PRODUCTS DETAILS

A grooved reducing flex joint is a mechanical pipe joint that allows pipes of different diameters to be joined while providing a degree of flexibility. These couplings consist of two grooved end fittings and a flexible gasket or sleeve that is installed on the pipe. Grooves on the pipe ends provide a strong mechanical connection when the fitting is tightened.

Application:
Grooved reducing flexible joints are commonly used in a variety of piping systems such as:

HVAC (Heating, Ventilation, and Air Conditioning): Used to connect ducts in HVAC systems where flexibility may be required due to thermal expansion and contraction.

Fire Protection Systems: Typically used in fire sprinkler systems to connect pipes of different sizes while allowing for movement due to temperature changes.

Water and Wastewater Systems: For water and drainage systems where flexibility and ease of installation are important.

Industrial Piping: Used in industrial applications where grooved coupling systems are favored for their simplicity and speed of installation.

Material standards for groove couplings:
Material standards for grooved couplings are often set by industry organizations and standards bodies. The material used for grooved joints is usually ductile iron, but stainless steel and other materials can also be used, depending on the application and specific requirements.

Standards governing grooved couplings include:

ANSI/AWWA C606 - Groove and Shoulder Joints for Ductile Iron Pressure Piping and Fittings: This standard covers groove and shoulder joints for ductile iron pressure piping, fittings, and other components.

ASTM A536 - Standard Specification for Ductile Iron Castings: This standard covers compositional, mechanical, and other requirements for ductile iron castings.

NFPA 13 - Standard for Installation of Sprinkler Systems: This standard, published by the National Fire Protection Association, provides guidance for the installation of sprinkler systems, including the use of grooved joints.
