Equal tees are vital for pipeline branching, allowing for uniform fluid flow in three directions. These fittings are used to connect three pipes of the same diameter and are commonly found in industrial systems, chemical plants, and plumbing networks. Their high corrosion resistance and mechanical strength make them an essential part of the piping infrastructure.
