Product Description

Products Details

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.
