In the current Chinese market, there are many ways of stainless steel pipe connection, including flexible type, clamp type, flange type, compression type and so on. Which way is better for our family to use stainless steel water pipe?
Which one is more reliable?
Let's make a comparison
1. Flexible type
The connection method of flexible connection is to insert the pipe into the pipe orifice of the pipe fitting, tighten the nut with a wrench, seal the sealing ring with the compression ring, and then complete the connection. It is easy to install and can be disassembled at will, but the groove machine must be used to roll the groove at the end of the pipe to fix the c-groove.
2. Compression connection
The method is to insert the pipe into the connecting pipe of the pipe fitting, fasten it with the nut, compress and seal the shell of the connecting pipe through the sealing ring with the screw force and complete the connection. It is characterized by fast installation and disassembly, but relatively weak reliability of connection. The thread is easy to loose during vibration, resulting in nut tightening. When the pressure of the seal is reduced, leakage will occur. The cost of the parts with complex structure is high and cannot be buried.
3. Flange connection
Principle: argon arc welding of flange and pipeline, fastening with quick clamp or bolt, sealing gasket between flanges.
4. Single compression connection
The method is to insert the fitting into the fitting. Both ends of the fittings are protruding U-shaped grooves with built-in sealing rings, which are clamped by special fitting tools and inserted into parts.
5. Double compression connection is an improved S-type compression connection technology based on single compression connection technology.
Features: convenient and fast installation, reliable sealing, anti vibration, avoiding loose joint, short installation period and low cost. It avoids the quality defects caused by the factors considered. The O-ring in the tube has certain elasticity after compression. Automatic compensation after thermal expansion and cold contraction to ensure pipeline safety. The diameter of clamping connection is less than or equal to 100 mm.
Therefore, the double compression connection is also a relatively simple and high-quality connection method. It has become the main connection mode of stainless steel pipe, and occupies most of the market share.
