EN 10217-5 P235GH P265GH 16Mo3 Welded Steel Tube Submerged Arc Welded for High Temperature Service

Introduction

EN 10217-5 is a European standard that specifies the technical delivery conditions for welded steel tubes for pressure purposes. This article focuses on the P235GH, P265GH, and 16Mo3 grades of steel tubes, which are commonly used for high-temperature service. We will explore the material, specification, key features, chemical composition, mechanical properties, steel grade, application, and possible alternative grades.

Material and Specification

The EN 10217-5 standard covers welded steel tubes made from non-alloy and fine grain steels. The P235GH, P265GH, and 16Mo3 grades are specifically designed for high-temperature service. These tubes are manufactured using the submerged arc welding (SAW) process, which ensures excellent weld integrity and dimensional accuracy.

Key Features

The key features of EN 10217-5 P235GH, P265GH, and 16Mo3 welded steel tubes are as follows:

1. High-temperature resistance: These tubes are capable of withstanding elevated temperatures, making them suitable for applications involving heat transfer and pressure.
2. Good weldability: The submerged arc welding process used in their manufacturing ensures strong and reliable welds, contributing to the overall structural integrity.
3. Corrosion resistance: The steel tubes exhibit good resistance to corrosion, making them suitable for various industrial environments.
4. Dimensional accuracy: EN 10217-5 specifies strict tolerances and dimensional requirements, ensuring consistent and precise tube dimensions.
