Flame Arresters

 

A Flame Arrester uses an element with small apertures which allows gas or vapour to pass. If the apertures are smaller than the maximum experimental safe gap (MESG) for the gas or vapour then a flame cannot pass through the arrester, and is subsequently contained or extinguished.

END OF LINE deflagration arresters with replaceable elements are designed to be installed at the end of a pipeline or exit vent from a vessel, where the ignition source is external, to provide protection against atmospheric deflagration.

End of line deflagration arresters are designed to be used in conjunction with pressure/vacuum relief valves, to prevent propagation of flames in gas or vapour mixtures. FE-IE arresters are specifically designed to be located below the inlet of a pressure/vacuum relief valve, thereby providing an extra layer of tank protection. FE-IE arresters are supplied as complete units ready for direct installation into piping systems.

Light duty end of line deflagration arresters with fixed elements are designed for installation at the end of a pipeline or on an atmospheric vent from vessels where flammable gases or vapours may be present.  SV arresters provide an economical solution for situations where a simple light weight product is required.  Typical applications include gas purging of equipment, sample lines and instrumentation lines.

IN-LINE deflagration arresters with replaceable elements in close proximity to the potential source of ignition, any flame or explosion is confined to the immediate area. DFB & DFC arresters are supplied as complete units ready for direct installation into piping systems.   In the context of the Pressure Equipment Directive (PED).

By locating the SGE-IB In-line Deflagration arrester in close proximity to the potential source of ignition, any flame or explosion is confined to the immediate area.  SGE-IB Def. arresters are supplied as complete units ready for direct installation into piping systems. In the context of the Pressure Equipment Directive (PED).

The Microbore in-line deflagration Arresters is specially designed for the protection of gas sampling and analysis equipment where flammable vapours are present. Many other applications involving small bore pipework can be protected from explosion risk using microbore arresters.

IN-LINE unstable detonation Arresters with replaceable elements are designed to prevent propagation of detonations in gas or vapour mixtures.

In-line unstable detonation arresters are specifically designed for pipelines with a significant distance between the ignition source and the arrester, or for use where the pipe is rough, bent, obstructed or has section changes.

Tank Furniture

 

EMERGENCY RELIEF MANHOLE COVERS

Emergency relief vents permit access to low pressure storage tanks and provide emergency venting in the event of fire. Non-sparking, low pressure access manways offer easy entry to low-pressure storage tanks for maintenance and cleaning.

» Size:  10”-24”
» Connections: API 650 (20" and 24"), ANSI 150#, Special
» Materials: Aluminium, Cast Iron, Carbon Steel, Stainless Steel
» Insert: PTFE
» Weights: Lead Plate (standard), Stainless Plate (special)

GAUGE HATCHES

Allow easy access to atmospheric liquid storage tanks for manual level measurement (dipping), temperature measurement and sampling. Gauges can also be combined with a pressure/vacuum relief mechanism, or free vent to offer various levels of pressure relief protection.

» Size:  4”-12”
» Connections: ANSI 150# (Standard), PN10/PN16, Special
» Materials: Aluminium, Cast Iron, Carbon Steel, Stainless Steel
» Insert: Nitrile, PTFE

PRESSURE TANK BLANKETING VALVES

Tank blanketing valves offer complete protection to the storage tank product against contamination and to the storage tank itself against rupture or damage. In addition to preventing outside air and moisture from entering the storage vessel, a blanket gas pressure reduces the evaporation of the stored product to a negligible amount.

» Nominal Bore: 15mm, 20mm, 50mm, 100mm

PRESSURE/VAC VALVES

Pressure / vacuum relief valves (also known as breather valves, conservation vents, or safety vents) are used extensively on bulk storage tanks, including fixed roof tanks with floating covers, to minimise evaporation loss. The valves prevent the build up of excessive pressure or vacuum which can unbalance the system or damage the storage vessel

» Nominal Bore: 2”, 3”, 4”, 6”, 8”, 10”, 12”

RIM VENTS

Free vents are designed for use on any atmospheric tank to prevent the build-up of internal pressure, by allowing atmospheres and vapours to flow freely in tanks or vent riser pipes.

» Size:  2”-12”
» Connections: ANSI 150# (Standard), PN10/PN16, Special
» Materials: Aluminium, Cast Iron, Carbon Steel, Stainless Steel
