What is copper tubing?

Copper tube, also known as copper tube, is a seamlessly pressed and drawn non-ferrous metal tube. Copper pipes have the characteristics of good electrical and thermal conductivity. They are the main material for conductive accessories and heat dissipation accessories of electronic products. They have become the first choice for installing water pipes, heating and refrigeration pipes in all modern residential buildings. Copper pipes are corrosion-resistant, not easily oxidized, not prone to chemical reactions with certain liquid substances, and are easy to bend into concave shapes.

Types of Copper Tubes

Soft Copper Tubing

Soft copper tubing is easy to bend around obstacles in the piping. Although work-hardening during drawing hardens the copper tube, it softens again after careful annealing; therefore, soft copper tubing is more expensive to produce than unannealed hard copper tubing. Soft copper tubing can be connected by any of the three methods used for hard copper tubing, and is the only type of copper tubing suitable for flared connections. Soft copper tubing is the most commonly used tubing for refrigerant lines in split air conditioners and heat pumps.

Rigid copper

Hard copper is a popular choice for water pipes. Rigid or "hard" copper tubing is often called "ducting." Copper "pipe" refers to the nominal size or inside diameter of the pipe. It joins using solder/solder, roll groove, compression or crimp/pressed connections. Hard copper becomes hard due to work hardening during the drawing process and cannot be bent, and elbow fittings must be used to get around corners or obstacles. If heated and cooled during the annealing process, the rigid copper will soften and can be bent/shaped without cracking.

Advantages of Copper Tubes

Good heat transfer

Copper tubes allow heat to be transferred from one medium to another very quickly, making them very useful in applications that require heat transfer, such as heating, cooling, and temperature control.

Good strength and moldability

Copper pipes have good strength and ductility and can be made into different shapes such as round, square, hexagonal, etc., so copper pipes are suitable for manufacturing various types of products.

Good corrosion resistance

Copper tubes have good corrosion resistance and can be used in many special environments.

Good reproducibility and renewability

Copper pipes can be recycled and remanufactured into other copper pipes, with good repeatability and reproducibility.

Copper Tube Applications

Construction

Copper pipes are most widely used in the construction field. Copper pipes can be used in water supply lines, HVAC systems, natural gas lines, and more. Copper pipes have good corrosion resistance and antibacterial properties, which can ensure the health and safety of the water supply. They can also effectively conduct heat and improve the efficiency of the HVAC system.

Electrical and Electronic Fields

Copper is an excellent conductive material, so copper tubes are widely used in electrical and electronic fields. It can be used to manufacture electrical equipment such as wires, cables, transformers, and inductors. The electrical conductivity of copper tubes is stable and reliable, ensuring the efficiency of current transmission. It can also effectively dissipate heat and ensure the normal operation of electrical equipment.

Industrial field

Copper pipes also have important applications in industry. It can be used to manufacture heat exchangers, condensers, evaporators and other thermal equipment. Copper tubes have good thermal conductivity and can quickly conduct heat and improve the efficiency of thermal equipment. At the same time, the corrosion resistance of copper pipes can also ensure the service life of the equipment.

Automobile Manufacturing

Copper tubes are also widely used in automobile manufacturing. It can be used to manufacture automobile radiators, air conditioning systems, braking systems, etc. Copper tubes have good thermal conductivity and corrosion resistance, which can effectively dissipate heat and improve the performance and safety of cars.

Copper Tube Size

Common copper pipe wall thicknesses are "Type K", "Type L", "Type M" and "Type DWV":
Type K copper pipe is the thickest walled of the three pressure rated copper pipe types and is typically used deep underground, such as under sidewalks and streets, and is coated with an appropriate corrosion resistant coating or continuous polyethylene casing as required by plumbing codes.
Type L pipe has a thinner wall and is used for residential and commercial water supply and pressure applications.
Model M has a thinner wall and is used in residential and commercial low-pressure heating applications.
The DWV model has the thinnest wall cross-section and is typically used only in non-pressurized applications such as drain, sewer, and vent (DWV) piping.

Copper tube production process

Smelting Raw Copper

The first step in the manufacturing process of copper pipes involves smelting raw copper. Raw copper is placed inside a large furnace where it’s heated to temperatures in excess of 2,400 degrees Fahrenheit. As the raw copper heats up, it turns from a solid state to a liquid state.

Forming the Pipes

The next step in the manufacturing process of copper pipes is formation. After the raw copper has been smelted, as well as purified through the removal of impurities, it’s transferred into a pipe-shaped casting. The casting is essentially a shell in the shape of a pipe. A worker pours the molten copper into the casting, after which he or she waits for it to cool.

Finishing the Pipes

The final step in the manufacturing process of copper pipes involves resizing and cleaning. The newly created copper pipe is fed through a series of dies where it’s cut into one or more specific sizes. Next, the copper pipe is cleaned using water and/or solvents.

FAQ

Q: What is the most commonly used copper tube?

A: Type L is considered the most common type of copper piping, as it can be used in many more applications than Type K. Flexible Type L copper can be used to repair or replace old water lines, although rigid tubing is more durable. Type L also can be used outside the home where it will be directly exposed.

Q: What is the purpose of copper tubing?

A: Copper tubing is commonly found in use for heating systems and in hot and cold water transportation. Copper used to be really popular for hot and cold water supply. You can also find copper pipes as a refrigerant line in HVAC systems.

Q: Which types of fittings are commonly used with copper tubing?

A: While copper tube is usually joined by soldering or brazing, there are times when a mechanical joint may be required or preferred. Flared fittings are an alternative when the use of an open flame is either not desired or impractical.

Q: What tool is used to prepare copper tubing?

A: The most popular flaring tool for copper tubing is the bar-type tool. It has include multiple bits to accommodate different pipe or tube sizes. Tubing and piping flares are not interchangeable. Tubing flares have a 45-degree angle while piping flares have a 37-degree angle.

Q: What type of copper tubing is the thickest?

A: Type K copper pipe has the thickest wall of all the common types. It is used for water distribution, fire protection, oil, HVAC, and many other applications in the construction industry. Type K pipe is available in rigid and flexible forms.

Q: Why is copper tubing so expensive?

A: Copper is sort of the gold standard in pipes. Known for its durability, it can last aslong as 100 years. Copper pipes are naturally resistant to bacteria and are less likely tobreak down if exposed to UV rays. As a result, the cost of copper pipe per foot exceeds a lotof other piping options.

Q: What are the three techniques for joining copper tubing?

A: These joining methods include soldering, brazing and electric resistance. Soldered jointswith capillary fittings, are used in plumbing for water lines and for sanitary drainage.

Q: What are two methods for cutting copper tubing?

A: Most of the tools are power saws, but there are two notable manual tools. the hacksaw andthe auto cut tool. No matter which tool cuts through the copper pipe, remember to deburrand smooth the end of the cut pipe after cutting. Hacksaw: When using a hacksaw to cutcopper pipe, choose a 32TP|(teeth-per-inch)blade.

Q: How to measure copper tubing size?

A: Take a string or flexible tape and wrap it around the pipe. Make a mark and then measurehow long the string or tape is. Once you have the string's length you'll need to divide thatmeasurement by pi (pi= 3.1415) to find the pipe's diameter.

Q: How should copper tubing be stored safely?

A: Copper Pipe is generally stored on Cantilever Racking but can also be stored in VerticalRacks /A-Frame Racking or in a Pigeon Hole format dependent upon individual customerrequirements.
