Pipe coating and multilayer pipes

Pipe coating and multilayer pipes

Multilayer structures are systems consisting of multiple layers of different materials coupled together. Specifically, multilayer composite pipes can have three or five layers, depending on the type of application. One of the areas where “Compoline CO/LA” adhesives are most used is the water heating sector. In fact, “Compoline CO/LA” guarantees perfect adhesion between the central Aluminum layer (or EVOH) and the outer PE (PERT or PEX) or PP layers (image 2). Another field of ​​application is that of Pipe Coating for the Oil & Gas sector, where the transport of gas, oil or fuel requires steel pipes coated with a protective layer of polyolefin (PE, PP) – (image 1). Even in this situation, the “Compoline CO/LA” adhesives grafted with maleic anhydride guarantee a high level of adhesion between the outer layer of PE (or PP) and the epoxy resin coated steel pipe.
