How to Choose the Right Sizes for a Mechanical Tee?

Apr 7, 2024 | NEWS

Mechanical tees are pipe fittings using as an alternative to full-flow cast fittings. They serve various purposes in plumbing and piping systems. Let’s delve into the mechanical tee detail:

Mechanical Tee Sizes and Types

  • Threaded Mechanical Tee: These frequently employes when the primary pipe’s diameter does not exceed 1 1/2 inches, making them optimal for use in modest residential plumbing setups.
  • Grooved Mechanical Tee:
  1. Small Tees: Generally sizes between 1/2 inch and 2 inches, these are commonly utilizing in residential plumbing setups.
  2. Medium Tees: With sizes ranging from 2 1/2 inches to 8 inches, these are typically using in commercial and industrial plumbing configurations.
  3. Large Tees: 10 inches and above, primarily used in industrial applications.

Applications of Mechanical Tee:

  • Fire Protection Systems: Grooved mechanical tees are extensively used in fire protection systems due to their reliable connections and ease of installation. They ensure efficient water flow throughout the system, providing reliable fire suppression capabilities.
  • Plumbing Systems: These tees are utilized in plumbing networks to link water supply and drain lines. Their grooved structure guarantees firm and leak-proof connections, bolstering the overall reliability of the plumbing setup.

Different Sizes and Applications of Grooved Mechanical Tee:

  • Small-Sized Grooved Mechanical Tees (typically ranging from 1/2 inch to 2 inches): Frequently employed in residential plumbing scenarios, these fittings are ideal for joining smaller pipes within various systems, including water supply lines, irrigation setups, and household plumbing fixtures.
  • Medium-Sized Grooved Mechanical Tees (ranging from 2 1/2 inches to 8 inches): Find applications in commercial and industrial plumbing systems. Ideal for joining pipes in larger-scale projects, including HVAC systems, fire protection systems, and water distribution networks.
  • Large-Sized Grooved Mechanical Tees (ranging from 10 inches and above): Mainly applied in industrial settings, these fittings are prevalent in expansive piping networks typically encountered in power plants, manufacturing plants, and facilities engaged in chemical processing.

Considerations to select the appropriate size:

Nominal Pipe Size (NPS):

Mechanical tees are sold based on the nominal pipe size they fit. For instance, if you have a 3-inch pipe, choose a mechanical tee with a housing that fits around a 3-inch nominal pipe. The housing’s inner diameter typically matches the pipe’s actual outer diameter.

Flow Requirements and Pressure:

Consider the diameter of the main pipe and the flow rates within your system. A tee that is too small may result in high-pressure differentials, potentially leading to leaks or damage. Opt for a mechanical tee size that ensures balanced pressure distribution and system stability.

Type of Tee:

Mechanical tees come in various types, such as threaded or grooved. Choose the appropriate type based on your specific application (e.g., residential plumbing, fire protection, industrial systems). Different sizes cater to different project requirements.
