Type L and Type M copper pipes are two commonly used pipe sizes in plumbing systems. While both types of pipes serve similar functions, there are some differences between them that should be considered when choosing between them.
(Should I Use Type L Or Type M Copper Pipe)
Type L copper pipes are designed for use in situations where high-pressure or low-pressure water flow is required. They are larger than Type M pipes but smaller than Type X pipes. The material used to make Type L pipes is typically 28 gauge copper and they have a slightly wider diameter. Type L pipes are usually recommended for use in systems with a maximum water pressure of 4,000 psi (2,487 bar) and temperature range of -18°C to +25°C (-29°F to +68°F).
Type M copper pipes, on the other hand, are designed for use in situations where low-pressure or high-pressure water flow is required. They are smaller than Type L pipes but larger than Type X pipes. The material used to make Type M pipes is typically 30 gauge copper and they have a narrower diameter. Type M pipes are usually recommended for use in systems with a maximum water pressure of 1,600 psi (1,048 bar) and temperature range of -18°C to +50°C (-29°F to +86°F).
One key difference between Type L and Type M copper pipes is their diameter. Type L pipes have a wider diameter than Type M pipes, which means that they take up more space in the pipeline. This can be an advantage in certain situations where space is limited. For example, if you have a small bathroom or kitchen, you may want to choose a larger Type L pipe to save space.
Another important consideration is the flow rate that the system will need to handle. Type L pipes tend to have a higher flow rate than Type M pipes because they are larger. If your system requires a lot of water flow, it may be wise to choose Type L pipes instead of Type M pipes. However, if you only require low-flow water flow, Type M pipes may be a better choice.
Finally, it’s worth noting that Type L copper pipes tend to be less expensive than Type M copper pipes. While the cost of Type L pipes may be higher, they generally offer better durability and resistance to corrosion than Type M pipes.
(Should I Use Type L Or Type M Copper Pipe)
In conclusion, whether to use Type L or Type M copper pipe depends on the specific needs of your plumbing system. If you need a larger pipe that takes up more space, Type L pipes may be the better choice. On the other hand, if you only require low-flow water flow and want a more durable pipe, Type M pipes may be a better choice. It’s always a good idea to consult with a professional plumber to determine the best pipe size for your specific situation.
