Advantages of Custom Copper Coils

 

Copper is considered to be the most highly-rated thermal and electrical conductor compared to other metals. Thus, using copper coils are the central source of energy for larger machine infrastructures and in product designs. These coils are extremely efficient and reliable. The outstanding benefits that custom copper coils provide includes the following:

• Lightweight
• Strong
• High thermal conductivity
• Long-lasting
• Requires little to no maintenance
• Anti-microbial
• Corrosion resistant
• Easily formed into a shape
• Reusable and recyclable

 

Characteristics of Copper Tube

 

Size and Form

Copper Coils and Pipes come in only round shapes. However, the Copper Tube can be round, square, rectangle, and oval according to requirements. Larger applications use copper piping whereas smaller applications use copper tubing.

Retractable Abilities

A major difference between tube and pipe is the retracting or telescopic ability of the tube. A copper tube can be telescoped unlike a pipe to expand into another tube.

Rigidity

A copper pipe cannot be shaped or folded easily without using different tools. You have to use different fittings to make them stay put in certain locations. However, a copper coil or tube can easily be bent with a little effort due to its ductile nature.

Galvanization

Both copper coils and tubes can be galvanized. Although the copper tubes can be hot rolled as well as cold rolled, the copper pipe can only be cold rolled.

Corrosion Resistance

As the Pipe and Tube both are made of copper which is commendable due to its corrosion-resistance qualities, it makes the piping and tubing safe for many applications such as HVAC systems and plumbing.

Heat Conductivity

Copper is a very effective heat-conducting metal which makes copper tubes and pipes excellent conductors of heat during the heat transfer applications.

 

Key Benefits For Using Copper Tubing Coil For Mechanical Systems

 

Versatility

Copper is easy to work and has excellent thermal conductivity, corrosion resistance and durability. It is available in two basic types of tube-plumbing tube and air conditioning/refrigeration (ACR) tube, and in both drawn (hard) and annealed (soft) tempers. Copper tubing is also available in a wide range of diameters (from 1/8 inch to 12 inches) and wall thicknesses. Fittings to suit every design application are readily obtained.

Variety of Applications

In mechanical systems of all kinds, copper does more than ever before. Today copper tube has proven superior for:

Underground water and gas services

Water distribution systems

Chilled water mains

Drainage and vent systems

Heating systems (including solar)

Fuel-oil systems

Oxygen systems

Non-flammable medical-gas systems

Moreover, copper is durable enough to embed in concrete without worry.

Wide Range of Sizes

Large diameter or small, there is a copper tube to fit every specification. Forced-circulation hot water heating systems use small and economical tube sizes with soldered joints and require less space for installation.

Problem-Free Performance

It is good engineering practice to use one material for all components throughout a mechanical system. The more copper used in an installation, the more you can count on dependable performance. Copper is known for its reliability. It has been used for plumbing and mechanical systems since metals were first employed in these applications. And its popularity in heating systems is a further indication of copper's superiority to alternative materials.

Long Lasting and Maintenance Free

Its long-lasting and maintenance-free characteristics make copper the leading choice for plumbing, heating, cooling and other mechanical systems. Copper never requires painting for protection from corrosion. In addition, a thin film forms inside the tube, providing natural protection from corrosion. Copper's trouble-free service means satisfied customers. And its universal acceptability assures compliance with major building codes. Copper is safe, too. It will not burn or support combustion. So it will not carry fire through floors, walls and ceilings, and it will not decompose into toxic gases.

Corrosion Resistance

Copper's excellent corrosion resistance is an important reason for its choice in so many applications. Solar energy systems, for example, benefit from copper's resistance to both atmospheric and aqueous corrosion. For water distribution and fire sprinkler systems, copper tube's internal corrosion resistance results in superior flow capacity. When calculating flow capacities, other plumbing materials require additional allowances for corrosion, scaling, out-of-roundness and smaller internal diameter when compared size-to-size with copper. Copper tube bores remain smooth, and internal diameters stay constant. Largely because of this, a copper fire sprinkler system can use smaller diameters to provide the same sprinkler coverage as a steel system-with significant savings in installed costs.

