BS EN 10255 Pipe Standard Specification

What is BS EN 10255 Pipe Standard?

BS EN 10255 Piping, also known as “Non-alloy steel pipes suitable for welding or threading”, is a widely used European piping standard that specifies the technical delivery conditions for non-alloy steel pipes with specified room temperature pressure and normal service characteristics.
One of the main advantages of the BS EN 10255 piping standard is its versatility. These pipes can be used in a wide range of applications, including the construction industry for structural and mechanical purposes, and the gas and water distribution industry for the transport of fluids.
The standard also includes specific requirements for the chemical composition, mechanical properties and testing of these pipes to ensure that they meet the necessary safety and quality standards. In addition, the standard includes different types of pipes, such as flat-end pipes and threaded and socket-end pipes, providing manufacturers and users with more options.
Another advantage of the BS EN 10255 piping standard is that it is compatible with other international standards such as ASTM A53 and EN 10217-1, making it easy for manufacturers and users to comply with multiple standards at the same time.
The BS EN 10255 pipeline standard is an important tool for ensuring the safety and quality of non-alloy steel pipes, and its compatibility with other international standards makes it a convenient choice for manufacturers and users worldwide.
