Problems solved by technology

[0003] The purpose of the present invention is to provide an impact-resistant and non-flammable fire-fighting water pipe and its manufacturing method, so as to solve the problem that the existing fire-fighting water pipe proposed in the above-mentioned background technology is not resistant to high pressure, corrosion, flammable, and easy to burn at high temperatures. Causes damage to the water pipe and cannot meet the needs of use. The outer layer of the existing fire-fighting water pipe production process is directly bonded to the blank, the inner and outer layers are not related, and the integrity is not good. Moreover, each process of the process is independent. It will cause defective products, more labor, and affect the stability of quality.

Abstract

The invention discloses an impact-resistant non-flammable fire-fighting water pipe and a manufacturing method thereof in the technical field of fire-fighting water pipes. The impact-resistant non-flammable fire-fighting water pipe comprises an inner pipe body; a reinforcing layer is arranged on the outer wall of the inner pipe body; a protective layer is arranged on the outer wall of the reinforcing layer; and a flame-retardant fiber layer is arranged on the outer wall of the protective layer. An EVOH material is mainly adopted, air tightness is high, impact of high-pressure water can be effectively prevented, and the structure stability is improved; the toughness of the fire-fighting water pipe is improved through the reinforcing layer formed by weaving of glass fibers and metal wires, and the impact resistance of the fire-fighting water pipe is further improved; the protective layer has the functions of fire prevention, flame retardance and heat preservation; flame-retardant fibers are arranged on the outermost layer of the fire-fighting water pipe, and the flame-retardant effect is further achieved; and the manufacturing method of the fire-fighting water pipe is high in automation degree, high in production efficiency, large in capacity and low in defective rate, and the phenomenon of uneven rubber pipe local tensile wall thickness caused by pipe penetrating is overcome.

Description

technical field [0001] The invention relates to the technical field of fire-fighting water pipes, in particular to an impact-resistant and non-flammable fire-fighting water pipe and a manufacturing method thereof. Background technique [0002] For fire safety, the country is committed to research and development of fire-fighting equipment suitable for various occasions. Because fire-fighting water pipes have to withstand different environmental tests, fire-fighting water pipes are often treated differently from ordinary water pipes in terms of structure and performance due to their special use environments. . At present, the fire-fighting water pipes used have more or less certain defects, such as not being resistant to high pressure, not being corrosion-resistant, flammable, and easily causing damage to the water pipes under high temperature conditions, which cannot meet the needs of use. The existing fire-fighting water pipes The outer layer of the manufacturing process i...
