Pressure and Temperature Ratings

Welded steel tube E190 is a product specified in the European standard EN 10305-3, which covers the technical requirements for seamless and welded cold-drawn precision steel tubes for mechanical applications. The pressure and temperature ratings of welded steel tube E190 are determined by various factors such as its wall thickness, diameter, material, and intended application.
EN 10305-3 does not provide explicit pressure and temperature ratings for welded steel tube E190. However, pressure and temperature ratings can be determined based on the tube's material properties and design specifications.
The pressure rating of welded steel tube E190 can be determined by calculating its allowable stress based on its tensile strength, yield strength, and wall thickness. The temperature rating can be determined by considering the tube's material properties and the intended operating temperature.
It's important to note that pressure and temperature ratings are critical design parameters that should be determined by a qualified engineer, taking into account the specific application and environmental conditions in which the tube will be used.
In summary, while EN 10305-3 does not provide specific pressure and temperature ratings for welded steel tube E190, they can be determined based on the tube's material properties, design specifications, and operating conditions. It is recommended to consult with a qualified engineer to determine the appropriate pressure and temperature ratings for a given application.

Surface Treatment

Welded steel tube E190 is a product specified in the European standard EN 10305-3, which covers the technical requirements for seamless and welded cold-drawn precision steel tubes for mechanical applications. The surface treatment of welded steel tube E190 is an important aspect of its manufacturing process as it can affect its properties, appearance, and durability. Here are some common surface treatments specified in EN 10305-3:
1. Phosphating: A thin layer of zinc or manganese phosphate coating is applied to the surface of the tube to enhance its corrosion resistance and improve its paint adhesion.
2. Oiling: A thin layer of oil is applied to the surface of the tube to protect it from rust and improve its appearance.
3. Galvanizing: The tube is dipped in a bath of molten zinc to create a zinc coating that provides excellent corrosion resistance.
4. Painting: The tube can be painted with a variety of coatings to improve its appearance and protect it from corrosion and environmental factors.
5. Powder coating: The tube is coated with a layer of thermoset or thermoplastic powder, which is then cured under heat to create a durable and long-lasting finish.
The choice of surface treatment depends on the intended application of the welded steel tube E190. For example, if the tube is used in corrosive environments, a zinc or manganese phosphate coating may be applied. If the tube is used in applications that require a high-quality appearance, powder coating or painting may be used. It's important to note that surface treatment can add additional cost to the manufacturing process, so the choice of treatment should be carefully evaluated based on the specific needs of the application.

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.
