◆ Product picture
For the stainless steel pipe, we have different steel grade, surface, color, specific specification will be made as per customer's requirement and decoration details.
The environmental protection of the substrate is the basic condition for healthy pipes. Stainless steel is a recognized health material that can be implanted into the human body. Household stainless steel pipes are generally mainly decorative articles, water pipes, etc. The thin-walled stainless steel pipe for quick-connecting water supply uses 304 (0Cr18Ni9) austenitic stainless steel material and has excellent corrosion resistance in oxidizing acid (HNO3).
The frictional resistance is small: the inner wall is smooth and the flow is large;
Impact resistance: tensile strength is twice that of steel pipe and 3 times that of copper pipe;
Economical: Good overall performance, can effectively control the leakage rate of the pipe network; from the perspective of product life cycle cost, the economy is more significant.
The sealing performance is good: the long service life of the stainless steel pipe system is the same as the life of the building. Therefore, people have no doubt about the service life of the stainless steel pipe when selecting the pipe product. The most concerned part is the weak part of the stainless steel pipe - the seal Performance and longevity. The quick-connecting connection method absorbs the traditional welded connection. The welding process is not required within the construction process of DN15-100, so that the pipe and the pipe fittings are integrated into one body, and the welding auxiliary material can be saved in time and time, and the pressure resistance, airtightness and cold drawing are adopted. Experiments such as negative pressure and salt spray can prove that after the on-site pressure test is qualified, there is no loss caused by maintenance work. It has the characteristics of wide application range, high cost performance, simple pipe fitting structure and obvious cost performance.
◆ Why choose stainless steel material pipe?
Because it has its own excellent advantages
The tensile strength of 1.304 thin-walled stainless steel pipe is twice that of steel pipe, which is 3~4 times that of copper pipe and 8~10 times that of plastic pipe. The strength of the material determines whether the water pipe is strong and crash resistant, safe and reliable.
2. The engineering community praised the stainless steel pipe as one of the best environmentally friendly pipe types used in the water supply system in the 21st century. Not a transitional product.
3. In the notice of the “National Civil Engineering Design Technical Measures” issued by the Ministry of Construction on January 2, 2003, it is emphasized that the new stainless steel pipes should be preferred.
4. The Ministry of Housing and Construction's Kangju certification project recommends the use of pipeline materials.
◆Stainless Steel pipe will rust or not?
Many people think that stainless steel pipes will definitely not rust, which is a wrong view. First, the stainless steel tube's rust and corrosion resistance are conditional. The stainless steel pipe is a steel pipe that does not rust in a weak corrosive environment such as the atmosphere or fresh water, and the amount of chromium contained in the steel must be greater than or equal to 12%. If the chromium content is low or not used in a weak corrosive environment such as the atmosphere, rust will occur. Acid-resistant steel pipes are steel pipes that are resistant to corrosion in strong corrosive media such as acids, alkalis, and salts, but they are not necessarily corrosion-free. For example, the type of medium, temperature, concentration, impurity content, flow rate, pressure, etc. will affect it. There are no stainless steel pipes in the world that do not rust or corrode under any conditions.
Stainless steel tube corrosion principle
Stainless steel tube corrosion is simply a damage and failure between stainless steel and corrosive media due to chemical and electrochemical interactions. According to the nature of corrosion, it can be divided into chemical corrosion (corrosion generated in flying electrolyte solution, such as oxidation of stainless steel tube at high temperature) and electrochemical corrosion (steel and stainless steel pipes in humid atmosphere, aqueous solution and acid-base salt, etc.) The corrosion generated in the electrolyte solution has ion/electron generation during the corrosion process, and the essence of the electrochemical corrosion is the function of the primary battery).
So, how do we maintain the stainless steel pipe?
Stainless steel tube anti-corrosion method
(1) Correct and reasonable use of stainless steel pipe
Choose the right stainless steel tube in different environments
(2) Cover the surface of the stainless steel tube with a protective layer
For the cover layer, everyone thinks of painting, the surface of the stainless steel tube is quite smooth, the paint is difficult to spray, and it will be easy to fall off after a long time. Stainless steel pipe is corrosion-resistant steel. It will rust if it is handled improperly. If the paint is sprayed on the stainless steel pipe simply, the strong corrosive chemical composition of the paint itself can easily corrode the surface of the stainless steel pipe, causing the surface of the stainless steel pipe. Rusty phenomenon.
For stainless steel tube coating, HONGSUN also uses a common method, vacuum coating, vacuum coating is a thin layer of color attached to the surface of stainless steel tube, will not damage the original surface form of stainless steel tube, stainless steel tube is not easy to rust . Therefore, the preferred method for color treatment of stainless steel tubes is vacuum coating, which does not require painting. In addition, we also apply color plating to stainless steel tubes, using modern science and technology to cover a layer of paint, strong adhesion, difficult to paint, that is, beautiful and practical, with superior corrosion protection.
