Blow molding equipment unit: 1. Overview: (1) production diameter range 8-55mm (2) production speed 10-20m / min (3) raw materials PE, PP corrugated pipe production line, PVC MPP corrugated pipe production line, PA2. Extruder: (1) vacuum drying hopper feeder + (2) Screw diameter: 50mm nitriding treatment (3) barrel: electric heating, air cooling (4) Temperature area: 4 area (5) Gearbox: gear hard surface treatment (6) Motor 11kw, frequency control 3. extruder head: 4 Bellows forming machine: (5 Winder: (1) income reel: diameter 800mm (2) diameter range: diameter 8-55mm (3) winding speed: 30m / min (4) Motor power: 1.1kw PVC single wall corrugated pipe is PVC as the main raw material, extrusion blow molding, it is foreign 1970s development up of new products .PVC single wall corrugated pipe use structure its annular groove, it can both rigid and rigid pvc pipe flexible hose, so the tube has just the soft features corrugated pipe production equipment, can be used for transport of certain liquids and gases as well as embedded wire casing inner single-wall corrugated pipe, the outer surface are corrugated, bending resistance, flexibility, although excellent, but the fluid resistance, and easy to make the inner surface of the groove produced at deposition of suspended solids, so PVC single wall corrugated pipe, mostly thin-walled, high strength requirements without the need to bend freely and small diameter tube, such as threading pipe, drain water pipes, exhaust pipes, etc. single wall corrugated pipe inner diameter or outer diameter of the basic structural parameters, such as mobile phones other wall thickness, pitch, and so are the wave thick inner or outer diameter as a reference to determine the corrugated highly available coefficient K expressed deep wave, which is the ratio of outer and inner diameter of the bellows , the greater its value, the higher the altitude corrugated bellows waveform, according to the geometry of the axial cut after the spiral can be divided, U-shaped, C-shaped, S-shaped, V-shaped and Ω-shaped double-wall corrugated pipe production line, wave on the tube stiffness and strength have a certain influence. The main difference between P VC single wall corrugated pipe and PVC pipe production technology in general after its circular cross-section tube extrusion, blow in hot corrugated mold molded bellows, the process described later see, the production process and forming principle corrugated pipe production equipment |. corrugated pipe production line | day Nobuyasu provide Qingdao days Nobuyasu Plastics Machinery Qingdao day letter Thai Plastic Machinery Co., Ltd.
