Black Oil HFI , HFW , ERW Steel Pipe use in the petroleum industries
ERW steel pipe is a straight seam electric resistance welded pipe, abbreviated as ERW pipe, which is a round pipe welded by steel plates. It is used to transport vapor and liquid objects such as oil and natural gas, and can meet various requirements of high and low pressure. At present, it plays an important role in the world of transportation pipes.
Electrical resistance welding will be welders parts formed pressed between two electrodes, and subjected to current, the resistor thermal effects generated by the current flowing through contact with the workpiece surface and the neighboring regions to be heated to melt the plastic state, so thatmetal-binding method. Resistance welding methods are mainly four kinds, namely, spot welding, seam welding, projection weldingfour main methods of resistance welding: point welding, seam welding, projection welding welding , butt welding.
