PE-Xc

EVOH oxygen barrier pipe for heating and domestic water

Composition
 
Components
1Inner pipe in PE-Xc (cross-linked high density polyethylene)
2Layer of adhesive connecting the inner pipe to the EVOH-oxygen barrier pipe
3EVOH-oxygen barrier pipe
4Layer of adhesive connecting the inner pipe to the EVOH-oxygen barrier pipe
5External pipe in PE-Xc (cross-linked high density polyethylene)
Info
 

CONSTRUCTION FEATURES AND PERFORMANCE
The PE-Xc polyethylene pipe is crosslinked via an electronic method, and owing to the arrangement of the 5 layers, the EVOH oxygen barrier is protected from mechanical damage and, at the same time, the thickness of the inner PEX layer is always equal to that of a 3-layer pipe, having the same size.
The several inspections and quality controls ensure maximum safety over time, as proven by the SKZ certification, accredited and certified institution in Europe for quality assurance monitoring for plastic material industrial sector.

REGULATORY COMPLIANCE
The PE-Xc pipe with EVOH oxygen barrier complies with DIN 16892, DIN 16893, UNI EN ISO 15875-2 standards and SKZ certificate.

CONDITIONS OF USE ACCORDING TO THE APPLICATION CLASSES PURSUANT TO UNI EN ISO 15875-1 STANDARD (SEE TECHNICAL ATTACHMENTS).
