pipe coupling vs olets – Pipe Coupling VS Olets

The olet table is used to open the olet on the main pipe wall; the connection form with the main pipe is welding, and the connection mode with the olet may be butt welding, socket welding or thread; the main pipe and the olet connected by the olet table are vertical or oblique Cross relationship.

The pipe Coupling is used for the connection at the pipe joint of the two pipes; the connection mode of the two pipes to the pipe Coupling is socket welding or thread; the two pipes connected by the pipe Coupling have the same axial direction.

For pipe diameter

1. Sockolets: refers to the socket welding pipe table for pipe diameter DN15~DN40, see standard MSS-SP-97
2. Weldolet: refers to the butt welding pipe table for pipe diameter DN50 or above, see standard MSS-SP-97
3. Threadolet: Threaded pipe stand for pipe diameter DN15~DN40, see standard MSS-SP-97

Full coupling, socket welding, for pipe diameter DN15~DN40, see standard ASME B16.11, GB/T 14383-2008

Half coupling, socket welding, for pipe diameters DN15~DN40, see standard ASME B16.11, GB/T 14383-2008

The olet station is widely used in foreign countries in recent years. The reinforcing pipe fittings used for olet connection replace the traditionally used reducer tee, reinforcing plate and reinforced pipe section, etc., which are safe and reliable, reduce the cost; simple construction Improve the medium flow channel; serialization standardization, convenient design and other outstanding advantages, especially in high pressure, high temperature, large diameter, thick wall pipe.
