1) According to the method of use, it can be divided into: pipes in the pipeline, pipes outside the pipeline, and universal powder inside and outside the pipeline. Powers are divided into: single -layer powder, double -layer powder, and three -layer structure of anticorrosive powder.
2) It can be divided into: oil and natural gas pipeline powder, drinking water pipeline powder, powder pipe powder, coal mine anti -static ventilation pipeline powder, chemical pipeline powder, petroleum drilling rod powder, pipeline powder, ship pipeline for pipelines, pipe parts powder, pipelines, and ship pipelines Powder, high saline heavy anticorrosive pipelines, etc. are used.
3) According to the condition of curing, it can be divided into: fast solidification and ordinary solidification. The curing conditions of fast curing powder are generally 230 ° C/0.5 ~ 2min, which are mainly used for spraying or three layers of anti -corrosion structures outside the pipeline. Due to the short curing time and high production efficiency, it is suitable for assembly line operations. /5min or more, due to the long curing time, the coating flow is flat, and it is suitable for spraying in the pipeline.
