ASTM Wall Thickness Formulas

By White Papers

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.

Exploring the origins of ASTM wall thickness calculations, we uncover their pivotal role in shaping the landscape of manufacturing rotationally molded polyethylene tanks today.

If you’re intrigued by the advancements in molding technologies that have revolutionized the production of consistently high-quality parts, we invite you to delve deeper into the evolution of manufacturing rotationally molded tanks by downloading our white paper for a comprehensive exploration.

All You Need To Know About Rotational Molding

By White Papers

Rotational MoldingIf 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.

What is Rotational Molding?

Rotational molding is a three-stage, no-pressure, plastic molding process. During the heating stage, the mold slowly rotates in two planes (bi-axial rotation). Heat transfer causes the plastic charge inside the mold to melt and uniformly coat the interior of the mold. During the second stage, the mold moves to the cooling station, where it is cooled by air and/or water spray. In the final load/unload stage…To read more download our white paper to learn more about Rotational Molding.

Seismic Restraint Systems for Polyethylene Tanks

Seismic Restraint Systems for Polyethylene Tanks

By White Papers

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.

Based on that study, we determined that the cable and post systems that were being used as an industry standard for seismic restraint of polyethylene tanks were an ineffective and unsafe design. We decided that a new design should be developed that would safely restrain plastic tanks without the potential for damaging them. Peabody does offer a cable system for our tanks if you have budget constraints, but we strongly recommend you consider one of our three other superior designs outlined below based upon the risks associated with the cable systems noted above.

Peabody Life Expectancy

Life Expectancy of Rotationally Molded Polyethylene Tanks

By White Papers

Life Expectancy of Rotational White Paper ThumbWhen 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?  This white paper, Life Expectancy of Rotationally Molded Polyethylene Tanks, addresses the factors that can impact the poly tank life and outlines recommendations for tank care.

This white paper introduces you to Linear Polyethylene Resins (LDPE), and outlines four parameters affecting the lifespan of an LDPE tank:  its applications, its characteristics, its environmental exposures, and its care.

Learn about what makes polyethylene a superior tank solution:

  • Excellent UV inhibitors
  • Service life up to 20 years
  • Extremely chemical resistant
  • Excellent impact resistance
  • Very low maintenance
