    Parameter of usage

    1. Technological process for powder paint

    External storage----- high temperature quick burning----- shot (or sand) blasting treatment----- pre-heating pipelines

    ----- powder coating----- cooling----- inspecting----- additional coating----- finished products

    2. Internal spraying and coating procedure of pipeline

    (1) Getting rid of oil, rust, loose sediment, water, etc.

    (2) After treatment of blast cleaning or slot blasting, the surface could reach Grade Sa 2.5 and the profile depth is 40-100μm. The surface dedusting should reach near-white grade.

    The new or old sand should be added uniformly in order to keep the proportion stable.

    (3) Clean the surface of pipelines.

    (4) Pre-heat work pieces, the temperature of which should be controlled within 180-240℃ but does not exceed 260℃.

    (5) Coat the internal anti-corrosive powder paint on surface of work pieces till the required thickness is reached.

    (6) Deal with curing according to requirements.

    (7) Cool coating.

    (8) Inspect surface when the temperature of work piece is lowered to 95℃.

    (9) Additional coating of uncoated areas.
