1.3 Dimension range of processing steel pipe:

(1) O.D.: Φ25-Φ80mm 20*20-40*80

(2) Wall thickness: 1.5-4.0mm(square pipe and special-shaped pipeδ≤3.2mm)

(3) Length: 4-10m

1.4 Product (steel pipe) process flow:

Raw material (steel coil) → uncoiling → shearing and end welding → material accumulating → non-power leveling → mill-forming → high-frequency welding → removing burrs outside of weld seam → cooling → sizing → roughly straightening → fixed length cutting → finished pipe → conveying finished pipe pass for rolls.

2. Introduction of main facilities:

2.1 Decoiler

Structure type: pinching and

putting raw material with double-drill structure, which ensures steelcoil feeding alternatively and make steel strip going into accumulator freely.

Applicable range: 100-245mm steel

strip width, 1.5-4.0mm thickness,

Φ1000-Φ1500mm steel coil O.D.,

Φ500-Φ650mm steel coil I.D.,

Max. ≤2500kg steel coil weight.

2.2 Shearing and welding machine, which ensures double steel coil shearing tidily and then welding together and leveling weld seam. Automatic shearing and manual welding are adopted.

 

2.3 Accumulator:The accumulator is a strip storing unit in the longitudinally welded pipe andformed section production. It stores certain amount of strip and leaves timefor the shear welder to shear and seld the ends to the strips. The uninterrupted fluent production is thus guaranteed. It's one of the main machines in the modern pipe mill line and formed section line.
