Production equipment of reinforced and toughened composite pipe

Abstract

The invention provides production equipment for a reinforced and toughened composite pipe, and belongs to the technical field of composite pipelines. The problem that in the prior art, a composite pipeline is low in strength is solved. The production equipment of the reinforced and toughened composite pipe comprises an extruder, a forming die, a core pipe communicated with the extruder, an outer pipe arranged outside the core pipe in a sleeving mode and a winding machine capable of wrapping reinforced fibers on the peripheral wall of the outer pipe, and a forming cavity channel is formed between a core die of the forming die and an outer die sleeve. The outlet end of the core pipe extends into the forming mold and communicates with a forming cavity channel of the forming mold, one end of the outer pipe is connected with the forming mold, and the reinforced fiber layer on the peripheral wall of the outer pipe can penetrate through the forming cavity channel. The composite pipeline produced by the production equipment has the advantages of high strength and good toughness.

Description

technical field [0001] The invention belongs to the technical field of composite pipes, and relates to production equipment for reinforced and toughened composite pipes. Background technique [0002] With the continuous expansion of cities and the continuous extraction of oil and natural gas, the demand for transportation pipelines is also increasing. Traditional steel pipes have poor corrosion resistance and are not easy to handle, so they can no longer meet the current needs. At the same time, my country's main oil and natural gas are mostly distributed in deserts, swamps or mountainous areas, and the natural environment is relatively harsh. When laying steel pipelines, it is seriously affected by the natural environment, and due to ground subsidence, landslides and other reasons, the pipelines are extremely prone to damage. Phenomenon. Due to its low density, high strength, and excellent mechanical properties, such as good processing performance, good chemical resistance...

AI Technical Summary

Problems solved by technology

The composite pipe produced by this equipment needs to be wound in multiple layers to ensure that the prepared pipe reaches the required strength. However, since the thickness of the continuous fiber is very small, the bonding layer formed by directly winding the inner pipe surface is very small. At the same time, each The successive winding of layers of fibers often results in limited or no bonding in the area where the fibers are in contact, resulting in weak bonding between layers, which has limited effect on improving the quality of composite pipes, especially the strength.
