LSAW pipe machine
1. The production process is flexible, and the production efficiency is lower than that of HF ERW tube and Spiral welded steel pipe.
2. It can produce the pipe which is HF ERW tube mill, spiral pipe mill, even seamless steel pipe mill can not produce.
3. The production cost of LSAW pipe is higher than that of HF ERW tube and Spiral pipe, but there is a large discount space compared with seamless steel pipe.
4. It can produce the material and thickness which HF ERW tube mill and Spiral pipe mill can not produce.
5. It has been widely used in domestic heavy steel structure engineering and fluid pipeline engineering, foundation piling engineering.
Production technology process
CNC cutting → Steel plate UT → Edge miller → Surface cleaning → Plate edge pre-bending machine → JCO Forming machine → Pipe linking machine → Tack welding → Internal welding → Flux slag removal → External welding → Pipe repair welding platform → Guide arc plate cutting → Sizing machine → Straightener → Pipe UT → X ray tester → Internal and external welding seam grinding machine → Pipe expanding machine → Pipe end fire cutting → Hydro-tester → Beveling machine → Pipe end X-ray filming machine → Weighting and length measure → Marking → Store
