Pipework - Stripwound metal hoses and hose assemblies (ISO 15465:2004)

ISO 15465:2004 specifies the requirements for the design, manufacture and testing of four principal types of stripwound metal hose and hose assemblies, of which only one type is for pressure applications. The four are: single overlap, unpacked and packed; double overlap, unpacked and packed, the last of these having maximum permissible pressures of up to 40 bar.
These hoses and hose assemblies may be supplied in nominal sizes from DN 6 to DN 500 and may operate at temperatures up to 600 °C dependent on materials of construction.

Rohrleitungen - Gewickelte Metallschläuche und Schlauchleitungen (ISO 15465:2004)

Diese Internationale Norm legt die Anforderungen für die Konstruktion, Herstellung und Prüfung von vier Haupt-typen von gewickelten Metallschläuchen und Schlauchleitungen fest, von denen lediglich eine Bauart für Anwendungsfälle unter Druckbeanspruchung vorgesehen ist. Die vier Bauarten sind: Schläuche mit einfacher Über-lappung, mit oder ohne Dichtung, sowie mit doppelter Überlappung, mit oder ohne Dichtung, wobei für letztere     maximal zulässige Drücke bis 40 bar gelten.
Diese Schläuche und Schlauchleitungen können in Nennweiten DN 6 bis DN 500 geliefert werden und je nach den für die Herstellung verwendeten Werkstoffen bei Temperaturen bis 600 °C betrieben werden.

Tuyauteries - Tuyaux et tuyauteries métalliques flexibles agrafés (ISO 15465:2004)

L'ISO 15465:2004 spécifie les exigences pour la conception, la fabrication et les essais des quatre principaux types de tuyaux et tuyauteries métalliques flexibles agrafés, dont un seul type est destiné aux applications sous pression. Les quatre types sont: agrafage simple, sans joint et avec joint, et agrafage double, sans joint et avec joint, ce dernier type ayant des pressions maximales admissibles inférieures ou égales à 40 bar.
Ces tuyaux et tuyauteries flexibles peuvent être fournis dans des diamètres nominaux de DN 6 à DN 500 et peuvent être utilisés à des températures inférieures ou égales à 600 °C en fonction des matériaux de fabrication.

Overview

EN ISO 15465:2004 - Pipework: Stripwound metal hoses and hose assemblies (ISO 15465:2004) defines requirements for the design, manufacture and testing of stripwound metal hoses and hose assemblies. It consolidates earlier stripwound hose standards into a single base document covering four principal hose types (single- and double-overlap, both unpacked and packed). Hoses are specified in nominal sizes DN 6 to DN 500 and may be used at temperatures up to 600 °C depending on materials. Only the double-overlap packed design is specified for pressure applications (maximum permissible pressures up to 40 bar).

Key topics and technical requirements

• Hose types
  • SOU - single overlap, unpacked
  • SOP - single overlap, packed
  • DOU - double overlap, unpacked
  • DOP - double overlap, packed (pressure-capable)
• Materials
  • Carbon steel (plain or protected), austenitic/ferritic stainless steels, bronze/brass for strip material.
  • Packing materials: cotton, glass fibre, polyamine, polyester, rubber, copper (as applicable). Asbestos is not permitted.
• Dimensions & performance
  • Nominal internal/external diameters, bend radii and allowable pressures are given in tables within the standard.
  • Hoses are supplied to ordered length with tolerance (typically ±3%) measured in mid or extended position.
• Mechanical tests
  • Tensile strength, crush strength, and bend radius tests (clauses 7.1–7.3).
  • Pressure test and production pressure-proof tests apply for pressure-type (DOP) hoses.
• Information from purchaser
  • The purchaser must specify application, nominal size/length, hose type, max operating pressure, temperature range, materials, and fittings. Additional data (media, velocity, movement, service life, cleaning, certificates) should be supplied when relevant.

Practical applications

• Used where flexible metallic connections are required in pipework exposed to high temperature, movement or vibration:
  • Industrial process piping (chemical, petrochemical)
  • Power plants and boiler exhaust systems
  • HVAC and ducting for high-temperature gases
  • Engine and turbine exhaust and flex connections
  • Any system requiring metallic flexibility with controlled leak characteristics
• The standard helps ensure compatibility, safety and repeatable testable performance for manufacturers, specifiers and purchasers.

Who should use this standard

• Hose and hose-assembly manufacturers and fabricators
• Piping and mechanical engineers specifying flexible connections
• Procurement and quality assurance teams verifying supplier compliance
• Maintenance and inspection teams assessing replacement and lifecycle requirements

ISO 15465:2004(E) iv © ISO 2004 – All rights reserved Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 15465 was prepared by Technical Committee ISO/TC 5, Ferrous metal pipes and metallic fittings, Subcommittee SC 11, Metal hoses and expansion joints. This first edition of ISO 15465 cancels and replaces ISO 7657:1995, ISO 7658:1984, ISO 8444:1985, ISO 8445:1995, ISO 8446:1995, ISO 8447:1986, ISO 8448:1986, ISO 8449:1995 and ISO 8450:1986 of which it constitutes a technical revision.

ISO 15465:2004(E) © ISO 2004 – All rights reserved v Introduction It was decided to produce an International Standard under the Vienna Agreement, on technical cooperation between ISO and the European Committee for Standardization, CEN, in order to maintain one document. The opportunity was taken to replace all existing stripwound standards into this single document and to reformat it such that its layout is similar to the Internatioanl Standard for corrugated hose, ISO 10380. At the same time, additional information has been included which was not available when the replaced standards were originally produced. This document is a base standard for stripwound metal hoses and hose assemblies for general purposes.
