    • Ensure the minimum surface contact meets the maximum allowable compressive stress of 60 N/mm² during hydro tests.
  • Opposite Plate Size: C=180/280 (dimension to be confirmed based on specific application requirements)
  • Holes for Screws: M8 holes must be precisely drilled to accommodate the assembly.

3. Assembly Instructions

Components Required

  • Sliding Plate
  • Opposite Plate (Stainless Steel)
  • Graphite Inserts
  • Screws and Nuts: Quantity based on the load and movement requirements
    • For vertical installations: Include head screws/nuts

Installation Steps

  1. Preparation:
    • Ensure all components are clean and free from debris.
    • Verify all dimensions and positions are accurate.
  2. Welding the Opposite Plate:
    • Weld the stainless steel opposite plate (5mm thick) to the primary support structure.
    • Ensure the welding process does not deform the plate.
  3. Drilling Holes:
    • Drill M8 holes in the opposite plate for screw installation.
    • Ensure holes are accurately positioned for minimal surface contact and maximum load distribution.
  4. Assembling the Sliding Plate:
    • Align the sliding plate (Cu82Ni4Al10Fe4 with graphite inserts) with the opposite plate.
    • Insert screws through the holes, ensuring the correct orientation of the graphite inserts based on the movement requirement (parallel or perpendicular to the pipe).
  5. Securing with Screws and Nuts:
    • For vertical installations, the sliding plate assembly should include head screws/nuts.
    • Tighten screws ensuring they are flush with the sliding plate surface.
    • Check that the screw length is appropriate: Sliding plate thickness + 20mm + 1.5 times the nut height.
  6. Final Check:
    • Verify that the assembly is secure and that the sliding plate is capable of moving as required.
    • Ensure that the minimum surface contact condition is met for the maximum allowable compressive stress during hydro tests.

4. Operational Considerations

  • Thermal Displacement: The sliding plate design must accommodate thermal expansion and contraction without compromising structural integrity.
  • Hydro Test: During hydro tests, the assembly must withstand the maximum allowable compressive stress of 60 N/mm².
  • Maintenance: Periodically check the assembly for wear and ensure that the graphite inserts are functioning properly to maintain self-lubrication.

By following these guidelines, you can ensure that the Cu82Ni4Al10Fe4 sliding bearing plate with a stainless steel opposite plate is installed correctly, providing reliable performance and longevity in your applications.
