EN 10219 S235JRH Carbon Steel Welded Pipe
S235JRH is a structural steel grade that complies with European standard EN 10210-1. The "S" stands for structural steel. This type of steel is mainly used in fields such as building structures and has excellent mechanical properties and processing properties. "235" indicates the minimum yield strength of this steel, in megapascals (MPa), which is about 235MPa, which means that this steel will not easily deform or break when subjected to a certain degree of pressure or tension. "J" means that the steel has a tested impact energy of 27 Joules at 20 degrees Celsius, which is suitable for low-temperature applications and has good low-temperature impact toughness. "RH" indicates that the steel is suitable for hot rolling or normalized hot rolling, that is, the steel can obtain the best mechanical properties and processing properties when processed at high temperatures.
S235JRH spiral steel pipe, also known as spiral submerged arc welded pipe, is manufactured in a spiral or spiral shape.
S235JRH SSAW steel pipe is widely used in various purposes such as water supply, oil and gas transportation, piling engineering and structural support.
