Mechanical properties

Seamless Steel Tube P355NL2 is a high-temperature, high-pressure vessel steel that is designed to be used in demanding environments such as chemical processing plants, oil and gas refineries, and power generation facilities. It is manufactured in accordance with the European standard EN 10216-3.
The mechanical properties of Seamless Steel Tube P355NL2 are critical for its performance in various applications. Here are some of its key mechanical properties:

Steel name: P355NL2

Steel number: 1.0566

1. Tensile strength: The minimum tensile strength of Seamless Steel Tube P355NL2 is 490-630 MPa. This indicates the amount of force the steel can resist before breaking or deforming.

2. Yield strength: The minimum yield strength of Seamless Steel Tube P355NL2 is 355 MPa. This represents the stress level the steel can tolerate without experiencing permanent deformation.

3. Elongation: The minimum elongation of Seamless Steel Tube P355NL2 is 22%. This indicates the amount of stretching the steel can endure before breaking.

4. Impact strength: The minimum impact strength of Seamless Steel Tube P355NL2 is 27J at -50°C. This indicates the amount of energy the steel can absorb without breaking or deforming when subjected to an impact.

5. Hardness: The maximum hardness of Seamless Steel Tube P355NL2 is 220HB. This is a measure of the steel's resistance to deformation, with higher values indicating a tougher and more durable material.

In conclusion, the mechanical properties of Seamless Steel Tube P355NL2 make it a robust and reliable material suitable for use in extreme environments with high pressure and temperature.

Inspection and testings

Seamless steel tube P355NL2 is a type of high-temperature, low-temperature, and pressure-resistant steel tube that is commonly used in various industries, including petrochemical, power generation, and energy production. The EN 10216-3 specification covers technical delivery conditions for seamless tubes of circular cross-sections made of alloy fine grain steel.
To ensure the quality and reliability of P355NL2 steel tubes, various inspection and testing procedures are typically carried out during and after the manufacturing process. These may include:
1. Visual Inspection: This involves a thorough visual examination of the steel tube's surface to check for any defects, such as cracks, pits, or deformities.
2. Dimensional Inspection: This involves measuring the dimensions of the steel tube to ensure it meets the specified size and tolerance requirements.
3. Chemical Composition Analysis: This involves analyzing the chemical composition of the steel tube to ensure it meets the required specifications for elements such as carbon, silicon, manganese, phosphorus, sulfur, and others.
4. Mechanical Properties Testing: This involves testing the mechanical properties of the steel tube, including its tensile strength, yield strength, elongation, and hardness.
5. Non-destructive Testing (NDT): This includes various methods, such as ultrasonic testing, magnetic particle testing, and radiographic testing, to detect internal and surface defects in the steel tube.
6. Hydrostatic Testing: This involves subjecting the steel tube to high-pressure water to test its strength and ability to withstand pressure.
By conducting these inspections and tests, manufacturers can ensure that the P355NL2 steel tubes meet the required specifications and quality standards, thereby providing reliable and safe performance in their intended applications.

Pressure and Temperature Ratings

P355NL2 is a high temperature and pressure grade of seamless steel tube that is manufactured according to the European standard EN 10216-3. The pressure and temperature ratings for this grade of seamless steel tube are as follows:
1. Maximum allowable pressure (in bar) at a temperature of 20°C:
• For tubes with an outside diameter (OD) of up to 60.3mm: 404
• For tubes with an outside diameter (OD) between 60.3mm and 139.7mm: 388
• For tubes with an outside diameter (OD) between 139.7mm and 219.1mm: 359
• For tubes with an outside diameter (OD) between 219.1mm and 323.9mm: 342
• For tubes with an outside diameter (OD) between 323.9mm and 660.4mm: 307
2. Maximum allowable temperature (in °C) at a pressure of 1 bar:
• For tubes with an outside diameter (OD) of up to 60.3mm: 400
• For tubes with an outside diameter (OD) between 60.3mm and 139.7mm: 400
• For tubes with an outside diameter (OD) between 139.7mm and 219.1mm: 400
• For tubes with an outside diameter (OD) between 219.1mm and 323.9mm: 400
• For tubes with an outside diameter (OD) between 323.9mm and 660.4mm: 400
It is important to note that these ratings are based on the specific properties and manufacturing standards of P355NL2 seamless steel tubes, and should not be applied to other grades or types of steel tubes.

Standard marking

P355NL2 is a low-alloy special steel grade for pressure vessel construction, as specified in the European standard EN 10028-3. The EN 10216-3 specification covers seamless steel tubes for pressure purposes, including P355NL2 tubes.
In terms of standard marking, the P355NL2 seamless steel tube would typically be marked with the following information:
• Manufacturer's name or trademark
• Standard designation (e.g. EN 10216-3)
• Steel grade (e.g. P355NL2)
• Dimensions (e.g. outer diameter x wall thickness)
• Heat number or batch identification code
• Additional symbols or markings as required by the standard or the manufacturer
The marking may be applied directly to the tube or to a label or tag attached to the tube. The purpose of the marking is to provide traceability and ensure that the tube meets the required specifications for its intended application.

Standard packing for steel Tubes

Packing for steel tubes is an important aspect of the manufacturing and transportation process to ensure the safety and protection of the product during handling and shipping. The packing standard for steel tubes may vary depending on the industry, product specifications, and transportation requirements.
However, in general, the following are the common packing standards for steel tubes:
1. Bundles: Steel tubes are often packed in bundles. The tubes in a bundle are tightly tied together using steel straps or plastic wrapping to prevent them from coming apart during transportation.
2. Wooden Crates: Steel tubes can also be packed in wooden crates to provide additional protection during transportation. The crates are designed to accommodate the tubes and may be lined with foam or other materials to prevent damage.
3. Plastic Caps: The ends of the steel tubes are typically protected with plastic caps to prevent damage to the ends during transportation.
4. Labels and Markings: The steel tubes are labeled and marked with important information such as product specifications, destination, and handling instructions to ensure proper handling during transportation.
It is important to follow the relevant standards and guidelines for packing steel tubes to ensure the safety and protection of the product during transportation.
