Abstract

The invention relates to the technical field of manufacturing of thermoplastic composite pipelines, in particular to a large-caliber thermoplastic composite long-distance transportation pipe manufactured through a 3D printing forming technology and a manufacturing method and device of the large-caliber thermoplastic composite long-distance transportation pipe. The large-caliber thermoplastic composite long-distance transportation pipe structurally and sequentially comprises a lining layer, a fiber reinforced layer and an outer protective layer from inside to outside. The length of the thermoplastic composite long-distance transportation pipe is 8-10 m, the pipe diameter of the thermoplastic composite long-distance transportation pipe is 1000-1500 mm, the lining layer is 10-50 mm thick, the reinforced layer is 50-200 mm thick and the outer protective layer is 10-50 mm thick. The large-caliber thermoplastic composite long-distance transportation pipe has the outstanding advantages of being light in weight, resistant to high temperature, resistant to corrosion, good in flexibility and air impermeability, high in internal and external pressure rating, convenient to install and the like. Because of the smooth inner wall, the large caliber and the high internal and external pressure rating, the large-caliber thermoplastic composite long-distance transportation pipe can obtain a higher fluid speed and a higher fluid flow and is particularly suitable for being applied on the aspect of long-distance oil and gas transportation pipelines.

Description

[0001] Technical field: [0002] The invention relates to the technical field of thermoplastic composite material pipeline manufacturing, in particular to a large-diameter thermoplastic composite material fiber reinforced long-distance pipeline prepared by using 3D printing technology and its manufacturing method and device. [0003] Background technique: [0004] For the oil and gas industry, pipeline transportation is currently the safest, most economical and least environmentally damaging transportation method. Most of the material transportation in oil and gas fields is carried by long-distance pressure pipelines. Such pipelines usually need to withstand high pressure or complex loads and harsh working environments. With the continuous increase of oil and gas consumption, in order to improve the transmission efficiency, large-diameter (above 600mm), high-pressure (above 5MPa) transmission technology has become the trend and direction of long-distance pipelines. This puts ...
