S235JRH Spiral Welded Carbon Steel Pipe
S235JRH spiral welded pipe is a structural steel that complies with European standard EN 10210-1 and is mainly used in building structures and other fields.
Among them, "S" marks its identity as structural steel. The value "235" represents the minimum yield strength of the steel, which is approximately 235MPa, which means that when subjected to a certain pressure or tension, it can maintain a stable shape and is not prone to deformation or fracture.
The letter "J" indicates that the impact energy of this steel is 27 Joules at 20 degrees Celsius, showing its excellent impact toughness in low temperature environments. The "RH" signifies that this steel is suitable for hot rolling or normalizing hot rolling, ensuring optimal performance during high-temperature processing.
In addition, S235JRH spiral steel pipe, also known as spiral submerged arc welded pipe, is widely used in water supply, oil and gas transportation, piling engineering, structural support and other occasions due to its unique spiral shape.
