Stainless steel water tube making machine

The outer diameter of the stainless steel water pipe is the edge metal pipe wall, and the pipe wall is thinner, which is not much different from the pipe diameter. The inner diameter and outer diameter of the solid pipe wall are called the pipe diameter. The diameter of the outer circle of a circle is called the outer diameter, which is generally measured with a vernier caliper, and the symbol Φ is used to indicate the measurement mark. In water supply engineering, the outer diameter is a very important parameter, which needs to be handled carefully before purchase. The outer diameter of stainless steel water pipes is usually marked by the size and wall thickness of the adopted diameter. For example, a stainless steel water pipe with an outer diameter of 101.6mm and a wall thickness of 2mm can be marked as D101.6*2

The pipe quality also have different standard.
