7 Correct Ways to Attach Stainless Steel Hose Fittings :

1. The working principle of the compression fitting is to insert the thin-walled stainless steel tube into the socket of the compression fitting, and use a special compression tool to clamp the stainless steel tube in the fitting. The cross-sectional shape of the compression part is hexagonal. There is an O-ring seal between the pipe and the pipe fitting, which makes it have the characteristics of anti-leakage, anti-pulling, anti-vibration, and high-pressure resistance. Therefore, it is a relatively advanced connector in the direct drinking water system, tap water system, heating system, steam system, industrial oil pipe system, and industrial air pipe system. Suitable for water, oil, gas, and other pipeline connections.

2. Card sleeve connection, the connection method in which the pipe is compressed on the pipe fitting with the lock nut and the compression ring of the open pipe. Features: The sealing surface of the ferrule type pipe fittings is short, the installation is convenient and simple, no special tools are required, and it can be disassembled. It is generally used in tap water and gas systems with specifications below 2632.

3. The socket connection method is divided into mechanical interface and non-mechanical interface. The mechanical interface is connected with the flange on the pipe end by the pressure flange, and the rubber sealing ring is pressed into the gap between the cast-iron socket and socket so that the rubber ring is compressed and tightly attached to the pipe wall to form a seal. According to the different fillers, the non-mechanical interface is divided into asbestos cement interface, self-stressed cement interface, blue lead interface, rubber ring interface, and welding interface. There are two kinds of oil hemp wire and a rubber ring in the inner sealing ring of the socket.

4. Threaded connection, also known as a threaded connection, connects pipes with pipes, pipes and valves through internal and external threads. This connection is mainly used for the connection of steel pipes, copper pipes, and high-pressure pipes.

5. Flange connection is to fix two pipes or pipe fittings on a flange first, then add a flange gasket between the two flanges, and finally tighten the two flanges with bolts. A way of connecting them tightly together.

6. The welding of stainless steel pipes generally adopts argon arc welding for the bottom cover, manual arc welding for the cover surface, and argon filling in the pipe for protection, so that the welding seam inside the pipe does not oxidize. For stainless steel pipes with smaller diameters, the back cover and cover surface can also be directly welded by argon arc welding. After the stainless steel pipe is welded, the surface of the weld should be pickled and passivated.

7. Groove connection, also known as clamp connection, has become the first technology for connecting liquid and gas pipelines. The grooved pipe joint is a sleeve-type quick joint that is processed into an annular groove at the pipe joint parts such as pipes and pipe fittings and is composed of clamps, rubber sealing rings, and fasteners. During installation, after the special-shaped rubber sealing ring is put on the adjacent pipe ends, it is connected with a split clamp. After the inner edge of the clamp is seated in the groove and fastened with fasteners, the sealing performance of the pipeline is ensured. This connection method has the advantages of not destroying the galvanized layer of the steel pipe, fast construction, good sealing, and easy disassembly. It can be used for construction water supply, fire water supply, production water supply, and other pipeline projects.
