coupling pipe fitting

The pipe coupling or coupler plays an important role in connecting pipe sections and is used to stop leaks from broken or damaged couplings while maintaining the integrity of the pipe during the process. It is a very useful fitting for the pipeline and plumbing industry. Most pipeline installations require multiple sections of pipe to be joined together or cut to facilitate changes of direction and crossing obstacles. A pipe joint is a very short piece of pipe or tubing. It has a socket or internal thread at one or both ends. A pipe coupling allows two pipes or tubes of the same or different sizes to be joined together to form a long pipe.

Flexible couplings

Flexible couplings are designed to transmit torque while permitting some radial, axial and angular misalignment. They can accommodate angular misalignment up to a few degrees and some parallel misalignment. The flexible couplings allow some angular misalignment and axial movement, which means that they can be used to create smooth bends and absorb thermal expansion a contraction in the piping system. In some cases, traditional expansion joints, loops, and other expansion devices may even be completely excluded from the system with the use of flexible couplings. When assembling stretched rubber gasket that is slightly smaller than the pipe diameter of the two pipe ends and creates the first seal. The coupling halves are then placed around the gasket which adapts to them. The coupling halves are bolted together to further improve the sealing. When the piping system is pressurized, a ”pressure reserve” is created due to the profile of the gasket. The sealing lips are pressed at the increasing pressure harder down against the gasket seating surface which creates the third seal and makes the connection completely leak-proof and airtight. The working temperature of the gaskets is -34°C to +110°C.
