Anti-corrosion steel pipe manufacturer < br b Steel-sheathed steel direct-buried steam insulation pipe Steel-sheathed steel direct-buried steam insulation pipe is composed of a steel pipe with an anti-corrosion jacket for transporting the medium, and ultra-fine glass wool filled between the steel pipe and the jacket. The insulation structure of steel-sleeved steel directly buried steam insulation pipes is divided into internal sliding type and external sliding type according to different sliding methods. Application Steel-sleeved steel direct-buried steam insulation pipes are widely used in liquid gas transportation pipeline networks, chemical pipeline insulation projects, petrochemical centralized supply Reheat network central air-conditioning ventilation duct municipal engineering, etc. Use steel sheathed steel directly buried steam insulation pipes for thermal insulation sliding lubrication and waterproofing of exposed pipe ends. Insulated pipes not only have advanced technical and practical performance that are difficult to match with traditional trenches and overhead pipes, but also have significant social and economic benefits, and are also a powerful measure for heating and energy saving.

< br brThe three-layer anti-corrosion structure of the pipeline has the first layer of epoxy powder B>, the second layer of adhesive~, and the third layer of polyethylene~. The three materials are integrated and firmly combined with the steel pipe to form an excellent anti-corrosion layer. This is a relatively good anti-corrosion method between the pipe diameter range ~ and the wall thickness range. It can generally increase the service life of the year. It not only extends the replacement cycle of underground pipeline equipment, but also greatly saves costs and provides a strong force for national construction. The role! Anti-corrosion is the most commonly used anti-corrosion method. In addition, there are also: Anti-corrosion method! In addition, the company has powerful professional production equipment and can independently undertake anti-corrosion and insulation projects. New and old customers are welcome to call the factory for consultation! The anti-corrosion layer is crucial to the life of buried pipelines. Some pipelines of the same material will not corrode after being buried underground for decades, while others will leak within a few years. It is because they use different external anti-corrosion layers of anti-corrosion steel pipes.
