Mechanical properties

Seamless Steel Tube P235TR1 is a carbon-manganese steel grade that is used in the production of pressure vessels, boilers, and heat exchangers. It is designed to operate under high-pressure and high-temperature conditions and is suitable for use in a variety of industrial applications.
The mechanical properties of Seamless Steel Tube P235TR1 are specified by the European standard EN 10216-1. The following are the typical mechanical properties of this steel grade:

Steel name: P235TR1

Steel number: 1.0254

• Yield strength: 235 MPa (34 ksi)

• Tensile strength: 360-500 MPa (52-72 ksi)

• Elongation: 25%

• Impact strength: Notched impact strength of 27 J (20 ft-lbf) at a temperature of 20°C (68°F)

These properties are measured on the basis of a sample that has been normalized or normalized and tempered. The normalization process involves heating the steel to a temperature above the transformation range and then cooling it in air to obtain a homogeneous microstructure. Tempering involves heating the normalized steel to a temperature below the transformation range and holding it at that temperature for a specified period before cooling it in air.
In addition to these mechanical properties, Seamless Steel Tube P235TR1 is also characterized by its chemical composition, which includes carbon, manganese, silicon, phosphorus, sulfur, and other elements in trace amounts. The composition of this steel grade is also specified by the EN 10216-1 standard.

Inspection and testings

Seamless steel tube P235TR1, EN 10216-1 is a European standard for seamless steel tubes used for pressure purposes. The tube is made of non-alloy steel and has a minimum yield strength of 235 N/mm².
Inspection and testing of seamless steel tube P235TR1, EN 10216-1 typically involve the following procedures:
1. Visual inspection: This involves checking the surface of the tube for any defects such as cracks, dents, and scratches.
2. Dimensional inspection: The dimensions of the tube are measured to ensure that they meet the specified tolerances.
3. Chemical analysis: The chemical composition of the steel used to make the tube is analyzed to ensure that it meets the specified requirements.
4. Mechanical testing: This involves testing the tube's mechanical properties, such as tensile strength, yield strength, and elongation.
5. Non-destructive testing: Various non-destructive testing methods, such as ultrasonic testing, magnetic particle testing, and radiographic testing, may be used to detect any internal defects in the tube.
6. Hydrostatic testing: The tube is filled with water and pressurized to a specified level to check its resistance to internal pressure.
7. Surface condition testing: This involves checking the tube's surface for any defects, such as pits or cracks, using various methods such as eddy current testing or dye penetrant testing.
Overall, inspection and testing of seamless steel tube P235TR1, EN 10216-1 are crucial to ensure its suitability for use in high-pressure applications.

Pressure and Temperature Ratings

Seamless steel tubes of grade P235TR1, as per EN 10216-1 standard, are designed for use in pressure applications, particularly for conveying fluids in industries such as petroleum, gas, and chemical processing.
The pressure rating of P235TR1 seamless steel tubes depends on their size, wall thickness, and operating temperature. In general, the higher the wall thickness and operating temperature, the lower the pressure rating.
According to the EN 10216-1 standard, the maximum allowable pressure for P235TR1 seamless steel tubes at various temperatures is as follows:
• For temperatures up to 300°C: 25 bar
• For temperatures up to 400°C: 23.5 bar
• For temperatures up to 500°C: 20.8 bar
• For temperatures up to 600°C: 17.5 bar
• For temperatures up to 700°C: 14.2 bar
Similarly, the temperature rating of P235TR1 seamless steel tubes is determined by their size and wall thickness, as well as the maximum allowable operating pressure. The maximum allowable temperature for P235TR1 seamless steel tubes at various pressure levels is as follows:
• For pressures up to 20 bar: 300°C
• For pressures up to 19.5 bar: 400°C
• For pressures up to 17.3 bar: 500°C
• For pressures up to 14.5 bar: 600°C
• For pressures up to 11.7 bar: 700°C
It is important to note that the above ratings are based on the use of P235TR1 seamless steel tubes in accordance with EN 10216-1 standard and proper installation, operation, and maintenance. Deviations from these conditions can affect the performance and safety of the tubes, and should be avoided.

Standard marking

The standard marking of a seamless steel tube P235TR1 according to EN 10216-1 includes the following information:
1. Manufacturer's name or trademark
2. Tube size (outside diameter and wall thickness)
3. Steel grade designation (P235TR1)
4. Heat number or cast number for traceability
5. EN 10216-1 standard designation
6. Inspection symbol (usually "TÜV" or "DNV" for third-party inspection)
7. Batch number or production code
8. Country of origin
9. Additional markings as required by the purchaser or relevant regulations.
The marking is usually stamped or painted on the surface of the tube at regular intervals, typically every meter or every five tubes. This information helps to identify the origin and quality of the tube, and to ensure that it meets the requirements of the relevant standard.

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.
