A water main is a critical part of a city’s utility infrastructure. It transports clean water from a water treatment plant to neighborhoods that need it.
Proper maintenance and inspections can minimize the risk of leaks or infrastructure deterioration. It helps prevent water contamination that can threaten public health.
PVC Pipes
Since they have been around for so long, made of polyvinyl chloride, PVC pipes have supplanted metal piping in both residential and business settings. They are corrosion-resistant and long-lasting. They are, therefore, a sensible option for underground water supply pipe.
The smooth surfaces of PVC pipes encourage water flow and raise pressure, lowering energy consumption and pumping expenses. They are also easy to maintain and work well in various temperatures and pressures. They also provide excellent resistance to shock, abrasion, and chemical corrosion.
In addition, PVC pipes can be easily recycled several times without losing their technical properties. These pipes are also non-toxic and do not release harmful fumes when burned.
While a few ill-informed allegations persist about the safety of PVC, the facts show that this pipe is safe and durable. It’s essential to accurately measure the ID, or inner diameter, of your PVC pipes before using them in new construction or repairs. To do this, place a ruler or caliper against the inside edge of the pipe. It should be done at multiple points on the pipe to account for any variations in size. Then, you can choose the proper fittings for your project. The PVC sizing chart can help you determine the correct ID for your needs.
HDPE Pipes
High-density polyethylene pipes are flexible piping systems that can transfer fluids and gases. They commonly replace aging concrete or steel mains pipelines and are highly effective at handling large amounts of pressure. In addition, they are waterproof and resistant to chemical exposure.
Aside from water, HDPE pipes are also used for wastewater management and transporting slurry in businesses. They are great for industrial and residential applications because they withstand rough handling, traffic loads, and changing underground conditions. They are also made of food-grade virgin material safe for potable water distribution.
The flexibility of a HDPE pipe also makes it easier to install. It eliminates the need for joints and reduces the risk of leaks by bending to accommodate curves and contours of the ground. It can be essential in rocky or hilly terrains where pipes would otherwise be dug by hand.
Additionally, HDPE is often used in directional boring, plowing, river crossings, pipe bursting, and slip lining. It can perform exceptionally well in mining, dredging, and similar activities, outwearing many more costly piping materials while offering excellent corrosion resistance to corrosive acids, bases, and salts. Additionally, it is incredibly lightweight compared to concrete and steel pipes, reducing labor requirements for installation.
Copper Pipes
Due to their widespread acceptance and effectiveness, copper pipes have become a preferred choice for water supply lines. They’re durable and have excellent thermal and electrical conductivity, allowing fast hot and cold water delivery. They also resist corrosion, and they’re easy to install. However, they can be more expensive than other piping materials.
While copper is a safmaterour plumbing, it could be better in acidic or salty groundwater areas. It can deteriorate over time, resulting in copper pinhole leaks. To reduce this risk, plumbers often sheathe copper pipes in synthetic sleeves.
There are several different types of copper pipe, categorized by their thickness. The two most common types of copper piping are type L and type M. These are recognizable by their blue or red markings. Type L copper pipe is thicker than type M and is commonly used for indoor plumbing. Type M copper pipe, on the other hand, has a thinner pipe wall and is more affordable.
Regardless of the type of copper you choose, it’s essential to have professional copper pipe installation services when you need repairs or replacements. It will help minimize damage to your property and ensure that your water pipes are in good condition for years. It’s also important to be intentional about your fittings and couplings, as they could impact how long your water pipes last.
Ductile Iron Pipes
Ductile iron pipes are a vital part of reliable water delivery systems. They offer strength and durability for transporting raw and potable water, sewage, and process chemicals. In addition, they can be safely buried in deep trenches and rocky soils. Their combination of chemical analysis and heat treatment creates the desirable mixture of strength and flexibility. It enables ductile iron pipes to resist damage during shipping and handling and the stresses of operating conditions such as water hammer, frozen ground, highway traffic, and shifting expansive or unstable soils.
A recent study showed that DI pipes exhibit fewer failure modes than other pipe materials. That means less frequent repairs, reduced operating costs, and more dependable performance for generations.
Unlike other pipe materials, ductile iron pipes have a moderate and dependable coefficient of thermal expansion. It prevents the formation of stress cracks due to changes in pressure or temperature, which is often a cause of other pipe failures.
In addition, ductile iron pipes have a superior tensile strength. The chart below shows that flexible iron pipes have more than 24 times the tensile strength compared to HDPE pipes of the same size and pressure class. As a result, their ability to withstand the forces of internal hydrostatic pressure and water hammer is far greater than that of other materials such as PVC or HDPE.
