A hygienic pulled tee is a type of sanitary pipe fitting used to create a branch in a piping system where the branch is "pulled" or formed from the material of the main pipe run itself, rather than being a separate piece welded on. This manufacturing process results in a crevice-free, smooth internal finish that is essential for preventing bacterial buildup and ensuring product purity in hygienic applications.
Key Features and Benefits
The unique "pulling" or hydraulic bulging manufacturing method (often referred to as Tru-Bore®) offers distinct advantages over traditional fabricated tees.
Crevice-Free Interior: The single-piece construction, combined with internal bead rolling/removal, eliminates internal crevices and imperfections where bacteria or product residue could accumulate, thus facilitating effective cleaning.
Superior Strength: Pulled tees generally offer higher pressure capabilities compared to some other types of fabricated tees because the material is formed and strengthened during the manufacturing process, avoiding multiple weld points.
Optimal Flow: The smooth internal bore and seamless design minimize turbulence and pressure drop, contributing to efficient fluid transfer.
Material Traceability: Available in high-grade stainless steel, typically AISI 304L and AISI 316L, with material traceability a key feature for regulated industries.
