Coiling type one-step corrosion preventing and heat preserving operating line of steel pipeline

Abstract

The invention relates to a coiling type one-step corrosion preventing and heat preserving operating line of a steel pipeline. The coiling type one-step corrosion preventing and heat preserving operating line of the steel pipeline comprises a pipe feeding platform, a conveyor, an intermediate frequency preheating system, an external impeller blasting machine, a dust removal system, an intermediate frequency heating system, an epoxy powder coating system, a water spraying cooling system, a steel pipe temperature conditioning device, a spraying foaming device, a copolymer tape coiling device and an PE belt coiling device; the conveyor forwards pushes the steel pipeline to be processed on the pipe feeding platform; the intermediate frequency preheating system is positioned between the conveyor and the external impeller blasting machine and used for heating and dehumidifying the steel pipeline to be processed. The processing technical devices in the operating line overcomes part of shortages in an one-step operating line of a foam jacket heat preserving pipe in the prior art as well as the shortage of two-step manufacturing of a corrosion preventing and heat preserving pipe in the prior art, and has the advantages of being wide in applicable scope, and high in efficiency.

Description

technical field [0001] The invention belongs to the technical field of anti-corrosion and heat-preservation foam coating on the outer wall of steel pipes, and in particular relates to a steel pipe anti-corrosion and heat-preservation treatment process method and equipment. technical background [0002] Pipeline transportation is a safe and economical way of transporting fluid media such as oil, water, and gas in large quantities. It has a history of more than 100 years in the world. However, the corrosion of pipelines is a key factor affecting the reliability and service life of pipeline systems. my country's pipeline anticorrosion technology has developed rapidly, but there is still a big gap compared with developed countries. With the adjustment of my country's energy policy, the construction of long-distance pipelines has reached a climax in my country, which puts forward new requirements for pipeline anticorrosion and heat preservation. [0003] Three-layer PE (three-la...

Problems solved by technology

[0004] In view of the above problems, the present invention provides a steel pipe winding type "one-step" anti-corrosion and heat preservation operation line. The steel pipe after the anti-corrosion and heat preservation treatment overcomes the heat preservation The disadvantages of poor anti-corrosion function of the pipe and the inability to keep heat in the anti-corrosion pipe operation line greatly prolong the service life of the products treated with this process and reduce the use cost
