Knowledge about large diameter coiled pipe equipment

Large diameter winding pipe equipment is advanced in design and rigorous in workmanship. The single-screw extruder is selected, and it cooperates with foreign advanced gearboxes, with low energy consumption and high output value. PLC intelligent control is adopted, which is stable and reliable, and has a high degree of automation. A unique plastic-steel composite technology has been developed, the strip and pipe are produced at the same time, and the steel strip is composited in HDPE, without bubbles, without falling off, and without being corroded by other media. It is equipped with an independently developed compatible surround cage, which has strong compatibility, fast production speed of large-diameter pipes, and stable quality. Two production lines can cover the production of a full range of pipes with a diameter of DN200-DN3000.

The plastic-steel composite strip production line consists of belt hanging machine, shearing welding machine, belt storage machine, straightening machine, high frequency heating mechanism, single screw extruder, strip operation control cabinet, strip extrusion die, strip shaping die , stereotypes, traction machine composition.

The pipe wrapping production line is composed of a pipe operation control cabinet, a welding rod extruder, a hot air gun heater, a belt feeder, a wrapping cage, a pipe cutting saw, and a pipe conveyor.

The plastic-steel composite strip adopts a single-stage extruder molding production process, so that the steel strip enters the strip extrusion die of the single-screw extruder after being flattened, rust-removed and high-frequency heating by the straightening machine. The structural composite of the two materials is completed, and the strip is formed after being shaped by a strip shaping die and a shaping table, and cooled, and the strip is formed into a pipe by wrapping. The composite-molded plastic-steel surrounding pipe has the characteristics of stable structure and size, and even and flat coating.
