Product Introduction

Seamless stainless steel pipe can not only provide a variety of size specifications for different needs of consumers to choose, but also its own can correspond to a variety of styles and thickness and other parameters, so we need to clear their actual demand budget when purchasing, referring to the specification of various products to choose, When necessary, you can refer to the advice of professionals such as the above to choose, in order to have a reliable quality, qualified and suitable seamless stainless steel pipe.

National standard thickness of seamless stainless steel pipe

Diameter indicates the diameter of a circle

Diameter DN: indicates the nominal size of the pipe diameter

nominal diameter (also known as mean outside diameter).

This is due to the fact that the wall of the metal pipe is very thin, and the outer diameter of the pipe is almost the same as the inner diameter of the pipe, so the average value of the outer diameter of the pipe and the inner diameter of the pipe is called the diameter of the pipe.

Nominal diameter is based on the metric system mm, called DN (metric unit)

For example, if a DN100 tube encounters a thin-walled tube, its inner diameter will be greater than 100mm, but when it encounters a thick-walled tube, its inner diameter will be less than 100mm. But take 100mm for calculation. Also known as DN100

Because the units are divided into metric (mm) and British (inch), there are the following methods of address.

1. Based on the metric system (mm), called DN (metric unit)

2. NB(inch unit) based on British (inch)

3. DN (nominal diameter)

NB (nominal bore)

OD (outside diameter)
