Product Description

Products Details

A threaded and grooved reducing cross is a pipe fitting that combines threaded and grooved connections to provide flexibility in pipe connections in piping systems. In fire piping systems, this type of fitting can be used to connect four pipes of different diameters to distribute or combine flow as needed. The threading aspect involves using threads on pipes and fittings to screw them together to form a strong joint. The groove aspect usually involves grooves on the pipe ends as well as gaskets and connection systems to ensure a sealed connection.

The following are general guidelines on how to use threaded groove reducing spools in fire duct systems:

Prepare the pipeline:

Make sure the ends of the pipes being connected have the correct threads and grooves.
Threaded ends should have compatible threads per ANSI/ASME B1.20.1 or similar standards.
The trench ends should have the required grooves to facilitate trench connection.
Apply thread sealant:

Apply thread sealant or tape to the threaded portion of the pipe to ensure the threaded connection is tight and leak-free.
Insert the pipe into the fitting:

Insert the threaded end of the pipe into the corresponding threaded opening on the threaded groove reducing cross.
Make sure the pipe is securely screwed into the fitting.
Grooved connection:

Apply the gasket to the grooved end of the pipe.
Slide the coupling over the grooved end to secure the pipe in place.
Protect the connection:

Use appropriate tools to tighten threaded connections securely.
Make sure the grooved connection is properly sealed with couplings and gaskets.
Follow manufacturer’s guidelines:

Always follow the manufacturer’s guidelines for the specific thread groove reducing cross being used.
Comply with any applicable industry standards and codes for fire duct systems.
It is critical to comply with local fire codes and regulations as well as the guidelines provided by the accessory manufacturer. Additionally, make sure the system is installed by qualified professionals to meet safety and performance requirements.
