Flange and valve covers as safety guards

Flange couplings in industrial plants are potential sources of danger against the safety of workers, especially in case of aggressive fluids and/or high temperatures, like acids, solvents, diathermic oils, steam.

The accidental breakage of the gasket in a flange coupling can generate an unexpected leakage at high kinetic energy, sprayed up to few tens of meters, causing workers injuries and equipment damages.

ARTEMA^® designs and manufactures safety shields from over 20 years to reduce harmful consequences of similar events: flange and valve safety shields, pressure gauge and level indicator covers.

Safety shields reduce spray effects, dissipating the pressure of the leakage and let the fluid dripping out of the safety shield, being a safety fence between the leakage and the external environmental.

Flanges and valves safety shields are manufactured in different materials, depending on the substance, temperature and pressure of the fluid they will be manufactured for:

• Stainless steel AISI 316 (suitable for ATEX areas)
• 100% PTFE
• Graphite filled PTFE (suitable for ATEX areas)
• PTFE coated fiberglass
• PVC

ARTEMA^®'s flange safety shields are available for all types of flanges (weld neck, blind, threaded, flat flanges, etc.) and for all sizes of flanges (UNI EN, ASME, JIS rules, etc.). Furthermore, ARTEMA^® can manufacture drawing flange safety shields (ex. spectacle/spectacle blind flanges, flanges with drip rings, orifice/orifice plate flanges).

ARTEMA^®'s valve safety shields are available for all types of valves, for example gate valves, butterfly valves, ball valves, diaphragm valves, etc.

For a better product functionality and a higher safety level in the plant, many accessories are available for ARTEMA^®'s flange and valve safety shields:

• leakage indicator with a replaceable litmus test, that varies the color in case of leakage
• leakage conveyor pipe (DRAIN)
• antitampering kit
• rigid pipe in stainless steel AISI 316 with borosilicate glass bottle to collect the leakage
• flexible pipe in stainless steel AISI 316 to convey the leakage from the safety shield to the place of collection
