The ZT-127 covers pipe ID from 32mm-127mm, in wall thickness from 1.5mm-4.0mm, at line speeds of 20m/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-127 sits in the range
Published range for the ZT-127: 32mm-127mm pipe, 1.5mm-4.0mm wall, 20m/min-70m/min. In the eight-model range it sits between the ZT-76 (30mm-90mm, 15m/min-70m/min) and the ZT-165 (50mm-165mm, 30m/min-50m/min). The published ranges of the ZT-127 and the ZT-76 overlap from 32 mm to 90 mm. The ZT-127 and the ZT-165 overlap from 50 mm to 127 mm.

Frequently asked questions
What pipe sizes can the ZT-127 produce?
The ZT-127 covers pipe ID 32 mm to 127 mm with a wall thickness of 1.5 mm to 4.0 mm, at line speeds of 20 to 70 m/min.
What units make up the ZT-127 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-127 compare with the ZT-165?
The ZT-127 runs 32mm-127mm pipe at 20m/min-70m/min. The ZT-165 runs 50mm-165mm pipe at 30m/min-50m/min. They overlap between 50 mm and 127 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.
