EN 10216-1 P235tr2 standard specifies Seamless steel tubes for pressure purposes. It is used for manufacturing pipeline, vessel, equipment, pipe fittings. The composition of P235tr2 Alloy Steel material makes it ideal for applications where elevated working temperatures are the norm and the material is used by fabricators throughout the oil, gas and petrochemical industry.
EN 10216-1 P235tr1 are mainly used for vessel and equipment structure use. It has a minimum tensile strength of 360 Mpa and maximum tensile strength 500 Mpa and has minimum yield strength of 235 Mpa.
EN 10216-1 P235tr2 Alloy Steel Seamless Pipe are used for producing storage tanks of heat-resistant steels used in boiler-making, tool-making and for constructing pressure reservoirs and high pressure and are simultaneously used to have summarized load and special conditions.
