Description

Technical Field

[0001] The present invention belongs to the field of composite material repair, and more specifically, relates to a pipeline winding device and a repair method thereof. Background Art

[0002] As the development of oil and gas fields enters the middle and late stages, the aging problem of pipeline systems has become increasingly serious, and defects such as corrosion, cracks, and deformation occur frequently, seriously threatening the safe operation of pipelines. Traditional pipeline repair methods such as replacing pipe sections and welding repair have disadvantages such as high cost, long construction period, and great impact on pipeline operation. Therefore, it is particularly important to develop a repair technology that is efficient, economical, and has little impact on pipeline operation. Composites are composed of reinforcing fibers and resin matrices, and have advantages such as high strength, high modulus, corrosion resistance, and light weight, and have been widely used in fields such as aerospace and automotive manufacturing. In recent years, with the continuous development of composite material technology, its application in the field of pipeline repair has gradually attracted attention.

[0003] Currently, the composite material pipeline repair device still generally adopts the manual winding process, and there are significant technical bottlenecks in actual engineering applications. First of all, under the manual operation mode, a large number of construction personnel need to be invested, forming a high-density labor force dependence, which not only significantly increases the labor cost, but also leads to insufficient process stability due to individual differences in the skill levels of operators. The specific manifestations are as follows: (1) The discreteness of process parameter control is large, and it is difficult to ensure the uniformity of the winding layer tension and the consistency of fiber orientation, directly affecting the mechanical properties of the composite layer; (2) The operators are in a state of high-intensity physical labor for a long time, which is prone to the accumulation of construction errors and increases the defect rate of the repaired structure (the typical manifestations are local debonding, fiber wrinkles, etc.); (3) In a confined space or a high-risk environment (such as the repair scenario of submarine pipelines), manual operation faces prominent safety hazards and limited operation windows.
