Technical Specifications

Key Features and Machine Components

The production line is composed of several critical units, each engineered for precision and durability. The auxiliary machine includes a single-station manual uncoiler, shearing and welding system, and a four-roller delivery machine. The uncoiler accommodates steel strip coils with an inner diameter of Ф762 mm and an outer diameter of Ф1800 mm, ensuring seamless material feeding. The shearing and welding process utilizes hydraulic cutting and manual welding (excluding automated welding machines), while the four-roller delivery machine maintains raw material supply for continuous operation.

The main machine features a seven-roller leveling system, forming and sizing units, and a cooling water tank. The horizontal shaft (Ф100 mm) and vertical roller shaft (Ф60 mm) are constructed from 40Cr steel, hardened for longevity. The extrusion roller shaft (Ф70 mm) also uses 40Cr material, ensuring robust performance. The gear box employs ZG35# spiral bevel gears with a module of m=12, made from 20CrMnTi for enhanced load capacity.

Advanced Cutting and Straightening System

The computer flying saw machine is a cornerstone of the production line, capable of cutting pipes with a diameter of Ф76–89 mm and wall thickness of 2.0–5.0 mm. It operates at a maximum speed of 80 m/min, with a saw blade size of Ф900 mm and a trolley travel distance of 2 m. The system’s precision ensures a fixed length accuracy of ±3 mm, meeting stringent industry standards.

The straightening machine eliminates residual stress and bending in the welded pipes. It features a four-column frame with upper and lower rollers, with the lower roller acting as the active component. The straightening rollers (Ф220×400 mm for upper, Ф200×240 mm for lower) are made from GCr15 steel (HRC 60–65), ensuring consistent quality. The machine operates at a speed of 100 m/min, suitable for pipes with diameters of φ60–φ89 mm and wall thicknesses of 2.0–5.0 mm.

Applications and Industry Relevance

This production line is ideal for manufacturing line pipe steel and welded gas pipe, which are critical in infrastructure projects, pipeline networks, and industrial equipment. Its ability to produce high-quality, consistent pipes makes it a preferred choice for linepipe and steel pipe line applications. The system’s efficiency and adaptability align with the demands of modern manufacturing, as highlighted in NIST’s research on industrial automation and material standards (National Institute of Standards and Technology (NIST)).
