Inspection and testing

The inspection and testing of Stainless Steel Tube X2CrNiMo18-15-4, EN-10217-7, follows strict procedures to ensure that the tubes meet the required standards and specifications. The following are the common inspection and testing methods used:
1. Visual Inspection: This involves a careful examination of the tube surface, both inside and outside, to ensure that there are no cracks, scratches, or other surface defects.
2. Dimensional Inspection: The dimensions of the tube, including its diameter, wall thickness, and length, are measured to ensure that they meet the required tolerances.
3. Hydrostatic Testing: This is a test where the tube is filled with water and pressurized to a certain level. The pressure is held for a specified period while the tube is checked for leaks or other defects. This test is used to ensure that the tube can withstand the required pressure and is suitable for its intended application.
4. PMI Testing: Positive Material Identification (PMI) is a test that is used to identify the material used to manufacture the tube. It is a non-destructive test that involves using a portable X-ray fluorescence (XRF) analyzer to determine the chemical composition of the material.
5. Ultrasonic Testing: This is a non-destructive test that uses high-frequency sound waves to detect any internal defects in the tube, such as cracks or voids. This test is used to ensure that the tube is free from any defects that could compromise its integrity.
6. Eddy Current Testing: This is another non-destructive test that uses electromagnetic induction to detect surface and near-surface defects in the tube. It is commonly used to detect defects such as cracks, corrosion, or other irregularities in the tube's surface.
7. Intergranular Corrosion Testing: This test is performed to determine the susceptibility of the tube to intergranular corrosion. It involves subjecting the tube to a specific environment and observing its behavior. This test is essential because intergranular corrosion can significantly affect the tube's mechanical properties.
By following these inspection and testing procedures, TAP Viet nam International Investment Joint Stock Company ensures that the Stainless Steel Tube X2CrNiMo18-15-4, EN-10217-7, meet the required standards and specifications and are suitable for their intended applications.

Pressure and Temperature Ratings

The pressure and temperature ratings of Stainless Steel Tube X2CrNiMo18-15-4 according to EN-10217-7 are dependent on several factors, including the tube dimensions, wall thickness, and material properties. The following information provides a general overview of the pressure and temperature ratings for this type of tube:
1. Pressure Ratings: The pressure rating of a tube is determined by the maximum allowable working pressure (MAWP), which is the maximum pressure at which the tube can operate safely. The MAWP is based on the tube dimensions, wall thickness, and material properties. The pressure rating for Stainless Steel Tube X2CrNiMo18-15-4 is typically calculated based on the following formula:
MAWP = 2 SE t / D
Where:
• MAWP is the maximum allowable working pressure in MPa
• SE is the stress value for the material at the operating temperature, which can be obtained from material standards
• t is the wall thickness of the tube in mm
• D is the outside diameter of the tube in mm
2. Temperature Ratings: The temperature rating of a tube is determined by the maximum allowable operating temperature (MAOT), which is the maximum temperature at which the tube can operate safely. The MAOT is based on the material properties and is typically determined based on the following formula:
MAOT = (0.6 * TS) / SA
Where:
• MAOT is the maximum allowable operating temperature in degrees Celsius
• TS is the maximum service temperature of the material in degrees Celsius
• SA is the allowable stress value for the material at the MAOT, which can be obtained from material standards
It is important to note that the pressure and temperature ratings for Stainless Steel Tube X2CrNiMo18-15-4 may vary depending on the specific application and operating conditions. Therefore, it is recommended to consult with a qualified engineer or refer to the appropriate material standards for detailed information on pressure and temperature ratings.

Standard marking for steel tubes

According to EN-10217-7, Stainless Steel Tube X2CrNiMo18-15-4 must be marked with the following information:
1. Manufacturer's name or trademark
2. Steel grade, for example, X2CrNiMo18-15-4
3. Dimensions, such as outer diameter (OD), wall thickness (WT), and length
4. Heat number, which identifies the heat treatment batch and allows for traceability
5. Inspection symbol, such as EN 10204 3.1, which indicates the type of inspection and the corresponding test report
6. Pressure rating, if applicable
7. CE marking, which indicates compliance with EU regulations
The marking can be done by painting, stamping, or by other suitable methods that ensure durability and legibility. The marking must be clear and indelible and located on a visible and accessible surface of the tube.
