       DC150 Inner-Coated Powder for Industrial Pipe

Properties and Applications  

DC150 is a kind of Epoxy-Phenolic powder coating materials application for chemical pipe especially for the anticorrosion 

and wear-resisting oil pipe and drill pipe. Connected with PC8007 resin the DC150 coating layer will be more useful in the

high concentration COand H2S medium, Also great resistance in chemical pipe. This coating layer can increase 3~4times

life of the drill pipe than untreated. As the smooth surface of the pipe can reduce the resistance on freighting the oil, Chemical

materials, and other corrosion liquid. The needed transfer power can be less than normal about 15~30%. As the main

component are epoxy the suitable max temperature can reach 150 which main be suitable for most high temperature

request field.
