High Performance Stainless Steel Tube Making Machine For Handrail BG114

Brief introduction and quotation of

BG114 high precision machine unit for stainless steel welded pipe

Description of product

Summary:

This equipment is specially used for producingΦ48-Φ114mm, δ1.0-3.0mm(Square and rectangle pipe≤2.5mm )stainless steel straight seam welded pipe. It made by refined materials in high precision and equipped with fixed length cutting saw. The main machine includs forming, welding ,sizing and straightening device. The composition of equipment is from uncoiler to fixed length-cutting saw. Rolling speed can be adjusted correspondingly within suitable range of pipe diameter and wall thickness.

Introduction of main components:

Uncoiler:

Structure type: Double-side 180orotary hydraulic expanding tightly, which insure steel coil feeding alternatively and make steel strip going into accumulator freely.

Applicable range: 150-360mm steel strip width, 1.0-3.0mm thickness,

Φ800-Φ1200mm steel coil O.D., Φ450-Φ550mm steel coil I.D., Max.3000kgs steel coil weight.

Feeding & leveling device:

Form: Up and down five rolls are passively leveled for straightening strip steel before it is fed into forming unit.

Forming device:

Mainly roughly mill-forming steel strip and controlling weld seam.

a. Horizontal roll stand:
