Recent years, with the popularization of thin-walled stainless steel pipes, more and more scenes use stainless steel pipe systems. Compared with polyethylene and polyvinyl chloride pipes, stainless steel pipes have their unique characteristics. Stainless steel has the advantages of long service life, low water resistance, pressure resistance, corrosion resistance, and environmental protection. If you want to get the job done, you must first use the tools, a good plumbing system cannot be separated from the correct connection method, let's take a look at several common stainless steel pipe connection methods:

stainless steel pipes

1. Stainless steel pipe press connection

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 into the fitting. The cross-sectional shape of the compression section is hexagonal, in addition, the stainless steel pipes and fittings have O-ring seals, making them leak-proof, stretch-proof, vibration-proof and high-pressure resistant. Therefore, it is an advanced connector in direct drinking water system, tap water system, heating system, steam system, industrial oil pipe system and industrial gas pipe system. Suitable for water, oil, gas and other pipeline connections.

2. Stainless steel pipe ring pressure connection

The stainless steel pipe ring pressure connection is a kind of extrusion connection, which sets a wide band sealing ring on the socket, and uses a special pressure ring tool to compress the socket to form an annular compression seal. After connecting, it can be rotated 360 degrees, which is convenient to adjust home supervisor on the construction site. Most importantly, its seals are superior to chlorinated "497" and are very generally applicable.

3. Stainless steel pipe welded connection

Welding connection is the best connection management method with tightness and stability. The welding of stainless steel water pipes has its unique characteristics. For different stainless steel materials, we must adopt various welding research methods and welding rods with different learning materials. Stainless steel welding rods must be Based on the base metal, the working environment conditions (including social working temperature and contact medium, etc.) are analyzed and selected, so that the students may not achieve the welding quality expected by the enterprise. At the same time, the welding construction process requirements are very high, and the welding must be protected by nitrogen. After welding, the weld must be protected. Otherwise, it is easy to cause problems such as leakage of stainless steel welded joints, resistance to intergranular corrosion, mechanical corrosion cracking, etc., resulting in water leakage. The welding connection method not only requires high cost, thick stainless steel pipes and fittings, but also the argon arc welding speed is not high, so the construction speed of the entire pipeline system is slow and difficult, and the total cost is high.

SS water pipes

4. Stainless steel pipe groove connection

The grooved pipe fittings are different from one-time forming of the double-card pipe fittings and the socket welding pipe fittings. They have the characteristics of disassembly and are generally suitable for fire protection and self-built water supply projects. The construction and installation of grooved fittings is very simple. The thin-walled stainless steel pipe is aligned with the mouth of the grooved pipe fitting, the sealing strip and the clamp are put on, and the fixing screw is tightened to realize the device. Grooved fittings are generally used for the connection of thin-walled stainless steel pipes with a diameter bigger than DN100.
