3LPP Coated Steel Pipe Suppliers in China - High-Performance Polypropylene Coating Factory
Detailed Description of 3LPP Coated Steel Pipe
The 3LPP coating system offers a pipeline protection solution based on 3LPE technology tailored for elevated temperature situations and claims the same construction scheme as 3LPE but with the outer layer being polypropylene (PP). PP is ideally suited for high temperature pipeline service because of its excellent mechanical properties and temperature resistance. With that, it is the camera in hot oil or steam pipelines and pipelines crossing high temperature areas (i.e. deserts or geothermal).
Provides corrosion prevention as well as superb adhesion to steel.
The adhesive used to bond the FBE primer to the PP topcoat.
Corrosion resistant, high temperature resistance, high hardness, high abrasion resistance. Also provides protection against mechanical damage.
