erw pipe making machine
It is a sophisticated piece of equipment especially designed for electric resistance welded pipes in high volume production. Its functions include collecting and forming the coil of metal into a continuous pipe, and using an electric process (ERW) welding that seam together.The main functions of the erw pipe making machine are feeding and shaping the metal coil into a continuous pipe assembly, welding the seam of the pipe by electric resistance so tightly that some material is squeezed out through pores, and shearing off that unnecessary material. The secondary function includes punching or forming different profile tubing with rollers.The machines primary functions are feed rolls for sheet coils, various sets of shaped rollers on roller holders which give precise control over shapes imparted to the fabricated pipe (a shaft cutting operation), pipe delivery and welded seam forming lines each with their own line sensor.Technical features include complete set automatic control system, precision roller displacement, converter speed changing drive which ensures even wall thicknesses of pipes made up from metal pipes cut into desired pieces by roll shears.The erw pipe making machine is widely used in the construction, automobile and manufacturing industries to produce piping for all sorts of purposes. Examples are bicycles, cars and refrigerators. Over the past 10 years it has been much used in manufacture of materials suited to large-scale piping that will be demanded in tomorrow's environmentally aware society (such as water supply pipes for buildings)."
