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

We have manufactured high pressure vessels and pressure control systems since 2004 and are extremely proud of our exemplary levels of quality and safety; due to rigorous testing & inspection.

Our team of testing & inspection engineers are on-hand to provide unlimited access to customers with existing pressure vessels, autoclaves and other types of pressure equipment. These require the same levels of testing and inspection to ensure compliance with various industry codes, standards or directives.

The implemented testing and inspection regime of any piece of pressure equipment, pressure vessel or pressure control system, is essential to the efficient running of any organisation. These regimes form the basis of compliance to the pressure systems safety regulations 2000 PSSR. In many cases the customer is required to implement a written scheme of examination, which we can assist with if required.

Hydrostatic Pressure Testing

We can conduct hydrostatic pressure testing, both in-house and on-site, to provide assurance that the design strength, material quality and robustness of the sealing elements are adequate to ensure longevity and reliability.

Leak Testing

Leak testing using gaseous media can be conducted, as often gas will find a leak path where liquid wont.
This ensures the pressure equipment is leak tight, ready for service or operation and provides final confirmation.

Dependent upon the size and complexity of the equipment being tested; leak testing at maximum working pressure can be carried out in-house and on-site.

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.

Older pressure vessels or pieces of pressure equipment that are already in use, can also require non-destructive testing / visually inspecting to ensure they are performing safely at the required operating pressure.

This includes:

  • Where significant corrosion is identified
  • When there are concerns about performance of “older” equipment
  • When damage has occurred or repairs & modifications have been carried out

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

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


All work carried out by KWDS engineers is provided with the necessary regulatory & legislative documentation; providing assurance & traceability for the customer:

  • A Fully Comprehensive List of Materials & Parts Used Manufacturing
  • Certificates & Declarations of Conformity
  • Dimensional Drawings & Inspection Reports
  • Material Certificates
  • NDT Certification
  • Notified Body Certification
  • Pressure Test Certification
  • Pressure Vessels, Pressure Control Systems & Other Pieces Of Pressure Equipment
