304 stainless steel water pipes are divided into two series products: clamping type and assembling type. The specifications of each series of products are different, and the pipe diameters range from DN 15 to DN 100. The price of each specification is different, and so is the price of each specification. The price ranges from 20- 150, so it is better to find the manufacturer directly.
Second, the reasons for the price difference of 304 stainless steel water pipes
1, calendering
The exact thickness of stainless steel tube is closely related to the rolling quality of its steel strip, but the rolling cost is divided according to different thicknesses. The thinner, the more processing cost per ton of calendering. Of course, sometimes the extra-thick and non-extra-thick calendering costs are different.
2. Output
Every stainless steel pipe manufacturer certainly likes to produce those commonly used thick pipes, which are about 0.42mm thick, because this thickness and polished stainless steel pipes have higher yield. However, customers' needs are varied, and some need thin-walled pipes, such as stainless steel pipes with a real thickness of 0.25mm to 0.31mm. Due to the thin steel strip, the requirements for pipe making or polishing are higher and the yield is lower, so the higher the rejection rate, the higher the pipe cost.
3. Damage problem
Because the inner wall of pipe is thin, the breakage rate is higher than that of thick pipe, whether it is stored by manufacturers or transported by logistics, which also involves the problem of damage compensation.
There are various factors in pricing, but the main reason for the price difference between thin-walled tube and thick-walled tube is calendering cost and output.
Third, the difference between 304 stainless steel water pipes and 3 16 stainless steel water pipes
The full name of "stainless steel" in our spoken language is "stainless and acid-resistant steel"-it not only does not rust, but also resists acid and alkali corrosion. All stainless steels can be rustless, but their corrosion resistance and mechanical strength are different-they are divided into different brands according to this ability, and 304 and 3 16 are two of them.
For these two kinds of water pipes with different materials, their application scope will be different accordingly. The Ni (Nickel) content in the composition of 3 16 stainless steel water pipe is 10.0- 14.0, which makes the 3 16 stainless steel water pipe have high hardness and ductility, and can be highly polished and corrosion-resistant. The content of Cr (Cr) is 16.0- 18.0, which makes the 3 16 stainless steel water pipe have a variety of high strength, corrosion resistance, wear resistance, high temperature resistance and oxidation resistance. It can be used in areas with high chloride ion, such as seaside.
The contents of Ni (Ni) and Cr (Cr) in 304 stainless steel water pipe are 8.0- 10.5 and 18.0-20.0, respectively. It can be seen that the hardness of 304 stainless steel water pipe is lower than that of 3 16 stainless steel water pipe, and it is more dominant to use 3 16 stainless steel water pipe in important fields such as industry, medical equipment, food and beverage, aviation equipment, etc. 304 stainless steel water pipe is suitable for light industry and building water supply system.
