The double-layer fused epoxy powder outer anticorrosion layer is composed of an inner layer of fused epoxy powder and an outer layer of modified fused epoxy powder. Two different epoxy powders, inside and outside, are sprayed into a film at one time during the spraying process.

Fused epoxy powder outer coating (FBE/2FBE) is a new type of anti-corrosion coating developed in the past 30 years. FBE coating has two types: single layer and double layer. The so-called FBE coating generally refers to a single-layer fusion bonded epoxy coating.

The three-layer structure polyethylene anticorrosion layer combines the excellent properties of epoxy coating and extruded polyethylene anticorrosion layer, combining the interface characteristics and chemical resistance of epoxy coating with the mechanical protection characteristics of extruded polyethylene anticorrosion layer Combining other advantages, thus significantly improving their performance. Therefore, it is very superior as the outer protective layer of buried pipelines.

The surface of the steel pipe is electrostatically sprayed with epoxy powder, and the adhesive is wound laterally, and the polyethylene anticorrosive layer is wound laterally. Combining the excellent performance of the three, the overall quality of the anticorrosive pipeline is significantly improved. It is resistant to chemical corrosion, cathodic disbondment and mechanical damage.

The anticorrosive system of polyethylene anticorrosive adhesive tape is composed of anticorrosive tape, protective tape, mending tape and primer. Adhesive tape is a tape-shaped anticorrosive material made of polyethylene base film, thermally laminated with an adhesive layer mainly composed of butyl rubber, and co-extruded.

The production of FRP on the surface of carbon steel, concrete or other substrates to prevent the substrate from being damaged or deteriorated under the action of the medium or the environment is called "FRP anticorrosion". Commonly used FRP anticorrosion include: FRP lining, glass flake lining, resin cement brick lining, epoxy self-leveling, epoxy powder spraying, substrate surface coated with FRP, etc.

The future development of polyurea anticorrosive steel pipes polyurea coatings represents the latest international anticorrosion technology trend. At present, major international pipeline companies have used polyurea anticorrosive coatings.

2PE/3PE anti-corrosion structure: electrostatic spraying epoxy powder on the surface of the steel pipe and laterally wound adhesive and laterally wound polyethylene anticorrosive layer, combining the excellent performance of the three, thus significantly improving the overall quality of the anticorrosive pipeline. It is resistant to chemical corrosion, cathodic disbondment and mechanical damage.

It is resistant to chemical corrosion, cathodic disbondment and mechanical damage.

Plastic-coated composite steel pipe is a new type of pipeline material newly developed in China. It adopts a composite structure of reinforced welded steel pipe or seamless pressure-bearing steel pipe with a plastic protective layer inside and outside, which overcomes the easy rust and corrosion of the steel pipe itself.

The future development of polyurea anticorrosive elbow polyurea coating represents the latest international anticorrosion technology trend. At present, major international pipeline companies have used polyurea anticorrosive coatings. For example, the oil pipelines in Alaska, the Gulf oil pipeline in Indonesia, the Siberian oil pipeline in Russia, and the water pipeline in Kuwait all use polyurea as anticorrosive coatings.

The inner and outer coated epoxy resin elbows are thermosetting plastics because of the heavy-duty anti-corrosion modified epoxy resin. The coating has good temperature resistance and can be used for a long time at -30℃~200℃ without burning. At the same time, it has chemical corrosion resistance, extinguishing agent corrosion resistance, high temperature resistance and wood pile fire resistance, as well as anti-corrosion or flame resistance under water and no water conditions.

Fused epoxy powder outer coating (FBE/2FBE) is a new type of anti-corrosion coating developed in the past 30 years. FBE coating has two types: single layer and double layer. The so-called FBE coating generally refers to a single-layer fusion bonded epoxy coating. The single-layer FBE coating uses special fusion bonded epoxy powder coating as the film-forming material.

Polypropylene cold-wrapped tape is a new type of non-polluting, non-hazardous, environmentally friendly anti-corrosion product. It represents the highest level of international and domestic cold-wrapped anti-corrosion tapes and has the reputation of "Crown of Anti-corrosion".

The anticorrosive system of polyethylene anticorrosive adhesive tape is composed of anticorrosive tape, protective tape, mending tape and primer. Adhesive tape is a tape-shaped anticorrosive material made of polyethylene base film, thermally laminated with an adhesive layer mainly composed of butyl rubber, and co-extruded.

The elbow anticorrosive heat shrinkable tape is a new type of anticorrosive material for steel pipe welds with good performance and easy operation. It is composed of a base material and a double layer of hot melt adhesive.
