Spiral steel pipe 3PE outer /inner coating
3PE Steel Pipe Coating Line is used to coating industry and city construction work in natural gas, coal liquid and oil transportation hose system.
3PE Steel Pipe Coating Line is combined with North American FBE and European PE barrier protection layer to form multi-layers coating system. It is honored as “Never ever corrosive system” for its’ high performance. It is widely used in oil, air and water transportation engineering system, also extends through to ocean pipeline in recent years. It is applied to Single-layer FBE, Double-layers FBE, Double-layers PE, Double-layers PP and 3PE anticorrosive Steel pipe coating.
Complete coating line for steel pipe, 3PE anti-corrosion layers, suitable for diameter scope Φ159-Φ1220.
3PE Anti-corrosion
Anti-corrosion structure of 3PE layer for the pipeline, the first layer is epoxy powder (FBE>100μm), the second layer is viscose adhesive (AD) 170-250μm, the third layer is polyethylene(PE) 2.5-3.7μm, the fusion of three kinds of materials which can be combined with steel pipeline and then in the form of the anti-corrosion layer, its performance is very good.. The scope of the pipe diameter is φ159-φ1220.
2PE Anti-corrosion
Anti-corrosion structure of 2PE layer for the pipeline, the first layer is viscose adhesive (AD), the second layer is polyethylene(PE), two kinds of materials melt together, the thick of every layer is the same as the 3PE Anti-corrosion.
