The vertical steel pipe straightening machine is a metallurgical device used to straighten metal profiles, bars, pipes, wires, and so on. The main types include pressure straightening machines, balanced roller straightening machines, and inclined roller straightening equipment. The machine features a vertical setup with bidirectional drive, equipped with two sets of staggered straightening rollers that squeeze the steel pipe. Through changes in angles, the pipe undergoes continuous elastic deformation to correct bending defects. Standard models can achieve a straightening accuracy of up to ≤0.3mm/m.
Our ACA group, can customize the machines based on the user's required pipe diameter range and straightening accuracy, configuring different numbers of rollers and conveyor systems. The straightened pipes can achieve a linear accuracy of less than 1.5mm.
For example, ACA's fully automatic vertical straightening machine comes with a seven or ten-roller setup, can straighten at speeds up to 30m/min, and handle steel pipes with a maximum diameter of Φ920mm and a wall thickness of 80mm. After straightening, the pipe's local bend per meter is less than 1.5mm and the total bend of the pipe does not exceed 0.15% of its length. It uses PLC intelligent control.

Welded steel pipes are made by bending steel plates or steel strips into shape and then connecting the seams using welding. According to the welding method and usage, they can be divided into the following three types: I. ERW (Electric Resistance Welded) Steel Pipe and Tube Mill II. Spiral Welded Steel Pipe (SSAW Tube Mill) III. Other special welded steel pipes Line
Recently, the large oil and gas pipeline bending machines was made by ACA group, After on-site inspection and approval by Kazakh technicians, the pipe bender equipment was loaded and shipped to Kazakhstan.
The challenges in large-diameter longitudinal seam welded pipe production lines mainly focus on four core areas: Steel plate forming, welding, finishing, and inspection. Below, we will mainly introduce our ACA- LSAW (Longitudinal Submerged Arc Welded) pipe production line’s forming methods and technical challenges.
High-Speed & High-end ERW pipe equipment is a professional set of machinery used to produce straight seam welded pipes through high-frequency resistance welding. Take its high-precision forming and efficient welding features, ERW/HF welded tube widely applied in industries such as oil and gas transportation, municipal pipelines, and building structures.
The inner wall of the steel pipe, after shot blasting, is coated with anti-corrosion powder using an internal spraying system through hot-melt spraying. This coating machine is specialized for internal epoxy powder anti-corrosion spraying of steel pipes, mainly used for pipeline anti-corrosion processing in the petroleum, water conservancy, and municipal fields. This internal pipe spraying anti-corrosion equipment mainly includes: mobile flat car, cantilever spray rod, internal spray gun, two-component spraying system, medium-frequency heating, dust collection and recovery system, and pipe end recovery dust removal equipment.
The Anti-Corrosion Coating processing production line is used to make two layer FBE, two layer PE, three layer PE (3PE), TPEP Two layer epoxy powder coated on external steel pipe (⌀57-1220mm).
