Device for prefabricating composite heat-insulation pipe

Abstract

The invention provides a device for prefabricating a composite heat-insulation pipe. The device for prefabricating the composite heat-insulation pipe comprises a shared structure body, a plurality of inner wall corrosion-prevention and heat-insulation machining mechanisms, a plurality of outer wall corrosion-prevention and heat-insulation machining mechanisms and a controller. The inner wall corrosion-prevention and heat-insulation machining mechanisms are located in front of or behind the shared structure body, and the outer wall corrosion-prevention and heat-insulation machining mechanisms are located on the two sides of the shared structure body; and the controller is connected with the shared structure body, the outer wall corrosion-prevention and heat-insulation machining mechanisms and the inner wall corrosion-prevention and heat-insulation machining mechanisms through circuits correspondingly. The device for prefabricating the composite heat-insulation pipe is high in mechanization level and high in efficiency, and a finally-formed product can insulate heat and reduce resistance and good in corrosion resistance.

Description

technical field [0001] The invention belongs to the field of pipelines, and in particular relates to a device for prefabricating composite thermal insulation pipes. Background technique [0002] With the needs of modern production or life, long-distance pipelines are widely used. In some special industries, such as oil transportation, gas transmission, heating pipelines and other fields, it is necessary to spray a certain thickness and composition of paint on the inner wall of the pipeline, especially for long-distance pipelines. The inner wall coating of the pipeline can play the role of drag reduction and energy saving. In addition, the traditional prefabrication method of thermal insulation pipes wastes a lot of raw materials. When the length of the pipeline increases sharply, switching to the spraying and winding method with a small amount of material can greatly save energy and reduce emissions. However, the current conventional pipeline inner wall spraying and pipelin...

Problems solved by technology

In addition, the traditional prefabrication method of thermal insulation pipes wastes a lot of raw materials. When the length of the pipeline increases sharply, the spraying and winding method with a small amount of material can be used to save energy and reduce emissions to a large extent.

However, the conventional spraying of the inner wall of the pipeline and the spraying and winding process of the outer wall of the pipeline are fragmented and complicated, the turnover is difficult, the space is large, the processing time is long, and the process and method are far from meeting the needs of today's enterprises.
