ÖNORM EN 1515-4

Issue date: 2021 06 01

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

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. 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.

Frequently Asked Questions about ÖNORM EN 1515-4

What is a "Single-User Licence"?

When you purchase a standard from the Austrian Standards webshop (e.g. ÖNORM, ISO), a single-user licence is included as standard. This entitles a single person to use the standard. A multi-user licence is required if several employees need access. It enables company-wide, legally compliant use and sharing of standards.
