Specifications Data & Guidelines

Specification Data for Tube, Pipe & Hose Clamping

All tube, pipe and hose lines are to be secured using resilient Hydra-Zorb cushions with clamps and anchoring channel or other similar approved equal method.


Tube, pipe and hose are to be secured to the machine base or frame. Clamp assemblies shall allow:

 

  • pipe and tube sizes to be intermixed on variable centers to conserve space
  • for addition or removal of tube or pipe without unclamping other elements
  • tubes, pipes and hoses to be stacked back to back
  • installation without removing lines from supply or receiver

Cushions shall be of resilient material: resistant to oils, hydraulic fluids, grease, fuels, common solvents, dilute bases and mineral acids, and not degrade at operating temperatures of 275°F.
Entire clamp assembly can be assembled or disassembled with a single hand or power wrench. Clamps should be spaced not more than 60 diameters apart or a maximum of 5 ft.
Available in sizes from 1/4" to 6-1/8" o.d. tube and 1/4" to 6" nominal pipe. Available in mild steel, 304 and 316 stainless and aluminium (special order).
Classified by UL for use in air handling systems

Guidelines for Reducing Vibration Shock and Noise in Fluid Systems

Isolate Pumps

Use flexible coupling between pump and prime mover.
Use adequately-sized hose between pump pressure port and start of tubing runs. A two or three foot length is adequate.
Avoid solid contact between suction and return lines and fluid reservoir.
Isolation mounts between the pump and prime mover & the reservoir or machine frame are highly desirable.


Rigidly Mount all Valves

Mount all larger directional and flow control valves to the machine base or frame. Avoid in-line mounting.
Smaller two-port solenoid, in-line flow and in-line check valves can be considered rigidly-mounted when installed directly next to a clamp point.

Minimize Fluid Resistance

Use adequately-sized components and lines.
Avoid drilled junction blocks.
Keep conductor runs as straight as possible.
Use bends rather than right angle fittings. Straight fittings for disassemble and service may be used ass required.


Secure the Fluid Conductor System

Use resilient cushion clamps.
Normally, clamp spacing distance should not be more than 60 diameters.
Where severe vibration is present, clamp spacing distance should not be more than 30 diameters.
On long runs, vary clamp spacing by approximately 15% to break up and change vibration frequency.
Provide clamps as close as possible to each side of a bend.
Use unions rather than rigidly - mounted bulkhead fittings. Use clamps on each side of union to maintain alignment during service or re-installation.
All clamping should be made to the machine frame. However, clamping lines to each other is much better than not clamping.
Use adequate lengths of flexible hose where required. Clamp tube directly adjacent to hose connection point. Clamp hose to base or frame when practical.
