, water and sewage industry designs, power plants etc.

Accordion seismic absorbers

Accordion fittings can also be used as seismic absorbers in process systems. Depending on the type of design, these connections can reduce angular, axial and lateral vibrations in pipelines. Among the advantages of accordion anti-vibration is high temperatures and pressures.                                                                                                     Different blades and designs can be used in the design of accordion fittings. Flanges and bolts are often used to install these connections. the most important component in accordion anti-vibration design is its blues. This material of the blouse. Its degree of flexibility, thickness, shape of the blouse and the number of its blades can be changed and affect the efficiency of this piece. among the types of accordion fittings, we can mention single, double, hinged oscillating, etc.

Use cases of industrial seismic

• Oil and gas refineries
• Petrochemical industries
• Steel industries
• Cement industries
• Heat exchangers
• Wood and paper industries

Sizing of seismic absorbers

Seismic absorbers are usually produced insize1.25 inch to 10 inch and seismic absorbers larger than 10 inch are available with internal metal construction.

 The most important application of seismic absorber

According to experience, it can be said that the most use of seismic absorbers is related to the suction and sudden discharge stage of pumps, which in addition to absorbing the existing vibration, removes ram bellows and seismic on the pipeline. for example, if we see construction and expansion in a area due to the increase and decrease in temperature, without the presence of a seismic absorber, it will transfer a lot of pressure to the pipeline and can cause severe physical damage.

Classification of seismic absorbers according to temperature

• Red color: suitable for temperature of 90 degrees Celsius and pressure of 10 bar.
• Yellow car: suitable for temperature of 60 degrees Celsius and pressure of 10 bar.
• Blue color: suitable for temperature of 60 degrees Celsius and pressure of 16 bar.
• The blue-red color: suitable for a temperature of 90 degrees Celsius and a pressure of 16 bar.

Why is it necessary to use a seismic absorber?

The progress of science and technology industrial equipment has brought a safe and peaceful life to humans. In pipelines due to the connections between the pipelines due to the connections between the presence of equipment such as pumps, compressors, fans, etc. it creates internal movements between lines unintentionally.

This internal movements are the little and coarse vibrations. The vibrations resulting from these internal movements cause unbearable and annoying noise in various industries, including large engine houses and construction facilities.

In addition to creating abnormal sounds, these movements and vibrations may cause wear of connecting parts. This abrasion occurs due to multiple frictions and will be the reason for reducing the service life of the connecting parts.

These factors are one of the most important and necessary reasons to use seismic or anti-vibration parts related to any industry in the structure and design of pipelines. Also, the installation of seismic absorbers in various industries reduces the forces due to the contraction and expansion of pipe.

Conclusion

An industrial seismic absorber is a type of tool that reduces or completely stops the vibrations caused by increasing or decreasing the pressure of the material inside the pipes.

By reducing the amount of vibrations, industrial seismic absorbers reduce the damage caused by hitting other pipes and the pipes stay in their fixed position and do not get torn off.

Due to the widespread use of seismic absorbers, may types of this type of tool are produced for different environments. But generally, industrial seismic absorber are divided into two categories, metallic and non-metallic.
