The maximum allowable content of each element is specified in the EN-10217-3 standard to ensure the proper properties of the steel for pressure vessel applications. The above composition provides good weldability and toughness, which are important properties for steel tubes used in high-pressure and high-temperature applications.

Mechanical Properties

The mechanical properties of Welded Steel Tube P355NL1 as per EN-10217-3 standard, are as follows:

Steel name: P355NL1

Steel number: 1.0566

Tensile strength: 490-630 N/mm²

Yield strength: 355 N/mm²

Elongation: 22%

Impact strength: -50°C, minimum 27 Joules

These properties are tested and specified in accordance with the EN-10217-3 standard. The yield strength of 355 MPa indicates the minimum amount of stress that the steel can withstand before permanent deformation occurs. The tensile strength of 490-630 MPa refers to the maximum amount of stress that the steel can withstand before breaking. The elongation of 22% means that the steel can stretch up to 22% of its original length before breaking.
The impact strength (Charpy V-notch) is a measure of the energy absorbed by the steel when subjected to an impact. The minimum impact strength of 27 Joules at a temperature of -50°C ensures that the steel can withstand low-temperature applications without fracturing. These mechanical properties make P355NL1 a suitable material for manufacturing welded steel tubes for use in pressure vessels, boilers, and pipelines that operate under high-pressure and high-temperature conditions.

Inspection and testing

The inspection and testing of welded steel tube P355NL1, EN-10217-3, are crucial to ensuring that the tube meets the required quality standards and specifications. The following inspections and tests are typically carried out on welded steel tube P355NL1:
1. Visual inspection: This is carried out to check for surface defects such as cracks, porosity, and other irregularities.
2. Dimensional inspection: This is to check the tube's size, wall thickness, and ovality.
3. Non-destructive testing: This involves testing the welded tube using techniques such as ultrasonic testing, radiography, or magnetic particle inspection to detect any internal defects.
4. Mechanical testing: This involves testing the mechanical properties of the steel tube such as tensile strength, yield strength, elongation, and impact strength.
5. Chemical analysis: This is to confirm that the chemical composition of the steel tube meets the required standards.
6. Hydrostatic testing: This is to check the tube's resistance to internal pressure by filling it with water and subjecting it to a specified pressure.
7. Flattening testing: This involves flattening the tube to a specified percentage of its original diameter to ensure that it does not crack or fracture.
These inspections and tests are carried out in accordance with the EN-10217-3 standard and any applicable customer or regulatory requirements. The test reports and certificates are usually provided to the customer as evidence of the quality of the welded steel tube.

Pressure and Temperature Ratings of

The pressure and temperature ratings of welded steel tube P355NL1, EN-10217-3, are determined by the material's mechanical properties and the operating conditions of the application. The maximum allowable pressure and temperature for P355NL1 steel tubes are specified in the EN-10217-3 standard and may vary depending on the diameter and wall thickness of the tube.
The pressure and temperature ratings for welded steel tube P355NL1 are typically determined using the ASME Boiler and Pressure Vessel Code (BPVC) or equivalent standards. The following are some general guidelines for the pressure and temperature ratings of P355NL1 steel tubes:
• Maximum allowable pressure: The maximum allowable pressure for P355NL1 steel tubes typically ranges from 20 to 100 bar, depending on the diameter and wall thickness of the tube.
• Maximum allowable temperature: The maximum allowable temperature for P355NL1 steel tubes depends on the pressure and the thickness of the tube. For example, at a pressure of 20 bar, the maximum allowable temperature for a tube with a thickness of 10 mm is approximately 400°C.
It is important to note that the pressure and temperature ratings may vary depending on the specific application and the operating conditions. It is essential to consult with the manufacturer or an engineering professional to determine the appropriate pressure and temperature ratings for a given application.

Standard marking for welded steel tubes

6. Production date: The date of manufacture of the tube.
7. Inspection and testing information: The mark should indicate which inspection and testing standards were used to test the tube, and the results of the tests performed.
8. Additional information: Any additional information that is relevant to the tube's application or use, such as the maximum allowable pressure and temperature.
The marking is typically applied by means of stenciling, engraving, or printing, and must be legible and durable. This information allows the tube to be easily identified and traced back to its origin in case of any issues or defects.

Standard packing for steel Tubes

The standard packing for Welded Steel Tube P355NL1, EN-10217-3, usually depends on the diameter and length of the tube. Generally, the tube is protected against mechanical damage and corrosion during transportation and storage.
Here are some common standard packing methods for welded steel tube P355NL1:
1. Bundles: The tubes are bundled together using steel straps or ropes. The bundle is then wrapped in a plastic sheet to protect it from moisture and corrosion. The bundle is marked with the necessary information, such as the size, grade, and batch number.
2. Wooden boxes: Tubes are packed in wooden boxes to provide additional protection against damage. The box is usually lined with a moisture-resistant material and filled with packing material to prevent the tubes from moving during transportation.
3. Steel crates: Steel crates are used to pack heavy and large-diameter tubes. The crate is lined with a moisture-resistant material and filled with packing material to prevent the tubes from moving during transportation.
4. Plastic caps and plugs: The ends of the tubes are capped with plastic caps or plugs to protect them from damage during transportation and storage.
The standard packing is usually in accordance with customer requirements and applicable regulations. The packing is intended to ensure that the tube arrives at its destination without any damage and is ready for immediate use.
