As a widely used piping material in industry and daily life, stainless steel pipe is favored for its unique properties and superior durability.
First of all, let's understand the characteristics of the three types of stainless steel pipe 321, 410, 304. 321 stainless steel pipe has good corrosion resistance and high-temperature strength, and is suitable for work in high-temperature environments. 410 stainless steel pipe has good mechanical properties and corrosion resistance, and is suitable for work in general environments. While 304 stainless steel tube with its excellent corrosion resistance and good mechanical properties, in all types of environments are widely used.
First, corrosion resistance
The corrosion resistance of stainless steel pipe is mainly manifested in the following aspects:
1. The surface of stainless steel pipe forms a layer of dense oxide film, which can effectively prevent the erosion of oxygen and water molecules on the inside of the pipe, thus playing a role in corrosion prevention.
2. Stainless steel pipe has low corrosion rate and good corrosion resistance in seawater, fresh water, acid and alkali and other media.
3. Stainless steel pipe can still keep good corrosion resistance under high temperature environment and is not easy to be oxidized.
Second, alkali resistance
The alkali resistance of stainless steel pipe is shown in the following aspects. 1:
1. Stainless steel pipe can resist the erosion of alkali under alkaline environment and keep the integrity of the pipe.
2. Stainless steel pipe can still maintain good alkali resistance in high temperature alkaline environment.
3. Stainless steel pipe is not easy to occur pitting and crevice corrosion in alkaline environment such as seawater and fresh water.
Third, baking paint
Stainless steel pipe also has advantages in baking paint:
1. Stainless steel pipe surface treatment technology is mature, baking paint effect is good.
2. After baking varnish, the surface of stainless steel pipe is smooth and not easy to be stained with dust and bacteria.
3. baking varnish stainless steel pipe in the outdoor environment, can resist ultraviolet rays, acid rain and other erosion, keep beautiful.
Fourth, downpipe
Stainless steel pipe is also widely used in the field of downpipe:
1. Stainless steel pipe has excellent corrosion resistance, which can ensure the long-term stable operation of the downpipe in harsh environments.
2. Stainless steel pipe with smooth inner wall is not easy to be clogged, which is easy to be cleaned and maintained.
3. Stainless steel pipe has high strength, can withstand certain pressure, suitable for all kinds of downpipe.
V. Galvanized pipe
Although stainless steel pipe has excellent corrosion resistance, but in some environments, galvanized pipe is also a good choice:
1. Galvanized pipe has certain alkali resistance in alkaline environments.
2. galvanized pipe has a smooth surface that is less susceptible to dust and bacteria.
3. galvanized pipes are relatively inexpensive and are suitable for piping installations in general environments.
In short, 321, 410, 304 and other types of stainless steel pipe have excellent performance in corrosion prevention, alkali resistance, baking paint, downpipe, and galvanized pipe, which are widely used in various types of environments. When choosing stainless steel pipe, you need to choose the right model and specification according to the actual needs and working environment.
