It is a product that meets the requirements of the EN 10216-3 standard, which specifies the technical delivery conditions for alloyed fine-grain steel tubes for pressure purposes.
The mechanical properties of Seamless Steel Tube P690QL2, as specified in EN 10216-3, are as follows:

Steel name: P690QL2

Steel number: 1.8888

1. Tensile strength: The minimum tensile strength of P690QL2 seamless steel tube is 770 MPa (MegaPascals), and the maximum tensile strength is 940 MPa.

2. Yield strength: The minimum yield strength of P690QL2 seamless steel tube is 690 MPa, and the maximum yield strength is 900 MPa.

3. Elongation: The minimum elongation after fracture for P690QL2 seamless steel tube is 14%, measured on a gauge length of 5.65√S0 (where S0 is the initial cross-sectional area of the gauge length).

4. Impact strength: The minimum impact energy at a temperature of -60°C for P690QL2 seamless steel tube is 27 J (Joules).

In addition to these mechanical properties, Seamless Steel Tube P690QL2 also exhibits good weldability and formability. It is suitable for use in a variety of applications, including pressure vessels, pipelines, and boilers, where high strength and resistance to creep and fatigue are required.

Inspection and testings

The inspection and testing of Seamless Steel Tube P690QL2, as per the requirements of EN 10216-3 standard, include the following:
1. Chemical Composition Analysis: The chemical composition of the steel used to manufacture the seamless tube is verified to ensure that it meets the specified requirements of EN 10216-3. The chemical composition analysis is typically conducted using techniques such as optical emission spectroscopy (OES) or X-ray fluorescence (XRF).
2. Mechanical Properties Testing: The mechanical properties of the seamless tube, including tensile strength, yield strength, elongation, and impact strength, are tested to ensure they meet the requirements of EN 10216-3.
3. Non-Destructive Testing (NDT): Various non-destructive testing techniques are used to detect any defects or anomalies in the seamless tube. These techniques include ultrasonic testing (UT), eddy current testing (ECT), magnetic particle testing (MPT), and dye penetrant testing (DPT).
4. Dimensional Inspection: The dimensions of the seamless tube, including its outer diameter, wall thickness, and length, are inspected to ensure they meet the specified requirements of EN 10216-3.
5. Visual Inspection: The surface of the seamless tube is inspected visually to detect any defects or surface irregularities such as cracks, porosity, or corrosion.
6. Hydrostatic Testing: A hydrostatic test is conducted to verify the strength and integrity of the seamless tube under pressure. The tube is filled with water and pressurized to a specified level, and then the pressure is held for a specified duration. Any leaks or failures are detected during this test.
7. Heat Treatment Verification: If the seamless tube is subjected to any heat treatment, such as normalization or quenching and tempering, the heat treatment process is verified to ensure that it has been carried out according to the specified requirements of EN 10216-3.
All these inspections and testing are essential to ensure the quality, safety, and reliability of the Seamless Steel Tube P690QL2, and to ensure that it meets the requirements of the EN 10216-3 standard.

Pressure and Temperature Ratings

EN 10216-3 is a European standard for seamless steel tubes used in pressure applications. P690QL2 is a high-strength, fine-grained steel grade with a minimum yield strength of 690 MPa. The pressure and temperature ratings for seamless steel tube P690QL2, as per EN 10216-3, are as follows:
Maximum allowable pressure (in bar) at various temperatures (in °C):
• 100°C: 260 bar
• 200°C: 250 bar
• 300°C: 235 bar
• 400°C: 215 bar
• 450°C: 205 bar
• 500°C: 195 bar
These pressure ratings are based on the maximum allowable stress values for P690QL2 at different temperatures and are intended for use in applications where the tube is subjected to internal pressure.
It is important to note that these pressure ratings are for seamless steel tubes only and may vary depending on factors such as tube diameter, wall thickness, and length. Additionally, the maximum temperature and pressure ratings should not be exceeded in order to avoid tube failure and ensure safety.

Standard marking

The standard marking of steel tubes is an important aspect of identifying the characteristics and properties of the tube. The marking provides information such as the material, dimensions, and manufacturing standards. Here is an example of standard marking for seamless steel tube P690QL2, EN 10216-3:
• "P690QL2" indicates the material grade of the steel tube. In this case, it refers to a high-strength quenched and tempered steel.
• "EN 10216-3" indicates the European standard for seamless steel tubes for pressure purposes. EN 10216-3 specifies technical delivery conditions for alloy fine grain steel tubes.
• Other markings that may appear on the tube include the manufacturer's name or trademark, the production batch number, and the heat number.
Overall, the standard marking provides crucial information for proper identification, quality control, and traceability of the steel tube.

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.
