Heat supply pipeline

Abstract

The invention provides a heat supply pipeline. The heat supply pipeline comprises seamless steel pipes, heat preservation and insulation sleeves, connecting assemblies and hanging assemblies. The multiple seamless steel pipes are connected and fixed through the connecting assemblies, the hanging assemblies are installed on the outer walls of the seamless steel pipes, the hanging assemblies are fixed to the wall through bolts, and the outer walls of the seamless steel pipes are sleeved with the heat preservation and insulation sleeves. According to the heat supply pipeline, the problems that in the installation and use process of an existing heat supply pipeline with hot water as a circulation medium in an overground laying mode, heat expansion and cold contraction of a hot water pipeline are caused by temperature changes, the position cannot be adjusted through the generated tension, the pipeline is likely to crack, and in the use process of the hot water pipeline, hot water in the pipeline has incrustation, and after long-time use, the incrustation remains in the pipeline to influence the circulation effect of the pipeline are solved.

Description

technical field [0001] The invention relates to the technical field of pipelines, in particular to a heating pipeline. Background technique [0002] Heating pipelines, also known as heat pipe networks, are a type of pressure pipelines that transport the heat energy produced by boilers to indoor heating equipment through steam and hot water to meet the needs of production and life. The most common heating pipes are seamless steel pipes and welded steel pipes; there are two types of media circulating inside the heating pipes: hot water and steam; they are mainly divided into two methods: low laying and ground laying. [0003] For the heating pipes whose circulation medium is hot water, the method of laying on the ground mainly has the following problems in the process of installation and use: the thermal expansion and contraction of the hot water pipes due to temperature changes. The temperature of the pipeline during installation is normal temperature. During the initial ope...

AI Technical Summary

Problems solved by technology

The temperature of the pipeline during installation is normal temperature. During the initial operation, due to the sudden rise in temperature, the pipeline will elongate sharply. When it is stopped, the pipeline will gradually shrink back as the temperature drops; Medium; due to the current way of laying fixed pipes on the ground, the position of the pipe itself cannot be adjusted; thus, the pipe is prone to rupture due to changes in the internal tension of the pipe; Scale will remain in the pipe after the final effect on the circulation effect of the pipe
