Ductile iron and steel wide tolerance couplings and flange adaptors for use with pipes of different materials: ductile iron, Grey iron, steel, PVC-U, PVC-O, PE, fibre-cement
EN 14525:2022

This document specifies the requirements and associated test methods applicable to wide tolerance ductile iron and steel couplings, stepped/reducing couplings and flange adaptors intended for use with pipe components made from a number of pipe materials (ductile iron, grey iron, PE in conformity with EN 12201-1 to EN 12201-5, PVC-U in conformity with EN ISO 1452-1 to EN ISO 1452-5, steel, fibre-cement), for providing a leak tight seal over a wide range of pipe outside diameters:
-   to convey water (e.g. water intended for human consumption );
-   with or without pressure;
-   to be installed below or above ground, inside or outside buildings.
This document is not intended to cover sewerage or gas applications, where additional requirements may be necessary.
This document specifies requirements for materials, dimensions and tolerances, mechanical properties and standard coatings of products.
This document covers wide tolerance couplings, stepped/reducing couplings and flange adaptors:
-   Manufactured with socketed or flanged ends;
-   Supplied externally and internally coated;
-   Suitable for ductile iron in conformity with EN 545, grey iron, PE in conformity with EN 12201-1 to EN 12201-5, PVC-U in conformity with EN ISO 1452-1 to EN ISO 1452-5, steel, fibre-cement in a size range extending from DN 40 to DN 700, for an allowable operating pressure (PFA) up to 16 bar, for fluid temperatures between 0 °C and 25 °C excluding frost. For higher temperatures, (up to 45 °C for PVC-U or 40 °C for PE) the PFA is derated as given in EN ISO 1452 and EN 12201;
-   Not intended for use in areas subjected to reaction to fire regulations.
NOTE 1   This does not preclude special arrangements for the products to be used at higher temperatures. Temperature limitations and pressure limitations are those coming from the PVC-U or PE pipes.
This document covers ductile iron couplings, stepped/reducing couplings and flange adaptors cast by any type of foundry process or manufactured by fabrication of cast components, as well as corresponding joints, in a size range extending from DN 40 to DN 700, to be used with pipes of external diameter from 40 mm to 710 mm.
As long as no equivalent European Standard exists for steel accessories, this document also covers couplings and flange adaptors which are fabricated partly or entirely from steel as well as corresponding joints, in a size range extending from DN 60 to DN 700, to be used with pipes of external diameter from 63 mm to 710 mm.
This document specifies requirements for materials, dimensions and tolerances, mechanical properties and standard coatings. It also gives minimum performance requirements for all components, including restrained and non-restrained flexible joints. Joint design and gasket shapes are outside the scope of this document.
NOTE 2   PFA can be limited depending on pipe materials effectively connected.
NOTE 3   In this document, if not specified, all pressures are relative gauge pressures, expressed in bars (100 kPa = 1 bar).

Flanges and their joints - Bolting - Part 4: Selection of bolting for equipment subject to the Pressure Equipment Directive 2014/68/EU
EN 1515-4:2021/AC:2022

This document is applicable to the selection of bolting for flanged joints on equipment subject to the Pressure Equipment Directive 2014/68/EU.
It specifies standards and additional requirements for dimensions, material properties and technical conditions of delivery for bolting.
NOTE 1   Washers are not within the scope of this document.
The selection is based on commonly used bolting. It covers common temperature ranges of the general service of flanges.
When selecting bolting according to this document it is essential to take into account environmental conditions and other parameters including type of fluids, corrosion hazards, sour service, low temperature brittle failure and relaxation at elevated temperatures.
The purpose of this document is to provide a selection of most commonly used bolting types and bolting material combinations.
It is not the intention to specify all possible applications but to give guidance on the most common applications. For example, application limits for material in the creep range are not explicitly covered in this document. Where material standard provides mechanical properties for the creep range respective reference is made in Table 3.
NOTE 2   Special services and ambient conditions may require the application of coatings. It is the purchaser’s option to decide on this. Depending on the coating used, a verification of the temperature ranges given in Table 3 and Table 4 may be required.
NOTE 3   In Annex B there are bolting types and bolting material combinations according to commonly used national standards other than those listed in Table 2, Table 3 and Table 4.

Flanges and their joints - Bolting - Part 4: Selection of bolting for equipment subject to the Pressure Equipment Directive 2014/68/EU
EN 1515-4:2021

This European Standard is applicable to the selection of bolting for equipment subject to the Pressure Equipment Directive 2014/68/EU.
It specifies standards and additional requirements for dimensions, materials and technical conditions of delivery for bolting.
The bolting selection covered by this European Standard is regarded to be used for combination with flanges according to the series EN 1092 (PN designated flanges) and the series EN 1759 (Class designated flanges).
The selection is based on commonly used materials, bolts and nuts. It covers temperature ranges of the general service of standard flanges (based on PN or Class).
NOTE 1   The bolting selection given may be used in combination with non-standard flanges too provided that the range of application of the equipment for which the bolting is intended to be used is covered. It is the purchaser's option to decide on this.
When selecting bolting according to this European Standard it is essential to take into account other parameters such as type of fluids, corrosion hazards and relaxation at elevated temperatures.
The purpose of this European Standard is to provide a selection of most commonly used bolting types and bolting material combinations as well a tool for easy selection of suitable bolting for equipment.
It is not the intention to specify all possible applications but to give guidance on the most commonly applications. According to this, e.g. application limits for material in the creep range are not explicitly covered in this European Standard but some bolting materials listed (see Table 3, footnote h) are suitable to be used in this temperature range. Wherever the starting material standard provides mechanical properties for this temperature range respective reference is made in Table 3.
NOTE 2   Special services and ambient conditions may require the application of coatings. It is the purchaser's option to decide on this. Depending on the coating used, a verification of the temperature ranges

Flanges and their joints - Design rules for gasketed circular flange connections - Part 1: Calculation
EN 1591-1:2013

This European Standard defines a calculation method for bolted, gasketed, circular flange joints. Its purpose is to ensure structural integrity and control of leak tightness. It uses gasket parameters based on definitions and test methods specified in EN 13555. The calculation method is not applicable to joints with a metallic contact out of the sealing face or to joints whose rigidity varies appreciably across gasket width. For gaskets in incompressible materials, which permit large deformations, the results given by the calculation method can be excessively conservative (i.e. required bolting load too high, allowable pressure of the fluid too low, required flange thickness too large, etc.).
