The release of air, natural gases, nitrogen, oxygen or other process gases often generates high noise levels which can become dangerous to plant personnel and which may also be environmentally unacceptable. If this is the case at your plant, Flo-Dyne can help. After analysing what is required, we’ll design and build a vent silencer that is tailored to your needs, selecting the relevant pressure drop and flow velocities to ensure an effective, economical solution. Find out exactly how our atmospheric vent silencers are built by visiting the Flo-Dyne website.
Flo-Dyne’s highly popular diffuser silencer, known as the Hush Pup, is a non-packed reactive silencer that expands the incoming flow through a multitude of small holes in order to suppress noise. The correct selection of hole size, spacing and pattern allows this reduction in noise to be optimised, producing an overall quieting effect. It is a simple, yet remarkably effective principle that has been tried and tested in thousands of different applications. The Hush Pup is designed to be used in virtually any high pressure vent application where a moderate degree of silencing is needed. It offers a 15-20dB reduction in noise on most vent applications.
In-Line Silencers are designed to reduce high noise levels caused by gas compressors and ejectors - levels which can reach such peaks that they may, if left untreated, cause acoustic fatigue damage to downstream pipework. Each in-line silencer that we produce is custom designed using a highly specialised computer programme that enables us to match the silencer components, the packing, and the acoustic passage with the acoustic and flow characteristics of the system. Our ability to predict and meet noise levels ensures that our equipment fulfils its intended function of suppressing noise and thereby safeguarding plant pipework.
Surge control tanks are designed to inject a pre-determined amount of gas and liquid at the moment a surge event occurs. The required volume of air and water is usually calculated by a hydraulic analysis which examines the hydraulics for the whole pipe system. A sufficient amount is chosen to mitigate the transient pressures during a surge event. An incorrect volume of air or water could potentially lead to burst or collapsed pipes during a surge in pressure. This is avoided using a sophisticated control system that regulates the amount of air and water required. Find out more about our surge control tanks and the various control options available by visiting the Flo-Dyne website.
Flo-Dyne’s non-charged, maintenance-free liquid pulsation dampeners have been designed to reduce the damaging levels of pulsation and vibration often generated by multi-plunger high pressure reciprocating pumps. An innovative spherical in-line design keeps weight (and costs) to a minimum, and is ideal in situations where rubber bladder or metallic diaphragm types cannot be employed. Once fitted, the liquid pulsation dampener can be left to its own devices, since it requires no maintenance whatsoever. This is a tried, tested and proven design that has been used to ensure the smooth functioning of reciprocating pumps for over four decades.
Surge tanks are often used in conjunction with a compressor, or compressors, in order that additional air may be supplied into it if the liquid level rises above the normal conditions. This can be measured and detected using a simple level instrument that uses a magnetic float or a more advanced one that utilises radar or ultrasonic technology. In the event that the water reaches an undesirable level, either high or low, an integrated control system will automatically deploy the compressors, protecting the surge tank and connected plant.
In-line control valves and regulators often cause high levels of noise that may be radiated by the connecting pipework. In many cases, acoustic insulation and/or quieting valve trims are used to suppress this noise. However, both of these measures can be costly, not only to install, but to maintain, especially in the case of acoustic insulation. So we’ve come up with a better solution. Our engineers have designed an in-line silencer that is specifically designed to control the noised emitted by control valves and regulators, thereby preventing it from entering the downstream line to be radiated by the pipework. If you would like to find out more about how our control valve silencers work, please visit our website or get in touch with the team at Flo-Dyne directly.
Our diffuser silencers are designed to control high pressure drops across valves, reducing noise and preventing the deterioration of valve components. It does this by actually sharing the pressure drop with the valve. The diffuser is designed in such a way that it passes the flow through a series of small holes which are sized, spaced, and arranged to match the noise suppression requirements of each individual system. Correct hole size and spacing are critical for performance, we is why we design each diffuser for the exact valve and piping system it will be used with.
Compressors silencers and inline compressor silencers are very often specified for centrifugal and axial compressors which generate a broad spectrum of noise, with peaks at the blade passing frequencies. In addition, many piping systems are forced to endure low frequency noise both within the gas stream and along the pipewall. If this is not effectively controlled, the acoustic performance of the silencer may be compromised. Our customised Flo-Dyne compressor inline silencer has been designed to deal with these unique noise problems, giving you a highly efficient and effective silencing solution. Find out how it works by visiting the Flo-Dyne website.
The performance of reciprocating pumps can often be affected by pulsation problems on both the suction and discharge side. Many of these problems can be traced to poor suction conditions where the pressure of the pump’s inlet falls short of that required by the pump manufacturer. By fitting a Flo-Dyne Suction Stabiliser you can eliminate these problems, ensuring that the pump continues to perform as expected. Find out how it works by visiting the Flo-Dyne website.
Acoustic filters can be applied to multi-plunger hydraulic pumps, gear pumps and refrigeration compressors to eliminate the tones and pulses which can be harmful to connecting piping systems and which can create extremely districting sounds/vibrations. A multiple chamber design with connecting choke tubes aids acoustic attenuation, suppressing the dominant frequency and the most significant harmonics. Acoustic filters may be built for direct welding into the pipework or may be supplied with couplings or flanges to match the mating connection.
With no absorptive pack and a rugged construction, these silencers are able to handle the harmonic frequencies and high energy noise levels often generated by lobe type and multi-vane compressors. They are also extremely effective in reducing tonal radiation from the pipework which is connected to these machines. We use a sophisticated computer programme to analyse and predict the performance of each silencer application, allowing us to build a system which guarantees a solution to your noise control problems. Find out more about our Blower Silencers and all of the products listed above by visiting the Flo-Dyne website.
Our Exhaust Silencers are also designed to effectively control the harmonic frequencies and high energy noise levels generated by lobe type and multi-vane compressors. The multi-chamber design helps to significantly reduce tonal radiation from any pipework that is connected to these machines. Each silencer is carefully constructed with high-quality materials that are chosen to match the process gas and duty. All welding is performed by Flo-Dyne's experienced team of ASME IX qualified welders. For more information, please visit our website or contact us.
Our highly reliable Liquid Pulsation Dampener is a proven design which has kept pumps running smoothly for over 40 years. The dampener will typically reduce discharge pressure pulses by 75%. It is constructed with carbon steel as standard but other materials such as 304/316 stainless steel and duplex or super duplex steels are available for pressures ranging from 50 Bar G to 400 Bar G. Units can be manufactured to suit British, European, American and Indian pressure vessel codes and can also be CE marked to comply with European Pressure Equipment Directive requirements. Fluids which can be handled by our dampeners include water, ammonia, carbamate, hot oils, bitumens, CO2 and TEG.
Flo-Dyne's exceptional Gas Pulsation Dampeners can help to prevent mechanical failure of pipe materials caused by severe vibration. Our dampeners comprise either a single or multiple volume connected with tubes and/or orifices sized to attenuate the pressure pulses that can occur in a compressor's pipework. The highly sophisticated dampeners can be fitted to either the suction or discharge port of a compressor. For more information, please visit our website.
Our High Temperature Exhausts are an excellent alternative for environments where normal atmospheric silencers are unable to withstand extreme heat. Their clever structural design and cyclic life considerations enable them to easily handle temperature of up to 900 °C. They are typically designed to be inserted into the exhaust stack to sit on cross members within the stack. If you are looking high-quality silencers that are guaranteed to reduce noise and pressure drop, then Flo-Dyne can help.
