1. Output: 100-250kg/h 2. Production Speed: 3-12m/min 3. Pipe specification: OD/ID 32/26, 34/28, 40/33, 46/38.50/42, 63/54mm(according to you condition) The total line comprises three sets of extruders, co-extrusion mould, vaccum calibration spray tank, spray cooling water tank, haul-off, winder, printer(option). The main machine adopts screws specially used for polyolefin. Equipped with auto vacuum loader and auto constant temperature dryer and hopper, it possesses features of high production, good plasticization and stable extruding. The first extruder is for HDPE pipe extrusion, the second one is for inner silicon layer and the third one is for mark line. Die heads of helical type and basket type are perfect for polyolefin, and can help to produce sound melting pressure, and improve the plasticization capacity. Meanwhile, stable material-flow and pressure grade can be guaranteed. Advanced vacuum calibrating method improves the cleanliness and hardness of surface. Reasonable high-speed sprinkling cooling water tank guarantees the pipe quality and high speed stable extruding. Caterpiller of the hauling machine adopts anti abrasion alloy material, which realizes stable traction, wide frequency adjustment range and long lifespan.
