Antirust characteristics

As the analysis has shown, impregnation of Cl in polymer coating compositions significantly improves their antirust characteristics leaving sufficiently high adhesive and other service characteristics of the coatings. 

PI incorporated in inhibited plastics and Cl significantly influence the physical-mechanical and physical-chemical characteristics of materials. The three-component composition-property charts presented in Fig. 4.24 help to estimate the effect of Cl and PI on the mechanical and antirust properties of composites. 

Transport of gasoline and other refined products in steel pipelines may result in corrosion products that can create a product contamination problem. Internal corrosion of the pipeline can also have an adverse effect on pipeline capacity. Corrosion results from condensation of a water film on the pipe wall plus dissolved air or SRB in the product. Corrosion control is commonly achieved by adding a corrosion inhibitor. Evaluation of inhibitor performance can be done using NACE Test Method for Antirust Properties of Cargoes in Petroleum Product Pipeline (TM0172). This test method is a modification of ASTM D 665, Test Method for Rust-Preventing Characteristics of Inhibited Mineral Oil in the Presence of Water.
