Copper tubing can be joined in a variety of ways. Choosing the proper joining method depends on the specific application. Some common types of joints are threaded, mechanical, and soldered. These joint options offer reliable and affordable solutions to several plumbing and industrial applications.
Threaded joints are ideal for low-pressure flows. However, they may leak due to thermal expansion. For high-temperature areas, it is best to avoid these joinery methods. The best choice is to install a mechanical joint. This type of joint is simple and reliable but requires skilled workers to complete the job. Mechanical joint options include roll-groove joints and press-connect joints.
Mechanical joinery is less expensive than soldered joints, and it is also easy to disassemble and reassemble. Although it is less durable, it is suitable for moderate-temperature areas. Unlike soldered joints, mechanical joint options are generally smooth and do not alter the pipe’s characteristics. They can be used for various applications, including water supply lines.
Alternatively, copper tubing can be joined using brazing. Brazing involves heating the tube to a high temperature to anneal the metal. After a certain amount of time, the copper will soften. During the brazing process, a nitrogen purge is inserted into the tube to help prevent black oxidation.

Crimped or pressed connections can join rigid copper. Compression fittings are also commonly used to enter this type of pipe. Several types of compression fittings are available, and some are designed for use with low-pressure or high-pressure applications.
Brazed joints have lower pressure ratings than threaded or soldered joints. Butt weld joints, on the other hand, offer good strength. Additionally, butt weld joints can withstand high pressure.
To determine the outside diameter of the copper pipe, you need to subtract one inch from the nominal size of the pipe.
Copper tubes are available in various sizes and wall thicknesses. The thinnest, Type M, is perfect for indoor applications. On the other hand, Type K is the thickest of the three copper pipes and is typically used in water distribution systems. Also, Type L is the most common copper pipe used in HVAC, swimming pools, and other outdoor applications.
Besides being a reliable option, copper pipes can last for more than 50 years in ideal conditions.
There are several advantages to installing copper tubes in a residential or commercial application. From water distribution to HVAC, solar energy, refrigeration, and drainage, the durability and flexibility of copper tubing can be a great benefit.
