A specialized technician uses an eddy current probe that emits a magnetic field, and any disruptions or changes in the field are measured and analyzed to detect any defects or inconsistencies.
4. Radiographic testing: This method uses X-rays or gamma rays to produce images of the welded steel tube, which can be used to detect any internal defects such as cracks, voids, or inclusions. A qualified radiographer takes the radiographic images, and a trained interpreter analyzes them to detect any defects or inconsistencies.
5. Tensile testing: This method is used to measure the mechanical properties of the steel tube, such as its yield strength, tensile strength, and elongation. A specialized machine applies a pulling force to the tube until it fractures, and the force required to break the tube is measured and analyzed to determine its mechanical properties.
Overall, these inspection and testing methods are crucial to ensure that welded steel tubes of grade E155 meet the requirements of EN 10305-3 and are fit for their intended precision applications.

Pressure and Temperature Ratings

EN 10305-3 is a European standard that specifies the technical delivery conditions for welded steel tubes for precision applications. The standard covers various grades of steel tubes, including E155, which is a low-carbon steel grade.
The pressure rating and temperature limit for welded steel tube E155 depend on various factors such as the diameter of the tube, wall thickness, and the intended application. Generally, the pressure rating for the tube is determined based on its yield strength, which is the maximum stress that the tube can withstand before it starts to deform permanently.
For E155 welded steel tube, the yield strength ranges between 140-220 MPa, depending on the heat treatment and other factors. Therefore, the pressure rating for E155 welded steel tube can vary between 140-220 bar (2000-3200 psi) for low-pressure applications, such as fluid transportation, and up to 600 bar (8700 psi) for high-pressure applications, such as hydraulic systems.
The temperature limit for E155 welded steel tube depends on the material properties and the intended application. Generally, low-carbon steel grades like E155 have a good resistance to high temperatures, but their strength and toughness may decrease at elevated temperatures.
For E155 welded steel tube, the recommended temperature limit is between -50°C to 120°C (-58°F to 248°F), depending on the application and the operating conditions. However, the actual temperature limit may vary depending on the tube's material properties, wall thickness, and other factors.
It's important to note that the pressure rating and temperature limit for E155 welded steel tube should be determined based on the applicable standards and codes, as well as the specific application requirements. Therefore, it's essential to consult with a qualified engineer or technical expert to determine the appropriate pressure rating and temperature limit for E155 welded steel tube.
