Pipe expanding machine is a professional equipment for expanding and rounding the end of spiral submerged arc welded steel pipe, mainly used in oil and gas and fluid transmission pipelines to help pipe expanding and rounding. And the pipe end expanding machine has the characteristics of high efficiency, compact structure, high strength and good stability, suitable for the place with high processing accuracy requirements.
Pipe end expanding machine belongs to the metal welded pipe shaping equipment, it is a cone expansion head, expansion in the steel pipe, to eliminate the forming pressure and welding stress of the steel pipe, and ensure that the diameter of the welded pipe end is consistent. The pipe expanding machine is composed of a trolley, an expander, a working sleeve, a fixed seat, an oil cylinder, a lubricating station, a bench, a hydraulic station and an electronic control system. The expander is arranged in the trolley, the expander is connected to the oil cylinder by a working sleeve, and the expander is composed of an expansion head, an expansion block, a guide disk, a pull rod, etc. It is a large equipment of steel pipe testing & expanding machine to ensure the shape diameter of straight seam metal welded pipe and eliminate stress through the segmented mechanical extrusion process.
