EN 10216 Seamless Steel Tube for High Temperature

Send Message Request a Quote

The seamless steel tube complies with EN 10216 standard, and can be applied at high temperature. Its steel grade is P355N, P355NL1 or P355NL2. With high strength and good structure stability, the high pressure steel pipe is resistant to oxidation and corrosion, which enables the tubular product to be used under the condition of high temperature and high pressure, such as the environment of high temperature flue gas and vapor. It may be used to produce the reheater tube, air tube, main steam line and the superheater tube of high pressure or super-high pressure boiler. When functioning as a commonly used boiler tube, the seamless steel tube can be applied in temperature below 450℃.
