 Inspection and testing 
Inspection and testing are important processes in the manufacturing of Welded Steel Tube E195, EN 10305-6 to ensure that the tubes meet the required specifications and are suitable for their intended applications. The following are some of the common inspection and testing methods used for this type of steel tube:
1. Visual Inspection: This is the first step in the inspection process, where the tubes are visually inspected to ensure they are free from any surface defects such as cracks, scratches, and dents.
2. Dimensional Inspection: This involves measuring the dimensions of the tubes to ensure they meet the specified requirements in terms of length, diameter, and wall thickness.
3. Chemical Composition Analysis: This test determines the chemical composition of the tube and ensures that the alloy composition is consistent with the required specifications.
4. Mechanical Testing: The mechanical properties of the tube are determined by conducting various tests such as tensile testing, yield strength testing, and elongation testing. These tests measure the tube's ability to withstand stress and strain under various conditions.
5. Non-destructive Testing: This includes various testing methods such as ultrasonic testing, magnetic particle testing, and liquid penetrant testing. These methods are used to detect any internal or surface defects that may affect the performance of the tube.
6. Pressure Testing: Pressure testing is carried out to ensure that the tube can withstand the specified pressure without leaking or bursting.
All the inspection and testing processes are carried out in accordance with the relevant standards and specifications, such as EN 10204, which specifies the types of inspection documents that should be provided to customers to ensure that the tubes meet the required standards. These documents include test reports, material certificates, and inspection certificates.
Pressure and Temperature Ratings
The pressure rating and temperature range of Welded Steel Tube E195, EN 10305-6 depend on various factors such as the tube dimensions, wall thickness, and the intended application. However, in general, the pressure rating and temperature range of this type of steel tube can be determined based on the following considerations:
1. Pressure Rating: The pressure rating of Welded Steel Tube E195, EN 10305-6 depends on the wall thickness and diameter of the tube. The higher the wall thickness and diameter, the higher the pressure rating. The pressure rating is typically determined using the Barlow's formula, which takes into account the tensile strength and wall thickness of the tube. The maximum pressure rating for this type of tube is typically around 400 bar.
2. Temperature Range: The temperature range of Welded Steel Tube E195, EN 10305-6 depends on the materials used to manufacture the tube and the intended application. The temperature range can vary from -20°C to 120°C, but this may vary based on the specific application and environment. It is important to note that at higher temperatures, the tube may experience reduced strength and increased risk of deformation or failure.
It is essential to follow the recommended pressure rating and temperature range for Welded Steel Tube E195, EN 10305-6 to ensure its safe and effective use in various applications. The pressure rating and temperature range should be evaluated based on the specific application and environment to ensure that the tube can withstand the expected operating conditions without compromising safety and performance.

 
Surface Treatment
The surface treatment of Welded Steel Tube E195, EN 10305-6 is an important step in the manufacturing process that can improve the appearance, durability, and corrosion resistance of the tube. There are several surface treatment options available for this type of steel tube, including:
1. Phosphating: This is a chemical treatment that involves immersing the tube in a solution of phosphoric acid and zinc or manganese salts. The treatment creates a phosphate coating on the surface of the tube that improves corrosion resistance and provides a base for further surface treatments.
2. Galvanizing: This is a process where the tube is coated with a layer of zinc to provide protection against corrosion. The galvanizing process involves immersing the tube in a bath of molten zinc, which adheres to the surface of the tube to create a protective layer.
3. Painting: Painting is a surface treatment option that involves applying a layer of paint to the surface of the tube. This can improve the appearance of the tube and provide some level of corrosion resistance.
4. Electroplating: This is a process where a metal coating is deposited onto the surface of the tube through an electrochemical process. The metal coating can provide corrosion resistance and improve the appearance of the tube.
The choice of surface treatment will depend on the intended application of the Welded Steel Tube E195, EN 10305-6. For example, if the tube is used in a corrosive environment, a treatment like galvanizing or phosphating may be necessary to protect the surface of the tube from corrosion. On the other hand, if appearance is important, painting or electroplating may be the preferred option. It is important to ensure that the chosen surface treatment is compatible with the intended use of the tube to ensure its effectiveness and longevity.

Dimensions and tolerances. Welded cold drawn Steel tubes EN 10305-6
EN 10305-6 is a European standard that specifies the technical delivery conditions for welded cold drawn steel tubes for precision applications. This standard applies to round, square, rectangular, and special shape welded tubes made from unalloyed or low alloy steels.
The standard defines the dimensions and tolerances for these welded cold drawn steel tubes. These include:
1. Outer Diameter (OD): The outer diameter of the tube is measured from the outside edge to the opposite outside edge. The tolerances for OD are specified in the standard, and they depend on the size of the tube. For example, for tubes with an OD of up to 30mm, the tolerance is +/- 0.08mm. For tubes with an OD between 30mm and 50mm, the tolerance is +/- 0.1mm.
2. Inner Diameter (ID): The inner diameter of the tube is measured from the inside edge to the opposite inside edge. The tolerances for ID are also specified in the standard and depend on the size of the tube. For example, for tubes with an OD of up to 30mm, the tolerance is +/- 0.05mm. For tubes with an OD between 30mm and 50mm, the tolerance is +/- 0.07mm.
3. Wall Thickness: The wall thickness of the tube is measured as the distance between the inside and outside surfaces of the tube. The tolerances for wall thickness are specified in the standard and depend on the size of the tube. For example, for tubes with an OD of up to 30mm, the tolerance is +/- 10% of the wall thickness. For tubes with an OD between 30mm and 50mm, the tolerance is +/- 8% of the wall thickness.
4. Ovality: The ovality of the tube is the difference between the maximum and minimum diameters of the tube divided by the nominal diameter. The tolerances for ovality are specified in the standard and depend on the size of the tube. For example, for tubes with an OD of up to 30mm, the maximum ovality tolerance is 0.5% of the OD. For tubes with an OD between 30mm and 50mm, the maximum ovality tolerance is 0.6% of the OD.
5. Straightness: The straightness of the tube is measured as the maximum deviation from a straight line over a specified length. The tolerances for straightness are specified in the standard and depend on the size of the tube. For example, for tubes with an OD of up to 30mm, the maximum deviation tolerance is 0.3mm per meter. For tubes with an OD between 30mm and 50mm, the maximum deviation tolerance is 0.5mm per meter.
6. Length: The length of the tube is specified in the standard and can vary depending on the application. The standard specifies that the length tolerance for tubes up to 7 meters long is +/- 10mm. For tubes longer than 7 meters, the length tolerance is +/- 0.15% of the length.
Overall, these dimensions and tolerances ensure that the welded cold drawn steel tubes meet the required specifications for precision applications.
