The ZT-30 covers pipe ID from 13mm-30mm, in wall thickness from 0.4mm-1.5mm, at line speeds of 3m/min-7m/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.

Stainless tube is welded with an argon arc welder rather than at high frequency, which suits the thinner wall range and keeps the weld zone clean. The line runs a single-head uncoiler, a clean slot with a strip steel guide, the welding station with weld-joint polishing, a horizontal roller train, and a cutting saw.
