EN10216-2 TC2 P235GH 1.0345 Seamless Boiler Tube
EN 10216-2 is a European standard that specifies the technical delivery conditions for seamless steel tubes for pressure purposes. The standard includes several types of steel grades suitable for different applications under pressure.
TC2 in EN 10216-2 refers to the specific type or grade of steel tube being referred to. However, it's important to note that "TC2" isn't commonly referenced in this standard; typically, you might see references to types like D1, D2, etc., which refer to different steel grades.
P235GH is a specific steel grade mentioned in EN 10216-2. Here's what the designation means:
- **P**: Indicates that the steel is intended for pressure equipment.
- **235**: Represents the minimum yield strength in MPa (megapascals).
- **G**: Specifies the heat treatment condition.
- **H**: Indicates that the steel has been normalized or thermomechanically rolled.
P235GH is a common grade used for boiler and superheater tubes due to its good mechanical properties and weldability. It is suitable for use in steam boilers and other pressure vessels where the working temperature does not exceed approximately 450°C.
So, if you're referring to a P235GH tube under EN 10216-2, you're talking about a seamless steel tube with a minimum yield strength of 235 MPa, suitable for high-pressure applications such as in boilers and similar equipment.
