Unique Solution to Problem of ‘Spray-Out’ Leakages

ThermaFlue Spraysafe® Shield stops spray out and provides visual indication of a leak.

ThermaFlue Systems Ltd, the Doncaster based manufacturer of bespoke high temperature covers, has designed a uniquely effective solution to the problem of ‘spray-out’ leakages in high pressure flow control. The ThermaFlue Spraysafe® Shield prevents the dangerous affects of a ‘spray-out’ by interposing an impregnable barrier between the medium flowing through the pipeline system and the external environment. In the event of a leak, the escaping fluid is controlled within the shield, the pressure is dissipated, allowing the leaked fluid to gather and activate the visual or electronic indicator.

The innovative solution is believed to be the only product on the market that combines 100% joint coverage, high temperature resistance and a visual indication that a leak has occurred.

‘Peace of mind’

Applying ThermaFlue Spraysafe® Shields to an existing high pressure flow control system will prevent the often catastrophic consequences of a ‘spray-out’ leak. Indeed it was after hearing about a series of fires suffered by a large power generation company that the ThermaFlue team developed the Spraysafe Shields. The fires were caused by failing valve/pipe flange connections which sprayed pressurised lubrication oil onto the hot turbine exhaust manifolds.

‘Customers are finding that using ThermaFlue Spraysafe Shields provides them with the peace of mind that if a leakage occurs, the consequences do not go beyond those associated with the loss of that high-pressurised line’ said Sales Engineer Seb Price. ‘Serious incidents can be avoided for a relatively minor cost.’

The product is particularly successful on lines where flammable, corrosive or toxic liquids are being transported.

The Spraysafe® Shields, like the majority of ThermaFlue’s products, are made using flame resistant materials. The outer cloth meets BS476 Part 6 (Fire Propagation) & 7 (Class 1 rating awarded for surface spread of flame). Insulated shield use an insulation that meets BS476 Part 4 (Non-combustibility).

‘Bespoke design’

Shields can be manufactured to cover any and all types of valves and pipe connections. They can be fitted with insulation material to give a thermal barrier protection against internal or external temperatures of +230°C/- 10°C, which meets BS5422:2009. ThermaFlue’s inhouse design and manufacture departments mean that bespoke shields can be manufactured and delivered within 3-4 working days, though standard models which are held in stock can be delivered quicker. Thisincludes products to cover flanges, couplings, valves, unions, expansion joints, hose couplings, flowmeters, pumps, heat exchangers, pressure vessels, instruments, customised connections, tees and elbows.

ThermaFlue Systems Ltd has qualified engineering personnel, who can make site visits to advise customers on the best solution to specific problems. They also provide an on-site design and measuring service for any bespoke applications. ThermaFlue Spraysafe® Shields can be customised to special sizes and configurations.

‘Our engineering expertise and design department means we are fully flexible’ says Sales Representative Stephen Parsons ‘We can place the leak indicators in the best place, or even replace our visual orange ball indicator with an electronic indicator which alerts a warning system. The choice is really with the customer.’

Forthcoming Exhibitions

The ThermaFlue Sales team will be exhibiting the Spraysafe® Shields at two exhibitions at the NEC in the first half of 2014. Seb Price and Stephen Parsons will be delighted to discuss the benefits of the shields at ‘Maintec 2014’ in March and ‘Plant and Asset Management 2014’ in April. Indeed both Seb and Stephen are available for no obligation consultations using the contact details:
