Pressure and Temperature Ratings

The pressure and temperature ratings for X1NiMoCuN25-20-7 stainless steel tube are determined by the EN-10217-7 standard. These ratings are based on the maximum allowable working pressure (MAWP) and the maximum allowable working temperature (MAWT) for the tube.
The MAWP for X1NiMoCuN25-20-7 stainless steel tube is determined by several factors, including the dimensions of the tube, the material properties, and the design pressure rating. The MAWP is typically calculated using the Barlow's formula, which takes into account the wall thickness, outside diameter, and allowable stress of the material.
The MAWT for X1NiMoCuN25-20-7 stainless steel tube is also determined by several factors, including the material properties, the design temperature, and the operating conditions. The MAWT is typically determined based on the maximum temperature that the tube can withstand without experiencing any permanent deformation or failure.
The pressure and temperature ratings for X1NiMoCuN25-20-7 stainless steel tube are typically provided by the manufacturer or supplier, and are based on the applicable standards and specifications. It is important to ensure that the tube is operated within its rated pressure and temperature range to ensure safe and reliable operation.

Standard marking for steel tubes

X1NiMoCuN25-20-7 stainless steel tubes are typically marked according to the requirements of the EN-10217-7 standard, which specifies the information that should be included on the tube surface.
The standard marking for X1NiMoCuN25-20-7 stainless steel tubes typically includes the following information:
1. Manufacturer's name or trademark
2. Tube size, including the nominal diameter and wall thickness
3. Steel grade designation (X1NiMoCuN25-20-7)
4. Manufacturing process (welded)
5. EN-10217-7 standard designation
6. Heat number or identification code for traceability
7. Batch number
8. Pressure and temperature ratings
9. Country of origin
The marking is typically applied to the tube surface using a permanent method, such as stamping or engraving. This information is important for identification and traceability of the tube, as well as for ensuring that the tube meets the appropriate standards and specifications for its intended application.

Standard packing for steel Tubes

X1NiMoCuN25-20-7 stainless steel tubes are typically packed in a way that protects them from damage during transportation and storage, while also ensuring that they remain clean and free from contamination.
The standard packing for X1NiMoCuN25-20-7 stainless steel tubes typically includes the following:
