Steel Pipes by Types » Type K

Type K copper plumbing tube is a thin walled tube, which is the most common type of copper tube used in homes. These tubes are used mainly behind the walls to route water from the service line & water heater to the fixtures. Trunk lines are generally run in 3/4-in. type M copper with 1/2-in. Type M branching away to cater the individual fixtures.

Type K has the heaviest wall section of the four types of pressure rated tubing. It is generally used for high pressure applications and deep underground burial, such as - under sidewalks and streets, with a suitable corrosion protection coating or continuous polyethylene sleeve as needed by the code. Type K Tubes have found uses in all sorts of buildings, from the smallest to the largest, but especially in areas where the water is highly corrosive.

Type K tubes come in sizes ranging from 3/8" to 12" and have approximately the same thickness as that of iron pipe after it has been threaded. Type K copper tubing has a high bursting pressure, which is more than 5,000 lbs. per sq. inch.
