Meter Proving

Meter Prover Spheres

Seamless, inflatable meter proving and pipeline spheres eliminate concerns over seam splitting or delaminating.

The unique manufacturing process permits valve bodies to be firmly embedded in the wall of the pipeline sphere to prevent leakage around the valve.  These spheres have a more consistent wall thickness, offering truer diameters resulting in more uniform wear and constant wall contact in meter-proving and measurement operations. The material provides greater flexibility for adapting to changing line conditions and better abrasion and blister resistance across a broad range of chemical and product environments.

  • One-piece construction
  • Inflatable sizes from 6” to 36” diameters
  • Solid spheres from 2” to 6” diameters
  • Truer diameters for meter-proving resulting in more accurate measurement

Meter Prover Spheres – Additional Information

In pipelines designed for running spheres, these are the ideal choice for hydrostatic line testing, two phase flow operations, product batching, separation or the control of hydrate and distillate formation in natural gas lines.  Magnet cartridges are available for use with Pig Detectors/Signallers.


Uses

  • Purge air and dewater during hydrostatic testing
  • Separate fluids
  • Liquid removal in gas lines
  • Pass through out-of-round pipe
