HF Straight Seam OD 76-165mm ERW Tube Mill Welded Pipe Machine ERW165

Straight Seam Hollow Section Pipe Making Machine HF Welded Pipe Machinery ERW Tube Mill

Product Details

Automatic High Frequency Straight Seam ERW Carbon Steel Pipe Mill is specially used for producing high-frequency straight seam welded pipe and corresponding square pipe and special-shaped pipe . 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.

Machine Parts

1. uncoiler

Function: 360ºrotary hydraulic-pressure expanding tight, which insure steel coil feeding alternatively and make steel strip go into accumulator freely.

2. accumulator

Overview: it has two kinds of accumulator for optional.

usually big line use horizontal type, and small line use vertical type.

Forming part:Mainly roughly mill-forming steel strip and controlling weld seam

3. Sizing part

Function: Mainly fine shaping pipe after welding and controlling size accuracy.

4. Turkey's head

Function: It is mainly used for straightening of finished pipe roughly online.

5. Computer-controlled tracking cutting saw

If need better precision for the tube cutting, could choose cold saw cutting as optional.

Cold sawing cutting

Digitally cold cutting machine is composed of mechnical parts, electronic parts and hydraulic parts. Three shafts are tracking shaft, cutting feeding shaft, saw blades rotating shaft, this three shafts are controlled by its special motion controller, servo motor driving operatiing, and the parameters are entered through LCD touch screen, also working condition can be visible checked from touch screen. The saw blades of cold saw using the high speed steel, and the cold saw can run synchronous while the pipe mill line producing; the CNC system of the cold saw can ensure the cutting speed and position accuracy, the cutting head(with saw blade) feeding and rotating speed can be adjusted by CNC program according to the technological requirements.

6. Rollers

Rolls for welded pipe will be ordered additionally according to type and specification provided by customer. Material: Cr12
