Φ101.6-355mm Pipe Straightener (Wall to 14mm, ≤1mm/m) | Teneng, Shijiazhuang, China

The Φ101.6-Φ355×14mm Pipe Straightener straightens round steel pipe after it comes off a tube mill. It handles pipe from Φ101.6mm to Φ355mm in diameter with wall thicknesses from 3mm to 14mm, and pipe lengths from 6 to 12m. The main transmission is driven by an AC motor.

It accepts pipe with an original curvature of up to 5mm per metre and straightens it to a precision of 1mm per metre or better. Teneng lists the line speed at up to 30m/min and notes that the pipe ends are not left with a special bend, which is a common problem with straighteners that can't grip the pipe head properly.

It is listed in Teneng's auxiliary equipment range, so it fits after a tube mill in a complete pipe production line. Steel grades listed are Q235, Q355B, and X70.

Why Choose a Dedicated Pipe Straightener?

Welded pipe tends to bow slightly after forming and welding, and heavy-wall pipe is harder to straighten in-line. A separate straightener corrects it before pipe goes to inspection, packing, or customers with tight straightness requirements.

• Wide size range. Φ101.6 to Φ355mm and up to 14mm walls, covering most of Teneng's tube mills up to the ERW325.
• Defined precision. 1mm per metre or better, from pipe with up to 5mm per metre of bow.
• Long pipe. Handles pipe lengths of 6 to 12m.
• High-strength steels. Suitable for Q235, Q355B, and X70.
• Standard drive. Main transmission uses an AC motor.

Frequently Asked Questions

What sizes of pipe can it straighten?
Round pipe from Φ101.6mm to Φ355mm, with walls from 3mm to 14mm and lengths from 6 to 12m.

How straight is the result?
1mm per metre or better, from pipe with an original curvature of up to 5mm per metre.

How fast does it run?
Up to 30m/min line speed.

What steel can it handle?
Q235, Q355B, and X70.

What drives it?
An AC motor drives the main transmission.

Is it made for a particular tube mill?
It's listed as an auxiliary machine, so it can be added to Teneng's pipe lines, but the page doesn't limit it to a particular mill.

What are the shipping and payment terms?
EXW, FOB, CNF, or CIF from Xingang Port, with payment by T/T or LC.

Is financing or staged payment available?
Yes. A deposit secures your order and begins production, with the remaining balance due only once your machine has been built, inspected, and is ready to ship.

Should I buy new or used?
This machine is available new, built to order.
