SAFETY SPRAY SHIELDS
Safety Spray Shields are used to prevent injury to personnel
or damage to equipment in the event of a leak or spray-out of
acids, caustics, chlorine and other dangerous liquids at
piping connections (such as flanges, valves, or expansion
joints) found in chemical, pulp/paper, petrochemical and
wastewater treatment plants. These Safety Shields are commonly
referred to as flange guards, flange covers, flange diapers or
flange protectors. Our Safety Spray Shields are constructed
from PTFE, polypropylene,
PVC, polyethylene and stainless steel and are used for preventing
spray-out of hazardous chemicals due to gasket or packing
failure on flanges, valves and expansion joints.
CLOTH
Our plastic cloth shields are manufactured from single
and multilayered clear cloth for easy visibility or a colored
cloth with a leak indicating patch. Weep holes located behind
the sensitive pH indicating patch allow the indicator to immediately
signal a leak and change color to red in the presence of an
acid or green if an alkali. The pH patch is also replaceable
which allows reuse of the shield. APS shields are UV stabilized
and resistant to sun, rain, and fumes and may be used indoors
or outdoors. Our cloth shields are quickly and easily installed
by one person without any tools by means of a Velcro fastener
and drawstrings which are standard.
