Driven by the rapid development of China's economy, all industries have achieved quite good development. The competition in the stainless steel pipe fittings market is also intensifying. As a downstream industry of the food and pharmaceutical processing and packaging sector, the influence of stainless steel pipe fittings is also growing increasingly significant.
Stainless steel elbows originated20Century80The era is an emerging industry. After a long time20After several years of pioneering and exploration, it has now taken shape to a certain extent. Stainless steel elbows are a type of pipe fitting, mainly made of stainless steel. With the development of the economy, the application scope of stainless steel pipe fittings is also getting wider and wider. By analyzing the corrosion resistance of the passivation layer on the surface of stainless steel and combining advanced production processes and equipment applications, the produced stainless steel clamps not only meet the needs of daily production and life, but also fill the domestic gap.
In the past decade, driven by the rapid development of China's macroeconomy, the stainless steel pipe fittings industry in China has developed very rapidly. Stainless steel pipe fittings are increasingly favored in both daily life and industrial applications for their environmental friendliness and safety, playing an important and irreplaceable role. A huge market is bound to have a fierce competitive situation. Compared with a few years ago, there are now too many enterprises in the industry, and the competition in product sales is too fierce.
Nowadays, society is an era of information explosion. It is inevitable for enterprises to encounter competitors in their products. The existence of competition in the industry is actually a good thing for some enterprises. Because of competition, enterprises have improved the quality of their products and services, and consumers have obtained better or more consumption and services with less money. While the industry is developing and progressing, the market is also eliminating the fittest among the enterprises within it. For some competitive large enterprises, through competition, their scale has become larger and larger and their popularity has become higher and higher.
With the rapid development of the stainless steel elbow market in our country, the application and research and development of core production technologies related to it will surely become the focus of attention for enterprises in the industry. If stainless steel pipe fitting manufacturing enterprises want to occupy a favorable position in the market, they need to constantly explore new application fields and strengthen brand upgrading to cope with fierce competition.
Stainless steel elbows have excellent corrosion resistance. The thin and solid oxide film on the surface of stainless steel endows it with excellent corrosion resistance in all water qualities, even when buried underground. Therefore, it is suitable for all kinds of water qualities. Besides disinfection and sterilization, there is no need to control the water quality. At the same time, there is no corrosion or excessive exudate, which can maintain the purity and hygiene of the water quality, eliminate secondary pollution, and withstand water quality up to a second30The high water flow impact of meters.
When stainless steel elbow manufacturing standard ball valves, globe valves and gate valves are used, they should only be fully open or fully closed. They are not allowed to be used for flow regulation to avoid erosion of the sealing surface and accelerated wear. The gate valve and the upper threaded stop valve are equipped with reverse sealing devices. By turning the handwheel to the highest position and tightening it, the medium can be prevented from leaking from the packing.
All the stainless steel pressed elbow pipe fittings are on the furnace coil rolling mill
The significant changes in the thermal mechanical history of length, especially in the production of micro-stainless steel pressed elbow pipe fittings, will strongly affect the degree of recrystallization, grain growth and separation that occur on the finishing mill. The technological innovation is too rapidgoogleOptimization has to be in line with international standards. Moreover, it leads to a drastic change in the microstructure and performance of all stainless steel pressed elbow pipe fittings in terms of length.
Elbows are used for the connection at the bends of pipes. Connect two pipes with the same nominal diameter to make a viewpoint turn of the pipeline. Elbows can be classified by raw materials into carbon steel elbows, cast steel elbows, alloy steel elbows, stainless steel elbows, copper elbows and aluminum alloy elbows. Elbows are commonly used pipe fittings for connection in stainless steel pipe fittings and stainless steel elbow devices, used for connection at pipe bends.
In a pipeline system, a elbow is a pipe fitting used to change the direction of the pipeline. By viewpoint, there is45°and90°180°The three most commonly used ones, and others are included according to the engineering requirements60°Other abnormal Angle elbows, etc. The materials for elbows include cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics, etc. The methods of connecting with pipes include: direct welding (the most commonly used method), flange connection, hot-melt connection, electrofusion connection, threaded connection and socket connection, etc.
Elbow manufacturers are classified by raw materials into carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, and argon chromium.PVC,PPREtc., classified by manufacturing methods, they can be divided into pushing, pressing, forging, and forging, etc. According to the manufacturing specifications, it can be classified into national standards, electrical standards, water standards, American standards, German standards, Japanese standards, Russian standards, etc. According to its radius of curvature, it can be divided into long-radius elbows and short-radius elbows. A long-radius elbow refers to one whose radius of curvature is equal to1.5Times the outer diameter of the pipe, that isR=1.5D. Short-radius elbows refer to those whose radius of curvature is equal to the outer diameter of the pipe, that isR=1.0D. (DIs the diameter of the elbowRIt is the radius of curvature. According to different shapes and uses, they can be classified as: grooved elbows, ferrules elbows, double socket elbows, flange elbows, reducing elbows, fixed seat elbows, inner and outer thread elbows, pressed elbows, pushed elbows, socket elbows, butt-welded elbows, and internal thread elbows.
Carbon steel welded elbow push manufacturing production process
At present, the technology of medium-frequency induction heating has been widely adopted in the production process of carbon steel welded elbow push manufacturing. This is a new process that is highly efficient and energy-saving.
When pushing larger-diameter pipe elbows, it is often necessary to add an insulation sensor in the steel pipe diameter reduction forming area to prevent the steel pipe from shrinking due to cooling by the ambient temperature and thus the pushing process from being blocked. The heating inductor and the heat preservation inductor are combined into a combined inductor for preheating before diameter change and heat preservation heating during diameter change forming. This combined sensor is not only necessary in the production of large-diameter pipe elbows, but also very effective in the production process of stainless steel elbows. However, this kind of sensor is rather difficult in design, impedance matching and power distribution adjustment. In addition, during the production process, there are also specific operational difficulties in heating the mandrel at the beginning of the push production, especially when heating the large-diameter mandrel used in the push production of large-diameter elbows.
