2LPE coating and 3LPE Coating  for Pipeline

2LPE and 3LPE Coating for Pipe line are important methods for pipe anticorrosion. Today’s pipelines in the oil, gas and water transportation industries worldwide are usually protected by external coatings in conjunction with cathodic protection systems. Pipe coating solution providers are offering various types of products tailored to the needs of their clients. Some of these common pipeline coating products includ 3LPE coating systems that provide excellent anti-corrosion protection to pipes.

 

2LPE Coating for Pipe line refer to coatings that contain one layer of adhesive and another of polyethylene. Currently, the adhesives used in two-layer systems are either mastic-based or copolymers of polyethylene. Mastic-based adhesives, although being relatively inexpensive and providing good cathodic disbondment (C.D.) resistance, have low shear and peel strength values and are restricted to low temperature applications. 

 

3LPE Coating for Pipe line generally consists of an epoxy layer, a copolymer adhesive layer and a layer of polyethylene. This system can be operated at higher temperatures, however, due to the fact that an epoxy layer is required, it is more expensive with a more complex and critical application process.
