What are the connection methods of stainless steel water pipes and which connection method is reliable?
In the current Chinese market, there are many connection methods for stainless steel water pipes, including flexible type, clamp type, flange type, compression type, etc. So which method is better for our family to use stainless steel water pipes? Which is more reliable?
Next, let's make a comparison:
Flexible connection is to insert the pipe into the pipe nozzle, tighten the nut with a wrench, seal the sealing ring with a compression ring, and then complete the connection. It is characterized by easy installation and can be disassembled at will, but the installation conditions must use a grooving machine to roll the groove at the end of the pipe to fix the C- groove.
2. Compression connectionThe method of
is to insert the pipe into the connecting pipe of the pipe fitting, tighten it with a nut, and compress and seal the shell of the connecting pipe through the sealing ring with screw force to complete the connection. The characteristic is that the installation is quick and detachable, but the connection reliability is relatively weak, and the thread is easy to loosen when vibrating, causing the nut to tighten. When the seal pressure is reduced, leakage will occur, and the cost of parts with complex structure is high and cannot be buried.
3. Flange connection
Principle: Flange and pipeline argon arc welding, fasten with quick clamps or bolts, and seal between flanges.
4. Single card press connection
The method is to insert the accessory into the accessory. The two ends of the accessory are protruding U-shaped grooves with built-in sealing rings, which are clamped and connected by special accessory tools and inserted into the parts.
5. Dual card pressure connection is an improved S-type card pressure connection technology based on single card pressure connection technology.
Features: Easy and quick installation, reliable sealing, anti-vibration, avoid loose joints, short installation cycle and low cost. It avoids quality defects caused by the considered factors. The O-ring in the pipe has a certain elasticity after compression. Automatic compensation after thermal expansion and cold contraction to ensure pipeline safety. The clamping connection diameter is less than or equal to 100mm. Therefore, the double clamp pressure connection method is also relatively simple and high-quality connection method, which has also become the main connection method of stainless steel pipes and occupies most of the market share.
