Flo-Dyne - Industrial Silencing and Noise Control

Flo-Dyne design and supply customised solutions for industrial silencing and noise control. Their products include:

• Vent silencers for steam and gas duties
• Suction and discharge pulsation dampeners for reciprocating power pumps and compressors
• Diffuser silencers for control and pressure regulating valves
• Surge arrestors and tanks for water and waste water pumping stations

Flo-Dyne solutions will attenuate the noise, vibrations and pulsations generated by the movement of gases and liquids caused by changes in pressure.

VENT SILENCERS

The release of high-pressure air, steam and gas to the atmosphere generates noise that is dangerous to plant personnel and is environmentally unacceptable.

Flo-Dyne technology provides the most economical solution with optimised silencer design and guaranteed performance. Flexible design practice allows easy customisation for each individual solution combining advanced technology, suitable materials and best practice in construction techniques. Standard design solutions are available for relief valves, steam vents, process gas vents and steam ejector duties.

CONTROL VALVE SILENCERS

Control valve silencers are built to withstand the high pressure and high noise level environment downstream of pressure control valves. When control valve silencers are used in conjunction with standard trim valves they provide the most cost-effective means of valve silencing.

Using Flo-Dyne's pressure vessel construction experience and applying the acoustic technology from the vent silencer range, this solution often avoids the need for costly quiet trim valves.

COMPRESSOR INLINE SILENCERS

The compressor inline silencer is built to treat these special noise problems and will reduce the noise radiated by the suction and discharge pipe work, reducing the need for expensive acoustic lagging systems.

Inside the silencer the acoustic packing is protected by glass fibre cloth and stainless steel mesh to prevent loss of fibre into the gas stream and is arranged for low-pressure drop to minimise power losses.

LIQUID PULSATION DAMPENERS

Multi-plunger high-pressure reciprocating plunger power pumps produce damaging levels of pulsation and vibration. Reduction of these detrimental forces can be achieved by fitting the Flo-Dyne liquid filled pulsation dampener. The spherical design offers a low weight and low cost solution, which is maintenance-free with a low cost of ownership.

The liquid pulsation dampeners are manufactured to all European and American pressure vessel codes. The liquid pulsation dampeners can be CE marked and produced in a variety of carbon duplex or super duplex stainless steels.

SURGE ARRESTORS

Flo-Dyne's service includes surge analysis, field survey and measurement to the design, supply, installation and commissioning of hydro-pneumatic surge vessels.

Surge arrestors are used for pumped potable, raw water and sewage mains with automated controls and high quality ancillaries. Accumulators and bladder type surge vessels are offered in a standard range with a variety of bladder materials to enable use with fluids.

PUMP SUCTION STABILISERS

Insufficient positive inlet pressure, or NPSHA at the inlet of a multi-plunger reciprocating power pump will result in an excessively high acceleration head. This leads to a damaging cavitation within the pump. Installing a Flo-Dyne pump suction stabiliser at the inlet to the pump will eliminate this excessive acceleration head.

Entrained gases in the liquid column are encouraged to separate by the internal design so that the most complete liquid charge possible is provided to the pump.

GAS PULSATION DAMPENING

Reciprocating gas compressors can generate high levels of pulsation in the suction, interstage and discharge lines, which can lead to excessive vibration levels and pipe failure. Flo-Dyne gas pulsation dampeners will eliminate these harmful pulsations with minimal pressure loss and power consumption.

Robust design combined with pressure vessel construction provides the most economical solution possible.

FLO-DYNE

Flo-Dyne manufacture to British, European and American pressure vessel codes and standards with full quality control to ISO9001; CE marking will be applied when required. Uncoded equipment is manufactured in the UK to high standards and all products can be made in a wide range of materials from ordinary carbon steels through to duplex and super duplex stainless steels.

Used extensively throughout the world by gas, water, power, chemical and process industries, our equipment provides cost-effective solutions that deliver guaranteed results.

All product lines are designed using sophisticated computer programmes enabling Flo-Dyne to design suitable equipment for every customer.
