Inspection of steam traps

Barthel Armaturen provides testing, maintenance, and evaluation of steam traps as a technical service for operators of steam systems. The focus is on a systematic evaluation of the condition of all manufacturers' products, with clear documentation, practical assessment, and optional replacement or repair of defective traps. The testing is carried out during normal operation without interrupting the production process.

From production and energy supply to food, chemicals, pharmaceuticals, and mechanical engineering, our service is suitable for industrial facilities in a wide range of industries. 

Why regular inspection is important

Steam traps drain condensate without losing steam. Over time, deposit build-up, corrosion, or leaks can often affect their function without being noticed.

• Leaking steam traps lead to higher energy and water consumption, rising operating costs, and additional strain on the steam system. At the same time, the unnecessary loss of steam significantly worsens the CO₂ balance of the system

• Blocked steam traps hinder drainage, reduce heating capacity, and can cause water hammer

Drainage points with low condensate volumes, e.g., on branch lines, trace heating systems, or in isolated segments, are particularly sensitive. In these areas, even a small defect leads to visible steam loss, as the low condensate volume does not provide a compensating effect.

Without regular checks, experience shows that the failure rate is between 15 and 25 percent. With systematic annual inspections, this can often be reduced to less than 5 percent in practice.

Steam leakage directly impacts energy consumption and carbon footprint

According to GESTRA's practical data, a single defective steam trap causes approximately 720 euros in financial loss and 3,840 kg of CO₂ emissions per year. With 10 defective traps, the total is already at 7,200 euros and 38,400 kg of CO₂. In larger systems, the potential can quickly multiply: 50 defective traps can add up to over 36,000 euros and 192,000 kg of CO₂ annually.

How the service works

The inspection is carried out during operation. We use a GESTRA-certified inspection system with access to an extensive typology database. This allows us to inspect almost all commercially available brands, including models from ARI, Armstrong, SPIRAX, RIFOX, Yarvay, and TLV.

Our testing methods include

• Visual inspection using sight glasses
• Level measurement with upstream test chamber
• Ultrasonic measurement with VKP 41 (impact sound analysis)
• Optional: Telemonitoring for continuous control

What you get as part of the service

• Recording of all steam traps with type, specification and installation location
• Structured inspection with measurements and evaluation
• Documentation including evaluation of the condition of each arrester to identify measures to be taken
• If necessary: Replacement or repair by the Barthel Armaturen service team

Our service creates a solid foundation for your maintenance and can be easily integrated into audits and energy efficiency programs.
