Seismic Shield

Description / Features

Seismic Shield ® is an innovative insulation protection shield offered by Value Engineered Products (VEP). This product is designed to stop shield movement and rotation while allowing for expansion and contraction of piping systems. Seismic Shield ® is designed to support the weight of the pipe and insulation. Each shield has Seismic Grip Tabs, which indicate a clear area to center the shield and may be bent down 90° to form a friction fit to strut or bent further to firmly grip a clevis hanger. Each shield has rounded corners for installer safety and vapor barrier protection.

Seismic Shield ® is offered in two grades Standard and MSS Compliant*

*Complies with MSS Type 40 – minimum requirements for small bore pipe


Seismic Shields ® in both Standard and MSS Compliant configurations are designed to be installed following the same guidelines as all VEP’s Insulation Protection Shields.
Specifications often allow shields without high density inserts on small-bore pipe. Steel shields alone may be permitted on larger diameter pipe, providing the length of the shield is sufficient to prevent the insulation from showing signs of compression from the weight of the pipe plus the weight of the media being transported along with any valves or fittings.
