Intensive thermal insulation device and method for small-diameter pipelines

Abstract

The invention discloses a small-caliber-pipeline intensive type heat preservation device and method. The small-caliber-pipeline intensive type heat preservation device comprises a heat preservation layer and an outer protective layer frame type support. The heat preservation layer comprises first aluminum silicate fiber blankets and a composite heat preservation structure. Each first aluminum silicate fiber blanket is wrapped around a single pipeline needing heat preservation. Each first aluminum silicate fiber blanket is externally bundled with a galvanized iron wire. The composite heat preservation structure is wrapped around a row of pipelines wrapped inside the first aluminum silicate fiber blankets. The outer side of the composite heat preservation structure is bundled with iron gauze. The outer layer of the iron gauze is provided with the outer protective layer frame type support. Corrugated plates and corner wrapping plates are arranged on the outer protective layer frame type support and are fixed with self-tapping screws. The corrugated plates are arranged on the outer surface of the outer protective layer frame type support. The corner wrapping plates are arranged at the corners of the outer protective layer frame type support. By the adoption of the small-caliber-pipeline intensive type heat preservation device and method, the construction efficiency and the installation quality level can be improved, and the construction cost can be reduced.

Description

Technical field: [0001] The invention relates to an intensive thermal insulation device and method, in particular to an intensive thermal insulation device and method for small-caliber pipelines. Background technique: [0002] In the installation of thermal power plants, the small-diameter pipes of the steam-water system such as boiler drainage pipes, steam turbine drainage pipes, and steam fire-fighting pipes are important installation links in the construction. Selecting the appropriate small-diameter pipe layout and insulation method can improve the quality of heat preservation. It directly affects the appearance and craft quality of the power plant and the operation convenience of the operating personnel. In the design of thermal power plants, generally, the design unit does not design detailed layout drawings for steam-water pipelines below φ76 due to many on-site constraints. Lack of attention and overall planning during construction resulted in disordered layout, poor...

[0002] In the installation of thermal power plants, the small-diameter pipes of the steam-water system such as boiler drainage pipes, steam turbine drainage pipes, and steam fire-fighting pipes are important installation links in the construction. Selecting the appropriate small-diameter pipe layout and insulation method can improve the quality of heat preservation. It directly affects the appearance and craft quality of the power plant and the operation convenience of the operating personnel. In the design of thermal power plants, generally, the design unit does not design detailed layout drawings for steam-water pipelines below φ76 due to many on-site constraints. Lack of attention and overall planning in the construction, there are phenomena of messy layout, poor appearance technology, and low protection ability, which seriously affect the overall appearance technology quality of the unit, the convenience of operation and maintenance, and the overall project quality evaluation
