Seismic-Rated Piping Protection That Keeps Buildings Online
V-Loops, expansion joints, and flexible connectors engineered to absorb seismic movement without pipe failure
Why Seismic Protection Matters
Seismic Movement
Building piping must absorb multi-directional movement during seismic events. Rigid connections fail first, causing flooding, gas leaks, and system shutdowns.
Code Compliance
IBC, ASCE 7, and local codes require flexible connections at building joints and risers. Non-compliant installations risk failed inspections and liability exposure.
EFP Protection
V-Loops and U-Loops, OSHPD-certified products rated for seismic zones 1 through 4 — proven to protect critical building piping infrastructure.
Seismic Piping Products
Seismic V-Loops
Multi-directional movement absorption. The industry standard for seismic piping protection at building separation joints.
U-Loops
Available in flanged, threaded, grooved, beveled, and press end configurations. Versatile seismic protection for any piping system.
Rubber Expansion Joints
301/302 series for building HVAC systems. Absorbs thermal and seismic movement in chilled water and heating piping.
Metal Expansion Joints
High-cycle bellows design for critical applications. Stainless steel construction for long service life under repeated movement.
Pipe Guides and Anchors
Controlled movement systems that direct piping forces into expansion joints. Essential for proper seismic system performance.
CSA-Rated Products
Canadian seismic certified products for cross-border projects. Meets CSA requirements for seismic bracing and flexible connections.
