[0033] Examples:
[0034] The production process of the RTP tube of the present invention includes the following steps:
[0035] 1) Send the granular PE to the hopper of the extruder 1 with negative pressure;
[0036] 2) The first extruder 1 heats the PE plastic and continuously extrudes it through the die at a higher pressure;
[0037] 3) The melted PE passes through the vacuum sizing sleeve of the vacuum water tank 2, and is water-cooled in negative pressure to form a PE inner tube;
[0038] 4) The PE inner pipe continues to be cooled and formed in the spray water tank 3;
[0039] 5) The first air cooler 4 blows dry the surface of the PE inner pipe taken out of the spray water tank;
[0040] 6) Traction machine 5 continuously and stably hauls the PE inner tube to provide the power for forming the PE inner tube;
[0041] 7) The winding machine 6 winds the plastic-coated reinforcing tape made of steel wire or fiber yarn into a rope with constant tension in opposite directions on t...
