Vulcathene Thermal Stress Relief Unit

Vulcathene Thermal Stress Relief Units (SRUs) are crucial components in laboratory drainage systems, designed to accommodate thermal expansion and contraction in pipework. These units ensure the integrity and longevity of chemical waste drainage systems by preventing stress and potential damage caused by temperature variations.

• Versatile Installation: Can be installed either vertically or horizontally to suit various plumbing layouts.
• Integrated Fixing Clip/Collar: Ensures correct directional installation, with a moulded fixing clip or collar indicating the outflow end.
• Mechanical Pipe Couplers: The V5452201 model comes equipped with 51mm mechanical pipe couplers at each end for easy connection.
• Secure Anchoring: Units must be anchored with a metal clamp for stability, allowing free movement of pipes to accommodate expansion and contraction.
  O-Ring Seal: Incorporates an O-ring seal within the body for enhanced sealing capabilities.

Creating a secure mechanical joint with Vulcathene fittings involves a precise and methodical process to ensure optimal joint integrity and system performance. Follow these steps for installation:

1. Cutting the Pipe:
   • Use a rotary plastic pipe cutter for a clean, burr-free cut. Clamp the pipe to avoid distortion.
   • Ensure the cut is square. If a hacksaw is used, remove all burrs and loose material.
   • Groove the pipe using the appropriate grooving tool for the tongued olive to fit in.
2. Grooving:
   
   • Insert the pipe fully into the grooving tool.
   • Adjust the blade depth to about half and rotate the tool anti-clockwise around the pipe.
   • Increase the blade to full depth, continue rotating, then remove the tool and clear any swarf.
3. Assembling the Joint:
   
   • Slide the nut onto the pipe, with the threaded side facing the groove.
   • Insert the olive (widest end first) into the groove. Use Vulcathene lubricant for ease, especially with larger sizes.
   • Ensure the olive is correctly seated and the fitting thread is clean. Apply lubricant to the fitting threads.
   • Loosely assemble the joint and hand-tighten the nut using two Vulcathene spanners, then tighten fully to ensure a secure fit.

Note:

• Tighten nuts progressively during installation, not all at once at the end.
• Use the Vulcathene grooving tool and spanners to guarantee the joint's integrity.
