The ASME B16.9 Stainless Steel 316L Straight Tee is a high-integrity fitting used to create a 90° branch from a main pipeline. With "Straight" (Equal) geometry, the branch and header share the same diameter. Forged from low-carbon 316L, it offers exceptional resistance to chloride-induced pitting and intergranular corrosion. The SCH40 wall thickness provides a robust pressure rating, making it the preferred choice for marine, pharmaceutical, and chemical processing where leak-proof, high-purity branch connections are mandatory.
