VPL HDPE potable water, sewer and industrial pipes are manufactured for use in the municipal & industrial markets. VPL HDPE Pipes are WRAS certified for Drinking Water Applications.
VPL HDPE potable water pipe designed for use in the municipal and industrial markets provides and monolithic, corrosion and leak free piping system for transporting potable water and other fluids for industrial applications. HDPE pipe is an excellent choice due to its proven track record of providing longevity and reliability in fluid piping systems. With multiple manufacturing locations, the end user is assured of receiving superior products combined with maximum service. VPL HDPE pipes to these markets are quickly being adopted as the better performing material of choice due to its improved properties compared to conventional piping materials like PVC or ductile iron. VPL services this important market because HDPE pipe provides a leak free reliable water system that protects our precious water resources, especially in those arid regions where water is scarce.

BENEFITS - HDPE PIPE
There are several distinct advantages of PE pipe that provide important benefits for sewer and wastewater applications.
These benefits are listed below.
1. Heat Fused Joints - Benefits
- HDPE pipe’s fused joints do not leak, eliminating infiltration and inflow problems experienced with alternate pipe joints.
- HDPE pipe can be heat fused together to form a joint that is as strong or stronger than the pipe itself and is leak-free. This eliminates the potential leak points every 10-20 feet as found with PVC and Ductile Iron bell-and-spigot connections.
- The Life Cycle Cost of HDPE pipe differs from other pipe materials because the “allowable water leakage” is zero rather than typical leakage rates of 10 to 20% for PVC and Ductile Iron.
- HDPE pipe fused joints are self-restraining and do not require costly thrust restraints or thrust blocks.
2. Chemical Resistant - Benefits
- PE is highly resistant to the wet, hydrogen sulfide gas and the low concentration acid found in a sanitary sewer.
- PE pipe will not corrode, tuberculate or support biological growth
- To review information on PE’s resistance to various (TR-19)
- Superior chemical resistance to aggressive soils.
3. Abrasion Resistant - Benefits
- PE is abrasion resistant and is well suited for the solids environment in sewer applications.
4. Consturction Advantages - Benefits
- The combination of flexibility and leak-free joints allow for unique and cost-effective types of installation methods that the rigid PVC and Ductile Iron pipes can’t use with bell-and-spigot connections. These alternate installation methods (Horizontal Directional Drilling, Pipe Bursting, Slip lining, Plow and Plant, Submerged or Floating Pipe, ) can save considerable time and money in most applications.
- Polyethylene pipe is produced in straight lengths up to 50 feet long and coiled in diameters up through 6 Coiled lengths over 1,000 feet are available (depending on size) providing low cost installations.
- Polyethylene is about one-eighth the density of steel and does not require the use of heavy lifting equipment for installation.
5. Flexible and Fatigue Resistant - Benefits
- HDPE pipe is flexible and can be bent as shown in the PE For example, the minimum bending radius for a 12-inch HDPE IPS DR 17 pipe is 27 x OD = 27 x 12.75 in = 344.2 in = 28.7 ft. This can eliminate many fittings required for directional changes in a piping system where fittings and thrust blocks or restraints are required with alternate materials.
- The flexibility of HDPE pressure pipe makes it well suited for dynamic soils including areas prone to earthquake.
- HDPE pressure pipe can accept repetitive pressure surges that significantly exceed the static pressure rating of the pipe.
6. Cost Effective, Long Term and Permanent - Benefits
- Polyethylene pipe installations are cost effective and have long-term cost advantages due to the pipe’s physical properties, leak-free joints and reduced maintenance costs.
- The polyethylene pipe industry conservatively estimates the service life for HDPE pipe to be 50-100 years. This relates to savings in replacement costs for generations to come.
7. Handling - Benefits
- It is much easier to handle and install HDPE pipe the heavier, rigid metallic or concrete pipe segments, allowing for huge cost advantages in the construction process.
- Polyethylene pipe is better able to structurally withstand an impact than PVC pipe, especially in cold weather installations where other pipes are more prone to cracks and breaks.
8. Hazen Williams C Factor is 150 and Doesn't Change over Time - Benefits
- HDPE pipe has a smooth ID that does not corrode or tuberculate and maintains its flow capability over time.
- The C Factor of Ductile Iron pipe is dramatically reduced over time due to corrosion and/or 12-inch HDPE IPS DR 17 pipe is 27 x OD = 27 x 12.75 in = 344.2 in = 28.7 ft. This can eliminate many fittings required for directional changes in a piping system where fittings and thrust blocks or restraints are required with alternate materials.
- The flexibility of HDPE pressure pipe makes it well suited for dynamic soils including areas prone to earthquake.
- HDPE pressure pipe can accept repetitive pressure surges that significantly exceed the static pressure rating of the pipe.
