CL Vibration Clamps for General Purposes

Field-proven designs for compressors, pumps and related piping systems

Pipe clamps for vibration loads must provide added stiffness compared to traditional U-bolt or flexible clamps.

Based on decades of experience, Wood Group VDN (BETA) has developed a range of vibration clamps for compressor and pump applications (included associated header piping).

CL-1: Piping Vibration
This is our most popular hold-down clamp for piping in vibratory services.

This design lessens vibration-induced loosening by addressing bolt stretch; a common industry-wide problem.   

Imperial: Model CL-1-xx
where xx refers to pipe diameter in inches: 1, 1.5, 2, 3, 4, 6, 8, 10, 12, 14, 16, 18, 20, 24, 30, 36, 40, 42
Metric: Model CL-1-xxM
where xx refers to pipe diameter in mm: 25, 40, 50, 80, 100, 150, 200, 250, 300, 350, 400. 450, 500, 600, 750, 900, 1000, 1050


CL-8: Insulated Pipe Clamp

Need hold-down clamps for insulated piping? 
The CL-8 is a versatile design ideal for this application.

Imperial: Model CL-8-xx
where xx refers to pipe diameter in inches: 1, 1.5, 2, 3, 4, 6, 8, 10, 12, 14, 16, 18, 20, 24, 30, 36, 40, 42
Metric: Model: CL-8-xxM
where xx refers to pipe diameter in mm: 25, 40, 50, 80, 100, 150, 200, 250, 300, 350, 400. 450, 500, 600, 750, 900, 1000, 1050

CL-1-T: Thermal Expansion and Vibration**

Designed with vibration control in mind while allowing for thermal growth; this PTFE-lined clamp provides vibration stiffness and thermal flexibility.

**Note: This new model is based on latest R&D results and replaces the CL-4.

CL-17 Vibration Clamp with liner Imperial: Model CL-1-T-xx
where xx refers to pipe diameter in inches: 1, 1.5, 2, 3, 4, 6, 8, 10, 12, 14, 16, 18, 20, 24, 30, 36, 40, 42
Metric: Model: CL-1-T-xxM
where xx refers to pipe diameter in mm: 25, 40, 50, 80, 100, 150, 200, 250, 300, 350, 400. 450, 500, 600, 750, 900, 1000, 1050
