The ZT-165 covers pipe ID from 50mm-165mm, in wall thickness from 2.0mm-5.0mm, at line speeds of 30m/min-50m/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-165 sits in the range
Published range for the ZT-165: 50mm-165mm pipe, 2.0mm-5.0mm wall, 30m/min-50m/min. It is the largest model in the range; the size below it is the ZT-127 (32mm-127mm, 20m/min-70m/min). The published ranges of the ZT-165 and the ZT-127 overlap from 50 mm to 127 mm.

Frequently asked questions
What pipe sizes can the ZT-165 produce?
The ZT-165 covers pipe ID 50 mm to 165 mm with a wall thickness of 2.0 mm to 5.0 mm, at line speeds of 30 to 50 m/min.
What units make up the ZT-165 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-165 compare with the ZT-127?
The ZT-165 runs 50mm-165mm pipe at 30m/min-50m/min. The ZT-127 runs 32mm-127mm pipe at 20m/min-70m/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.
