EN 10208-2 L245NB L290NB L360NB L415NB L360QB Gas Steel Pipe Alloy Seamless Steel Pipe for Combustible Fluids

Material

EN 10208-2 specifies the technical delivery conditions for seamless and welded steel pipes used for the conveyance of combustible fluids. The pipes are manufactured from alloy steel, which provides enhanced mechanical properties and resistance to high temperatures and pressures.

Specification

The pipes are categorized based on their nominal diameter and wall thickness, ensuring they meet specific requirements for pressure and temperature ratings. The standard outlines the necessary testing and inspection procedures to ensure quality and safety.

Key Features

• Seamless Construction: Provides uniform strength and eliminates the risk of weld defects.
• High Strength: Suitable for high-pressure applications.
• Corrosion Resistance: Enhanced resistance to corrosive environments.
• Manufacturing: Tight tolerances for dimensional accuracy.
