Valve Inspection

The Valve Inspection article provides you with information about the inspection of valves and valve testing in the manufacturing shop as well as in operational plants.

This article provides you lots of invaluable information about the following items:

Valve Inspection
  • Inspection and Testing During Manufacturing Phase
  • Inspection and Testing During Operation Phase
  • Industrial Valve Codes and Regulations
  • Maintenance and Repairs

This article, alongside other linked articles, are useful for Manufacturer's Quality Control Personnel, Second and Third Party Inspectors, Purchasers, Sellers, Plant Inspectors, HSE Engineers, Integrity Engineers, Operation and Maintenance Engineers, and any Other Interested Individuals.

Pressure Safety Valve Inspection - Are you looking for information about pressure safety valves inspections during the manufacturing process? Or you are looking for in-service inspection in an operating plant?

The pressure safety valve is a direct, spring-loaded pressure-relief valve that is opened by the static pressure upstream of the valve and is characterized by a rapid opening or pop action.

When the static inlet pressure reaches the set pressure, it will increase the pressure upstream of the disk and overcome the spring force on the disk.

Fluid will then enter the huddling chamber, providing additional opening force.

This will cause the disk to lift and provide full opening at minimal overpressure.

The closing pressure will be less than the set pressure and will be reached after the blowdown phase is completed.

This article covers both shop and in-service inspection of the pressure safety valve.

Third Party Inspection for Valve - This content guides you through all the necessary stages in the production of the valves, from the examination of certification of procurement sources to the final inspection, preservation and packing, to the dispatch to site.

It is particularly suitable for the inspection of Gate, Globe, Ball and Check valves. The following points are addressed in this article:

  • Valve Material Inspection
  • Valve Welding Inspection
  • Visual and Dimensional Checking
  • Valve Low Pressure Air Test
  • Valve Hydrostatic Testing
  • Post Hydrostatic Testing
  • Valve Final Inspection
  • Valve Name Plate Checking
