Description

technical field [0001] The present invention relates to the technical field of pipeline processing equipment, more specifically, it relates to an RTP pipeline winding equipment and a winding method thereof. Background technique [0002] Reinforced thermoplastic pipe, referred to as RTP, mostly adopts a three-layer structure, the inner layer is a thermoplastic pipe, the middle layer is a reinforcement layer for reinforcement, and the outer layer is an outer coating layer for protection. RTP pipes have been used in high-pressure natural gas transportation. , Submarine water transfer and other fields are widely used. [0003] RTP pipe winding equipment is a special equipment for the production of RTP pipes. Currently, the winding equipment on the market usually uses a single heating method to make the strip and the pipe fit together, but the single heating method requires a higher temperature heating device to achieve instant heating on the outer wall of the pipe. Heating, the...

[0003] RTP pipe winding equipment is a special equipment for the production of RTP pipes. Currently, the winding equipment on the market usually uses a single heating method to make the strip and the pipe fit together, but the single heating method requires a higher temperature heating device to achieve instant heating on the outer wall of the pipe. Heating, the pipe will encounter a large difference between cold and heat in an instant, and the pipe will easily deform due to thermal expansion and contraction, which will affect the structure of the pipe itself, and will cause uneven bonding between the strip and the pipe, and poor winding tightness, eventually causing The pressure bearing capacity of the produced RTP pipeline is reduced
