High-density Polyethylene Piping Products
HDPE: the superior piping solution.
The leakproof durability and flexibility of high-density polyethylene (HDPE) pipe is the preferred material across a wide range of industries and applications.
The HDPE advantage
Leak-free joints
Optimal performance with a zero leak rate, unlike ductile iron (DI) and PVC
100-year design life
Provides superior longevity over steel, iron and copper alternatives
Lightweight/flexible
Average bend radius = 25x the outside diameter compared to DI and PVC
Fast/easy installation
Easier to install than most other potable piping systems
Extreme surge tolerance
The most surge and fatigue resistant of any water piping material
Low carbon footprint
The most environmentally friendly plastic on the market
Corrosion and chemical resistant
Built to repel acids/bases/reducing agents and won’t corrode like metallic products
Whole-life cost efficiency
The least expensive life-cycle cost of all municipal pipe materials
The HDPE leader
Strength meets flexibility
ISCO’s HDPE leadership stems from a valuable combination of in-stock HDPE pipe, fittings, and fusion equipment, industry experience, specialized expertise and service — and the clear, multiple advantages of the material itself.

Decades of experience across virtually every major HDPE application and industry
The industry’s most comprehensive in-stock selection of HDPE pipe products, fittings and fusion equipment
Value beyond products — fusion training, prefabrication, technical guidance, VE, estimating and project management support
HDPE: the sustainable pipe solution
With its long life, low carbon footprint and leak-free performance, HDPE is the sustainable choice.
Long design life
Increased durability and design life means a longer replacement cycle and lower material waste
Leakproof
Fewer leaks means less waste, reduced water loss, a lower consumption and lower chance of environmental contamination
Lower carbon footprint
Lighter weight/higher flow — less machinery to transport/install; smaller material diameter/less energy for pumping

Beyond Concrete: The Advantages of HDPE Pipe in Modern Piping Solutions
In a world where comfort often breeds resistance to change, the emergence of high-density polyethylene (HDPE) in large-diameter piping systems is revolutionizing the industry. While reinforced concrete pipes (RCPs) have long been the norm, HDPE offers a plethora of benefits from installation to long-term performance. Let’s delve into why HDPE is becoming the preferred choice over RCP.
