The ZT-76 covers pipe ID from 30mm-90mm, in wall thickness from 1.0mm-4.0mm, at line speeds of 15m/min-70m/min. Every line is built to order around the section, wall thickness and output the customer actually runs, so the roll tooling and forming section are set for that product rather than taken from a fixed catalogue.

High-frequency welding forms the strip into a tube and welds the longitudinal seam by applying a high-frequency current at the strip edges, without filler metal. The external weld bead is then scarfed, the tube passes through a cooling sink and a sizing section that brings it to its final dimension, and a computer-controlled flying saw cuts it to length on the run-out table.
