There are many processing methods for antibacterial stainless steel pipes. There are pipe stripping, welding, pipe expansion, shrinking, hot extrusion, cold extrusion, hot rolling, cold rolling, stamping, etc. The processing methods used for antibacterial stainless steel are different for different uses. For example, the country is now promoting thin-walled antibacterial stainless steel water supply pipes, which use antibacterial stainless steel strips that are heated and welded to form antibacterial stainless steel pipes; large-diameter antibacterial stainless steel pipes installed on industrial pipelines Stainless steel elbows are processed by stamping, and installation elbows with irregular angles that are assembled at the construction site after being cut into several sections by plasma are processed by welding. Antibacterial stainless steel pipe cutting: Antibacterial stainless steel pipes are generally 6 meters long. Cutting is the basic type of antibacterial stainless steel pipe processing, including ordinary grinder cutting, circular saw cutting and precision cutting. Precise cutting can shorten the antibacterial stainless steel pipe to 2 mm, and ensure that the cut antibacterial stainless steel pipe has no burrs and the loss can be controlled to within 1mm. Antibacterial stainless steel pipe welding: Welding is also an essential process for antibacterial stainless steel pipe processing. The most...
1. Stainless steel welded pipe material selection Stainless steel welded pipes must pass non-destructive testing, and the welding joints need to be inspected and the welding joints are required to be smooth. Select the material according to the corrosiveness of the flowing liquid or gas, select the pipe diameter according to the flow rate, and select the wall thickness according to the wall pressure requirements. The sealing materials of all valves, pipes and manholes must be qualified. 2. Stainless steel welded pipe manufacturing The upper and lower heads are molded or spun. When assembled with the cylinder, they are mainly docked. All interface parts are mechanically flanged to ensure a sophisticated transition. All welds must not be lower than the base metal. Ideally, they should be flush with the base metal. If they are higher than the base metal, the parts above the base metal must be sophisticated and must not have pits or pits. When docking and welding, ensure that the inner walls of the pipes are connected without gaps. During welding, the stainless steel welded pipes must be fully protected by argon gas, and the purity of the argon gas must reach more than 99%; all welds must...
Fire piping includes two systems: fire hydrant system and water sprinkler system. As far as the editor of Zhongxing Yide knows, the stainless steel fire protection piping system is a widely used fixed fire protection facility in China. Nowadays, 304 stainless steel pipes are used in fire water supply pipes in sprinkler systems. As we all know, the service life of stainless steel pipes is relatively long, which can reach 100 years, and the shortest is at least 70 years, which is as long as the life of the building. Furthermore, the most outstanding corrosion resistance among many pipes is stainless steel pipes, because stainless steel will passivate with oxidants, forming a protective film on the surface of stainless steel, which can prevent further oxidation reactions from occurring. In addition, stainless steel can be recycled without causing environmental pollution, so stainless steel waste also has great economic value. The tensile strength of 304 stainless steel pipes is very high, 2 times that of steel pipes and 8 to 10 times that of plastic pipes. It also has good ductility and toughness, so 304 stainless steel pipes can withstand vibration, impact, thermal expansion and contraction well. It does not leak, does...
With the rapid development of our country’s economy, especially with the steady development of China’s industrialization process, my country’s antibacterial stainless steel pipe industry has gradually entered a mature stage. Antibacterial stainless steel pipe is a versatile stainless steel that is widely used in manufacturing products that require good comprehensive The demand for equipment and parts with excellent performance (corrosion resistance and formability) is increasing day by day. Below we will introduce to you in detail the commonly used 304 antibacterial stainless steel pipes. There are many types of antibacterial stainless steel pipes, but the main uses are as follows: Classification of antibacterial stainless steel pipes 1. Classification according to production method: (1) Seamless tubes – cold drawn tubes, extruded tubes, cold rolled tubes; (2) Welded pipe; (3) Classification by process – gas shielded welded pipe, arc welded pipe, resistance welded pipe (high frequency, low frequency); (4) According to the welding seam – straight seam welded pipe, spiral welded pipe. 2. Classification according to cross-sectional shape: (1) Round steel pipe; (2) Rectangular tube. 3. Classification by wall thickness – thin-walled steel pipes, thick-walled steel pipes 4. Classification by use: (1) Civilian pipes are divided into round pipes, rectangular pipes, and...
