EN10216-2 P265GH Seamless Alloy Steel U Bend Tube For Gas Line
EN 10216-2 is a European standard that specifies the technical delivery conditions for seamless non-alloy and alloy steel tubes for pressure purposes with specified elevated temperature properties.
The characteristics of P265GH seamless steel pipe mainly include the following aspects:
First of all, P265GH seamless steel pipe has high strength and toughness and can withstand stress and vibration in high temperature and high pressure environments, so it is very suitable for the manufacturing of pressure vessels, boilers and other equipment.
Secondly, the chemical composition, mechanical properties and processing performance of P265GH seamless steel pipe all meet the relevant standard requirements, and its quality stability and reliability are very high.
Finally, the surface of P265GH seamless steel pipe is smooth, has no oxide layer or rust, and will not cause pollution or corrosion to the medium. It is very suitable for high-precision transmission media.
In short, P265GH seamless steel pipe is a very high-quality steel with many advantages and characteristics, and has very important application value in the manufacture of pressure vessels, boilers and other equipment.
