Pressure and Temperature Ratings

The pressure rating and temperature limits for Welded Steel Tube E220, EN 10305-3 depend on several factors, including the tube's size, wall thickness, and intended application. The pressure rating and temperature limits are important considerations because exceeding these limits can result in tube failure and potentially hazardous situations.
The pressure rating for Welded Steel Tube E220 is typically calculated using the Barlow's formula, which takes into account the tube's dimensions and material properties. For example, a Welded Steel Tube E220 with an outer diameter of 50 mm and a wall thickness of 2 mm can withstand a maximum pressure of approximately 107 bar (1550 psi) at room temperature (20°C). However, the pressure rating decreases as the temperature increases due to the reduction in material strength.
The temperature limit for Welded Steel Tube E220 is also dependent on the tube's intended application and the materials used in its construction. In general, the tube's maximum temperature limit is determined by its material properties and its ability to maintain its strength and structural integrity at high temperatures. For Welded Steel Tube E220, the maximum temperature limit is typically around 400°C (752°F) when used in applications that require high-temperature resistance.
It is essential to follow the manufacturer's recommendations for pressure and temperature limits when using Welded Steel Tube E220 to ensure safe and reliable operation. It is also important to consider the tube's intended application and environmental conditions when determining the appropriate pressure and temperature limits. Proper installation, maintenance, and inspection of the tube can help prevent failure and ensure safe operation.

Sizes and diameter tolerances Welded cold sized Steel tubes EN 10305-3 EN 10305-3 is a European standard that specifies the technical delivery conditions for welded cold-sized steel tubes for precision applications. These tubes are typically used in the mechanical engineering and automotive industries, where high precision and reliability are required. The standard defines several requirements for the sizes and diameter tolerances of the tubes. These include: 1. Nominal sizes: The nominal sizes of the tubes range from 6mm to 200mm, with wall thicknesses from 0.5mm to 10mm. 2. Dimensions: The standard specifies the dimensions of the tubes, including the outside diameter, wall thickness, and length. The outside diameter of the tubes ranges from 6mm to 200mm, with a tolerance of +/- 0.08mm. The wall thickness ranges from 0.5mm to 10mm, with a tolerance of +/- 10%. 3. Ovality: The standard specifies the ovality of the tubes, which is the difference between the maximum and minimum diameter of the tube divided by the nominal diameter. The ovality tolerance ranges from 0.4% to 1.0%, depending on the diameter and wall thickness of the tube. 4. Straightness: The standard specifies the straightness of the tubes, which is the maximum deviation from a straight line over the length of the tube. The straightness tolerance ranges from 0.15% to 0.25% depending on the diameter and wall thickness of the tube. 5. Length: The standard specifies the length of the tubes, which can be cut to specific lengths or supplied in random lengths. The tolerance on length is +/- 500mm or +/- 3% of the total length, whichever is greater. 6. Surface finish: The standard specifies the surface finish of the tubes, which must be free from defects and have a smooth, clean surface. In summary, the EN 10305-3 standard defines the sizes and diameter tolerances for welded cold-sized steel tubes for precision applications, including nominal sizes, dimensions, ovality, straightness, length, and surface finish. These specifications ensure that the tubes meet the high precision and reliability requirements of the mechanical engineering and automotive industries.
