ERW Tube Mill Description
ERW pipe mill is suitable for all kinds of round pipe, square pipe and rectangular pipe. The required equipment and functions depend on the pipe type and sizes intended for production.
ERW Tube Mill Classification
According to the product functions, ERW pipe mill can be divided into API model and national standard model. API model mainly produces high level steel pipes, such as delivery pipe of petroleum, natural gas and oil well casing. National standard model mainly produces the steel pipe, such as water-gas pipe and structure pipe.
ERW steel pipe production line: At first, the coil is loaded at the uncoiler, then but-welding the ends of coil, delivering to accumulator. After accumulator, the strip is pulled from accumulator contentiously by fixed speed, is formed to opened-pipe at forming machine, then welded by High frequency welder, deburred, cooled, shaped and sized as round pipe and rectangular&square pipe at the sizing area. Then the sized pipe is straightened after Turkey-head device and then cutt to fixed length by flying saw. At last, the fixed pipe is delivered from run-out table and inspected at the table.
This line could produce the round pipe, the rectangular and square pipe by material of cold/hot-rolled coil etc. It could be used at the metallurgy, construction, transportation, machinery, automobile industry. Adopting “W” forming type, it could make much more reasonable force, and much more perfect forming shape at each stand etc.
