The mechanical properties of the tube ensure that it can withstand the extreme operating conditions of these applications while maintaining its structural integrity.

Inspection and testing

Inspection and testing are important aspects of ensuring the quality of Welded Steel Tube P265GH as per EN-10217-2 standard. The following are the various inspection and testing methods that are performed on the tube:
1. Visual inspection: This is the initial inspection method carried out on the tube to detect any visible defects or imperfections such as cracks, voids, and surface finish.
2. Dimensional inspection: This inspection method is used to check the dimensions of the tube to ensure they are within the specified tolerances.
3. Non-destructive testing: This testing method includes various techniques such as ultrasonic testing, magnetic particle testing, and radiographic testing. These techniques are used to detect any internal defects in the tube such as cracks, voids, and inclusions.
4. Tensile testing: This test is performed to determine the tensile strength, yield strength, and elongation of the tube. This test involves applying a tensile load to the tube until it breaks, and the resulting data is used to determine the mechanical properties of the tube.
5. Charpy impact testing: This test is performed to determine the impact strength of the tube. This test involves striking the tube with a pendulum at a specific temperature, and the energy absorbed during the fracture is measured.
6. Hydrostatic testing: This test is performed to determine the resistance of the tube to internal pressure. The tube is filled with water and pressurized to a specific level, and the resulting data is used to determine the pressure rating of the tube.
7. Chemical analysis: This test is performed to determine the chemical composition of the tube to ensure it meets the specified requirements.
Inspection and testing are essential to ensure that Welded Steel Tube P265GH meets the required quality standards and specifications. The results of these tests provide assurance to customers that the tube is suitable for their intended application and can withstand the extreme operating conditions.

Pressure and Temperature Ratings of

The pressure and temperature ratings for Welded Steel Tube P265GH as per EN-10217-2 standard depend on several factors, such as the diameter, wall thickness, and the intended application of the tube. The ratings are determined by considering the mechanical and physical properties of the tube and the working conditions, such as the temperature, pressure, and the medium being transported.
Generally, the maximum allowable pressure for Welded Steel Tube P265GH at different temperatures can be calculated using the following formula:
P = 2SE/(D-2ST)
Where: P = maximum allowable pressure in bar S = allowable stress of the material in N/mm² E = quality factor for the material (typically 1) D = outside diameter of the tube in mm T = wall thickness of the tube in mm
The allowable stress (S) and quality factor (E) depend on the temperature and the manufacturing standard used. For instance, at room temperature, the allowable stress of P265GH is around 200 MPa, and the quality factor is 1.0.
The temperature rating of Welded Steel Tube P265GH is dependent on the material's ability to withstand thermal stress and mechanical properties at high temperatures. At room temperature, the tube can typically withstand pressures up to 20 bar, and temperatures up to 300°C. However, at elevated temperatures, the pressure rating will decrease due to reduced material strength.
It is important to consult the relevant codes and standards and perform the necessary calculations to determine the pressure and temperature ratings for specific applications. This ensures that the tube is used safely and effectively in the intended application.

Standard marking for welded steel tubes

The standard marking for Welded Steel Tube P265GH, EN-10217-2 includes important information about the tube's specifications and properties. The marking ensures that the tube is traceable and helps to verify its compliance with the required standards. The following information is typically included in the standard marking:
1. Manufacturer's name or trademark
2. Tube type – "Welded Steel Tube"
3. Steel grade – "P265GH"
4. Standard – "EN 10217-2"
5. Dimensions – outside diameter (OD) and wall thickness (WT) of the tube
6. Heat number – a unique identification number assigned to the specific batch of tubes produced
7. Batch or lot number – identification number used for tracking purposes
8. Country of origin – the country where the tube was manufactured
9. Inspection and certification marks – symbols indicating that the tube has been inspected and certified by a third-party organization.
The marking is typically printed or embossed on the tube's surface at regular intervals, usually every meter. The markings ensure that the tube can be easily identified and traced throughout its lifecycle, from production to installation and use. It also helps to prevent the use of non-compliant or counterfeit tubes, which can pose a safety risk and affect the overall performance of the system in which they are used.

Standard packing for steel Tubes

The standard packing for Welded Steel Tube P265GH, EN-10217-2 typically includes the following:
1. The tube is usually bundled with steel straps or wire ties to secure it in place during transport and handling.
2. Plastic caps are fitted on both ends of the tube to protect the inside surface and threads from damage and contamination.
3. The tube is then wrapped in a waterproof material, such as plastic or tarpaulin, to protect it from moisture and environmental factors.
4. The bundle is typically placed on a wooden or metal pallet to facilitate loading and unloading and to protect the tubes from damage during transport.
5. Finally, the bundle is strapped or wrapped with additional material to secure it in place during transport and handling.
