EN 10216-2 P265GH Seamless Steel Pipes Tubes For Pressure Purposes
EN 10216-2 P265GH seamless steel pipes are non-alloy carbon steel tubes designed for high-temperature pressure applications such as boilers, heat exchangers, and pressure vessels. With a minimum yield strength of 265 MPa and excellent weldability, P265GH pipes are widely used in power plants and industrial piping systems.
We are a professional manufacturer of EN 10216-2 P265GH Seamless Steel Pipes Tubes For Pressure Purposes in China.
What is EN 10216-2?
EN 10216-2 is a European standard specifying seamless steel tubes for pressure purposes, particularly for:
- Elevated temperature service
- Boilers and pressure vessels
- Heat exchangers and pipelines
It belongs to the EN 10216 series for pressure applications
EN 10216-2 falls under the broader EN 10216 series, which covers seamless steel tubes intended for use in pressurized systems. The “-2” part of the standard refers to a specific section for carbon and carbon-manganese steel tubes, designed for use in high-temperature conditions
What is P265GH Steel?
P265GH is a non-alloy carbon steel grade designed for pressure equipment.
Grade Meaning:
- P = Pressure purpose
- 265 = Minimum yield strength (265 MPa)
- GH = Suitable for high-temperature service
The DIN EN 10216-2 standard specifies the requirements for seamless non-alloy and alloy steel tubes for specified elevated temperature conditions. Primarily used in the construction of pressure equipment such as boilers, heat exchangers, and pipelines.
Characteristics of P265GH Steel
P265GH is a carbon steel known for its excellent weldability, high-temperature resistance, good mechanical strength, and cold-bending performance. It performs well under pressure, making it ideal for boilers, pressure vessels, and heat exchangers. Its durability and resistance to moderate corrosion make it suitable for the power generation, oil, and gas industries. Alternatives like P355GH, 16Mo3, or 13CrMo4-5 may be more appropriate if higher strength or better corrosion resistance is needed.
