Testing and Inspection

Hydrostatic Pressure Testing, Leak Testing, NDT, Visual Inspection & Certification

We have been manufacturing High Pressure Vessels and Pressure Control Systems since 2004 and  we are [extremely] proud of the exemplary levels of quality and safety that exudes as a result of rigorous testing & inspection.

Our team of Testing & Inspection Engineers offer unlimited access to their services for customers with existing Pressure Vessels, Autoclaves and other types of Pressure Equipment that require the same levels of Testing and Inspection to ensure compliance with various Industry codes, standards or directives.

Post installation the implemented testing and inspection regimes of any piece of Pressure Equipment, Pressure Vessel or Pressure Control System is essential to the efficient running of any organisation.  In turn these regimes forms the basis of compliance to the Pressure Systems Safety Regulations 2000 (PSSR) and the customer in many cases is required to implement a Written Scheme of Examination to which KW Designed Solutions can provide assistance if required.

Hydrostatic Pressure Testing

Hydrostatic Pressure Testing can be carried out both in-house and on-site to provide assurances that the design strength, material quality and robustness of the sealing elements in any piece of pressure equipment are adequate enough to ensure longevity and reliability of manufacture.

Leak Testing

Often a gas will find a leak path where a liquid will not, so Leak Testing using a gaseous media can be carried out as a final confirmation that the Pressure Equipment is “leak tight” and ready for service or operation.  Leak Testing at Maximum Working Pressure can be carried out in-house and on-site depending upon the size and complexity of the equipment being tested.

NDT & Visual Inspection

KW Designed Solutions carry out 100% NDT and Visual inspections of all main pressure bearing components used in the manufacture of our Pressure Vessels.  However, there may be instances where an older Pressure Vessel or pieces of Pressure Equipment that is already in use, requires Non-Destructive Testing or Visually Inspecting to ensure that it can keep performing safely at the required operating pressure : -

Where significant corrosion is identified

When there are concerns about performance of “older” equipment

When damage has occurred or repairs and modifications have been carried out.

A dimensional and visual inspection can be carried out on areas of the equipment that are easily accessible, but techniques such as Magnetic Particle Inspection (MPI) & Dye Penetrant Inspection (DPI) can be carried out to identify surface and sub-surface damage and irregularities in the materials.

Ultrasonic NDT Testing can be used to measure wall thickness or identify internal flaws in the material or weld areas to determine whether the equipment can still perform as required.


All work carried out by KWDS engineers is provided with the necessary regulatory and legislative documentation to provide assurance and traceability for the customer: -

  • A fully comprehensive list of materials and parts used in the manufacturing of Pressure Vessels, Pressure Control Systems and other pieces of Pressure Equipment
  • Pressure Test Certification
  • Material certificates
  • Dimensional drawings & Inspection Reports
  • NDT Certification
  • Certificates & Declarations of Conformity
  • Notified Body Certification
