EN10216-1 Seamless Hot Rolled And Cold Drawn Steel Tube And Pipe
Material, Specification, Key Features
EN10216-1 is a European standard for seamless steel tubes for pressure purposes, which covers non-alloy steel tubes with specified room temperature properties. These tubes are intended for use in high temperature and pressure applications such as steam pipelines, power plants, and petrochemical plants. The standard specifies the technical delivery conditions for both hot rolled and cold drawn tubes.
Key Features
Seamless construction ensures uniformity and strength.
Suitable for high-pressure environments.
Available in hot rolled and cold drawn variants to meet different application requirements.
