The brief introduction of main equipment

1. The Forming Machine

Our LSAW steel pipe forming machine adopts the CADMAN-CNC Number control system produced by LVD company,Belgium,and constituted with main machine, deliver roller, front and back feeding deliver, side ejection, mould, hydraulic system, and electronic control system.  It deliver feeding with continuous J-C-O technology by spinning pipe, and produce LSAW open pipe barred continuously and efficiently. It can automatically adjust rolling quality, rolling pressure and plate load according to different steel grade, wall thickness, plate width the meanwhile, the up the down molding has the deformation compensation function, which can avoid bad effect of transformation? For molding and promise the glancing flatness in overall length in the plate suppressing process.

2.the Plate Edge Milling Machine

Our LSAW steel is composed of reparation rack automatic centering device. Clamping car, milling unit, magnetic auto chip-removal machine, hydraulic pressure, lubrication and electronic control system, realizing the automatic control with the collecting machine, electricity and liquid. It makes a steel plate with the same on both sides of the groove shap and size to ensure the milling process parameters of the contant and the quality of qualitative milling which laysa good foundation for the product quality after welding process.

3 Tack Welding Machine

Our unit adopts principle of three-point jointing, main and assistant pressure head can make the after-molding pipe jointing and cent ring quickly and accurately, then wipe off welding seam mismatching.The main pressure head has concession function,can reduce pipe embryoerror,increase jointing power.And avoid convex defect of heavy diameter-thin  thickness pipe.It adopts welding seam continuous gas –protecting MAG and laser tracing equipment, and guarantees pre-welding quality,makes a good basis for inside and outside welding.

4.Inside welding and Outside Welding Equipment

The Inside welding and outside welding Equipment of Our LSAW steel pipe is constituted with PLC controlling system ,automatic wire facility, automatic tracing facility, welding gun regulation, soler automatic adding equipment etc.Welding head carry with groove duct which can clear welding seam rubbish,it can prevent rubbish influence for welding seam quality.At the same time,inside machine carry with the laser designator, the operator can observe welding seam location precisely to ensure welding quality.
