Embodiment Construction

[0040] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0041] Such as figure 1 as shown, figure 1 It is a schematic cross-sectional view of the composite reinforced wound pressure pipe along the radial direction. In this embodiment, the composite reinforced wound pressure pipe includes a plastic outer layer 10 , a plastic inner layer 30 and a long glass fiber sheet reinforced plastic layer 20 arranged between the plastic outer layer 10 and the plastic inner layer 30 . Wherein, the long-wave fiber sheet reinforced plastic layer 20 includes a long-wave fiber sheet 22 and a plastic composite layer 21 coverin...

Abstract

The invention relates to the technical field of plastic pressure pipes, in particular to a composite reinforced winding-type pressure pipe. The composite reinforced winding-type pressure pipe comprises an outer plastic layer, an inner plastic layer and a long glass fiber sheet reinforced plastic layer arranged between the outer plastic layer and the inner plastic layer. The long glass fiber sheet reinforced plastic layer comprises a long glass fiber sheet and a plastic composite layer wrapping the long glass fiber sheet, and the long glass fiber sheet is wound on the outer surface of the inner plastic layer through the wrapping plastic composite layer to form the long glass fiber sheet reinforced plastic layer; the long glass fiber sheet is composed of regularly-distributed long glass fibers, and the long glass fibers are flaky. The invention further discloses a forming method of the composite reinforced winding-type pressure pipe. Through the composite reinforced winding-type pressure pipe and the forming method of the composite reinforced winding-type pressure pipe, the process that the long glass fiber sheet is wrapped by the plastic composite layer and then wound on the outer surface of the inner plastic layer is simple, the production cost is low, and the yield is high. The pressure resistance is high, and the process stability is good. In addition, the long glass fibers are regularly distributed, so that the strength of the formed pressure pipe is uniform.

Description

technical field [0001] The invention relates to the technical field of plastic pressure pipes, in particular to a composite reinforced winding pressure pipe and a forming method thereof. Background technique [0002] Compared with traditional pressure pipes, large-diameter plastic pressure pipes have better hygienic performance and anti-seismic performance, and have better overall performance than traditional large-diameter pressure pipes (such as PCCP pipes or ductile iron pipes, etc.), so the manufacturing conforms to the application The required large-diameter plastic pressure pipe is a problem that those skilled in the art are trying to solve. [0003] At present, the use of winding and welding forming technology to manufacture large-diameter pressure-free plastic pipes has been popularized, and practice has proved that the winding and welding structure wall pipes manufactured in accordance with relevant standards are reliable in the field of non-pressure pipes such as b...
