Method for manufacturing fiber resin reinforced composite pipe through centrifugal casting

Abstract

The invention relates to a method for manufacturing a fiber resin reinforced composite pipe through centrifugal casting, which overcomes the defects that metal pipelines have poor corrosion resistance and abrasion resistance and resin pipelines cannot meet long-distance construction in the prior art. The invention adopts the following technical scheme that: a composite casting ground mass comprises fiber and / or fiber whisker and resin; the manufacturing method comprises the following steps of: performing roughening preprocessing on the inner surface of the selected metal pipe according to design requirements; cleaning the inner surface of the metal pipe after the standardized preprocessing; positioning the processed metal pipe on a centrifugal casting machine for preheating; performing centrifugal casting on the configured fiber and resin ground mass to form a composite inner wall of the metal pipe; and heating the cast metal pipe, and curing the inner wall of the fiber resin metal pipe. The method is simple to implement, improves the corrosion resistance, antistatic behavior, abrasion resistance and flame retardance of the fiber resin reinforced composite pipe, and is easy to carry out long-distance construction.

Description

Background technique [0001] The invention involves a improvement of the production method of flames, liquids, or fluidized solid transmission tubes, and especially involves a method of making fibrous resins to enhance composite tube with centrifugal casting. Background technique [0002] Oil fields, chemicals, ships, coal mines, mines, municipalities and other occasions require large pipeline transportation gas, liquid, and even fluidization solids.Many flammable and explosive occasions require large pipelines to transport gas, liquid, and even fluidized solids.Many gases, liquid or liquid curing of the pipelines are flammable and explosive items, such as various transportation pipelines under the mine, such as underground air with high gas content, blast furnace gas, and flour ash.These industrial and mining conditions have high requirements for transmission pipelines, such as combustion, anti -static, abrasion resistance, corrosion resistance, and anti -seepage.
