What is the Role Of Flex Connectors In Noise And Vibration Dampening?

Today’s industrial world requires noise and vibration control considerations for safe and effective operations in many fields. Loud sound and vibrations can reduce equipment performance/equipment lifetimes and create work environment hazards. Solutions include using suitable flex connectors.

To alleviate this situation flex connectors are longitudinal stiffened hoses or pipes insulated from noise transmission that absorb the vibrations in piping systems. These versatile parts prevent excessive noise and vibration which from any source is the enemy of any machine over a long period. This paper will describe the two types of flex connectors, their operation and results in industrial settings.

Flex connectors may have different materials or formats to match your application or environmental conditions. These are essentially all kinds of flex connectors:

Rubber Flex Connectors: They are rubber flex connectors covered with cloth. Suitable for most modest temperature and pressure conditions. Vibration isolating and noise reduction performance of rubber flex connectors are good for HVAC systems, water supply tubes of all kinds and pipe to bedrock huge industrial application.

Metal Flex Connectors: Metal flex connectors can be stainless steel, bronze or alloys. Their construction is rated for very high temperatures, pressures and sometimes very corrosive surroundings. These metal flex connectors are usually found in industrial piping system, exhaust line and process control equipment, and provide good resistance to extreme conditions and good performance in noise level vibration programs.

Chemically resistant PTFE flex connectors are an example of such “flexible” material. They keep their purity and non-stick properties while being tolerant of most solvents and chemicals used in pharmaceutical, food processing and chemical industries. PTFE flex connectors also exhibit low noise and low vibration dampening properties.

To choose the right flex connector depends on application / operating condition and noise / vibration control requirements.

Flex connectors damp noise and vibration in piping systems in several ways.

Damping Vibrations: Flexible materials called flex connectors take up and dissipate vibrations from equipment like pumps, compressors and engines. Using flex connectors as a buffer between vibration source and piping system, damage vibrations are not propagated within the system. Reductions in vibrations reduce stress on pipes, fittings and other components-this extends their life and reduces maintenance requirements.

Isolating Sound Transmission: Apart from vibration dampening function, flex connectors are also used to isolate noise transmission through pipeline system. The direction change capability of these connectors can cut off waves from traveling along pipes. Flex connectors reduce the noise transmission for a quieter and more pleasant working environment which is appreciated in fields such as healthcare, schools and office buildings where noise levels are controlled.

Loud work can cause health problems. Noise levels are among the most space-consuming contributors to a list of health & safety hazards in any modern factory. These have an impact on the central nervous system as well as being an apsychological burden on staff members. People become deafer when they can no longer hear orders and less productive work occurs. Noise pollution from a pipe system is one of the hazards in a factory. Flex connectors eliminate sound transfer to work places. Less noise means better hearing for employees and more communication possibilities – all this contributes to workplace health and safety compliance.

In addition to these main advantages flex connectors provide advantages such as easy installation, flexibility in piping configurations, compatibility with many media and operating conditions.

Since personal safety is so important in pipework systems they are expected to have noise and vibration reduction as one of their functions. Consequently, some factors should be taken into account when selecting flex connectors for noise and vibration dampening. Besides, we have some suggestions that we hope will make your noise and vibration engineering projects run smoothly.

Material Selection: And so the material of a flex connector will depend on its usage as well as the environment in which it will operate. Temperature range, pressure rating, chemical compatibility and flexibility requirements are commercial considerations when choosing the right flex connector material. Rubber flex connectors accept moderate temperatures and pressures. Metal flexible coupling is suitable for high temperature and corrosion environments. PTFE flex connections are chemical resistant and suitable for high purity.

Size and Configuration: The flex connectors have to be sized properly for noise and vibration damping purpose. Pipe diameter and bend length should be selected depending on pipe size, flow rate and movement required in the system. Sized undersized bends will not be flexible enough and large ones will move too much the system. Any system variation or flow element that it has should also be considered and expert advice should be sought when required for any special problem that arises.

Your flex connectors must go in properly. In this way you ensure they work best and last longest.

Consider these factors and follow installation best practices when choosing the appropriate flex connectors for your application. They can also guarantee effective noise and vibration damping of their plumbing systems.

In addition, noise and vibration are workplace trends that no industry can ignore. Those goals will require flex connectors that will endure decades.
