1 Anti-vibration wedge clamps

WCL-1 Anti-vibration wedge clamp

WCL-1 Anti-vibration wedge clamp

Applications:

• Hold-down clamps for piping in vibration service
• Variable height adjustment
• Easier inspections for piping corrosion
• Sizes from NPS 8” (DN 200) to NPS 42” (DN 1050)

Standard features:

• More bolt stretch than conventional pipe clamps, which reduces chance of vibration loosening
• Captive wedges and jigsaw shaped mounting plate remain under the pipe and will not slide off the support
• Customized finishes available: electroplated in nickel, zinc, or cadmium for sour gas, corrosive environments or offshore exposure
• Can be lined using PTFE to allow axial pipe movement due to thermal expansion
• Hardware and installation instructions included
• Carbon steel construction

WCL-1-T Anti-vibration ThermaGlide axial-slide wedge clamp

WCL-1-T Anti-vibration wedge clamp for low-friction applications (axial slide)

Applications:

• Hold-down clamps for piping in vibration with thermal growth requirements
• Where axial piping movement is required
• No metal-to-metal contact between pipe and clamp
• Easier piping corrosion inspections
• Variable height adjustment
• Sizes from NPS 8” (DN 200) to NPS 42” (DN 1050)

Standard features:

• More bolt stretch than conventional pipe clamps, which reduces chance of vibration loosening
• Low-friction PTFE lining clamp and wedge supports ensuring no metal-to-metal contact with pipe
• Allows axial pipe movement due to thermal expansion
• Captive wedges and jigsaw-shaped mounting plate remain under the pipe and will not slide off the support
• Customized finishes available: electroplated in nickel, zinc, or cadmium for sour gas, corrosive environments or offshore exposure
• Hardware and installation instructions included
• Carbon steel construction

WCL-1-T-ST ThermaGlide axial- and lateral-slide anti-vibration wedge clamp

WCL-1-T-ST Anti-vibration wedge clamp for low-friction applications (axial AND lateral slide)

Applications

• Hold-down clamps for piping with vibration and thermal-growth requirements
• Where axial and lateral piping movement is required
• Variable height adjustment
• Easier piping corrosion inspections
• Sizes from NPS 8” (DN 200) to NPS 42” (DN 1050)

Standard features:

• More bolt stretch than conventional pipe clamps, which reduces the chance of vibration loosening
• Low-friction PTFE lining clamp and wedge supports ensuring no metal-to-metal contact with the pipe
• Allows axial pipe movement due to thermal expansion
• Allows lateral pipe movement due to thermal expansion with patent-pending ST hardware and PTFE sliding plate provided
• Captive wedges, jigsaw-shaped mounting plate and sliding pad remain under the pipe and will not slide off the support
• Customized finishes available: hot-dip galvanizing, electroplating in nickel, zinc, or cadmium for sour gas, corrosive environments, or offshore exposure
• Hardware and installation instructions included
• Carbon steel construction

2 DamperX™ anti-vibration wedge clamps

WDCL-1-HT DamperX

WDCL-1-HT DamperX™ wedge clamp

Applications:

• Hold-down clamps with damping for superior resonant vibration control with DamperX™
• Variable height adjustment
• No metal-to-metal contact between pipe and clamp
• Easier inspections for piping corrosion
• Sizes from NPS 8” (DN 200) to NPS 42” (DN 1050)
• Temperatures from 15°F to 400°F (-9°C to 204°C)

Standard features:
