Abstract

The invention provides a glass fiber reinforced plastic reinforced metal pipeline, relating to the technical field of glass fiber reinforced plastic pipelines. According to the technical scheme, the glass fiber reinforced plastic reinforced metal pipeline comprises an inner pipe, two joints respectively arranged on the outer walls of the two ends of the inner pipe, and a reinforcing layer arrangedon the outer surface of the inner pipe, wherein a connecting part is arranged at one end, facing towards the reinforcing layer, of each joint; the connecting part extends to the position between theinner pipe and the reinforcing layer; and at least one protruding structure used for reinforcing connection between the connecting part and the reinforcing layer is arranged at the position, connectedto the reinforcing layer, of the connecting part. The connecting part and the protruding structure enhance the connection between the joint and the reinforcing layer; and the protruding structure enables a staggered meshing structure to be formed between the connecting part and the reinforcing layer, so that the reinforcing layer can share a part of pipeline tension, and the overall tensile strength of the pipeline is enhanced.

Description

technical field [0001] The invention relates to the technical field of FRP pipelines, in particular to a FRP reinforced metal pipeline. Background technique [0002] The stainless steel pipe reinforced with FRP has the advantages of FRP sand pipe and stainless steel pipe: corrosion resistance, high temperature resistance, low thermal conductivity, good thermal insulation performance, both rigidity and toughness, lighter weight, and higher comprehensive cost performance. A new reinforced metal composite pipe. However, the stainless steel inner tube in this kind of pipeline is relatively thin, and the tensile force of the pipeline basically acts on the stainless steel inner tube. The connection between the glass fiber reinforced plastic layer and the stainless steel inner tube and the joints at both ends is not close enough, and the pullout resistance is poor. Contents of the invention [0003] Aiming at the problem of poor pull-out resistance in the prior art solutions, th...
