Manufacturing method of fireproof conveying pipe

Abstract

The invention discloses a manufacturing method of a fireproof conveying pipe, comprising the steps of: cleaning the outer surfaces of a metal-woven plastic hose, a joint and a sleeve; coating first coats on the outer surfaces of the metal-woven plastic hose, the joint and the sleeve; coating a sealing agent on the surfaces of the first coats after the first coats are volatized; mixing fireproof silicon rubber; thermally pressing the fireproof silicon rubber into the centre place of the outer surface of the metal-woven plastic hose in a vulcanizing machine by using a die; installing the joint and the sleeve onto the metal-woven plastic hose; thermally pressing the fireproof silicon rubber onto the outer surface of the sleeve in the vulcanizing machine by using a die; and performing the two-stage vulcanization in a drying box. According to the manufacturing method of the fireproof conveying pipe, the fireproof material and the metal-woven plastic hose, the fireproof material and the stainless steel, and the fireproof material and the fireproof material can be well bonded, so the fireproof performance is good.

Description

technical field [0001] The invention relates to fireproof equipment, in particular to a method for making a fireproof conveying pipe. Background technique [0002] figure 1 Shown is a steel wire braided fluoroplastic hose in the prior art, which includes a fluoroplastic tube 11 and a steel wire layer 12 wrapped on the outer wall of the fluoroplastic tube 11. This steel wire braided fluoroplastic hose cannot be directly applied to substances under high temperature environments. For example, the steel wire braided fluorine plastic hose cannot be used to transport oil in an aircraft engine, because the temperature of the aircraft engine is high during operation, and even an open flame may be encountered, while the steel wire braided fluorine plastic hose of the prior art only Can work in the environment below 180 ℃. In order to make the steel wire braided fluoroplastic hose work in a high temperature environment, it is necessary to protect the steel wire braided fluoroplastic...
