This is a tack-welded stainless steel tee (three-way pipe fitting). Wall thickness: 1.65 mm. Diameter: 50.8 mm. It requires manual TIG welding with full penetration using a single-sided welding, both-side forming technique. The weld produces both an internal bead and an external bead. After welding, cutting shall be performed based on the actual dimensions
