Engineered Polyethylene Tank Systems – Components
Engineered Polyethylene Tank Systems – ComponentsWhen it comes to liquid process and storage, engineered polyethylene tanks offer unparalleled versatility across industries. From potable water to industrial chemicals, these tanks are built to handle a diverse array of applications. However, selecting the right material and fittings is crucial to ensure performance, durability, and cost-effectiveness.
Material Matters
Polyethylene tanks are primarily crafted from two types of resins: Linear Polyethylene (LPE) and Crosslinked Polyethylene (XLPE). While XLPE is often assumed superior, LPE actually offers better overall chemical resistance, similar physical properties, and sufficient temperature tolerance for most applications. LPE is also NSF 61-rated, making it the go-to material for high-purity applications like pharmaceuticals and food processing. Moreover, LPE tanks are recyclable, reducing environmental impact—a growing priority in today’s markets.
Process Fittings: A Critical Decision
The right process fittings can make or break the performance of a tank system. Options range from economical bulkhead fittings to robust welded couplings. Each fitting style presents unique benefits and limitations:
- Bulkhead fittings are cost-effective and easy to install but may require frequent gasket replacements.
- Welded couplings provide unmatched durability and chemical compatibility, ideal for heavy-duty applications.
- Spin-weld fittings offer a low-cost solution but are best suited for light-duty and top-mounted applications.
Advanced options like SUMO or IMFO fittings, integrated during the molding process, reduce leakage risks and maximize drainage but come with fixed locations and limited sizes.
Making the Right Choice
Selecting the optimal tank system goes beyond choosing the right resin or fittings. It requires an understanding of material properties, application needs, and the long-term demands of the system. Collaborating with an experienced tank supplier ensures a tailored solution, balancing performance, safety, and lifecycle cost.
Engineered polyethylene tanks and components are investments in operational reliability. By staying informed about material innovations and partnering with trusted providers, businesses can achieve a seamless, high-performing tank system.

This white paper delves into the dynamic journey of manufacturing rotationally molded polyethylene tanks over the past four decades. Unlike tanks crafted from traditional materials such as mild steel, stainless steel, and fiberglass, the realm of rotationally molded polyethylene tanks is a relatively youthful domain.
If you are looking for quality, low tooling costs, high tensile strength, uniform wall thickness, and a single, seamless one-piece construction in a tank or other product, then a rotationally molded part is your best solution.
About 35 years ago, Peabody Engineering did a study in cooperation with California State University Long Beach Engineering Structures Lab to design a viable seismic restraint system for our polyethylene tanks.
With more than 40 years in the plastic tank business, you would be hard pressed to find an application we haven’t seen before. When it comes to building polyethylene tanks for custom applications, there are always unique design considerations. Our whitepaper includes important factors when configuring and specifying a special application storage tank.
When it comes to maximizing the life cycle of your storage tank assets, and your ROI, it’s natural to choose the most cost-effective, durable construction material for your application. For those reasons and more, polyethylene for commercial storage tanks is ideal for applications storing a wide range of liquids. But what is the expected life cycle of a polyethylene tank?
