Normally available in two grades. 300 grade and 500 grade. the higher number denotes the density of the material and can improve on performance. The majority of HDPE is available in either black or white although 500 grade sheet is available in a range of colors.

The safe peak pressure or allowed total pressure for HDPE pipe is 1.5 times the pipe's pressure rating for recurring surge and 2.0 times the pipe's pressure rating for occasional surge.

What are the failures of HDPE water pipe? ›

Some of the most common ways for HDPE pipes to break are ductile overload, non-ductile or pinhole cracks, and oxidative degradation [52] ; for example, leaks at CI pipe sleeve connections; HDPE tee cracks, connector cracks, and pipe cracks; PVC pipe cracks, pipe corrosion, and tee leaks [49].

HDPE pipe is well-suited for potable water supply applications. Beneficial properties of HDPE piping systems include: Leak-free Fused Joints. Fused joints eliminate potential leak points and reduce installation time.

HDPE as a petrochemical derivative

One of the main factors that influences the HDPE market is the price of the raw material ethylene. Ethylene is a petrochemical product that is significantly affected by global oil prices and supply and demand dynamics.

Cost: PVC pipe is generally less expensive than HDPE pipe, which can make it an attractive option for applications with tighter budgets. Rigidity: PVC pipe is more rigid than HDPE pipe, which makes it a good choice for applications that require high stiffness, such as water mains or sewer lines.

HDPE is available under trade names of HiTec, Playboard, King Colorboard, Paxon, Densetec, King PlastiBal, Polystone, and Plexar.

PEX pipe is made from high density polyethylene (HDPE), PEX is the term for the cross-linking process that improves the chemical and temperature performance of the polymer and provides flexibility and additional strength.

HDPE is a type of PE pipe. However, HDPE pipes are more durable than other PE pipes because they come with high melting and impact points. HDPE pipe is tough, resistant to chemicals, resistant to corrosion, and light in weight.

The Cons of Utilizing HDPE:

It is high flammability, sensitivity to stress cracking, inability to be biodegradable, inability to be composted, lack of resistance to oxidizing acids, lack of resistance to chlorinated hydrocarbons, and its high thermal expansion.

Due to its high density, HDPE is a crystalline material and when a high tensile stress is applied the material will stretch and yield before ductile failure, but at low tensile stress, the material will fail suddenly with a smooth break typical of brittle failure. This is known as environmental stress cracking.

At what temperature does HDPE degrade? ›

Aigbodion et al. [56] conducted an analysis of HDPE pellets thermal stability and, similarly to the results obtained in this research, concluded that the main thermal decomposition of HDPE occurs at 487.5 • C when temperature is elevated at 20 • C/min rate in N 2 atmosphere.

In lieu of calculations, AWWA states that for an embedment soil with an E'of 1000 psi and no surface water, HDPE pipes with DR's ranging from 7.3 to 21 can be safely buried from a depth of 2 ft to 25 ft where no traffic load is present and from 3 ft to 25 ft where H20 live load is present.

HDPE material may be used for above ground pipeline installations if it is protected from UV (ultraviolet) and if it meets the hydrostatic pressure requirements of the design.

A significant limitation for polyethylene pipe in these applications is its temperature capability. Typically, polyethylene pipe can be safely used at temperatures up to 60°C (140°F). Projects that involve higher temperatures have historically required alternative materials.

Although PVC and HDPE are both common piping materials, HDPE is the superior option for most piping applications. Industries that rely on HDPE pipes include energy, natural gas distribution, mining, municipal, and communications.

PE100 has advantages over PE80 at low temperatures since it is extremely crack resistant down to -30°C. MDPE pipe is only made from PE80 material and HPPE pipe is only made from PE100 material. HDPE pipe can be made from either PE80 or PE100.

PE100 also has a higher strain hardening modulus than PE80, suggesting that the former is better in the resistance to deformation. In addition, viscous stress and quasi-static stress of PE100 are higher than those of PE80. However, PE80 has a better resistance to relaxation.

Raw materials used in the polyethylene pipe and fitting productions are classified with MRS (Minimum Required Strength) according to mechanic resistance criteria. MRS is the resistance value of material against inner pressure at 20 °C for 50 years.

What is stronger than HDPE? ›

UHMW (Ultra High Molecular Weight) polyethylene plastic has one of the highest impact strengths of any thermoplastic and has excellent abrasion resistance and tensile strength. UHMW has the highest impact strength of all the polyethylenes and the material will outwear carbon steel 10 to 1 in some applications.

HDPE pipe sizes also vary in thickness, diameter, and length. The common types are HDPE 80 and HDPE 100. HDPE 80 pipes transport gas raw materials, while HDPE 100 transfers liquid items like oil and water. HDPE 100 pipes come with a higher density for robustness and thinner, rigid walls that offer operation stability.

LDPE is softer and more flexible than HDPE. It also has a lower melting point (115° C) and is more transparent.

HDPE pipe fused joints are self restraining and costly thrust restraints or thrust blocks are not required.

HDPE is insoluble in water and most organic solvents, although some swelling may occur on immersion in the latter. HDPE is an excellent electrical insulator. LDPE is a soft translucent solid which deforms badly above 75º C. Films made from LDPE stretch easily and are commonly used for wrapping.

From this chart it can be seen that HDPE has excellent resistance to chlorinated water at 20 degrees and conditional or limited resistance at 60 degrees. HDPE is not used in highly chlorinated environments such as swimming pools and there are specific guidance for chlorinated water up to 3500 ppm.

High Density Polyethylene (HDPE) is a non-hazardous material and it's over exposure by short term or long term inhalation does not cause any harmful health effect.

Copper pipes remain popular among plumbers and homeowners alike because they are corrosion-resistant and best suited to protect the quality of the water. Copper pipes are able to handle high water pressure and are tolerant of both hot and cold water temperatures.

HDPE has a higher density as opposed to the previous one. It is used for milk jugs, household cleaner containers, juice bottles, shampoo bottles, cereal box liners, and more. Similarly, to what was mentioned earlier, this plastic is considered safe to use and be in contact with food and beverages.
