Problems solved by technology

[0004] Since the axial strength and hoop strength of FRP pipes are formed by glass fibers arranged axially, circumferentially or at a certain angle, the circumferential winding without axially arranged fibers can increase the hoop strength. In addition, the cross-wound fibers also have a certain angle with the axial direction. However, the fibers cannot bear the linear tension and cannot directly increase the axial strength; In the case where the circumferential winding thickness of the end is large and the thickness of the middle part is small, the hoop strength is not uniform

Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the examples.

[0026] A kind of FRP pipeline production process of the present invention, described FRP pipeline is formed outside the FRP mandrel, comprises the following steps:

[0027] S0: FRP mandrel preparation: The FRP mandrel is connected with a driving device that drives it to rotate along the axial direction, as long as it can achieve uniform rotation. During the laying process of each fiber layer, the FRP mandrel is in a state of uniform rotation.

[0028] Base layer preparation: Spray wear-resistant resin evenly on the surface of the FRP mandrel.

[0029] Reinforcement fiber preparation: Arrange the reinforcement fibers neatly on both sides of the axis direction of the FRP mandrel. When arranging, the fiber creel can be used for placement, and the fiber creel slides along the axis parallel to the FRP mandrel.

[0030] Preparation of resin glue: choose resin glue with pouring mechan...

Abstract

The invention relates to the technical field of glass fiber reinforced plastic pipeline manufacturing, in particular to a glass fiber reinforced plastic pipeline production process. The method specifically comprises the following steps: weaving, winding and laying a lining layer, an internal winding layer, an external winding layer and an external protection layer in the glass fiber reinforced plastic pipeline by adopting reinforced fibers soaked with a resin glue solution, and carrying out extrusion forming and heating curing on a pipeline fiber laying layer, so as to obtain the glass fiber reinforced plastic pipeline. By limiting the weaving and winding mode, angle and path of each fiber laying layer in the glass fiber reinforced plastic pipeline and parameters among the reinforced fibers, continuous winding of the winding fibers in the axial direction, the circumferential direction and the angle crossing direction of the pipeline is achieved, and the glass fiber reinforced plastic pipeline has high circumferential strength and axial strength.

Description

technical field [0001] The invention relates to the technical field of FRP pipe manufacturing, in particular to a FRP pipe production process. Background technique [0002] FRP pipe is a lightweight, high-strength, corrosion-resistant non-metallic pipe. Compared with ordinary steel pipes, it has the advantages of long service life, low overall cost, quick installation, safety and reliability, and is widely used in petroleum, chemical and drainage industries. [0003] FRP pipes are made by pre-impregnating glass fibers with unsaturated resin and winding them in multiple layers on the surface of the mold. The commonly used winding system at present is to use the winding device on the driving part which is arranged on the workbench and can move along the length of the workbench to introduce the resin-impregnated glass fiber from the tangential direction of the lower part of the FRP pipe mold rotating towards the workbench. , and make it wrap layer by layer on the surface of t...
