Prevent Injury and Damage

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.

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 the shield to be reused. APS shields are UV stabilized and resistant to sun, rain, and fumes. They 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.

  • Cloth shields are available in five different materials and eight various styles.

  • Available for all standard 150# and 300# flanges.
