ⅠGeneral Introduction
This production line is for high frequency straight seam welded round pipe (Φ19～Φ60mm, δ0.9～1.6mm) and related square pipe, special section tube (δ≤1.2mm). The production line is composed of automatic rotary material rack to sized cutting saw. Also the production speed can be adjusted according to pipe diameter and thickness.
Ⅱ Pipe material:
1. Hot or cold rolling strip steel (In accordance with GB700-88 or GB1591-88).
2. Mild steel or low alloy steelδs≤345Mpa δb≤610Mpa
3. Strip steel thickness: 0.9～1.6mm (In accordance with GB708-88)
4. Strip steel width: 60～190mm
5. Inner diameter of steel strip coil:Φ350～Φ450mm
6. Outer diameter of steel strip coil: Φ600～1000mm
7. Weight of strip coil: ≤1000kg
Ⅲ Pipe range:
1. Diameter: Φ19～Φ60mm
2. Thickness: 0.9～1.6mm (square pipe or special section tube≤1.2mm)
3. Length: 4～8M
Ⅳ Production process:
Raw material- Material feeding - Shearing and butt welding - Material storing - Material flattening - Feeding - Roll forming - Seam direction guiding - Extruding - High frequency induction welding - Welding burr removing - Water cooling - Pipe shape and size adjusting - Computerized saw cutting - Pipe automatic unloading - Checking and collecting
Ⅴ Rolling speed: 40～90M/min
Ⅵ HF equipment power: 150KW
Ⅶ Items buyer should prepare (for advice)
