Inspection and testing

Welded Steel Tube P355NH, as per EN-10217-3 standard, undergoes several inspection and testing procedures to ensure that it meets the required quality standards. Some of the common inspection and testing procedures include:
1. Visual inspection: The tube is visually inspected to check for any surface defects such as cracks, dents, or scratches.
2. Dimensional inspection: The tube is measured to ensure that it meets the required dimensions and tolerances.
3. Ultrasonic testing: Ultrasonic testing is conducted to detect any internal defects or flaws in the tube.
4. Tensile testing: Tensile testing is conducted to determine the mechanical properties of the tube, such as tensile strength and yield strength.
5. Charpy impact testing: Charpy impact testing is conducted to determine the impact energy of the tube at low temperatures.
6. Hydrostatic testing: Hydrostatic testing is conducted to test the tube's ability to withstand high pressure by subjecting it to a hydraulic pressure test.
7. Heat treatment: The tube may undergo heat treatment to improve its mechanical properties and remove any residual stresses.
All inspection and testing procedures are carried out in accordance with the EN-10217-3 standard and other relevant standards and regulations.

Pressure and Temperature Ratings of

The pressure and temperature ratings of Welded Steel Tube P355NH, as per EN-10217-3 standard, depend on several factors such as tube size, wall thickness, and operating conditions. Generally, the pressure and temperature ratings of the tube are determined by the design code or specification used for the application.
However, as a general guideline, the maximum allowable pressure and temperature for Welded Steel Tube P355NH can be estimated based on its mechanical properties and wall thickness. The maximum allowable pressure and temperature for the tube can be calculated using the following formulas:
Maximum allowable pressure (in bar) = (minimum yield strength x wall thickness) / (safety factor x weld joint efficiency)
Maximum allowable temperature (in °C) = (20 x tensile strength) / (1000 x safety factor)
Here, the safety factor and weld joint efficiency depend on the design code or specification used for the application. Typically, the safety factor ranges from 1.5 to 3, and the weld joint efficiency ranges from 0.7 to 1.0.
It is important to note that these are only estimates, and the actual pressure and temperature ratings may vary depending on the specific application and design code or specification used. Therefore, it is recommended to consult with a qualified engineer or design professional to determine the appropriate pressure and temperature ratings for Welded Steel Tube P355NH for a specific application.
