Advantages of Copper Pipe

Very Durable
Copper piping is extremely durable. Once copper piping is installed in your home, you can usually expect it to last 50-70 years.

Able to Withstand Temperature Extremes
If you have dealt with frozen water pipes in the past and don't want to face that problem again, copper piping is a great way to prevent frozen pipes in your home. Compared to many other piping materials, copper pipes are far better at withstanding hot and cold temperature extremes.

Environmentally Friendly
If you have purchased an older home and want to make it environmentally friendly, copper plumbing pipes are a great way to help the environment when doing a whole house repiping project. When they are manufactured, copper pipes release far fewer chemicals and emissions into the environment. As an added bonus, copper pipes can be recycled upon being replaced.

Very Lightweight
Copper piping is very lightweight, making it great for plumbing repairs throughout your home. Because it is very flexible, our plumbing pros can install these pipes almost anywhere in your home, and can in fact extend it over long distances if needed.

Resist Corrosion
If your home has had problems with slab leaks in the past due to corroded pipes, copper piping can solve this problem. Virtually corrosion-resistant, you can have us install copper pipes in your home and be rest assured your slab leak problem will come to an end.

Fire Resistant
If you have ever had a burst pipe in your home due to a furnace that breaks down on a cold winter day, you'll be glad to know that copper pipes have high thermal ratings, making them very resistant to fire.

They Don't Contaminate Water
Finally, copper pipes do not contaminate water, meaning you and your family will not have rust in your water whenever you fill up a cup at your faucet.

Applications of Copper Pipe

Plumbing Systems
Copper pipes are widely used in plumbing for home and buildings in general. They are suitable to be used in water supply lines because they possess high temperature tolerance, are are resistant to corrosion and bacterial formation ensuring clean and safe water supply.

HVAC Systems
In the Heating, Ventilation, and Air Conditioning (HVAC) structures, copper pipes are used for refrigerant strains. Their thermal conductivity and pressure versions make it reliable for cooling and heating systems.

Gas Distribution
Copper pipes are used in distribution of natural gas and propane in homes and other commercial facilities. Their flexibility, durability and resistance to corrosion guarantee a safe and efficient supply of gas.

Refrigeration
In refrigeration systems, copper pipes play a crucial role in transferring refrigerants. Because of their high thermal conductivity and the ability to be wound into coils they are used in refrigerators, freezers and industrial cooling systems.

Fire Sprinkler Systems
Copper pipes are used for fire sprinklers due to its ability to resist pressure, heat, and corrosion and allow the system to function during an emergency.

Solar Heating Systems
Solar water heaters use copper pipe to transfer heat from solar collectors to storage tanks.

Medical Gas Systems
Copper pipes are used in healthcare facilities to supply medical gases such as oxygen and nitrous oxide as well as compressed air. Their non-reactive nature ensures that this gas is clean and free of contaminants.

Industrial Applications
Copper pipe is used in a variety of industrial applications including chemical processing and oil refining due to its ability to handle corrosion and high-pressure atmospheres

Electrical Applications
These pipes are used as earthworks for the installation of power plants and to protect power lines because of their ability to carry electricity and energy

Marine Applications
In the marine environment, copper-nickel alloy pipe is used for desalination plants, marine vessels, and offshore structures. They resist biofouling and corrosion from saltwater hence providing durability to the equipment.

Steps for Welding Copper Pipes

Measure and Cut the Pipe
Measure the copper pipe to the length you need and use a tube cutter for a clean, square cut. Tighten the cutter just enough to contact the pipe, then rotate it around until it cuts through.

Deburr and Clean the Pipe and Fitting
After cutting, deburr the pipe ends using a deburring tool to remove any sharp edges. Clean both the outside and inside of the pipe with sand cloth or a tube cleaning brush to remove any dirt and oxidation. Similarly, clean the inside of the fitting hubs thoroughly.

Apply Flux
Apply a thin layer of flux to both the pipe end and inside the fitting hub using a brush. Flux helps the solder flow smoothly and prevents oxidation during heating. Make sure the flux is spread evenly.

Assemble the Joint
Insert the pipe end into the fitting, ensuring it is properly seated. The fit should be snug and secure to facilitate a good connection when soldering.

Heat the Joint
Use a propane torch to heat the joint evenly, starting from the bottom and working your way up. This ensures the solder doesn’t drip downward. The joint is ready when the flux bubbles and the metal is hot enough to melt the solder upon contact.

Solder the Joint
Feed the wire solder into the joint. The solder will melt and flow into the joint due to capillary action, filling the gap between the pipe and the fitting. Ensure that the solder flows around the entire joint, creating a silver band that is flush with the surface of the pipe. This indicates a complete and sealed joint.

Cool and Clean the Joint
After soldering, let the joint cool without touching it. While it’s still warm, wipe away any leftover flux with a clean rag to keep the joint clean and strong.

FAQ

Q: What is the life expectancy of copper pipes?

A: Copper pipes typically last between 50 to 70 years. Their durability and resistance to common plumbing issues make them a reliable choice. However, factors like soil conditions, stray electrical currents, and water pH can affect their lifespan.

Q: How to bend a copper pipe?

A: Straighten out the copper pipe or tube.
Use duct tape to close one end of the copper pipe.
Use a funnel to fill the copper pipe with sand or salt.
Tape the other end of the copper pipe.
Bend the pipe until the desired curve is attained.
Remove the tape and allow the sand or salt to flow out of the pipe.

Q: What size copper pipe is used in homes?

A: In residential plumbing, 1/2-inch and 3/4-inch copper pipe are the most common sizes. Larger sizes, like 1-inch, are sometimes used for main water lines, especially in homes with more fixtures.

Q: Can you bury copper pipe in dirt?

A: Yes, copper pipe can be buried in the ground in most cases. Copper is generally resistant to corrosion in many soil types and underground environments, making it suitable for direct burial in many situations. However, certain soil conditions can cause corrosion, and in these cases, protective measures like sleeving may be necessary.

Q: What is the best method for connecting copper pipes?

A: In most settings, plumbers still prefer soldered connections when fitting copper pipes. They apply pipe flux and heat the joint with a torch, enabling the solder to flow between the fitting and the pipe to create a watertight seal.

Q: Does green on copper pipe indicate a leak?

A: Yes, green discoloration on copper pipes, also known as patina or oxidation, can indicate a leak or other plumbing issues. While the green itself isn't harmful, it's a sign that the copper has been exposed to moisture and may indicate a leak or other source of dampness.
