We are a stainless steel pipeline supplier engaged in fluid pipeline technology, specializing in the research and development, production and sales of fluid pipelines and accessories. We have been focusing on the research and development of stainless steel pipelines and their promotion and application. Scientific quality management system and advanced production equipment. Let’s introduce the connection method of stainless steel pipes
1. Pressing connection ——— It is divided into single pressing and double pressing. Double clamping is the most stable connection method. A radial contraction external force (hydraulic clamp) is used to clamp the pipe on the pipe, and the water is sealed by the O-ring to achieve the connection effect. The operation is convenient, the sealing is good, and it is not removable.
2. Expanded ring connection——–Using radial contraction external force (hydraulic pliers) to clamp the pipe fitting on the pipe, and through the water seal of the broadband rubber seal ring, to achieve the connection effect, detachable, pipe The installation increases the process of rolling the convex ring on the end of the pipe; the sealing is general, and the cost of the cast pipe is high.
3. Welding connection———Using the hot-melt process, the two connecting pieces are welded to achieve the connection effect. The connection strength is high, and the gas protection of the welding seam at the site is difficult to meet the standard, causing the weld to easily rust, which directly reduces the service life of the pipeline; the installation quality is strongly dependent on the welding workers, and the quality is difficult to stabilize
4. Self-locking connection-the earliest used for the connection of small-diameter plastic hoses, without the use of tools, quick installation. The inside of the interface is easy to loose and leak, and the sealing is poor.
