EN 10220 Pipe Weight Chart

EN 10220 Standard Overview

EN 10220 is the European standard for dimensions and tolerances of seamless and welded steel pipes. EN 10220 has a wide range of applications, primarily in the oil and gas, chemical, construction, and water treatment industries.

This standard covers the outside diameter (OD) and wall thickness (WT) of steel pipes, providing clear guidelines and uniform specifications for engineering design and manufacturing, ensuring consistency and interchangeability of pipe products from different manufacturers.

This standard is often used in conjunction with EN 10216 (seamless steel pipe) and EN 10217 (welded steel pipe). The former defines material property requirements, while the latter specifies manufacturing processes and testing criteria. EN 10220 provides the foundation for dimensions and tolerances, serving as the core standard for dimensional control within the three systems.

EN 10220 Series

EN 10220 is divided into three series based on the degree of standardization of pipes and their accessories:

Series 1: The outside diameters of all accessories required for the construction of the piping system are standardized;

Series 2: The outside diameters of not all accessories are standardized;

Series 3: The outside diameters of only a very small number of accessories are standardized.

Calculation Form for EN 10220 Pipe Weight

EN 10220 provides a method for calculating the mass per unit length per meter.

M = (D-T) × T x 0.0246615

M is the mass per unit length in kg/m,

D is the specified outside diameter in millimeters,

T is the specified wall thickness in millimeters.

0.0246615 = Steel Density Factor (based on the carbon steel density of 7.85 kg/dm³).

The calculated value can also be applied to pipes with different densities, but must be multiplied by a factor.

For austenitic stainless steel, the factor is 1.015 (based on a density of 7.97 kg/dm³). For ferritic and martensitic stainless steels, the coefficient is 0.985 (this coefficient is based on a density of 7.73 kg/dm³).

This can be calculated based on the differential density values for each group of stainless steel grades provided in EN 10088-1.

EN 10220 Pipe Weight Chart: Series 1 

This series of pipes strictly adheres to international and industry standards for outer diameters, providing fully standardized fittings such as flanges, fittings, and elbows.

This complete standardization simplifies the design and installation process and reduces the need for non-standard parts and customization costs.

EN 10220 Pipe Weight Chart: Series 2 

The outside diameter of this type of pipe is standardized, but not all fittings are. Some standard fittings, such as flanges or elbows, can be purchased, while others may need to be custom-made, adding cost and complexity to the project.

EN 10220 Pipe Weight Chart: Series 3 

Special or unconventional pipe sizes often require a large number of custom fittings and components, increasing project design and implementation costs and extending procurement and production cycles.

FAQ

1. What is The Difference Between EN 10220, EN 10216 And EN 10217?

EN 10220: Specifies dimensions and tolerances;

EN 10216: Specifies material requirements for seamless steel pipes;

EN 10217: Specifies material and testing requirements for welded steel pipes.

Used together, these three standards comprehensively cover the design, manufacture, and inspection of pipelines.

2. What Types of Steel Does EN 10220 Apply To?

EN 10220 applies to a wide range of carbon steels, low-alloy steels, and stainless steels, including:

Structural and pressure steels such as S235, S355, P235, and P355;

Stainless steels such as 1.4301, 1.4404, and 1.4571;

and steel grades in the EN 10088 and EN 10210 series of standards.

3. What ASTM Equivalent is EN 10220?

EN 10220 corresponds to ASME B36.10M / B36.19M (dimensional standards).

It is typically used in conjunction with ASTM A530/A530M or ASTM A999/A999M.
