1. Pressure connection: The working principle of compression pipe fittings is to insert a thin-walled stainless steel pipe into the socket of the compression pipe fitting, and use a special compression tool to clamp the stainless steel pipe into the cross section of the compression section of the pipe fitting. The shape is hexagonal. In addition, stainless steel pipes and fittings have an O-shaped seal, making them leak-proof, anti-stretching, anti-vibration and anti-high pressure.
2. Ring-pressure connection: Ring-pressure connection is an extrusion connection. A wide-band sealing ring is set on the socket, and a special ring-pressure tool is used to press the socket to form a ring-shaped compression seal. It can be rotated 360 degrees after connection, making it easy to adjust and supervise at the construction site.
3. Welded connection: Welded connection is the connection management method with the best sealing and stability. Stainless steel electrodes must be based on the base metal, and must be sensitive to the working environment conditions (including social working temperature and contact media, etc. ) for analysis and selection. The weld must be protected after welding. Otherwise, it is easy to cause leakage of stainless steel welded joints, resistance to intergranular corrosion, mechanical corrosion cracking and other problems, leading to water leakage.
4. Grooved connection: Different from the one-time molding of double-carded pipe fittings and socket welded pipe fittings, grooved pipe fittings are detachable. The construction and installation of grooved pipe fittings are very simple. Thin-walled stainless steel Align the pipe with the grooved pipe fitting, put on the sealing strip and clamp, and tighten the set screws to obtain the groove fitting of the device. It is generally used to connect thin-walled stainless steel pipes with diameters greater than DN100.
