Vilka är anslutningsmetoderna mellan flänsslangar och rör i rostfritt stål?

This is the most common connection method. The two ends of the metal hose are equipped with flange plates, which are tightly connected to the flanges on the pipeline through bolts, with a sealing gasket placed in the middle to ensure sealing performance. This connection method is convenient for installation and disassembly, can withstand high pressure, and is suitable for various pressure and temperature pipeline System .

The end of the metal hose is directly welded to the pipe. This connection method has good sealing performance, high strength, and can withstand high temperatures and high pressures. However, it has high requirements for welding technology and is relatively difficult to maintain and replace. It is often used in some pipeline systems with extremely high sealing requirements, such as in the chemical and petroleum Industries .

The ends of the metal hose are machined with external threads, and the pipes are machined with corresponding internal threads. The connection is achieved by screwing the threads together. This connection method is simple and convenient, and is suitable for small-diameter, low-pressure piping systems, such as water supply and drainage pipes in some civil buildings. However, the sealing performance of the Trådad anslutning är relativt dålig, och tätningsmaterial som tätningstejp och tätningsmedel krävs vanligtvis för att läggas till .

Connect the metal hose to the pipe with a hose clamp. First, insert the metal hose into the hose clamp, then install the hose clamp on the pipe. Tighten the bolt on the hose clamp to make it tighten, thus closely connecting the metal hose and the pipe. This connection method is fast to install, easy to disassemble and maintain, but its sealing performance and Tryckmotstånd är relativt begränsade . Det används ofta i vissa rörsystem som kräver hög installationshastighet och lågt tryck, såsom ventilationsrör och vissa dräneringsrör .
