The threaded reducing flange and the pipe wall are connected by threads, and the additional pressure on the pipe wall is small. It is one of the widely used flange structure forms in engineering construction. It has the advantages of convenient on-site installation without need for welding. The sealing surface type has raised surface and flat surface.
Threaded reducing flange is the interconnecting parts between pipes, and are used for the connection between pipe ends; it is also useful for flanges on the inlet and outlet of the equipment to connect between two equipment, such as the reducer flange. Flange connection or flange joint refers to a detachable connection in which flanges, gaskets and bolts are connected to each other as a set of combined sealing structures. Threaded reducing flange refers to the flange used for piping in the pipeline installation, and the inlet and outlet flanges of the equipment when used on the equipment. There are holes on the flanges, and bolts make the two flanges tightly connected. The flanges are sealed with gaskets.
The flange is divided into threaded connection flange, welding flange and clamp flange. Flanges are used in pairs, wire flanges can be used for low-pressure pipes, and welded flanges for pressures of more than four kilograms. A gasket is added between the two flanges and then tightened with bolts. The thickness of threaded reducing flanges for different pressures is different, and the bolts they use are also different.
Precision stainless steel tube is safe, reliable, hygienic, environmentally friendly, economical and applicable. The thin wall pipe and the successful development of new reliable, simple and convenient connection methods make it more irreplaceable advantages of other pipes, and the application in engineering will become more and more. The use will become more and more popular, and the prospects are promising.
In particular, people are paying more and more attention to water quality issues, and their requirements are constantly increasing. Due to its corrosiveness, galvanized steel pipe will gradually withdraw from the stage of history under the influence of relevant national policies. Plastic pipes, composite pipes and copper pipes have become common pipe materials for piping systems. However, in many cases, precision stainless steel tube is more advantageous, especially thin wall stainless steel tube with a wall thickness of only 0.6～1.2mm in high-quality drinking water systems, hot water systems, and water supply systems that put safety and hygiene in the first place. It has the characteristics of safety, reliability, sanitation and environmental protection, and economical application.
