Abstract

The invention discloses an integrated customizable composite thermal insulation pipe which comprises an inner core pipe, a high-temperature-resistant thermal insulation cotton layer, a foaming thermal insulation material layer and an outer casing pipe, wherein the high-temperature-resistant thermal insulation cotton layer is positioned on the inner core pipe; and the foaming thermal insulation material layer is positioned between the high-temperature-resistant thermal insulation cotton layer and the outer casing pipe. A production method of the integrated customizable composite thermal insulation pipe comprises the following steps: (S1) laying high-temperature-resistant thermal insulation cotton on a floating bed; (S2) placing the inner core pipe on a rotating support of the floating bed, and spraying a high-temperature-resistant adhesive; (S3) opening an air supply valve so as to enable the high-temperature-resistant thermal insulation cotton to float upwards and to be bonded to the inner core pipe; (S4) closing the air supply valve when the thickness of the high-temperature-resistant thermal insulation cotton on the inner core pipe reaches 4-7 cm; and (S5) sleeving the inner core pipe bonded with the high-temperature-resistant thermal insulation cotton with the outer casing pipe rolled through a spiral air duct machine, blocking the two ends of the outer casing pipe, and injecting a foaming thermal insulation material into the outer casing pipe. The thermal insulation pipe disclosed by the invention has the advantages of being convenient to use and good in thermal insulation effect. The production method disclosed by the invention has the advantages of convenience, quickness, pollution reduction and cost reduction.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation pipes, and in particular relates to an integrated and customizable composite thermal insulation pipe and a production method thereof. Background technique [0002] Insulation pipe is the abbreviation of heat insulation pipe, which is used for the transportation of liquid, gas and other media, and is used for heat insulation of petroleum, chemical, aerospace, hot spring, military, central heating, central air conditioning, municipal and other pipelines. [0003] With the development of society, the demand for thermal insulation pipes in industrial production continues to grow. Most factories first install the pipelines that need to be insulated, and then wrap or apply insulation materials, which makes the installation of insulated pipelines extremely inconvenient. [0004] As the insulation materials used in the factory gradually age, they need to be replaced or directly removed. These...
