Product Introduction

EN 10219 hollow section Description

EN 10219 welded pipe is a welded steel pipe that complies with the international standard EN 10219, which is formulated for cold-formed welded hollow profiles of non-alloy and fine-grained structural steel to ensure that the product meets industrial requirements in terms of structural integrity, safety and performance. ‌

This type of welded pipe is usually produced by straight seam submerged arc welding process (such as JCOE process), with the characteristics of high strength, corrosion resistance and uniform welds, and is often used to manufacture large-diameter pipes. ‌ Its application areas are wide, including oil and gas pipelines, container pipelines, high-rise building structures and offshore platforms.

EN10219 standard specification

This Part of this European Standard specifies the technical delivery requirements for cold formed welded structural hollow sections of circular, square or rectangular form and applies to structural hollow
sections formed cold without subsequent heat treatment.
The specified requirements apply to non-alloy quality steel, fine grain non-alloy quality steel and fine grain alloy special steels as defined in EN 10020.
The grades, chemical composition and mechanical properties for the non-alloy quality steels are given in annex A.
The grades, chemical composition and mechanical properties for the fine grain non-alloy quality and alloy special steels are given in annex B.
The products specified in this Part of this European Standard are intended for use in construction.
NOTE. A range of steel grades is specified in this European Standard and the user should select the grade appropriate to the intended use and service conditions.The grades and mechanical properties of the finished hollow sections are compatible with those in EN 10025 and EN 10113 and some of those in EN 10149.
Requirements for tolerances, dimensions and sectional properties are contained in Part 2 of this European Standard (EN 10219-2).
