The most inexpensive safety spray shields are economical and dependable. The Econo-Gard Safety Shields are expertly designed to achieve a safe yet economic protective guard. The price is lower than the other shields because it is fabricated using non-labor-intensive heat sealing methods.

Materials

Econo-Gard® Safety Shields are available in two thermoplastic materials:

• polyethylene (PE)
• polyvinyl chloride (PVC) (white, red and clear)

While the different Econo-Gard® Safety Shields have slightly different characteristics, both feature the same design and configurations.

Applications

Econo-Gard® Safety Shields have a more limited range of applications from the other safety shields. They are able to endure temperatures up to 140°F (60°C), lower in the presence of certain chemicals such as concentrated acids. They have wide applications particularly in conditions with ambient temperatures and pressures of 300 psi (21 bar) or lower.

These economical spray shields are useful in chemical processing industries which have less hazardous chemicals at low temperatures and pressures. They are also used in food processing and waste water treatment facilities. PE Shields are used in phosphate mining, and PVC Shields are used in seawater desalination plants.

Design

The FRP Safety Shields have a wrap-around design, for easy installation and reliable covering of flanges. They are designed with a three-ply lamination with an inner core of non-woven spun cloth interfaced between two sheets of either PE or PVC. This provides six layers of resistance against sprayouts. Four layers consist of PE or PVC film and are chemically resistant; the remaining two of non-woven spun cloth provide tensile and burst strength.

Features

The Econo-Gard® Safety Shields feature pH patches which signal leaks. There are several weep holes behind the patch which allow a slight flow of chemical to the indicator. Once the indicator comes into contact with the fluid, it changes color, alerting plant personnel to the presence of a leak.

Econo-Gard® Safety Shields can come in a clear PVC option. These are ideal for easy visual inspection. They have the same high quality characteristics of the other shields, but allow easy viewing of pipe joint – flanges, valves and threaded connections. Because these safety spray shields are see-through, an indicating pH patch is not needed.

Durability is a key issue when it comes to protective equipment. The Econo-Gard® Safety Shields withstood approximately 430 hours of UV testing. a period equivalent to 8 or 9 years of outdoor exposure. With this kind of rugged durability, both PE and PVC safety spray shields may be installed either indoors or outdoors.
