Inspection and testing

Steel square Tube E155, EN-10305-5 is a precision welded steel tube that is designed for use in various applications that require tight dimensional tolerances and high surface quality. To ensure that the tube meets the required specifications and standards, it undergoes a series of inspections and testing procedures during the manufacturing process.
The following are some of the inspection and testing procedures that are carried out on Steel square Tube E155, EN-10305-5:
1. Dimensional Inspection: This involves checking the tube's dimensions such as its outer diameter, inner diameter, and wall thickness, against the specified tolerances. This is usually done using calibrated measuring tools like micrometers, calipers, and gauges.
2. Visual Inspection: This involves examining the surface of the tube for defects such as cracks, scratches, dents, and other surface imperfections. Any surface defects found are recorded and evaluated according to the specified acceptance criteria.
3. Ultrasonic Testing: This involves using ultrasonic waves to detect any defects that are not visible to the naked eye, such as internal cracks and voids. This testing method is non-destructive and is used to ensure the tube's integrity.
4. Eddy Current Testing: This involves using an eddy current probe to detect any surface or near-surface defects in the tube. This testing method is also non-destructive and is used to detect defects like cracks and corrosion.
5. Flattening Test: This involves flattening the tube to a specified percentage of its original diameter to check for any deformation or defects. The tube is then visually inspected for any cracks or other defects.
6. Tensile Testing: This involves testing the tube's strength by pulling it until it breaks. This is done to determine its yield strength, ultimate strength, and elongation. These values are used to ensure that the tube meets the required mechanical properties.
7. Chemical Analysis: This involves analyzing the chemical composition of the tube to ensure that it meets the specified requirements for elements like carbon, manganese, sulfur, and phosphorus.
All the above testing and inspections are usually carried out in accordance with the EN-10305-5 standard, and the results are recorded and documented for traceability purposes. By subjecting the Steel square Tube E155, EN-10305-5 to these rigorous inspection and testing procedures, manufacturers can ensure that the tube meets the required quality standards and can perform effectively in its intended application.

Pressure and Temperature Ratings

E155 is a low carbon steel tube that conforms to the European standard EN-10305-5 for welded and cold-sized steel tubes for precision applications. The steel square tube made from E155 steel is a common choice for various industrial applications due to its good mechanical properties, including high strength, good formability, and excellent weldability.
The pressure rating and temperature limits for a steel square tube made from E155 steel depend on several factors, including the dimensions of the tube, the wall thickness, and the application. The pressure rating is a measure of the maximum pressure the tube can withstand without bursting, and the temperature limit is the maximum temperature at which the tube can be used without compromising its structural integrity.
According to EN-10305-5 standard, the steel square tube made from E155 steel has a maximum pressure rating of 400 bar and a maximum temperature limit of 120°C. However, these values can vary depending on the size and wall thickness of the tube.
For example, a steel square tube with a wall thickness of 1 mm and a side length of 20 mm can have a pressure rating of approximately 120 bar, while a tube with a wall thickness of 3 mm and a side length of 50 mm can have a pressure rating of approximately 280 bar. Similarly, the temperature limit for a steel square tube can be influenced by factors such as the type of fluid or gas flowing through the tube, the duration of exposure to high temperatures, and the presence of any external factors that can affect the tube's structural integrity.
In summary, the pressure rating and temperature limits for a steel square tube made from E155 steel can vary depending on the size, wall thickness, and application. It is important to consult the manufacturer's specifications and guidelines to ensure the tube is used within its recommended pressure and temperature limits for optimal performance and safety.
