HD Supply Waterworks is one of the nation’s largest distributors of high-density polyethylene (HDPE) pipe. Polyethylene pipe is tough, durable, flexible, corrosion free and chemical resistant. Its unique properties allow for it to be used in a broad range of applications including municipal, industrial, landfill, geothermal, mining, and more.
Features and Benefits of Polyethylene Pipe: (clips pulled from Plastic Pipe Institute)
- Life Cycle Cost Savings: The smooth inside surface of PE pipe maintains its flow characteristics, and feat fusion joining eliminates leakage.
- Leak Free, Fully Restrained Joints: PE heat fusion joining forms leak-free joints that are as strong as, or stronger than, the pipe itself.
- Corrosion & Chemical Resistance: PE pipe will not rust, rot, pit, corrode, tuberculate or support biological growth. It has excellent chemical resistance and is the material of choice for many harsh chemical environments.
- Fatigue Resistance and Flexibility: PE pipe can be field bent to a radius of about 30 times the nominal pipe diameter or less depending on wall thickness (12” PE pipe, for example, can be cold formed in the field to a 32’ radius). This eliminates many of the fittings otherwise required for directional changes in piping systems.
- Seismic Resistance: The toughness, ductility and flexibility of PE pipe combined with its other special properties, such as its leak-free fully restrained heat fuse joints, make it well suited for installation in dynamic soil environments and in areas prone to earthquakes.
- Construction Advantages: PE pipe’s combination of light weight, flexibility and leak-free, fully restrained joints permits unique and cost-effective installation methods that are not practical with alternate materials. Installation methods such as horizontal directional drilling, pipe bursting, sliplining, plow and plant, and submerged or floating pipe, can greatly simplify construction and save considerable time and money on many installations.
- Durability: PE 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 PE pipe industry estimates a service life for PE pipe to be, conservatively, 50-100 years provided that the system has been properly designed, installed and operated in accordance with industry established practice and the manufacture’s recommendations.
- Hydraulically Efficient: The internal surface of PE pipe is devoid of any roughness which places it in the “smooth pipe” category, a category that results in the lowest resistance to fluid flow. For water applications, PE pipe’s Hazen Williams C factor is 150 and does not change over time.
- Temperature Resistance: PE pipe’s typical operating temperature range is from 0°F to 140°F for pressure service. However, for non-pressure and special applications the material can esily handle much lower temperatures (e.g., to - 40°F and lower) and there are specially formulated materials that can service somewhat higher temperatures.
