With the growing awareness of the importance of safety at work and environmental protection, security guards are a natural consequence of the processes, hazardous or toxic. In fact the couplings flange piping systems represent a source of danger particularly high, especially for pipes used for the transport of chemicals, including toxic fluids, fuels, caustics, acids, solvents and alkaline solutions, or products whose temperature is extremely high or low, as heat transfer oils, liquid gas or steam. In the case of a rupture of a seal unpredictable, these hazardous fluids are sprayed from the coupling flange with a kinetic energy high and dispersed in a large radius around. The harmful consequences of an event of this type are reflected in costs for considerable damage to machinery and plant parts neighbors, but also in damage to the health and safety of the worker (your most valuable asset). Practical tests have shown that the danger area can reach a diameter from 30 to 40 meters, depending on the pressure and the position of the coupling flange. The anti-spray meet the standards set by regulatory agencies such as OSHA (European Agency for Safety at work) and are made ​​of PP (polypropylene) material durable and weather resistant to chemicals and UV.
