3LPP Pipe Coating i a three layer polypropylene coating technique that uses polypropylene as the coating material.There are three layers in this coating.The outer layer is the polypropylene in the 3lpp pipe coating and there is a middle layer made up of adhesives to bond the epoxy layer inside that is fusion bonded. This special structure protects the material from a number of conditions and materials.
The 3lpp pipeline coating is excellent in preventing the steel pipes from being in contact with corrosive chemicals and agents.Also the coating prevents the material to come into contact with any hard surfaced directly and prevents physical damage as wel.
The 3lpp coating pipe can come in different specifications such as DIN30678,CSAZ245.21-02,NF A49-711,ISO 9001:2008.The coating is also resistant to cathodic disbondment, meaning, thee coating is not affected by electric charge which can damage most other types of coatings. The 3lpp pipe can last longer and has higher performance compared to non - coated or other types of coatings. The application of this special coating is mostly in the oil fields which operate under high temperatures.The Three Layer Polypropylene Coated Pipe can be used in abrasion prone applications such as driling operations and in rocky surface applications.
A polypropylene(PP) coating in compliance with this standard shall be designated
