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.

Where ZT-76 sits in the range
Published range for the ZT-76: 30mm-90mm pipe, 1.0mm-4.0mm wall, 15m/min-70m/min. In the eight-model range it sits between the ZT-60 (25mm-80mm, 30m/min-100m/min) and the ZT-127 (32mm-127mm, 20m/min-70m/min). The published ranges of the ZT-76 and the ZT-60 overlap from 30 mm to 80 mm. The ZT-76 and the ZT-127 overlap from 32 mm to 90 mm.

Frequently asked questions
What pipe sizes can the ZT-76 produce?
The ZT-76 covers pipe ID 30 mm to 90 mm with a wall thickness of 1.0 mm to 4.0 mm, at line speeds of 15 to 70 m/min.
What units make up the ZT-76 line?
The line is listed as 7 units: double-head uncoiler, accumulator, forming, sink for cooling water, sizing line, computer controlled flying saw and rail type run out table.
How does the ZT-76 compare with the ZT-127?
The ZT-76 runs 30mm-90mm pipe at 15m/min-70m/min. The ZT-127 runs 32mm-127mm pipe at 20m/min-70m/min. They overlap between 32 mm and 90 mm, so where both cover the same pipe size the choice comes down to line speed and the equipment list rather than the pipe range.
