Welded connection, threaded connection, tapered thread connection, annular pressure connection, flange connection.
1. welding connection: automatic argon arc welding or plasma welding is usually used for welding connections between stainless steel pipes and between pipes and fittings, and welding can be divided into butt welding and socket lap welding.
2. Threaded interface: After both ends of the thin-walled stainless steel pipe are threaded, there are internal and external threads at both ends of the pipe. external screw thread
3. Tapered thread connection: screw sleeve (? External thread)? Circumferentially weld the pipeline, and connect the pipeline with the pipe fittings with tapered threads. The way to complete the connection between pipes.
4. Ring-pressure interface: Ring-pressure interface is a flexible connection method that uses special tools to squeeze special sealing rings, pipe fittings and pipelines into a whole. Now this method should be recommended by most manufacturers of stainless steel water pipes, and it is also the only one with the highest frequency on the market. Meiya stainless steel water pipe is mainly pressed by double cards, which is very suitable for home pipeline decoration.
5. Flange connection: it can be divided into quick connection flange and movable connection flange.
Quick-connect flange connection is circumferential welding of flange and pipeline. After the gasket between flanges is pressed by the quick clamp, it plays a sealing role, thus completing the connection between pipes.
Grooved flanges and pipes? (? Or accessories)? Circumferential welding, using fasteners to play a sealing role through loose sleeve flange, mortise flange and sealing ring to complete the connection between pipes.
