These chemical composition values may vary slightly depending on the specific production method and manufacturing process used for the welded steel tube.

Mechanical Properties

The mechanical properties of welded steel tube P275NL2, as per EN-10217-3, are as follows:

Steel name: P275NL2

Steel number: 1.1104

Tensile strength: 390-510 Mpa

Yield strength: 275 MPa minimum

Elongation: 23% minimum

Impact strength: -50°C / 27 Joules (longitudinal)

These properties are determined by conducting various tests on the steel, including tensile and impact tests, and measuring the resulting values. The yield strength of 275 N/mm² means that the steel can withstand a certain amount of stress before it starts to deform plastically. The tensile strength range of 390-510 N/mm² indicates the maximum amount of stress the steel can bear before it fractures. The elongation value of 23% measures the amount of deformation the steel can undergo before breaking, indicating its ductility. The impact strength value of 27 Joules indicates the energy required to fracture the steel under specific conditions, such as low temperatures. It's important to note that these values are specific to P275NL2 steel and may vary depending on the specific manufacturing process used, as well as the size and shape of the welded steel tube.

Inspection and testing

The inspection and testing of welded steel tube P275NL2, as per EN-10217-3, are critical to ensure its quality and compliance with the standard's requirements. The following are some of the common tests and inspections carried out on P275NL2 steel tubes:
1. Visual inspection: This involves a comprehensive visual examination of the welded steel tube, checking for surface defects, cracks, and other irregularities.
2. Dimensional inspection: This ensures that the welded steel tube conforms to the specified size and shape requirements, including diameter, length, and wall thickness.
3. Non-destructive testing (NDT): Various non-destructive testing methods, such as ultrasonic testing (UT), radiographic testing (RT), and magnetic particle testing (MPT), are carried out to identify any internal defects or flaws in the steel tube.
4. Mechanical testing: This involves testing the mechanical properties of the steel tube, such as tensile strength, yield strength, elongation, and impact strength, to ensure they meet the specified requirements.
5. Chemical analysis: Chemical composition analysis is performed to verify that the steel tube contains the required elements in the specified amounts.
6. Pressure testing: The welded steel tube is subjected to hydrostatic pressure to ensure it can withstand the required pressure.
7. Heat treatment verification: If heat treatment is required as per the standard, heat treatment verification is carried out to ensure that the steel tube has undergone the necessary heat treatment.
These inspections and tests help to ensure that the welded steel tube P275NL2 meets the required quality standards and is safe for its intended use in pressure vessel construction.

Pressure and Temperature Ratings of

The pressure and temperature ratings of welded steel tube P275NL2, as per EN-10217-3, depend on various factors such as the dimensions, wall thickness, and material properties of the tube. The following are some general guidelines:
1. Pressure ratings: The pressure rating of the welded steel tube P275NL2 is determined by its maximum allowable working pressure (MAWP), which is a function of its wall thickness, diameter, and yield strength. As per the standard, the maximum working pressure for P275NL2 steel tube is 10 bar at a temperature of 300°C.
2. Temperature ratings: The temperature rating of the welded steel tube P275NL2 is determined by its material properties, specifically its ability to withstand high temperatures without losing its strength or undergoing deformation. As per the standard, the maximum temperature for P275NL2 steel tube is 400°C.
It is important to note that these pressure and temperature ratings are general guidelines and may vary depending on the specific application, installation, and operating conditions of the welded steel tube. Therefore, it is critical to consult with the appropriate codes and standards and follow the manufacturer's recommendations to determine the specific pressure and temperature ratings for P275NL2 steel tube in a particular application.

Standard marking for welded steel tubes

Welded steel tube P275NL2, as per EN-10217-3, must be clearly marked to indicate its compliance with the standard and to provide traceability. The following are the standard markings required for P275NL2 steel tubes:
1. Manufacturer's mark: This is the mark or name of the manufacturer, supplier, or distributor of the welded steel tube.
2. Standard designation: This is the standard designation for P275NL2 steel tube, which is EN-10217-3.
3. Steel grade: This is the steel grade designation, which is P275NL2.
4. Dimensional and wall thickness information: This includes the outside diameter (OD), wall thickness, and length of the welded steel tube.
5. Heat number: This is a unique identifier for the heat of steel used to produce the welded steel tube.
6. Traceability code: This is a unique identifier assigned by the manufacturer to allow the steel tube to be traced back to the production process and material.
7. Additional markings: Additional markings may be required as per customer or application-specific requirements, such as the maximum allowable working pressure, temperature rating, or any special treatment or coating applied to the steel tube.
All markings must be legible and permanent, and must not affect the integrity of the welded steel tube. Markings may be applied using paint, ink, or by other suitable methods, as long as they meet the requirements of the standard. The markings provide critical information for the safe handling, installation, and operation of the welded steel tube, and should be carefully inspected and verified before use.

Standard packing for steel Tubes

Welded steel tube P275NL2, as per EN-10217-3, must be properly packed to protect it from damage during transportation and handling. The following are some standard packing methods for P275NL2 steel tubes:
1. Bundles: Steel tubes are bundled together using steel straps or other suitable materials. The bundles are then wrapped in plastic or other moisture-resistant material to protect them from moisture and other environmental factors.
2. Wooden crates: Steel tubes can be packed in wooden crates for additional protection. The crates are designed to withstand the weight of the steel tubes and provide additional protection against damage during transportation.
3. Pallets: Steel tubes can be packed on wooden or plastic pallets, which provide a stable base for transportation and handling. The pallets are wrapped in plastic or other moisture-resistant material to protect the steel tubes from moisture and other environmental factors.
4. End caps and protectors: Steel tubes are often fitted with end caps and protectors to prevent damage to the ends of the tubes during transportation and handling.
The specific packing method used for P275NL2 steel tubes may vary depending on the size, quantity, and destination of the shipment. It is important to consult with the manufacturer or supplier to ensure that the proper packing method is used to protect the steel tubes during transportation and handling. Proper packing helps to ensure that the P275NL2 steel tubes arrive at their destination in good condition and ready for use.
