4. Impact Toughness: The minimum impact toughness of P690QL1 steel tube is 60 J (44 ft-lb) at -40°C (-40°F), which means that the steel can absorb an impact of 60 J without breaking at a temperature of -40°C.

5. Hardness: The maximum hardness of P690QL1 steel tube is 250 HBW, which means that the steel has a moderate level of hardness and can be easily machined and formed.

Overall, Seamless Steel Tube P690QL1, EN 10216-3 is a high-strength steel tube with excellent mechanical properties that make it suitable for high-pressure applications.

Inspection and testings

Seamless Steel Tube P690QL1 is a high-strength, low-alloy, fine-grain steel tube designed for use in pressure vessel and boiler applications. It is manufactured according to the European standard EN 10216-3, which specifies the technical delivery conditions for alloyed and non-alloyed seamless steel tubes for elevated temperatures.
Inspection and testing are critical steps in the manufacturing process of Seamless Steel Tube P690QL1. They ensure that the tube meets the specified requirements and is suitable for its intended use. The following are some of the inspections and tests that may be carried out on Seamless Steel Tube P690QL1:
1. Visual Inspection: This involves a thorough visual examination of the tube to check for any surface defects, such as cracks, pits, scratches, and rust. It is the first step in the inspection process and helps to identify any defects that may affect the quality of the tube.
2. Dimensional Inspection: This involves measuring the diameter, wall thickness, length, and straightness of the tube to ensure that they meet the specified tolerances.
3. Ultrasonic Testing: This is a non-destructive testing method that uses high-frequency sound waves to detect any defects, such as cracks, in the tube. It is a reliable method for detecting defects in the tube's wall thickness and can be carried out on both the inner and outer surfaces of the tube.
4. Charpy Impact Testing: This is a mechanical test that measures the energy absorbed by the tube when it is subjected to a sudden impact. It is a measure of the tube's toughness and resistance to brittle fracture.
5. Tensile Testing: This involves applying a tensile load to the tube until it breaks. It measures the tube's ultimate strength, yield strength, and elongation.
6. Chemical Analysis: This involves analyzing the chemical composition of the tube to ensure that it meets the specified requirements. It checks the levels of various elements, such as carbon, manganese, silicon, sulfur, and phosphorus.
7. Hydrostatic Testing: This involves filling the tube with water and subjecting it to a pressure higher than its working pressure to check for any leaks or defects.
These inspections and tests help to ensure that Seamless Steel Tube P690QL1 meets the specified requirements and is suitable for its intended use in pressure vessel and boiler applications.

Pressure and Temperature Ratings

Seamless steel tubes are commonly used in a variety of applications that require high strength and resistance to pressure and temperature. The P690QL1 steel tube is a seamless steel tube that conforms to the EN 10216-3 standard. The EN 10216-3 standard specifies the technical delivery conditions for alloyed and non-alloyed steel tubes for pressure purposes.
The pressure and temperature ratings for seamless steel tube P690QL1, EN 10216-3 are determined by various factors, including the material properties, the design of the tube, and the operating conditions.
The P690QL1 steel tube has a minimum yield strength of 690 MPa and is designed for use in high-pressure and high-temperature environments. The tube is suitable for use in applications such as steam boilers, pipelines, and pressure vessels.
The pressure rating for the P690QL1 steel tube is determined by its wall thickness and diameter. The tube has a maximum operating pressure of 100 bar (1450 psi) at a temperature of 400°C (752°F) and a minimum operating temperature of -40°C (-40°F). However, the actual pressure rating may vary depending on the specific application and operating conditions.
The temperature rating for the P690QL1 steel tube is determined by its material properties and design. The tube can withstand temperatures up to 400°C (752°F) without undergoing any significant degradation or loss of strength.
