Mechanical properties
Seamless Steel Tube P620QH is a high-temperature and high-pressure steel tube that conforms to the European standard EN 10216-3. It is designed for use in pressure vessel and boiler applications where elevated temperatures and pressures are present.
The mechanical properties of Seamless Steel Tube P620QH are as follows:

 
Steel name: P620QH Steel number: 1.8877 • Tensile strength: The minimum tensile strength of the tube is 690 MPa (megapascals).
• Yield strength: The minimum yield strength of the tube is 620 MPa.
• Elongation: The minimum elongation of the tube after fracture is 17%.
• Impact strength: The minimum impact strength of the tube is 27 J (joules) at a temperature of -20°C (-4°F).
• Hardness: The maximum hardness of the tube is 248 HB (Brinell hardness).
These mechanical properties ensure that Seamless Steel Tube P620QH can withstand high pressures and temperatures without deformation or failure. It is an ideal choice for use in pressure vessels, boilers, and other high-temperature and high-pressure applications.
 Inspection and testings 
The inspection and testing of Seamless Steel Tube P620QH, EN 10216-3, are critical to ensuring that the tube meets the required quality and performance standards. The following are some of the inspection and testing methods that may be employed:
1. Visual inspection: This involves a visual examination of the tube's surface to check for any cracks, corrosion, or other defects.
2. Dimensional inspection: This is done to ensure that the tube meets the required dimensions and tolerances.

3. Ultrasonic testing: This method uses high-frequency sound waves to detect any internal defects or flaws in the tube, such as cracks or voids.
4. Hydrostatic testing: This involves filling the tube with water and subjecting it to a specified pressure to check for leaks or other defects.
5. Tensile testing: This method measures the tube's tensile strength and yield strength to ensure that they meet the required standards.
6. Hardness testing: This involves measuring the tube's hardness using a hardness testing machine to ensure that it meets the required hardness specifications.
7. Charpy V-notch impact testing: This method measures the tube's impact strength at a specified temperature to ensure that it can withstand the required level of impact.
By employing these inspection and testing methods, manufacturers can ensure that Seamless Steel Tube P620QH, EN 10216-3, meets the required quality and performance standards and is suitable for use in high-pressure and high-temperature applications.
Pressure and Temperature Ratings
P620QH is a grade of seamless steel tube specified in EN 10216-3, which is a European standard for pressure equipment. The pressure and temperature ratings for this tube depend on various factors such as the wall thickness, diameter, and material properties.
The maximum allowable working pressure (MAWP) for P620QH seamless steel tube is determined by its minimum wall thickness and maximum outside diameter, and it can be calculated using the following formula:
MAWP = (S * t) / D
where S is the minimum yield strength of the material at room temperature, t is the minimum wall thickness of the tube, and D is the maximum outside diameter of the tube.
The maximum allowable working temperature (MAWT) for P620QH seamless steel tube depends on the material properties and the design conditions of the application. The maximum operating temperature for P620QH is 400°C.
It is important to note that the pressure and temperature ratings for seamless steel tube P620QH, EN 10216-3, are intended for design purposes only, and they should not be used as a basis for selecting or sizing the tube for a particular application. The selection of the appropriate tube for a specific application should be based on a thorough analysis of the design requirements, including the pressure, temperature, and other operating conditions.
Standard marking 
P620QH is a high-strength fine-grain steel that is suitable for use in pressure vessels and boilers. EN 10216-3 is a European standard for seamless steel tubes that are used for pressure purposes.
The standard marking of seamless steel tubes typically includes the following information:
1. The name or logo of the manufacturer
2. The dimensions of the tube, including its outer diameter, wall thickness, and length
3. The material grade, which in this case is P620QH
4. The standard number, which in this case is EN 10216-3
5. The heat number or code, which identifies the specific batch of steel used in the tube's production
6. The inspection and testing details, which verify that the tube meets the required standards and specifications.
The exact format and placement of these markings may vary depending on the specific requirements of the manufacturer and the standard being used.
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.
