Copper tube is the preferred material for water pipes, heat exchanger and refrigeration systems due to its high resistance to corrosion, high temperature and high pressure. China Metal Group is a professional manufacturer of copper tubes with the best quality, we combine advanced manufacturing methods and sophisticated quality control techniques to ensure that only consistently high standard copper tubes are supplied to our customers.

Type
Type K has the thickest wall section of the three types of pressure rated tubing and is commonly used for deep underground burial, such as under sidewalks and streets, with a suitable corrosion protection coating or continuous polyethylene sleeve as required by the plumbing code. This pipe designation is used in the Refrigeration Industry.
Type L has a thinner pipe wall section and is used in residential and commercial water supply and pressure applications.
Type M has an even thinner pipe wall section and is used in residential and commercial low-pressure heating applications.
Type DWV has the thinnest wall section and is generally only suitable for unpressurized applications, such as drain, waste, and vent (DWV) lines.
Type ACR(air conditioning and refrigeration field services) pipe and tubing, which is sized directly by its outside diameter (OD) and a typed letter indicating wall thickness.
