The models of large-diameter stainless steel tubes are usually named and identified according to their outer diameter, wall thickness, connection method and other parameters. The following are some common large-diameter stainless steel pipe models:
1. DN model: DN (nominal diameter) is used to indicate the diameter of pipes, valves, flanges, pipe fittings, seals, etc. Common DN models include DN15, DN20, DN25, DN32, DN40, DN50, DN65, DN80, DN100, etc.
Model indication: A stainless steel pipe is marked DN15. According to the standard size table, you can know that its inner diameter is 15mm, its outer diameter is about 23mm, and its wall thickness is about 4mm.
2. Specifications and models: Depending on the inner diameter and outer diameter of the tube, the specifications and models are also different. For example, common specifications include φ15mm×1mm, φ20mm×1.2mm, φ25mm×1.5mm, φ32mm×1.5mm, φ40mm×1.5mm, etc.
3. Pipe series: The pipe series refers to the ratio of the wall thickness of the pipe to the pipe diameter, which is usually used to indicate the load-bearing capacity of the pipe. Common tube series include SCH40, SCH80, SCH160, etc.
4. Pipe specifications: Pipe specifications refer to the outer diameter and wall thickness of the pipe, and are usually used to indicate the size and quality of the pipe. For example, common pipe specifications include Φ114.3×4.76mm, Φ219×8mm, etc.
