In terms of pipeline connection technology, Twitch Company has the courage to innovate and break through the tradition, and has more than 10 patented technologies with independent intellectual property rights, creating a "patented technology of convex ring connection" that has reached the world leading level. This technology has changed the method that the traditional metal pipe connection needs to be twisted or grooved to destroy the pipe end. By using a special convex ring expanding tool, a circle of convex rings, commonly known as "reinforcing ribs", are expanded on the thin-walled stainless steel pipe end, which not only does not damage the pipe end, but also effectively improves the radial pressure and radial external tensile strength of the pipe end, and completely solves the world problem of "wall thickness exceeding the standard" of traditional metal pipes. Convex ring connection technology is a great innovation in metal pipeline industry and a breakthrough in connection mode. In the same pipe diameter and working range, this technology can save four fifths of metal materials and increase the installation and construction time by three times. If it is widely used in China's pipeline industry, it can save 2-3 million tons of steel every year. At present, there is no report about this connection at home and abroad. Compared with the connection mode of thin-walled stainless steel water pipes abroad, it is advanced to some extent and belongs to the new technology which is original in China and advanced in the world. Appraised by the Expert Appraisal Committee of Scientific and Technological Achievements organized by Guangdong Provincial Department of Science and Technology, it is agreed that the convex ring connection technology fills the gap in China and reaches the leading level in China. And has won many international awards: Gold Award in 2002 Geneva International Patent Technology Achievement Expo, Gold Award in 2004 Hongkong International Patent Technology Patent Product, the highest honor "Golden Crown" Award in 2004 British International Invention Expo, Eureka World Invention Gold Award in 2004, International High-tech Achievement Award in 2004 British International Science Center, paladin International Invention Gold Award in 2005 and paladin International Science Center in 2005.
When the patented connection technology of convex ring is applied to thin-walled stainless steel pipe, it is called "convex odd pipe" for short. It not only perfectly solves the problem of difficult connection in the installation and construction of thin-walled stainless steel water pipes, but also forms a sealed connection with Tuqi stainless steel pipe fittings, which has firm and reliable work, excellent impact resistance and tensile strength, good sealing performance and simple and fast operation. It also has various advantages and characteristics of high-quality stainless steel: when applied to fluid pipelines, it has the advantages of good rigidity, small expansion coefficient, temperature resistance, corrosion resistance, no scaling, smooth inner wall, small fluid resistance, bright outer wall, durability, sanitation and environmental protection. The service life of the convex odd pipe is basically the same as that of the building, and it hardly needs to be updated and maintained. It is the "all-round champion pipe" with excellent comprehensive performance among pipeline materials at present, and can replace copper pipes, steel-plastic pipes, galvanized pipes, aluminum-plastic pipes, PP-R pipes and UPVC pipes. It has a broad market prospect and can be used in pure water system, hot water heating, air conditioning chilled water supply, fire fighting and so on. , which can be applied to industries such as shipping, food, beverage, petrochemical industry, etc. It will lead the development direction of the world pipeline industry in the next few decades.
