A butt-weld tee is formed by hydraulic bulging or hot extrusion from seamless tube, so the branch is reinforced by thickened material rather than by a welded saddle. The result is a smooth bore, uniform wall at the junction and predictable pressure containment.
Hydraulic bulge forming for DN15–DN300 keeps ovality ≤1% and gives a well-rounded branch transition.
Larger sizes are hot formed or fabricated from two seamless halves and full-penetration welded, then stress relieved.
All three ends machined to ASME B16.25 bevels matched to the pipe schedule.
Reducing tees are marked with run × branch dimensions, e.g. DN100 × DN80.
Seamless stamped 90° elbow, LR or SR, DN15–DN2000, to ASME B16.9 / GB/T 12459.
