EN 10216-2 P265GH Tubes are seamless and hot rolled carbon steel tubes suitable for pressure equipment applications, ensuring consistent performance at high temperatures and pressure. "P" is used to denote a pressure vessel steel grade, "265" for minimum yield strength 265 MPa, and "GH" shows that these tubes can be used for high temperature service conditions, as defined under this European standard for seamless non alloy and alloy steel tubes. With minimum tensile strength 450 MPa, yield strength 280 MPa, and elongation 22%, these tubes are suitable for use in oil refineries, steam pipes, power plants, and boilers. These tubes come in diameters of 10.2 to 711 mm with wall thicknesses of 1.6 to 100 mm. They can be obtained with varnish coating, black paint, or oil coating. As a trusted manufacturer, Amardeep Steel Centre supplies EN 10216-2 P265GH Tubes that meet stringent international quality and dimensional standards.
