Valve, Steam Trap & Filter Inspections
PSSR examinations for safety valves, pressure relief valves, steam traps, strainers and in-line filters.
LDN Inspection Services provides statutory PSSR examinations for safety valves, pressure relief devices, steam traps and filtration equipment. Our qualified pressure systems engineers examine all types of protective devices and ancillary components, delivering clear digital reports with photographic evidence.
Valve & Steam Trap PSSR Examinations
Safety valves, pressure relief valves and steam traps are critical protective devices within pressure systems. Under the Pressure Systems Safety Regulations 2000 (PSSR), these components must be included in the written scheme of examination and examined by a competent person at specified intervals to ensure they function correctly when needed.
A malfunctioning safety valve can fail to protect a system from over-pressurisation, potentially leading to catastrophic failure. Similarly, failed steam traps can cause water hammer, energy waste and damage to downstream equipment. Regular examination of these devices is essential for both safety and operational efficiency.
Our examinations cover visual inspection, functional testing of set pressures, seat tightness assessment, and verification that each device operates within its design parameters. We also examine strainers, filters and associated pipework connections that form part of the pressure system.
Key Requirements
- Safety valves must be included in the written scheme of examination
- Set pressure verification and seat tightness testing required
- Steam traps must be examined for correct operation and efficiency
- Defective protective devices must be replaced or repaired immediately
- Examination records must be maintained and available for inspection
Equipment We Inspect
Our pressure systems engineers examine all types of valves, steam traps and filtration devices, including:
What We Check
Valves & Relief Devices
- Valve body, bonnet and flange condition
- Set pressure verification against design specification
- Seat tightness and leak testing
- Spindle, spring and lifting mechanism operation
- Bursting disc condition and correct rating
Steam Traps & Filters
- Steam trap discharge and operation assessment
- Temperature differential testing across traps
- Ultrasonic testing for passing or failed traps
- Strainer basket and filter element condition
- Connection integrity and isolation valve operation
Our Inspection Process
