3PE anticorrosive straight seam pipe for winding gas pipeline.
With the acceleration of urbanization, gas pipelines are playing an increasingly important role in urban infrastructure. In order to ensure the safe operation of gas pipelines, anti-corrosion technology has become the key. Among them, 3PE anti-corrosion technology, as an efficient and environmentally friendly anti-corrosion method, has been widely used in the field of gas pipelines. This article will focus on the characteristics, advantages, production process and application of 3PE anticorrosive straight seam pipe for spiral wound gas pipeline.
1. Characteristics and advantages of 3PE anticorrosive straight seam pipe for winding gas pipeline.
3PE anti-corrosion technology is an anti-corrosion layer composed of polyethylene (PE) material, fused epoxy powder (FBE) and adhesive, which has excellent anti-corrosion performance, insulation performance and anti-aging performance. The 3PE anti-corrosion longitudinal seam pipe for winding gas pipeline is a steel pipe produced by longitudinal seam welding process, and then coated with a 3PE anti-corrosion layer on its surface. This type of pipeline has the following characteristics and advantages:
1.Excellent anti-corrosion performance: 3PE anti-corrosion layer can effectively resist the corrosion of acids, alkalis, salts and other chemicals, and significantly improve the service life of gas pipelines.
2.Good insulation performance: 3PE anti-corrosion layer has excellent electrical insulation performance, which can effectively prevent the occurrence of electrochemical corrosion.
3.Strong anti-aging performance: The adhesive in the 3PE anti-corrosion layer can be firmly bonded with the surface of the steel pipe, and contains anti-aging and anti-oxidation additives, so that the pipeline has excellent weather resistance and durability.
4.Good welding performance: The winding gas pipeline adopts the longitudinal seam welding process, which has excellent welding performance and can ensure the air tightness and water tightness of the pipeline.
5.Easy installation: The pipes are lightweight, easy to transport and install, which can reduce the difficulty and cost of construction.
2. Production process of 3PE anticorrosive straight seam pipe for winding gas pipeline.
The production process of 3PE anticorrosive straight seam pipe for spiral wound gas pipeline mainly includes the following steps:
1.Steel pipe production and pretreatment: According to relevant standards and customer requirements, the longitudinal seam welding process is used to produce steel pipes, and pretreatment work such as rust removal and oil removal is carried out to ensure that the cleanliness and roughness of the steel pipe surface meet the requirements.
2.Coating fused epoxy powder (FBE): The pretreated steel pipe is passed through the fused epoxy powder coating line to evenly coat the surface of the steel pipe with a layer of FBE anti-corrosion layer.
