Steam Trap Integrity Surveys

Steam Trap Integrity Surveys – Energy loss reduction

Outputs / deliverables

  • Quantification of steam energy losses from most leak points found during a survey
  • Reduced energy losses
  • Improved process efficiency
  • P&ID’s marked up with steam trap ID numbers and cross referenced in all leaker reports
  • CIMS database updated with leak source details
  • Prioritised action lists for maintenance response actions


Service actions

Klinger can perform steam trap surveys on a stand-alone basis or as part of a wider component integrity management and energy efficiency program.


Klinger uses a combination of visual condition assessment criteria supported by ultrasonic leak detection technology on steam system components. Infrared thermography technology may also be used depending on client steam energy efficiency objectives.


Klinger applies a structured survey path methodology via a sequenced inspection route using component numbers and physical location descriptions.


The structured survey path methodology ensures that all steam traps are inspected. This is particularly important where a steam trap or block valve may be leaking steam to a common header and condensate drain point with no obvious localised visual leak.


Klinger brings extensive experience from conventional LDAR survey methodologies to steam trap surveys. This includes key survey elements like asset identification, data management and reporting systems.

Klinger steam trap surveys include seven key elements:

  1. Steam system component tagging and component specification data capture
  2. Mark-up of related steam system P&ID’s with survey ID tag numbers in order to reference leaks reported
  3. Component specification and location data entry into the Klinger component integrity management system CIMS
  4. Steam system energy loss field survey, energy loss point identification
  5. Component condition assessment and leak data capture
  6. Leak point emissions data conversion into energy loss estimations
  7. Energy loss estimation reports with suggested remedial actions per leak point


Klinger uses ultrasound technology for steam trap internal leak quantification using specific loss calculation algorithms based on OEM published steam trap flow rate coefficients, differential pressures, specific gravity values and saturated steam pressure and temperature tables. Algorithms used quantify steam losses are adjusted to reflect client specific energy loss trigger points beyond which remedial action may be justified.


Typical next actions

Post survey leaker review meeting to discuss survey results and schedule appropriate remedial action in response to steam traps identified to be performing poorly.

Clients may choose to incorporate the Klinger component Integrity Management System (CIMS) database as a tool to manage steam leak detection survey records. The CIMS database can use steam leak survey data to generate component repair requests and log remedial activities and schedule follow-up re-monitoring surveys.


Typical costing basis

Once off implementation, but may be included as part of an ongoing component integrity management system leak detection and remediation program.
