HDPE solid wall pipes for underground cable protection
BRIEF DESCRIPTION
High density polyethylene (HDPE) pipes with a solid wall profile, internally and externally smooth, black with/without red coextruded stripes on the external surface, connectable by buttfusion welding (verified according to ISO 13953) in order to be suitable also for the execution of trenchless installations (HDD, Pipe Bursting …)
In order to ensure the normal operation of the system with cable temperatures up to 80ºC and short-circuit temperatures (not exceeding 5 seconds) up to 160ºC, the mechanical characteristics of the pipe meet the requirements of the following standards:
- CEI EN 61386–1–24 (from ɸ 25 up to ɸ 250 mm)
- IEC 62067: Verification of the mechanical characteristics of HDPE conduits for cable with nominal voltages from 150 to 500 kV, before and after thermal aging
- ENA TS 12-24: verification of crushing strain resistance at 50ºC (Group 2) and 75ºC (Group 1)
Range of diameters included:
- all those required by CEI EN 61386, in various thicknesses for the different classes of ring stiffness
- all sizes up to ɸ 1200 mm, with reference to the SDR classes standardized by EN 12201-2
