Overview
EN ISO 6553:2017 is an international standard specifying mandatory and optional marking requirements for automatic steam traps. Developed jointly by ISO Technical Committee ISO/TC 153 "Valves" and CEN/TC 69 "Industrial valves," this standard ensures consistent labelling and identification of automatic steam traps used in various industrial applications. It supersedes the previous EN 26553:1991 and aligns markings with related international standards such as ISO 5209 and EN 19.
Automatic steam traps are critical components in steam systems, designed to discharge condensate and non-condensable gases without letting steam escape. Proper marking per EN ISO 6553:2017 facilitates safe, efficient use, installation, inspection, and maintenance of these devices.
Key Topics
Mandatory Markings:
Each automatic steam trap must include the:- Manufacturer’s name and/or trademark.
- Maximum allowable pressure in bar or MPa.
- Maximum allowable temperature in °C.
- Flow direction indication (arrow).
- Shell material designation (optional for sizes ≤ DN 50 or NPS 2).
- Nominal size (DN or NPS).
- Nominal pressure (PN or Class designation).
These markings may appear directly on the body or on permanently attached plates and must always remain visible, unobstructed by fixing elements.
Optional Markings:
Markings such as maximum operating pressure or maximum differential pressure, and maximum test pressure may be included to provide additional operational information.Additional Markings:
Manufacturers may add any other relevant markings to aid identification or traceability. Common additions include catalogue item numbers, provided no confusion arises with mandatory markings.Compliance with Related Standards:
The marking requirements are fully compatible with ISO 5209 (industrial valve marking) and EN 19 (metallic valve marking), promoting harmonized identification across valve types.
Applications
EN ISO 6553:2017 is applicable to all industrial sectors utilizing steam systems where automatic steam traps are installed, including:
- Power Generation: Ensuring safe and efficient energy production by correctly identifying steam trap ratings and performance limits.
- Chemical and Petrochemical Plants: Supporting precise maintenance and safety measures by providing clear markings that indicate pressure and temperature restrictions.
- Food and Beverage Industry: Assisting in compliance with hygiene and safety protocols by reliable trap identification.
- Heating, Ventilation, and Air Conditioning (HVAC): Facilitating proper steam trap monitoring and replacement for optimal system performance.
- Pulp and Paper Industry: Maintaining operational efficiency in steam-driven processes through clear trap marking.
By standardizing marking, EN ISO 6553:2017 helps improve steam system reliability, safety, and interoperability, reducing risks of incorrect installation or operation.
Related Standards
- ISO 6552: Automatic steam traps-Definition of technical terms ensuring clear communication about trap types and functions.
- ISO 5209: General purpose industrial valves-Marking providing a foundation for marking valves harmoniously across industries.
- EN 19: Industrial valves-Marking of metallic valves detailing marking practices for various valve types complementary to steam traps.
- ISO/IEC Directives: Editorial guidelines supporting consistent development and maintenance of ISO standards.
