Overview

EN 14423:2013+A1:2016/prA2:2018 is a European Standard developed by the CEN Technical Committee CEN/TC 218, focusing on clamp type coupling assemblies designed for steam and hot water hoses. This standard applies specifically to assemblies with nominal sizes ranging from DN 15 to DN 50 and rated for pressures up to 18 bar, corresponding to a saturated steam temperature of 210 °C. The document establishes clear requirements for the design, materials, and dimensions to ensure safety, reliability, and interoperability in high-pressure steam applications.

This standard is critical for manufacturers, engineers, and quality assurance professionals working with steam hose assemblies, helping to maintain consistent quality and safety across European markets. The document includes amendments and updates to ensure alignment with related norms and advances in technology.

Key Topics

• Design Specifications
  Outlines dimensions, tolerances, and functional characteristics for clamp type coupling assemblies ensuring compatibility with steam hoses rated for up to 18 bar.

• Material Requirements
  Defines the acceptable materials for components including metals and elastomers, ensuring resistance to steam temperature and pressure conditions.

• Nominal Sizes
  Covers coupling assemblies for sizes DN 15, DN 25, DN 32, DN 40, and DN 50, which are common dimensions for industrial steam hoses.

• Maximum Working Conditions
  Focuses on assemblies capable of withstanding working pressures up to 18 bar, equivalent to a saturated steam temperature of 210 °C.

• Loose Flanges Modification
  Includes specific technical amendments around loose flange materials aligned with EN 1092-1 and EN 10025-2 standards, addressing steel grade updates.

• Multilingual and Multinational Scope
  Available in English, French, and German; adopted by multiple European national standard bodies, harmonizing industry practices continent-wide.

Applications

• Industrial Steam Systems
  Clamp type coupling assemblies designed per EN 14423:2013+A1:2016/prA2:2018 are widely used in steam transfer, cleaning systems, and heating processes in manufacturing plants.

• Hot Water Hose Assemblies
  Besides steam, these couplings provide reliability for high-temperature hot water hoses in food processing, chemical industries, and HVAC applications.

• Maintenance and Safety
  Standardized couplings facilitate safe installation and maintenance of steam hoses, reducing risks of leakage or failure under operational pressure and temperature.

• Replacement Parts and Interoperability
  Enables interchangeability of hose assemblies and clamps among different manufacturers, ensuring consistent performance and simplifying inventory management.

• EN 1092-1 – Flanges and their design, materials, and dimensions impacting loose flange interfaces referenced in EN 14423 coupling assemblies.

• EN 10025-2 – Specifies technical delivery conditions for non-alloy structural steels such as S235JR and S355J0, used for metal parts in coupling assemblies.

• EN 14423:2013+A1:2016 – Previous edition of this standard, outlining baseline requirements before incorporation of amendment A2 in 2018.

• CEN/TC 218 – The technical committee responsible for rubber and plastics hoses and hose assemblies, ensuring comprehensive standardization across related products.

Practical Value

Adhering to EN 14423:2013+A1:2016/prA2:2018 is essential for manufacturers to produce clamp type coupling assemblies that meet stringent European safety and performance criteria. Implementing these standards supports compliance with legal regulations and enhances product durability in demanding steam applications. For engineers and facility operators, these standard assemblies optimize system integrity and reduce downtime caused by hose failures. Furthermore, consistent use of EN 14423 assemblies promotes market acceptance and facilitates smooth cross-border trade within Europe’s internal market.
