Charter Plastics has developed a broad selection of polyethylene pipe in the pressure and sizes to meet your project requirements.

The following Chart will help you to select the Right Pipe for your application.

Product Family:
From the Chart shown below or from the Webpage Tab labeled “Pipe”, clicking on any of these Product Families will take you to the products specific to that family. There you will find the description, sizes and specification for those products.
The Product Families include:

Material Designation:
There are three different polyethylene resin designations noted and one polypropylene:

  • PE 2708 – MDPE (Medium Density Polyethylene) is for Gas Applications only
  • PE 4710 – HDPE (High Density Polyethylene) is the Standard for all HDPE applications
  • PE – Polyethylene (Non-Pressure rated material for low pressure irrigation systems only
  • PP-RCT – Polypropylene Random Crystalline Temperature

Application: 
You can identify the appropriate Product Family based on your end-use application. If you do not see your application, please contact Charter Plastics HDPE Sales at 814.827.9665.

ASTM: 
Indicates the ASTM Standard to which the pipe is produced.

  • ASTM D2239 – SIDR
  • ASTM D2737 – CTS
  • ASTM D3035 & ASTM F714 – IPS
  • ASTM F714 – DIPS
  • ASTM D2513 – CTS & IPS (gas only)
  • ASTM F2389 -  Polypropylene only

Sizing System:
Polyethylene pipe is produced to four different sizing systems

  • SIDR – Standard Inside Dimension Ratio
  • CTS – Copper Tube Size
  • IPS – Iron Pipe Size
  • DIPS – Ductile Iron Pipe Size

The sizing systems correspond to specific ASTM standard and on how you plan to join the pipe.

The Polypropylene PP-RCT pipe is produced in metric pipe sizes.

Pipe Size:
Pipe size available for a given ASTM and Sizing System are shown.

Joining:
This section calls out the recommended Joining method for a given ASTM and Sizing System.

Color Coding

When you click on a Product Family, you may find that some pipes are available in different colors. Typically, Charter Polyethylene pipe is produced in black, but for specific products, color coding is available.

The color coding is based on APWA Guidelines that identify end use application by color.

This makes for easy visual identification of the end use application which is beneficial to distributors, installers and asset owners.  

Charter offers two types of color coding for polyethylene pipe:

Shell: A solid color outer shell with a natural (white) core
Striped: Black pipe with three evenly spaced stripes running the length of the pipe

  • Charter CTS and IPS pipe have 3 evenly spaced colored stripes
  • Charter DIPS Pipe have 3 pair of evenly spaced stripes which helps easily identify DIPS
