Product Description

Product Description

A grooved eccentric reducer is a pipe fitting used in piping systems to connect two pipes of different diameters with one end off-center. Eccentric designs gradually reduce pipe size, allowing controlled flow of fluids or substances. The "groove" aspect of pipe fittings refers to the method of joining, which typically involves grooves on the pipe ends, washers, and connecting systems.

The following are general guidelines on how to use grooved eccentric reducers in fire piping systems:

Prepare the pipeline:

Make sure both the larger and smaller pipes have grooves on the ends. This involves creating a groove or notch in the pipe end.
Gasket installation:

Place a washer on the grooved end of each pipe. Gaskets provide a seal between pipes to prevent leaks.
Grooved connection:

Slide the fittings over the grooved ends of the larger and smaller pipes. These connectors hold the pipe in place.
Eccentric reducer placement:

Insert the grooved end of the pipe into the opening of the grooved eccentric reducer.
Make sure the eccentric reducer is positioned correctly with the eccentric side facing the direction of the desired flow reduction.
Coupling installation:

Place additional couplings on the grooved ends of the pipe inside the eccentric reducer to secure the connection.
Fastening connection:

Use the appropriate tools to tighten the coupling securely to ensure a leak-free and reliable connection.
Follow manufacturer's guidelines:

Always follow the manufacturer's guidelines for the specific grooved eccentric reducer being used.
Comply with any applicable industry standards and codes for fire duct systems.
This type of fitting is typically used where it is necessary to gradually reduce pipe size while maintaining a grooved connection for quick and efficient installation. As with any duct system component, it is critical to consult the manufacturer's documentation and follow relevant industry standards and local codes for proper installation and compliance with safety regulations.

Quality Control:

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.
