Stainless Steel Pipe & tube Technical Size
The diameter of a stainless steel pipe or tube is commonly referred to as its nominal size (DN). The nominal size of a pipe or tube is not the same as its actual size, but rather it is a reference to a standard size based on historical conventions.
For example, a 1-inch pipe has a nominal size of DN25, even though its actual outer diameter may be slightly larger or smaller than 1 inch.
The thickness of a stainless steel pipe or tube is commonly referred to as its schedule or wall thickness.
The schedule number is a reference to the thickness of the pipe or tube wall, and it is specified using a standard schedule chart. The most commonly used schedule charts are the ASME B36.10 and B36.19 standards.
Stainless steel pipes and tubes are typically available in a range of standard sizes, but they can also be manufactured to custom sizes and dimensions. The following are some of the most common sizes and dimensions of stainless steel pipes and tubes:
- Seamless Stainless Steel Pipes and Tubes:
- Outer diameter: 6mm to 630mm
- Wall thickness: 0.8mm to 30mm
- Length: Up to 12m
- Welded Stainless Steel Pipes and Tubes:
- Outer diameter: 6mm to 3,000mm
- Wall thickness: 0.3mm to 30mm
- Length: Up to 12m
- Stainless Steel Pipe Fittings:
- Nominal size: DN6 to DN1200 (1/8" to 48")
- Wall thickness: Schedule 5S to Schedule XXS
- End connections: Butt weld, Socket weld, Threaded
It is important to note that the actual dimensions of a stainless steel pipe or tube may vary slightly depending on the manufacturing process, and therefore it is important to consult the relevant standards and specifications to ensure that the correct size and dimensions are specified for a particular application.
