Copper tubing is usually available in either soft or hard presentations. While the work hardening of the drawing process used to size the tubing makes the copper hard or rigid, it is carefully annealedto make it soft again; it is, therefore, more expensive to produce than non-annealed, rigid copper tubing. ASTM B280 is the Standard Specification for Seamless Copper Tube for Air Conditioning and Refrigeration Field Service and is measured and called by the Outside Diam Type K, L, and M. These tubes are alike except for differences in wall thickness, with Type K having the thickest walls and as a result the highest pressure-rating. It comes in both flexible rolls and rigid tubing, with the rigid tubing usually used for internal water piping and the flexible rolls used underground and outside the home. Here you can learn more about the products we offer, get insight into the technical aspects of copper and stay up to date with the latest news and trends within the copper industry. You’ll often find flexible rolls of Type K used for underground water mains because they are easier to run in a trench, require no fittings, and can be used with compression and flared fittings. In fact, its affordable price point makes it the most popular copper pipe for domestic water systems. Best of all, it costs less than the other copper pipe types! Soft (or ductile) copper tubing can be bent easily to travel around obstacles in the path of the tubing. It is also possible to expand the end of one tube so that it can be joined to another by soldering or brazing without a capillary fitting—a procedure that can be efficient and economical in many installations.

The coil is wound from copper tubing, is water-cooled, and has a lining of thermal insulation. Hydraulic, Pneumatic Design & Engineering | Fluid Power Engineering . "Temper" describes the strength and hardness of the tube. Type M has a wall thickness of .032 inches for a ¾-inch diameter pipe, making it a thinner wall than both Type K and Type L copper. The rigid form of Type K tubing is more likely to be used for commercial indoor applications and sprinkler systems. When making a selection below to narrow your results down, each selection made will reload the page to display the desired results. Welcome to the online home of Copper Tubing Africa, one of the leading copper tubing suppliers and manufacturers in South Africa. The soft copper is flexible and comes in rolls of 25 feet or 50 feet. Copper Tube. Of all copper pipe types, Type K has the thickest walls and is the most durable. Type L is thinner than type K and is used for water supply and pressure applications. Part #: KSOFTJ45. Sort By: Show: Quickview. Sign In to view purchased products. A thinner pipe can crimp or collapse underground, but Type K’s durability will allow it to last longer, meaning it doesn’t need to be dug up every few years. You may be surprised to find two types of copper pipe on the home center shelf, Type L and Type M. The difference is the wall thickness of the copper pipe sizes and therefore the pressure it can handle. All inside diameters depend on tube size and wall thickness. Soft (or ductile) copper tubing can be bent easily to travel around obstacles in the path of the tubing. You won’t find Type K copper pipes under your sink or connected to other plumbing fixtures; partly because they aren’t as easy to work with as other types of copper but mostly due to the prohibitive cost. If a home is known to have water issues like hard water, Type L copper is often the go-to choice because hard water will not wear through the thicker walls as easily as they will through Type M pipe. $18.69 . Type L also can be used outside the home where it will be directly exposed. "Temper" describes the strength and hardness of the tube. It is usually available as hard drawn straight sections and in rolls that have been annealed. It can be joined by any of the three methods used for rigid copper, and it is the only type of copper tubing suitable for flare connections. By Gary Sprague. Copper tubing size chart. Types of Copper Tube Table 1, page 20, identifies the six standard types of copper tube and their most common applications.2 The table also shows the ASTM Standard appropriate to the use of each type along with a listing of its commercially available lengths, sizes and tempers.

Type K Copper Tubing Coils are manufactured to spec ASTM B88 is the Standard Specification for Seamless Copper Tube, ANSI/NSF Standard 61 Drinking Water System Components. Tube in the soft temper can be joined by the same techniques and is also commonly joined by the use of flare-type and compression fittings. Editors’ Choice: Coils of Mueller Streamline Type K copper pipe (available at Lowe’s) are used in underground applications like water mains because of their ease of use and durability. x 45 ft.
