System Composition and Functionality

The production line comprises several critical components, each designed to optimize the manufacturing process:

1. Auxiliary Machine Components

• Single-Station Manual Uncoiler: Adapts to steel strip coils with an inner diameter of Φ762 mm and outer diameter of Φ1800 mm. It ensures smooth material feeding with a belt width of 280 mm and a weight capacity of 5 tons.
• Shearing and Welding Unit: Features hydraulic cutting, pneumatic pressing platforms, and manual welding (excluding welding machines) for precise edge preparation and joining.
• Four-Roller Delivery Machine: Maintains a steady supply of raw materials while delivering welded steel strips to the storage bin. It includes a gantry frame, upper and lower roller transmission, and a gear split axle box for enhanced stability.

2. Main Machine Components

• Forming and Sizing Unit: Utilizes a seven-roller leveling system, seven flat and eight vertical forming rollers, and six flat and six vertical sizing rollers to achieve precise pipe geometry. The system includes a Turkish ear head (8 rollers, single-sided 4 rollers) for enhanced shaping.
• Extrusion and Scraping Mechanism: Ensures uniform wall thickness and surface quality by applying controlled pressure to the welded seam.
• Cooling Water Tank: Rapidly cools the steel pipe to maintain structural integrity and prevent deformation.
• Computer Flying Saw: Cuts pipes to fixed lengths with an accuracy of ±3 mm. It features a 55KW AC sawing motor and a 22KW DC driving motor, capable of 15 cuts per minute.

Applications and Industry Relevance

This production line is ideal for manufacturing line pipe steel and welded gas pipe for diverse applications:

• Construction Industry: Used for scaffolding, structural supports, and HVAC systems.
• Oil and Gas Sector: Produces pipes for pipelines, storage tanks, and drilling equipment.
