Prefabricated overhead steam heat preservation pipeline and production technology

Abstract

The invention discloses a prefabricated overhead steam heat preservation pipeline and a production technology and belongs to the technical field of steam heat preservation pipeline equipment and production methods. The prefabricated overhead steam heat preservation pipeline and the production technology are used for improving the heat preservation effect and corrosion resistance of an overhead steam heat preservation pipe and are convenient to construct. The adopted technical scheme is as follows: the internal insulating layer of the prefabricated overhead steam heat preservation pipeline is a high-temperature-resistant inorganic insulating layer, the external insulating layer of the prefabricated overhead steam heat preservation pipeline is an organic insulating layer, the external protecting pipe of the prefabricated overhead steam heat preservation pipeline is a galvanized air pipe, the internal insulating layer wraps the periphery of a working steel pipe, the external insulating layer wraps the periphery of the internal insulating layer, and the external protecting pipe sleeves the external insulating layer. The prefabricated overhead steam heat preservation pipeline, disclosed by the invention, breaks through the traditional heat preservation structure, adopts the dual heat preservation structure of the combination of the high-temperature-resistant inorganic insulating layer and the organic insulating layer, is innovation for steam heat preservation pipelines, effectively solves the problems that the traditional steam heat preservation pipeline is inconvenient to construct, poor in heat preservation effect, easy to corrode and the like, is simple and practical in production technology, can effectively reduce the production cost, ensures the product quality, and has great popularization and application value.

Description

technical field [0001] The invention relates to a prefabricated overhead steam heat preservation pipeline and a production process thereof, and belongs to the technical field of steam heat preservation pipeline equipment and production methods. Background technique [0002] Steam insulation pipelines are necessary production facilities for factories and mines. They are used for the transportation of high-temperature steam. Steam insulation pipelines are generally divided into two types: direct buried insulation pipelines and overhead insulation pipelines. They each have their own advantages and disadvantages and are suitable for different situations. Prefabricated directly buried steam insulation pipelines have the advantages of lower engineering cost, low heat loss, energy saving, anti-corrosion, less land occupation, and environmental protection, but the construction and maintenance are complicated. The construction and maintenance of the overhead steam insulation pipeline...
