Pressure and Temperature Ratings

The pressure and temperature ratings of Stainless Steel Pipe X2CrNiMo17-12-2, EN-10217-7 depend on several factors, including the pipe size, wall thickness, and operating conditions.
According to EN 10217-7 standard, the maximum allowable pressure and temperature ratings for X2CrNiMo17-12-2 pipe are as follows:
• The maximum allowable pressure for X2CrNiMo17-12-2 pipe is calculated using the formula P = 2 SE / (1 + y), where P is the maximum allowable pressure, S is the minimum tensile strength of the material, E is the weld efficiency factor, and y is the safety factor. The safety factor is typically 1.5, and the weld efficiency factor is dependent on the type of weld used.
• The maximum allowable temperature for X2CrNiMo17-12-2 pipe is dependent on the maximum allowable pressure, the temperature of the fluid being transported, and the material's thermal properties. It is important to ensure that the pipe's maximum allowable temperature is not exceeded to avoid damage or failure.
For X2CrNiMo17-12-2 pipe with a diameter of 25mm and a wall thickness of 2.0mm, the maximum allowable pressure is approximately 85 bar (1232 psi) at room temperature (20°C), assuming a safety factor of 1.5 and a weld efficiency factor of 0.8. The maximum allowable temperature for this pipe is approximately 300°C at this pressure rating.
It is important to note that these values are general guidelines and may vary depending on the specific application and operating conditions. It is recommended to consult the relevant codes and standards and perform appropriate calculations and testing to ensure that the pipe is suitable for its intended use.
