Material Grade and Standards
Material Grade: E235 +N
Standard: EN10305-4
This product is manufactured in accordance with the EN10305-4 standard, which governs the production of precision seamless tubes. The material, E235 +N, is carbon steel with excellent mechanical properties, such as good tensile strength, machinability, and weldability. The +N designation indicates that the steel has been normalized, which improves its toughness and structural stability, making it ideal for demanding applications where high performance is critical.
The cold drawing process employed in the manufacturing of this seamless steel pipe ensures a smooth surface finish and precise dimensions. This process also enhances the mechanical properties of the steel, such as its strength and hardness, making it a suitable choice for applications involving high pressure, high temperature, or heavy mechanical stress.
Bright Annealed (BA):
The BA finish offers a highly reflective, smooth surface that not only enhances the appearance of the pipe but also improves its resistance to oxidation and corrosion. This finish is ideal for environments where cleanliness and corrosion resistance are important, such as in food processing, chemical, or pharmaceutical industries.
Black Phosphated (BP):
The BP coating adds a protective layer to the steel pipe, providing excellent corrosion resistance in harsh conditions. This coating also improves the pipe’s surface hardness, making it more resistant to wear and abrasion, which is beneficial in mechanical and automotive applications.
Galvanized:
The optional galvanized coating offers additional protection against rust and corrosion, especially in outdoor or exposed environments. This zinc coating acts as a sacrificial layer, preventing the steel beneath from oxidizing, thus extending the lifespan of the pipe.
Seamless Construction:
The seamless construction of the pipe eliminates weak points such as welded seams, resulting in uniform strength and resistance to pressure. This makes the pipe highly reliable in applications where safety and performance are essential, such as in hydraulic systems or high-pressure fluid transport.
Cold Drawn Precision:
The cold drawing process ensures a high level of precision, both in terms of internal and external diameters. This precise manufacturing process guarantees tight tolerances and a smooth finish, which are crucial for fluid systems requiring accurate flow control and minimal turbulence.
The EN10305-4 E235 +N Cold Drawn Seamless Steel Pipe is used in a variety of industries and applications due to its strength, precision, and corrosion-resistant properties:
