Overview
EN 14423:2013/prA1 is the CEN European standard (draft amendment A1, Jan 2016) covering clamp type coupling assemblies for steam hoses. It specifies the design, materials and dimensions of fittings for clamp couplings used with steam and hot‑water hoses in nominal sizes DN 15 to DN 50, for a maximum working pressure of 18 bar (saturated steam up to 210 °C). The amendment updates design details, material specifications and references to flange standards.
Key topics and technical requirements
- Scope and ratings
- Applicability: clamp type coupling assemblies for steam/hot‑water hoses DN 15–DN 50.
- Maximum working pressure: 18 bar (saturated steam temperature ≈ 210 °C).
- Design and dimensions
- Defines dimensional requirements for fittings and assemblies to ensure interchangeability and safe operation.
- Amendment includes renumbering of figures/tables for clarity (e.g., Figure/Table renames).
- Materials
- Updated material designations in prA1 (e.g., S355J0+N replacing former S355J2G3 references).
- Stainless steel designation updates (e.g., X2CrNiMo17‑12‑2 per EN 10088‑1).
- Clamps, bolts and nuts
- Requirements and references for clamp geometry, bolt and nut selection and assembly integrity are addressed; prA1 modifies related clause/table numbering.
- Tail ends and flanges
- Tail end fittings, weld‑neck collars and loose flanges are specified; material updates and cross‑references to EN 1092‑1 for flanges are included.
- Deleted items
- prA1 removes specific subclauses on hose fittings with coned end and stud end (7.3.6 and 7.3.7).
Applications and who uses this standard
- Primary users:
- Hose and coupling manufacturers designing and producing clamp type coupling assemblies.
- Plant engineers, procurement and specifiers in steam systems, power plants, food processing, chemical and pharmaceutical industries.
- Maintenance and safety engineers responsible for pressure‑rated hose assemblies and replacement parts.
- Testing laboratories and conformity assessment bodies verifying compliance with European requirements.
- Practical benefits:
- Ensures compatibility and interchangeability of fittings.
- Supports safety and pressure integrity for steam and hot‑water hose assemblies.
- Guides material selection to withstand steam temperatures and corrosive environments.
