We completely understand the environmental and economic factors that drive the requirement for leak-free systems. In recent years, the successful management of bolted flange connections has been highlighted as a major factor in reducing leaks and fugitive emissions.

IntegrityXpert  - our industry-leading management system - has a comprehensive flange management module as well as sections on creating engineering work packs for integrity disciplines during Engineering, Construction, Commissioning, Plant start-up, Operations, and Maintenance scopes.

It allows KLINGER to incorporate all equipment, flange, and small-bore tubing breaks for ease of reference during the integrity verification process. It can also be used to plan work scope and produce work packs prior to the field execution stage.

IntegrityXpert is a bespoke system, developed to include all aspects of the joint assurance process. The flexibility allows client-specific developments, to their individual requirements and as the software has been developed across desktop, web, and handheld technologies it can be implemented in any environment.

Thanks to the single interface, clients can engineer, execute & control multiple construction, commissioning and maintenance activities including:

  • Flange Management
  • Hydro Testing
  • Blowing
  • Chemical Cleaning
  • Nitrogen/Helium Leak Testing
  • Small Bore Tubing
  • Valve Management
  • Machining
  • Pneumatic Testing
  • Flushing / Retro Jetting
  • Camera Inspection
  • Purging
  • PSV Management
  • Hose Management

At the core of IntegrityXpert is a comprehensive calculation tool that is compliant with ASME PCC-1 & EN-1591 standards. The software uses a component-based calculation to ensure that bolt, flange and gasket stresses are assessed under all applicable assembly, operating and test conditions.


The inclusion of proprietary gasket data allows KLINGER to provide a unique level of calculation with true gasket data at its core. IntegrityXpert can implement calculations for all standard piping systems as well as compact flanges, hubs, heat exchangers and non-standard applications.


IntegrityXpert has an inbuilt comprehensive PDF mark-up tool as part of the work pack creation. This allows P&IDs & isometric drawings to dynamically display progress of joint integrity work scope, through colour coding of the flanges in line with the client’s tagging procedure.


The overlay facility shows multiple services lines on a single drawing for full system overview, demonstrating system and subsystem progress and also acting as a control measure during testing activities.
