HDPE (High Density Polyethylene)

After its experimental preparation in the 1930s, the application in high frequency radar cables during World War II, gave impetus to its commercial production. This thermoplastic is available in a range of flexibilities depending on the production process. High density materials are the most rigid. The polymer can be formed by a wide variety of thermoplastic processing methods and is particularly useful where moisture resistance and low cost are required. Polyethylene is limited by a rather low temperature capability (200-250 F) but is manufactured in billions of pounds per year.
Vinyl acetate can be copolymerized with ethylene. The resulting product has improved transparency over homopolymerized polyethylene because of a reduction of crystallinity in the copolymer.

ADVANTAGES:

• Low cost
• Impact resistant from -40 C to 90 C
• Moisture resistance
• Good chemical resistance
• Food grades available
• Readily processed by all thermoplastic methods

DISADVANTAGES AND LIMITATIONS:

• High thermal expansion
• Poor weathering resistance
• Subject to stress cracking
• Difficult to bond
• Flammable
• Poor temperature capability

Note:

In general, high density grades of polyethylene have densities up to 0.97 g/cm^. Low density grades are as low as 0.91 g/cm^. Typically, the high-density material is more linear and consequently more crystalline. As might be expected, this higher crystallinity permits use at temperatures up to 130 C with somewhat better creep resistance below that temperature. Low density polyethylene has less stiffness than the high density type. Blends of the two types are common.

TYPICAL APPLICATIONS:

Toys, utensils, films, bottles, pipe and processing equipment. Wire and cable insulations.

What Are Advantages & Disadvantages Of HDPE Pipe Liner?

In HDPE Liner widely uses petroleum thermoplastic. If you look at this plastic under a microscope, you’ll see that it has a straight line with some branches that give it its energy/density ratio. The strong bond of HDPE piping material helps it to use for high-pressure piping. Polyethene pipes have a long and unique history in gas, oil, mining, water, and other industries. HDPE and Epoxy Pipelining both are very durable.

Due to its low weight and high corrosion resistance, the HDPE pipe industry is growing rapidly. HDPE pipe liner can perform optimally over a wide temperature range from 2200 f to +1800 f. This pipe is not good for use when the liquid temperature exceeds 1220 f (500 c).

HDPE Installation

In most cases, installing HDPE-lined pipes are cheaper and easier than installing other components. HDPE weighs much less than concrete, steel, and steel pipe, so travel costs are low and no heavy lifting equipment requires. HDPE Slip lining is usually delivered in long coils, spools, or straight tubes. Providing HDPE on spools or coils can also reduce travel costs as few deliveries require.

HDPE installation requires fewer members and installation than other pipe lining solutions, saving time and money during the installation process. Because High-Density Polythene is highly flexible, it can be bent without the need for additional joints or connectors. This flexibility allows HDPE to be installed outside of channels and in an irregular location. The joints are usually heated with heat, are as strong as the first pipe, and do not leak. 

HDPE pipe fitting is also durable, with an expected lifespan of 50 to 100 years, and is fully recycled. HDPE liner can be installed using standard methods such as pipe blasting, directional drilling, trench sealing, and micro-trenching.

Pipe blasting is a sewer system used to replace sewage, water, and natural gas, eliminating the need for traditional canal construction and associated equipment. This approach has become a viable solution for the transformation and rehabilitation of obsolete infrastructure.

HDPE Pipe Joint

HDPE pipes and fittings are connected by welding or by mechanical installation. There are two types of welding methods used to join HDPE pipes.

• Electrofusion welding: Electrofusion is a simple and fast way to permanently join individual pipes and install HDPE or pre-built components in tight areas. This method is suitable for local members.

• Butt welding: Hip welding similarly combines pipe fitting and HDPE into prefabricated parts using heat and pressure without the use of additional connectors.

HDPE Pipe Length

The production of HDPE pipes is a continuous process; pipes of any length can be manufactured. However, due to the ease of movement and grip on-site, the length of HDPE pipe is limited and is generally produced in average lengths of 6, 10, 12, 15, 24, and 30 meters. On request, a 50 and 100-metre-long HDPE pipe can be produced.

Fittings For HDPE Pipes

A complete list of HDPE pipelining inserts for any purpose is available. Standard HDPE pipe installation includes the following:

• Bent

• Elbows

• Reductions

• Branch Offices

• End Caps

• Electro Fusion Couplers

• Machine Connectors

• Traps

• Hygiene Installation

• Replacement Parts

Advantages of HDPE pipes

HDPE pipe offers several benefits over other drilling rigs such as

• Reduction Of Installation Costs

• Due To Its Flexible Shape, It Is Easy To Use On Slopes.

• Simple Joining Methods.

Common Use Of HDPE

• Plastic bottles: Most people are illegally imported in plastic containers that last longer than water bottles. HDPE is ideal for moulding applications, especially in food and beverage containers because it does not fit between bottles. Moreover, HDPE is recyclable, making it a good choice for these highly disposed of products.

• Toys: HDPE is resistant, which helps keep toys resistant to harmful effects and changes color from lightning.

• Chemical containers: With its chemical-resistant properties, HDPE is suitable for laundry, shampoo, heaters, household cleaning products, car oil, antifreeze, and recycling containers. Moreover, the strength of these bottles increases when they are colorful.

• Piping systems: HDPE pipe sheet has a higher molecular weight compared to the standard HDPEused in the examples above. Moreover, this reinforcement with its UV resistance makes it suitable for outdoor applications and plumbing. Furthermore, the pipe spacer sheet is heat resistant from -220 to 180 degrees Fahrenheit. It lasts a long time under many chemical interactions, making it useful in many industrial applications.

FAQs

Is HDPE the Same as PVC?

Both HDPE and PVC are of plastic material. However, they are not the same. In addition, HDPE is thermoplastic manufactured from petroleum, and PVC is a tough vinyl polymer. However, compared to HDPE and PVC, HDPE, due to its flexibility, high strength at high density, lack of rust, and chemical stability is a strong choice for low-pressure, low-temperature applications.

Is HDPE Pipe Safe in Drinking Water?

Yes, HDPE Liner is completely safe if you drink drinking water. Additionally, this is one of the main reasons why high-quality polyethylene pipes are widely used in the water industry and desalination plants. Moreover, the use of HDPE drinking water pipes approves by the ns’. Various antibiotics such as chlorine and chloramine are approved for use in HDPE pipes.

What are the Uses of HDPE Pipe?

HDPE or high-density polyethylene pipe is widely used to transport drinking water, sludge, sewage, chemicals, hazardous waste, and compressed gases. They use in various industries such as gas, oil, mining, water, and other industries.

Is HDPE Compatible with Nature?

Perhaps, it can consider eco-friendly as it prepares from HDPE liner to recycle plastic from type 2 post-consumer products. Moreover, it considers being the most eco-friendly plastic that does not produce harmful fumes in the environment.

Is HDPE Waterproof?

Yes, HDPE is ideal for building a waterproof foundation. In addition to aiding in water infiltration, it can also help protect the foundation from root infiltration.

Conclusion

HDPE Liner is a type of flexible plastic pipe used to transfer liquids and gas and is often used to replace old concrete pipes or large steel pipes. Made of HDPE (high-density polyethylene) thermoplastic, its high-density resistance and strong molecular bond make it suitable for high-pressure pipes.

HDPE plumbing systems are available in many applications, providing standard plumbing, fire extinguishers, sewer and gas pipelines, as well as horizontal drilling of electrical and telecommunication pipelines. Well, the above is a brief introduction to the advantages and disadvantages of HDPE pipes. I believe that after reading this article, you have a better understanding of HDPE pipes.
