Description

Technical Field

[0001] The utility model relates to the technical field of pipeline cooling equipment, in particular to cooling equipment for pipeline production. Background Art

[0002] Pipe products that are hot-dip-coated with PE or coated with epoxy resin inside and outside have excellent corrosion resistance. In the process of pipeline production, the cooling link of pipe fittings is very important. Quick and effective cooling of pipe fittings to make them shrink evenly is of great significance to improving the qualified rate of products, saving personnel and improving labor productivity.

[0003] The existing cooling equipment for pipeline production (authorization announcement number CN219776105U) has the following defects: the above-mentioned device cools down the inside of the pipeline through the nozzle in the column, and then uses the air pump to make the air pipe on the column absorb water vapor in the pipeline to reduce the deformation of the pipeline caused by the air pressure. However, the air pipe evacuates air and sprays water to cool down at the same time. When the air pipe extracts air, liquid is easily sucked into the air pipe, which can easily cause equipment failure and further affect the cooling effect of the pipeline. For this reason, we propose the utility model. Utility Model Content
