Difference between HDPE and Polyethylene Tanks

Difference between HDPE and Polyethylene Tanks


Polyethylene has several scientific and commercial names according to its varying density. IUPAC or the International Union of Pure and Applied Chemistry nomenclatures are used interchangeably to indicate polyethylene or polymethylene. In other words, PE is produced by manufacturers in concentrations whose feature is heavily influenced by the extent and type of side branching from the polymer chain. 

Tanks made of polyethylene are typically classified as molded or fabricated. HDPE, or high-density polyethylene, derives polyethylene tanks from flat sheets. Like steel tanks, specialized equipment is used to weld sheets together and build sidewalls and roofs that meet regulatory requirements. HDPE's rigidity and crystalline structure make it denser and the most commonly used material to build tanks, drains, and water pipes.

Benefits of HDPE Tanks

HDPE tanks are one of the best materials – they are easy to install, work with, and resist oil, diesel, fuel, oils, acids, and other chemicals. A food-grade plastic HDPE does not leave taints, and residues like other tanks and water remain fresh unhindered. Overall, these tanks enable safe handling and storage without the risk of leakage or spoilage.


HDPE tanks are durable and resistant to harsh environments such as UV exposure, high impacts, and extreme temperatures. Furthermore, they are resilient to cracking, peeling, and embrittlement, ensuring structural integrity for a long time.


Compared to other materials like concrete and steel, HDPE tanks are lightweight and can be handled easily. These tanks make transportation, installation, repositioning, and maintenance extremely easy.


With excellent resistance to impact, HDPE tanks are the most suitable for installation in craggy areas or places where accidents are frequent. External forces do not act on them as quickly, making them buoyant to cracking or damage.


HDPE tanks are designed with precision, ensuring they are leakproof when installed or maintained. This minimizes the risk of pollution, environmental hazards, and unwanted spills. Besides, they are manufactured to meet custom design specifications, including capacity, size, and shape; HDPE tanks can fit into various spaces and layouts. 


Because of its non-toxic nature, HDPE tanks can be used for a variety of purposes. Thus, product integrity and safety are well-maintained where hazardous chemicals, for instance, do not seep into the contents accidentally. 


Characteristics of Polyethylene Tanks

Polyethylene tanks also share the same features and benefits as those of HDPE tanks. They are leak-resistant, display versatility in production, and are easy to install and maintain while also being resistant to extreme temperatures and situations. They are also resilient to natural disasters such as earthquakes while being non-corrosive in nature. Additionally, polyethylene tanks are made of inert materials and do not react when they come in contact with other substances. 


These tanks may be extremely cost-effective compared to other tanks but can be highly susceptible to impact damage. They do not perform long outdoors, primarily due to prolonged UV exposure. Besides, it also comes with temperature limitations.
