Water Pipe

High Density Polyethylene (HDPE) Pipe for Water Supply 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. This material are design to withstand the long term pressure with minimum required strength (MRS) 10Mpa, applying safety factor 1,25 with the result that the thinner pipe wall thickness in particular size is progressively less as the change is made and covered the whole range of pressure, this can be significant cost saving. 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 using thermal fusion or mechanical compression. The pipe product application is for water supply and also use in variety installation in the civil, agriculture, municipal, mining and industrial sectors. The installation method is recommended for direct underground buried installation by open continuous trenching, other method are possible depending the pipe application.

REFERENCE STANDARDS

The offered HDPE water pipes complies to the ISO 4427- Plastic Piping Systems (Polyethylene pipes and fittings for water supply) and also refer to the Standard Nasional Indonesia SNI-06 4829-2005 Pipa polietilena untuk air minum.

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 RoHS and FDA regulation 21 CFR177.152

 Colorant Masterbatch

– The resin carrier masterbatch is the same grade of HDPE material and heavy metal free

– 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

CROSS-SECTIONAL DRAWING OF WATER PIPE

The pipes manufactured in the range of dimension are common in term of Standar Dimension Ratio (SDR), that is mean outside diameter divided by wall thickness. The relationship between SDR and wall thickness if more thinner wall thickness increase SDR and thicker wall thicknes is lower SDR.
