๐—ง๐—ฒ๐—ฒ๐˜€ are commonly used pipe connectors that unite or divide flow pathways in piping systems.

However, in pipes that require pigging (๐™ฅ๐™ž๐™œ๐™œ๐™–๐™—๐™ก๐™š ๐™ฅ๐™ž๐™ฅ๐™š๐™ก๐™ž๐™ฃ๐™š๐™จ), a particular sort of tee called a ๐—๐™–๐™ง๐™ง๐™š๐™™ ๐™ฉ๐™š๐™š is employed.

โ€“ Allows fluid to flow through the main pipe and branch out.

โ€“ Two types: Equal tee (branch is the same size as the main) and declining tee

โ€“ Governed by standards like ASME B16.9 or MSS-SP 75 for dimensions.

โ€“ Bars stop pigs from entering the branch pipes from the main pipe.

โ€“ Based on ASME B16.9/MSS-SP 75 tees, custom dimensions are used instead of universal ones.

โ€“ Some manufacturers adhere to ISO 15590-2 requirements.
