anticorrosive coating (FBE) has strong adhesion to the surface of steel pipe, good corrosion resistance to chemical media, good temperature resistance, corrosion resistance, cathodic stripping resistance, aging resistance, soil stress resistance, and other properties are also outstanding, and the temperature range is wide (common FBE epoxy powder is -30~100℃, Suitable for most soil environments and directional drilling through clay soils.
The three-layer polyethylene (3PE) anticorrosive coating combines the characteristics of epoxy powder FBE and two-layer PE coating to overcome the disadvantages of every single anticorrosive process. FBE plays an important role in anti-corrosion. PE mainly plays the role of protecting FBE (resistance to mechanical damage) and has very good resistance to water penetration. The three-layer polyethylene coating system has excellent mechanical properties to meet the performance of the coating material, and the coating temperature can reach 50℃ (low-density and medium-density polyethylene) or 70℃ (high-density polyethylene).
The three-layer polypropylene anticorrosive coating (3PP) is composed of the bottom layer of epoxy powder, the middle layer binder, and the outer layer of the PP (polypropylene) jacket. The 3PP combines all the superior performance of the 3PE and makes a great improvement in service temperature performance. 3PP coating is mainly used as an anticorrosive pipeline conveying medium with higher temperatures and as an anticorrosive layer for pipelines in desert areas with higher surface temperatures and longer sunshine time. Therefore, buried water, gas, and oil pipelines in areas with higher surface temperatures and longer sunshine time have been more and more widely used.
Epoxy coal asphalt anticorrosive structure: The anticorrosive coating made of epoxy resin + coal tar asphalt + filler is coated with glass cloth as a strengthening coating on the surface of the steel pipe to form an anti-corrosive layer, which is often used for pipeline outer wall anticorrosion.
Organic silicon anticorrosive layer, hard silicon calcium tile insulation layer, galvanized iron wire reinforcement layer, aluminum silicate fiber cloth waterproof layer, steel sleeve, and steel sleeve inside the surface of the titanium aluminum alloy powder of organic silicon coating and the surface of organic silicon coating. The silicone anticorrosive layer is composed of silicone resin, ceramic powder, talc powder, mica powder, aluminum oxide powder, and titanate. With anti-corrosion, heat preservation, waterproof, and external protection performance, the silicone anticorrosive layer can withstand 600℃ high temperatures and can be used for conveying 550℃ high-temperature medium insulation pipeline.
The different conveying medium is mainly divided into two kinds: one is to reduce the friction between the conveying medium of the pipeline and the inner wall of the steel pipe, called "internal drag reduction coating". The drag-reducing inner coating can improve the mobility of the transport medium, reduce the number of pressure stations and reduce pipeline investment. The other is to reduce the corrosion of the conveying medium to the inner wall of the steel pipe, which needs to be coated with a layer of anti-corrosion coating, called "internal anti-corrosion coating". The anti-corrosion inner coating can improve the safety of the pipeline and extend the service life of the pipeline. Different inner coating materials are available for water and other chemical environments.
