Pressure and Temperature Ratings of

Welded Steel Tube P215NL, EN-10217-6 is a low-temperature austenitic steel grade designed for use in pressure vessels and piping applications. The pressure and temperature ratings of this steel tube depend on several factors, including its wall thickness, diameter, and the material's properties.
The maximum allowable pressure for Welded Steel Tube P215NL, EN-10217-6 can be determined using the following formula:
P = 2 * S * t / D
Where: P = Maximum allowable pressure (in bar) S = Allowable stress at the operating temperature (in MPa) t = Wall thickness of the tube (in mm) D = Outside diameter of the tube (in mm)
The allowable stress at the operating temperature is determined based on the material's mechanical properties, and it varies depending on the temperature. For Welded Steel Tube P215NL, EN-10217-6, the allowable stress at different temperatures can be found in the EN-10217-6 standard.
The maximum allowable pressure also depends on the operating temperature of the tube. The maximum allowable pressure decreases as the operating temperature increases. The temperature rating of Welded Steel Tube P215NL, EN-10217-6 is -50°C to 150°C.
It is important to note that the maximum allowable pressure and temperature ratings are based on several assumptions, including the quality of the weld, the surface condition of the tube, and the operating conditions. Actual operating conditions may differ from these assumptions, and it is essential to consider all factors when selecting and using Welded Steel Tube P215NL, EN-10217-6 in a specific application.
In conclusion, the pressure and temperature ratings of Welded Steel Tube P215NL, EN-10217-6 depend on the material's mechanical properties, wall thickness, diameter, and operating temperature. It is crucial to consider all of these factors when selecting and using this steel tube in pressure vessels and piping applications.
