Inspection system for geometry of couplings

This system is designed to measure the parameters of couplings according to API, ISO 11960:2014 and special technical requirements for premium products.

  1. Outside diameter of coupling
  2. Length of coupling
  3. Inside diameter
  4. Wall thickness
  5. Chamfer
  6. Flank angles
  7. Thread height
  8. Lead
  9. Crest radiuses
  10. Gap radiuses
  11. Taper
  12. Crest thickness
  13. Standoff

Automated inspection system for thread geometry of oil and gas couplings is a portal coordinate measuring machine with a motorized rotary head. 2D laser scanner is installed on the motorized rotary head, which provides 5 degrees of freedom when moving relative to the coupling. The system has the following capabilities:

  • measurement of couplings with a diameter from 73 mm
  • measurement error of 5 microns
  • measurement performance from 1 coupling per minute
  • environment – laboratory or shop floor (depends on version)
  • integration with SCADA
  • operation log
  • results database management

Automated system for couplings thread geometry inspection expands the capabilities of buyers and suppliers of pipe products.
The buyer receives the following benefits:

1. A detailed quality inspection of all elements of API and premium threads, which will allow to identify and reject defective products.

2. Independence from the human factor, objective quality inspection of products through the rejection of manual contact inspection tools and the switching to modern smart devices.

3. Real time updating of the measurements database will produce an opportunity to automatically analyze the quality of suppliers and control the production process.

For its part, the supplier has the following advantages:

1. Timely detection of low quality production and improvement of one’s own reputation.

2. Refusal of manual quality control tools and save on their maintenance.

3. Automation and digitization of quality inspection, providing on-line feedback in real time, which will increase the percentage of quality production and reduce staff, thereby reducing the cost.

Our systems will become an integral part of Industry 4.0, as they will allow to combine the process of development, production and inspection into one self-regulating system, which will make the production fully automatic at all stages.
