Piping vibration is a major industry issue causing fatigue failures in process piping,
drain lines, ESD lines, and other connections. Wood Group’s pipe clamps are
designed to withstand vibration and extend the life of your asset.
Based on decades of troubleshooting vibration problems, Wood Group VDN
(formerly BETA Machinery Analysis) developed its own range of clamps for
vibratory service. These clamps have been used successfully in numerous
demanding compressor and pumping applications.
To prevent loosening, Wood Group’s clamps have longer bolts and sleeves,
increasing bolt stretch for a given preload by 3X over conventional clamps. Wood
Group provides certified Mill Test Reports (MTRs) and Quality Assurance (QA)
documentation on all metal materials, liners, and wear pads.

Description Pipe ≤ 6 in Pipe > 6 in
CL-1: Piping Vibration
Our most popular hold-down clamp for piping in vibratory services.
Design reduces vibration-induced loosening by increased bolt stretch;
a common industry-wide problem.
CL-4: Thermal Expansion and Vibration
Designed with vibration control in mind while allowing for thermal
growth; this slotted, gusseted clamp provides stiffness and flexibility.
CL-8: Insulated Pipe Clamp
Need hold-down clamps for insulated piping? The CL-8 is a versatile
design ideal for this application.
