Safe-Ring. The flange guard with diffuser and snap-lock

A spray protection ring for flange connections, which intelligently combines principles of fluid dynamics through its functional design. If a seal fails, an escaping fluid jet is effectively diminished through a special diffuser between the flanges and hazardous spraying is safely prevented. For heavy demands on plant safety.

Source of danger — flange connection.

Flanged joints on pipeline systems are an enormous source of danger and especially wherever they are used to transport poisonous, flammable or caustic liquids. In case of seal breakage, the result is a danger zone with a diameter of up to 40 metres. In order to reduce this zone to a minimum, flanged joints must be provided with a suitable form of spray protection.

Models

Performance at its best.

Conventional spray shields that are merely mounted around the outside of a flange only deflect escaping fluid jets in the direction of the pipe when a seal fails. In contrast, with its innovative diffuser technology, the Safe-Ring provides the type of protection expected from safety equipment in the event of an emergency. the escaping fluid simply flows off downward without spraying.

Functional design.

The diffuser of the Safe-Ring was designed as a c-shaped channel that clamps directly between the flange faces serving as an impact and deflecting surface. In the case of damage, the flow rate of an escaping fluid jet is safely slowed down through enlargement of the cross-section and massive turbulence in the intermediate space of the flanges. The snap-lock enables installation in a matter of seconds without tools.

Appropriate for the type. There are three types of Safe-Rings with respective diffuser widths suitable for the respective flange distance of various flange combinations.

Type SS

Diffuser width for steel flange connections comprised of two weld-neck flanges (as well as two loose-type flanges with flare).

Type SL

Diffuser width for steel flange connections comprised of a weld-neck flange and a loose-type flange with collar.

Type LL

Diffuser width for steel flange connections comprised of two loose-type flanges with collar.
