Subduct

High Density Polyethylene (HDPE) Pipe for Optical Fiber Cables Application

Technical Specification

GENERAL

The raw material of Polyethylene (PE) pipes is classified as High Density Polyethylene (HDPE) PE-100 compound with ultra violet (UV) resistant, corrosion resistant and nonconductive. PE-100 material is an excellence balance between 3 (three) main properties: Stress Cracking, Pressure and Impact Resistances, make it safe to install the pipes at severe conditions such as no dig technique or sandless trench installation. CCSI HDPE pipes are designed to be flexible, lightweight, durable, non-toxic, easy to install and smooth in inner and outer layer with uniform thickness, strong and safe joining systems. These product application is for direct underground buried installation by open continuous trenching, plowing, directional boring, pulled into existing duct or conduit and also ideal for cable jetting installation methods.

REFERENCE STANDARDS

The offered HDPE subduct pipes complies to the STEL L-039-2008 version 2.2 Spesifikasi Telekomunikasi Pipa HDPE Untuk Kabel Serat Optik

CONSTRUCTIONS

PIPE MATERIAL

High Density Polyethylene (HDPE) PE-100 class

– Natural and black color with excellent weathering and ultra violet resistance

– Excellent mechanical properties

– The third generation of pipes grade material designation which have long term hydrostatic strength in 50 years service lifetime

– Resistance to Slow Crack Growth and Rapid Crack Propagation (RCP)

– Compliance with FDA regulation 21 CFR177.152

Additive and Colorant Masterbatch

– The resin carrier and additive is the same grade of HDPE material

– The additive and colorant imparting other properties into pipes and resulting more advantage

– Designed for outdoor application with highly resistance environmental effected by weather and ultraviolet sunlight
