Copper pipes remain the preferred choice for many. If working with copper pipes, there are a number of occasions when they will need to be connected. There are two commonly used methods for this: soldering and compression fittings.
Soldering
A traditional and still relatively popular method, soldering involves using a gluey substance known as ‘solder’ to bond the pipes together.
Soldering – pros
Soldered joints are strong and permanent and can last decades with minimal maintenance. Soldered joints are seamless and highly resistant to leaks. Soldered joints can also withstand high temperatures, and the materials are relatively cheap.
Soldering – cons
Soldering is rarely labour intensive, which means costs can be higher. Soldering is quite time-consuming. Soldering requires significant expertise and knowledge of safety due to handling open flames. As soldering creates permanent connections, removing the joint can be tricky if required.
Experts in copper pipe fittings
If you feel that compression pipe fittings are the best choice for you, a number of companies specialise in copper pipe fittings.
Compression fittings
Compression fittings are special connectors for joining copper pipes. They consist of a compression nut, compression ring, and a fitting body.
Compression fittings – pros
Compression fittings are very simple and quick to use, and they do not need flames. Compression fittings can be disassembled and reused multiple times without damage. Compression fittings are reasonably durable and reliable, with proper tightening ensuring a secure connection. Using compression fittings is much less labour-intensive than using soldering, so this can help keep costs down.
Compression fittings – cons
Joints made using compression fittings may loosen over time due to vibrations or pressure changes, and improper installation may cause leaks. Compression fittings can also be less able to deal with extremely high temperatures.
Which is best?
To decide which joining method you should use, you must consider the specific application, maintenance needs, budget, and skill level needed. Another key consideration is whether using a flame-based method is safe.
