European Pipes Dimensions & Weights Charts (EN 10220, EN ISO 1127)

The EN 10220 and EN 1127 specifications cover the dimensions and tolerances of European pipes, carbon/alloy steel, and stainless steel respectively. While EN 10220 and 1127 are used in Europe, ASME B36.10 and ASME B36.19 cover the dimensions and tolerances of American standard pipes.

EN 10220 Pipe Size Specification

The BS EN 10220 specification covers the dimensions and tolerances of carbon and low-alloy steel pipes manufactured (or installed) in Europe.

EN 10220:2002 is a European Standard that specifies the dimensions and tolerances of seamless and welded steel tubes for general purposes. This standard provides a range of size specifications, including outside diameters, wall thicknesses, and exact lengths of steel tubes, along with the associated tolerances for each. EN 10220 aims to standardize the dimensional specifications for steel tubes across Europe, facilitating interoperability and ensuring that tubes meet quality and performance expectations for a wide array of applications.

Key aspects of EN 10220 include:

1. Scope: It covers seamless and welded (except submerged arc-welded) steel tubes for pressure purposes, full peripheral magnetic testing for the detection of longitudinal imperfections, and ultrasonic testing for the detection of laminar imperfections.

2. Outside Diameter and Wall Thickness: The standard provides detailed charts specifying the permissible variations in outside diameter and wall thickness for steel tubes, which are crucial for ensuring the tubes are suitable for the intended pressure and structural requirements.

3. Length Tolerances: EN 10220 also specifies tolerances for the lengths of tubes, including standard lengths and permissible variations, which are essential for ensuring that tubes fit correctly within the designed piping or structural systems without the need for excessive modifications.

4. Tolerances on Shape: This includes straightness and roundness tolerances, ensuring that the tubes can be fitted and welded with precision in various configurations and applications.

By providing a comprehensive set of dimensional specifications and tolerances, EN 10220 helps to ensure the quality and compatibility of steel tubes used throughout Europe in construction, engineering, and manufacturing industries. This standardization facilitates the efficient design, specification, and procurement of steel tubes, contributing to the overall safety, reliability, and performance of piping systems and structural projects.

EN ISO 1127 Pipe Size Specification

The EN ISO 1127 specification covers the dimensions and tolerances of European stainless steel and nickel alloy pipes.

EN ISO 1127 is an international standard adopted by Europe that provides comprehensive details on the dimensions, tolerances, and conventional masses per unit length of stainless steel tubes. This standard is crucial for ensuring the compatibility and interchangeability of tubes in various applications. It covers a range of tube sizes, from small-diameter instrumentation tubing to larger-diameter industrial pipes.

Size Specifications Overview:

Outside Diameter (OD): Stainless steel pipes and tubes in Europe are often specified by their outside diameter. The range can vary significantly, from very small diameters for instrumentation tubes (e.g., a few millimeters) to large diameters for industrial applications (up to several hundred millimeters).

Wall Thickness: The standards specify a range of wall thicknesses, denoted by schedule numbers or directly in millimeters. The choice of wall thickness affects the pipe’s pressure rating and mechanical strength.

Pipe Length: Standard lengths are usually provided, but custom lengths can be ordered to meet specific project requirements.

Tolerances: The standards specify tolerances for dimensions (including outside diameter and wall thickness) to ensure that the pipes meet the precise requirements needed for their intended use.

These European standards facilitate the harmonization of technical specifications across member countries, promoting the efficiency and safety of stainless steel piping systems in various industries. When specifying stainless steel pipes for a project, it’s essential to refer to the relevant EN standards to ensure that the correct dimensions, tolerances, and technical delivery conditions are applied.

 

The OD (outside diameter) and WT (wall thickness) combinations of this specification match those of EN 10220.

  1. On looking at this further I note that all the values shown in the two charts – EN 10220 & EN 1127 are identical, so this assumes the density of the various alloys is always the same. This is not true, but given they show the same values, what is the purpose of having two charts?

    Also the sizes and wall thicknesses shown may be the full range of the relevant standards, but this gives no information on the availability of any given size. In my experience the standards show everything that is envisaged, not what is used in practise.

    How do these sizes compare with the relevant ANSI standards? A comparative chart would be useful.

  2. The meaning of these charts is unclear. Apparently the left column is the pipe OD, and the top row is the wall thickness – but this is not clearly stated. Then I must assume the numbers in the table are the mass, probably in kg/m, but this is not mentioned anywhere.

    Please clarify.
