P235GH, P265GH, P235TR1 ERW Tubes
EN 10216 Welded Pipe Supplier-GNEE
EN 10216-1 P235tr1 is treated in accordance with national and international standards. Components of this grade are used in high-temperature applications such as oil and gas, boiler equipment, heat exchangers, etc.P265gh Tc1 material is designed to have excellent mechanical properties. The tensile strength of the material ranges from 360 to 500mpa. They have a minimum yield strength of 235mpa and can be elongated by 25%.P235GH is a steel specified in Europe for pressure vessels, boilers and heat exchangers. The composition of this steel makes it ideally suited to high-temperature working applications and the material is used by manufacturers throughout the oil, gas and petrochemical industries.
