Copper pipes are popular in plumbing, cooling and heating systems. Here’s some basic information about this reliable, long-lasting material.
There are two types of copper pipes: soft and hard.
Soft copper pipes are annealed to make them soft and flexible, and they can be bent so that they can travel around potential obstacles. Hard copper pipes are not annealed. They’re rigid, so fittings like elbows are needed to change the direction of the fluid flow.
In the U.S., copper pipes often fall into one of four categories, based on their wall thicknesses.
Type K has the thickest walls and is often used underground, beneath streets and sidewalks.
Type L is one step down in thickness, and is often used for water supply in both residential and commercial buildings.
Type M is thinner still and also used for water supply.
Type DMW is the thinnest and primarily used in unpressurized applications, like waste lines or drains.
Copper pipe offers a number of advantages, including:
Copper pipes are most commonly used for water supply and as refrigerant line in HVAC systems, but they also see use in medical gas systems, solar heating systems and other industries.
Copper-nickel pipe–an alloy of copper, nickel and other strengthening elements–has interesting properties that make it suited for an even wider range of applications. It’s very resistant to corrosion in seawater, so you’ll often find copper-nickel pipes in condensers and exchangers in seawater systems, marine hardware, and sometimes in boat propellers, hulls and crankshafts.
