These machines are used to straighten and repair bent or deformed steel pipes produced during construction. After straightening, the pipe surface is free of indentations and diameter reduction, meeting the Ministry of Construction standard (bending degree less than one-thousandth per meter). Steel pipe straightening machines are ideal for construction companies, steel pipe rental companies, and scaffolding construction units. The machine consists of a straightening system, a rust removal machine, and a painting box, all tightly integrated. It can straighten pipes individually or perform both straightening and rust removal simultaneously. Painting and marking of the pipes can also be done concurrently. It features a standard 4kW motor output for stable and efficient power; the mechanical rollers (high-temperature quenched) provide durable straightening.
