A grooved reducing tee is a special type of pipe fitting used in piping systems. It is designed to connect three pipes of different diameters in systems requiring fluid flow or material transfer. A reducing tee has two openings of the same size and a third, smaller opening. Grooving in fittings refers to a method of joining pipes, usually involving grooved ends on the pipes that are held together by gaskets and fittings.
The function of a grooved reducing tee in a piping system is to achieve effective and controlled flow of fluids or substances by connecting pipes of different sizes. This type of tee is typically used when there is a need to distribute or combine flows of different volumes or to accommodate changes in pipe diameter within the system.
Standards for grooved pipe fittings are often set by industry organizations or regulatory agencies to ensure compatibility, quality and safety. American National Standards Institute (ANSI)/National Fire Protection Association (NFPA) Standard 53 is a widely recognized standard for grooved pipe fittings that covers grooved end pipe fittings used in fire protection services. Another standard is International Organization for Standardization (ISO) 6182, which provides specifications for grooved end fittings for metal pipes.
Be sure to check the specific standards and codes that apply to your region, industry, or project as they may vary. Consulting local building codes, industry regulations, or manufacturer guidelines is critical to ensuring compliance and safe operation within your duct system.

what is the rigid and flexible Coupling difference?
Coupling play an important role in connecting pipe segments to prevent leaks caused by damaged or damaged joints while maintaining the integrity of the pipe in the process. It is a very suitable fitting for the pipe and pipe industry. Most pipe installations require multiple pipe sections to be joined together or cut to facilitate changing direction and traversing obstacles. A fitting is a concise pipe or pipe. It has a socket or female thread at one or both ends. Fitting allows two pipes or pipes of the same or different sizes to be joined together to form a long pipe.
Flexible coupling
Flexible couplings are designed to transmit torque while allowing some radial, axial and angular misalignment. They can accommodate angular misalignment of up to a few degrees and some parallel misalignment. Elastic couplings allow for some angular misalignment and axial movement, meaning they can be used to create smooth bends and absorb thermal expansion contractions in piping systems. In some cases, the use of elastic couplings can even exclude conventional expansion joints, loops and other expansion devices from the system entirely. When assembling a stretch rubber gasket, the gasket is slightly smaller than the pipe diameter at both pipe ends and produces the first seal. The two halves of the coupling are then placed around the washers that adapt to them. The coupling halves are bolted together to further improve the seal.
