Introduction of PE hollow wall winding pipe equipmentIntroduction of PE hollow wall winding pipe equipment
PE hollow wall winding pipe equipment is a new product that replaces the metal protective spring used for maintenance of the rapid-entry hose. The surrounding tube is generally made of nylon material or polypropylene material. Corresponding to the traditional metal spring protection product, the surrounding tube has good wear resistance, anti-aging and anti-corrosion functions; it can more effectively perform anti-aging and anti-friction maintenance on the outer surface of the hose. Compared with rubber hose spring protection products and other sheath products, the surrounding tube has better convenience and environmental protection and energy saving effects. The inner and outer surfaces of the surrounding pipe are generally flat, and the outer surface is divided into two types: flat and curved. There are also pe winding pipe equipment, hollow wall winding pipe equipment and hollow wall plastic steel winding pipe.
One-time shaping process of PE hollow-wall winding pipe equipment: nylon or plastic pellets are heated and plasticized by a plastic extruder to be extruded into thin strips. The strips are extruded from the die of the machine head and surround the surrounding machine clamp without cooling by water. It is formed into a spiral sheath after being separated from the core rod after cooling and shaping by cooling water. Secondary molding process: Nylon or plastic pellets are extruded through the extruder and then enter the cooling water for cooling; the cooled strips are then looped around the mandrel of different standards by the winding machine; then the mandrel is pushed into the vulcanizing tank Heat vulcanization.
