What is HDPE?

HDPE, or high-density polyethene, is a kind of thermoplastic material. It is formed of hydrogen and carbon atoms that are connected to generate methane gas, which is afterwards changed into ethylene, and with the use of pressure and heat, it gets converted into polyethene. There are numerous HDPE pipe dealers and manufacturers worldwide, but you must find one that is trustworthy and helps gain huge benefits. 

Different Types of HDPE Pipes

Based on the highest-pressure withstanding ability, HDPE pipes are categorized into several pressure grades called PN grades. They are:  

• PN 2.5 – maximum pressure capability (2.5 bar) 

• PN 4 – maximum pressure capability (4 bar) 

• PN 6 – maximum pressure capability (6 bar) 

• PN 10 – maximum pressure capability (10 bar) 

• PN 16 – maximum pressure capability (16 bar) 

• PN 20 – maximum pressure capability (20 bar) 

• PN 25 – maximum pressure capability (25 bar) 

Also, based on the type of HDPE pipe material, these pipes are classified into the following types:  

• PE 63 (used as medium pressure piping systems) 

• PE 80 – gas pipe, drinking water pipe, sewers, outfall pipes, and industrial piping system

Engineers, contractors, and customers are quickly adopting HDPE pipe and fittings for a wide range of industry applications, including municipal, industrial, energy, geothermal, marine, mining, landfill, HVAC, gas, oil, mining, and agricultural applications.

High-density polyethylene (HDPE) pipe is strong, long-lasting, flexible, and light. Due to the seamless nature of the pipe system, HDPE offers a zero-leak rate when fused together. Because it is non-toxic, corrosion and chemical resistant, has a long lifespan, and is suitable for trenchless installation methods, HDPE pipe has a lower environmental impact.

The following are some of the distinct advantages of specifying the use of HDPE pipes and fittings:

Handling

When compared to other pipe materials, HDPE pipe is much easier to handle and install, allowing for significant cost savings and ROI. Because high-density polyethylene is about one-eighth the density of steel, installation does not necessitate the use of heavy lifting equipment. The flexibility of HDPE allows for bending without the need for additional fittings, and it can be easily installed in continuous lengths over uneven terrain.

Reduced installation costs

Because of its seamless capabilities and flexible characteristics, HDPE is particularly well suited for trenchless applications, allowing for a bending radius of 20 to 25 times the pipe's outside diameter. Directional boring, ploughing, river crossings, pipe bursting, and slip lining are all common applications for HDPE. High-density polyethylene pipe systems require fewer fittings and can be welded into seamless, leak-free pipe runs, saving time and money.

Heat-fused joints

HDPE pipe can be heat fused together to form a joint that is as strong as or stronger than the pipe while remaining virtually leak free. Butt fusion and electrofusion are the most common and dependable welding techniques used to join high-density polyethylene pipes, and they provide significant installation advantages over traditional pipe materials.

Corrosion and Chemical Resistance

Unlike traditional pipe materials, HDPE pipe will not rust, corrode, tuberculate, or support biological scale or growth. It also has superior chemical resistance. HDPE outlasts many more expensive piping materials in mining, dredging, and similar applications, and has excellent corrosion resistance to corrosive acids, bases, and salts. HDPE is also resistant to many organic substances because it is unaffected by bacteria and fungi.

High Flow Characteristics

As HDPE pipes are smoother than steel, cast iron, ductile iron, or concrete, a smaller diameter HDPE pipe can produce an equivalent volumetric flow rate at the same pressure. At high flow rates, it has less drag and a lower tendency for turbulence. The superior chemical resistance and non-stick surface characteristics of HDPE virtually eliminate scaling and pitting, preserving the pipe system's excellent hydraulic characteristics throughout its service life.

  The larger diameter pipes are typically employed in high-demand situations such as firewater, municipal water mains, industrial effluent conduits, and stormwater drainage systems. They are also used in outfall lines for wastewater treatment plants and as conduits for larger cables.

Each size category is designed keeping in mind the requirements of pressure, flow rate, and environmental factors of the intended application. By matching the correct HDPE pipe size to its use, engineers and contractors can optimize performance and extend the lifespan of their piping systems.

How Dimension and Diameter are Interrelated in HDPE Pipes

Dimension and diameter are interrelated concepts in the context of HDPE pipes. The inside diameter dictates the flow capacity of the pipe, while other dimensions such as wall thickness contribute to the pipe’s pressure rating and overall strength. Understanding these relationships is crucial when selecting the appropriate pipe size for your specific requirements.

Understanding the Critical Role of SDR in HDPE Pipe Selection

The term Standard Dimension Ratio (SDR) is a crucial concept in HDPE pipe engineering, denoting the ratio of the pipe’s outside diameter to its wall thickness. Understanding SDR is essential because it directly affects the pipe’s ability to handle pressure and flow rates. Moreover, a lower SDR signifies a thicker wall, equipping the pipe to endure higher pressures, which is pivotal for safe and efficient fluid transport.

SDR can be determined by dividing the outside diameter of the pipe by the wall thickness. The result of this calculation gives you the SDR, which is a dimensionless number. This simple yet powerful formula helps engineers and installers to categorize pipes based on their pressure handling abilities and ensures that the correct type of pipe is used for each unique application.

• Example: If an HDPE pipe has an outside diameter of 8in and a wall thickness of 0.4in, the SDR is 20 (8in ÷ 0.4in). 

The SDR value of an HDPE pipe directly correlates with its maximum safe operating pressure. As stated earlier, pipes with lower SDR values are able to withstand higher pressures, which is a vital consideration in the selection process for projects that involve high pressure or critical applications. Choosing a pipe with an inappropriate SDR could lead to system failure, safety risks, and costly repairs.

How to Choose the Right HDPE Pipe Size
