ASTM A325 Tees
ASTM A325 Tees refers to pipe tees (components used to join or branch a piping system, typically conforming to ASTM A234 Grade WPB) used in piping systems that are secured by ASTM A325 high-strength structural bolting. While A325 specifies the high-strength bolt material, the term is used in this context to denote piping connections where the structural integrity of the joint, achieved through the A325 fasteners, is critical. These high-strength assemblies are vital in industrial and utility piping where robust construction is required for the separation or merging of fluid flows. Zeron Fastners supplies the necessary tee components and A325 bolting for these critical high-load pipe connections.
