Pipeline anti-corrosion is very important for a project. It plays a decisive role in the quality of the whole project. The service life of anti-corrosive pipelines can reach 50 years,so strictly design and reasonable application are required.
Fusion bonded epoxy(FBE) coating steel pipe
Inner wall anti-corrosive coating:In order to prevent corrosion in the pipe, reduce friction resistance, improve the flow rate and coat the film on the inner wall of the pipe. The common anti-corrosive coatings are amine cured epoxy resin and polyamide epoxy resin. The thickness of coatings is 0.038-0.2mm. In order to ensure that the coating is firmly bonded to the pipe wall, it is necessary to carry out surface treatment on the inner wall of the pipe. Since the 1970s, it has tended to choose the same material for inner and outer wall coatings, so that both inner and outer wall coatings can be carried out simultaneously.
3PE anti corrosion coating steel pipes
Anti-corrosion and heat preservation coating: In order to reduce heat dissipation from pipeline to soil, a composite layer of heat preservation and anti-corrosion is added to the outside of pipeline on medium and small diameter pipelines for heat transportation of crude oil or fuel oil. The commonly used heat preservation material is rigid polyurethane foam plastics, the applicable temperature is – 185 – 95 °C. In order to improve its strength, a layer of high density polyethylene (HDPE) is added to the insulation layer to form a composite structure to prevent groundwater from seeping into the insulation layer.
