Mechanical Properties

The mechanical properties of Welded Steel Tube P275NL1, EN-10217-3, are specified in the standard and are as follows:

Steel name: P275NL1

Steel number: 1.0488

Tensile strength: 390-510 Mpa

Yield strength: 275 MPa minimum

Elongation: 23% minimum

Impact strength: Longitudinal (L): 27 J minimum at -50°C, Transverse (T): 16 J minimum at -50°C

These mechanical properties ensure that the welded steel tube can withstand the intended pressure and temperature conditions and maintain its structural integrity. The yield strength is the minimum stress at which the steel tube will deform permanently, while the tensile strength is the maximum stress that the tube can withstand before it fractures. The elongation is the percentage of deformation that the tube undergoes before it fractures, and it indicates the ductility or the ability of the material to deform without breaking. The Charpy V-notch impact test measures the energy required to fracture the steel tube under low-temperature conditions, and it is an indicator of the material's toughness or resistance to brittle fracture.

Inspection and testing

EN-10217-3 is a European standard that specifies the technical delivery conditions for welded steel tubes for pressure purposes. P275NL1 is a grade of steel specified in this standard, which is primarily used in the production of pressure vessels and boilers.
Inspection and testing of welded steel tube P275NL1, EN-10217-3, involves several steps to ensure that the tube meets the required standards and specifications. The following are some of the key aspects of inspection and testing:
1. Visual inspection: The surface of the welded steel tube is inspected for any surface defects such as cracks, porosity, and inclusions.
2. Dimensional inspection: The tube is checked for its dimensions such as diameter, wall thickness, and length, to ensure that it meets the required specifications.
3. Ultrasonic testing: This technique is used to detect any internal defects such as cracks or voids that are not visible through visual inspection. Ultrasonic testing involves the use of high-frequency sound waves to detect flaws.
4. Chemical analysis: The steel composition is checked to ensure that it meets the required standards and specifications.
5. Tensile testing: This test measures the strength of the tube by applying a tensile load until it breaks. This helps to determine if the tube has sufficient strength to withstand pressure and other loads.
6. Impact testing: This test measures the toughness of the steel by subjecting it to impact from a pendulum or striker. This is important in determining the resistance of the steel to brittle fracture.
7. Hydrostatic testing: This test involves filling the tube with water and subjecting it to pressure to ensure that it can withstand the required pressure without leaking or bursting.
Overall, the inspection and testing of welded steel tube P275NL1, EN-10217-3, are crucial to ensure that the tube meets the required standards and specifications for use in pressure vessels and boilers

Pressure and Temperature Ratings of

The pressure and temperature ratings of welded steel tube P275NL1, EN-10217-3, depend on various factors such as the tube size, wall thickness, and the intended application.
The pressure rating of a tube is typically determined based on its allowable stress, which is a function of the tube's material properties and the maximum allowable operating temperature. The temperature rating of a tube is determined by its ability to withstand thermal stresses and deformation at elevated temperatures.
For P275NL1 steel tubes manufactured according to EN-10217-3 standard, the allowable stress values and temperature ratings can be determined based on relevant code or standard such as EN 13445-3 or ASME BPVC Section II Part D. The below is a general indication of the maximum allowable pressure and temperature rating of P275NL1 steel tube according to EN-10217-3:
Maximum allowable pressure for P275NL1 steel tube:
• at room temperature: 20 bar (290 psi)
• at 100°C (212°F): 17.5 bar (254 psi)
• at 200°C (392°F): 16.0 bar (232 psi)
• at 300°C (572°F): 14.5 bar (210 psi)
Maximum allowable temperature for P275NL1 steel tube:
• for continuous service: 400°C (752°F)
• for intermittent service: 450°C (842°F)
It is important to note that these values are for general reference only and actual pressure and temperature ratings may vary depending on the specific application and operating conditions. Therefore, it is recommended to consult relevant codes, standards, or an experienced engineer to determine the precise pressure and temperature ratings for a particular application.

Standard marking for welded steel tubes

Welded steel tubes of P275NL1 grade, manufactured in accordance with EN-10217-3 standard, must be marked with specific information to ensure proper identification and traceability. The standard marking should include the following:
1. Manufacturer's name or trademark
2. The standard number (EN 10217-3)
3. The steel grade (P275NL1)
4. The heat number, which is a unique identifier assigned to a specific batch of steel during production
5. The manufacturing process (welded)
6. The outside diameter (OD) and wall thickness (WT) of the tube
7. The length of the tube
8. The date of production or a code indicating the production shift
The marking should be applied on the tube at regular intervals and should be clearly visible and legible. The information provided in the marking is important for quality control, inspection, and certification purposes. It allows the tube to be traced back to its origin and ensures that it meets the required standards and specifications.

Standard packing for steel Tubes

The standard packing of welded steel tube P275NL1, EN-10217-3, is important to ensure that the tubes are protected during transportation and storage. The tubes should be packed in such a way that they are not damaged or deformed, and are kept free from contamination. The following are some of the typical packing options:
1. Bundles: The tubes are packed in bundles with steel straps or plastic straps. The bundles are securely fastened to prevent any movement during transportation. The number of tubes in a bundle may vary depending on the tube size and length.
2. Wooden crates: The tubes may be packed in wooden crates to provide additional protection against mechanical damage. The crates should be made of durable wood and should be securely fastened with nails or screws.
3. Plastic caps: The ends of the tubes may be covered with plastic caps to prevent any contamination or damage to the tube ends. The caps should be securely fastened to prevent them from falling off during transportation.
4. Protective wrapping: The tubes may be wrapped with a protective material such as plastic film or paper to prevent scratches or abrasions during transportation.
5. Identification: The packing should be clearly labeled with information such as the tube size, wall thickness, length, and heat number for easy identification and traceability.
The specific packing requirements may vary depending on the customer's needs, transportation mode, and destination. Therefore, it is important to consult with the manufacturer or supplier to ensure that the tubes are packed properly and meet the required specifications.
