Double-layer sintered epoxy powder anti-corrosion technology concept
Sintered epoxy powder steel pipes are usually divided into two types, namely single layer and double layer, for single-layer power wiring with heat The plastic-impregnated steel pipe layer has the problem of weak mechanical impact resistance and poor waterproofing. The American Anti-Corrosion Company has studied the material structure and construction technology of a large number of anti-corrosion layers, proposed the technical idea of modified epoxy powder materials, and established a double-layer The concept of sintered epoxy powder anti-corrosion system refers to using a standard single layer of sintered epoxy powder as the base coating and modified sintered epoxy powder as the outer protective layer. In this way, the mechanical properties of the anti-corrosion layer are significantly improved, and the high-temperature resistance to permeability and impact resistance of the anti-corrosion layer are greatly enhanced. In addition, the advantages of the single-layer sintered epoxy powder anti-corrosion layer and cathodic protection are retained. Compatible performance avoids the occurrence of cathodic protection shielding. The thickness of the overall anti-corrosion layer of the double-layer sintered epoxy powder anti-corrosion system is between
The coating process used in the hot-dip plastic steel pipe system for double-layer power wiring is basically the same as the standard fusion-bonded epoxy powder spraying process. The only changes are the layout of the powder spraying chamber and the spray gun. There is no need to add complicated equipment. There are two types of powder spraying chamber spray gun layouts: double powder spraying chamber and integral powder spraying chamber, both of which are used for coating double-layer sintered epoxy powder anti-corrosion systems. Laboratory testing and field application tests have proven that the comprehensive performance of the double-layer sintered epoxy powder anti-corrosion system used in long-distance pipelines is better than that of a single-layer epoxy powder anti-corrosion layer. It has a high cost performance and is also effective in use. It has the characteristics of longer life, lower maintenance cost, multiple anti-corrosion layer types, etc. Its type can be selected according to different needs. It can be used in different pipeline constructions, especially when construction is required in crossing and mountainous areas, and it can resist chemical corrosion. corrosion of the soil, has a wide adaptability to temperature and applicable pipe diameters, and is applicable to various special-shaped parts. During on-site construction, there are relatively mature processes such as patching construction and repairing, which makes quality control easier and has better scratch resistance. It has superior impact resistance and is even comparable to three-layer anti-corrosion structures. This system has strong bonding properties and good water permeability resistance, and has been widely used in long-distance pipeline projects.
