Cross-linked high-density polyethylene pipe COBRAPEX

The COBRAPEX pipe is made of high-density polyethylene and is chemically cross-linked (silane cross-linking), suitable for use in both heating systems and systems for food use. The expected service life is 50 years. The main steps of the production process are:

• Receipt of raw materials
• Extrusion
• Cross-linking
• Post cross-linking controls
• Packaging
• Management of non-conformities and non-conforming material

The cross-linking of the COBRAPEX pipe is of type “b” (PE-Xb); this process allows the chemical structure of the material to be modified, resulting in:

• increased maximum operating temperature (95°C or 110°C for short periods);
• reduced deformation under load;
• increased chemical resistance;
• increased UV resistance;
• increased resistance to abrasion and impact;
• improved thermal memory characteristics