High Thermal Conductivity

Copper conducts heat up to eight times better than other metals. Comparing copper, aluminum and steel, copper is by far the best conductor of heat. In solar energy systems, copper's superior thermal conductivity means that thinner copper sheet can collect the same heat as a much thicker-gauge sheet of aluminum or steel. And it means that copper collector tubes can be more widely spaced.

Easy to Join and Install

Tubes and fitting are easily joined metallurgically by soldering or brazing. And copper is so ductile that it can be formed-frequently right on the job site-to fit most design configurations. Because of copper's formability, it is often possible to eliminate elbows and joints. Since copper is rigid as well as readily formable, it adds to total system integrity even when subjected to adverse conditions.

Types of Copper Tubing

 

Soft annealed copper

These are always sold in rolls and this bends the easiest "straight from the coil". This is the copper to use when making spiraled condensers.

Cold drawn copper

These are always sold in straight lengths and is much harder than annealed copper because it work-hardened during the drawing process. It needs to be annealed (see later how to anneal copper) before bending otherwise it bends very difficult and tends to collapse or crack easily. Not recommended for spiraled condensers in distilling equipment.

 

Many Uses of Copper Coil

 

Copper is a great choice of metal to use for many different projects especially when electricity is involved. Copper can conduct electricity better among any other metals out there making it predominantly found in the engineering, heating, refrigeration, cooling electrical and heat exchanging application industries. Different shapes and sizes of copper can be cut out of large sheets of it and can be formed into rods, plates, pipes, sheets, coils and many more based on use and application.

Copper coil is copper that is made up to include multiple turns. When all rolled up and sitting down, it can look similar to a toy slinky or even a hose depending on the diameter of the coil. Because it is made out of copper is serves as an electromagnetic coil that will act as a conductor. Copper coils can be found in the back of a refrigerator, in a space heater or any kind of heating system. They are also used and play a role in running big industrial machines and equipment.

Craft fairs and art shows are pretty popular for many people to attend these days. Copper coil is used to create many art pieces and it gives them a unique look. Whether a piece is made completely out of copper coil, or just a few elements are highlighted by using it, it ads flare. Many women who make homemade jewelry are using copper as well as a part of their designs. Copper can get quite shinny and flashy just as other jewelry can look. Jewelry made out of this is not as common as your basic silver and gold pieces. Its color is unique and different from other pieces and it can be bent and formed into whatever creation one wants.

 

How To Install Copper Coil?

 

Capillary fittings are fittings that have a socket-type end which could help to close the tolerance gap between copper coil and the connecting fittings. When both copper coil and capillary fittings are cleaned and fluxed, they can form a small even gap between them upon assembly. As a result, when the solder is heated until it melts, the forces of adhesion and cohesion will cause the melted solder to flow into the capillary gap and a strong and watertight joint can be formed. The method of making capillary joints involves the following steps:

Step 1

Measure and cut the copper coil to the length needed and make sure it is cut neither too short nor too long so that a proper joint can be achieved.

Step 2

The coil and capillary fittings need to be cleaned by using sand paper or steel wool. Once cleaned, a sufficient flux will be applied resulting in a thin coat on the mating surfaces. This is to prevent dust and dirt from contaminating the capillary gap. Once the copper coil and capillary fittings are fluxed, the joint is ready for heating.

Step 3

Heat the joint and the solder should melt when it is brought into contact with the coil. Continue the heating process if the solder does not melt. The capillary gap should be filled with sufficient solder all around the coil.

Step 4

Be aware that any excessive solder will lead to a bead formed at the bottom of the joint or there is a chance that it will run inside the coil along the system. There is a small hint on the length of solder needed for soldering on small tube diameters. A length of solder which approximately equals to the diameter of the tube should be enough to fill the joint.

Step 5

After the soldering is done and the joint has been made, allow them to be cooled down so the solder can solidify without any disturbance.

Step 6

Lastly, wipe the outer surface of the tube with a cloth to remove any excess of flux on it.
