An Equal Tee and a Reducing Tee are both types of pipe fittings used to connect three pipes. Here’s an overview of their dimensions and characteristics: Equal Tee Dimensions Definition: An equal tee has all three outlets of the same diameter. It splits the flow of fluid or gas into two equal directions. Common Dimensions: Nominal Pipe Size (NPS): Varies from ½” to 48” (standard sizes). Outside Diameter (OD): Matches the pipe size. Run and Branch Lengths: Typically proportional to the NPS. Wall Thickness: Based on the pipe schedule (e.g., SCH 10, 40, 80). Standards: ASME B16.9, DIN, and MSS-SP standards. Reducing Tee Dimensions Definition: A reducing tee has a branch outlet smaller in diameter than the main pipe. It is used to connect pipes of different diameters. Common Dimensions: Nominal Pipe Size (Run): Matches the main pipe size (½” to 48”). Branch Size: Smaller than the run size (as required). Outside Diameter (OD): Larger for the run than the branch. Wall Thickness: Varies based on the schedule and standards. Standards: Similar to Equal Tee (ASME B16.9, DIN). Key Considerations for Both Fittings Material: Typically made of stainless steel, carbon steel, or alloy steel. Angle: The branch is usually at a 90-degree angle to the run. Weight: Depends on material grade, size, and wall thickness. End Connections: Butt-weld or threaded, depending on the requirement.
