What is standard copper tube?
Standard Tubes: Types of Copper Tube. Long lasting copper tube is a favorite choice for plumbing, heating, cooling and other systems. In the United States, it is manufactured to meet the requirements of specifications established by ASTM International. All tube supplied to these ASTM standards is a minimum of 99.9 percent pure copper.
What is the difference between a K and L gas tube?
Each type represents a series of sizes with different wall thicknesses. Type K tube has thicker walls than Type L tube, and Type L walls are thicker than Type M, for any given diameter. All inside diameters depend on tube size and wall thickness.
What is the minimum copper content for ASTM?
All tube supplied to these ASTM standards is a minimum of 99.9 percent pure copper. The copper customarily used for tube supplied to these specifications is deoxidized with phosphorus and referred to as UNS C12200 or DHP 1 Copper. Other coppers may also be used.

What is a copper water tube?
Copper water tube is a seamless, almost pure copper material manufactured to the requirements of ASTM B 88 - Standard Specification for Seamless Copper Water Tube, of three basic wall thickness dimensions designated as types K, L, and M. Type K is the thickest and type M is the thinnest with type L being of intermediate thickness. All three types of tube are manufactured from copper alloy C12200 having a chemical composition of a minimum of 99.9% Copper (Cu) and Silver (Ag) combined and a maximum allowable range of Phosphorous (P) of 0.015 % - 0.040 %.
What is the copper content of a brass tube?
the copper (Cu) content of these alloys ranges from 62.0% to 96.0% depending on the alloy chosen.
What is a DWV tube?
Seamless copper tube used for sanitary drainage, waste and vent systems in plumbing applications is often referred to as "DWV" tube and is manufactured to the requirements of ASTM B 306 - Standard Specification for Copper Drainage Tube (DWV). DWV tube is manufactured from alloy C12200 that is 99.9% copper (Cu) and has a phosphorous (P) content of between 0.015% to 0.040%. DWV copper tube is furnished in H58 drawn (hard) temper only, in sizes 1¼" through 8". The standard length for DWV tube is 20 foot, however other lengths may be provided through prior agreement between the purchaser and the manufacturer. DWV copper tube shall be identified in two manners. The first is by an incised mark, at intervals not greater than 1½ feet, containing the manufacturers name or trademark and "DWV". The second is by a continuous yellow stripe containing the manufacturer's name or trademark, the nation of origin and "DWV" to be repeated at intervals not greater than 3 feet. Soldering of drainage pattern fittings meeting the ASME/ANSI B16.23 or B16.29 standards is the usual manner for joining DWV tube.
What are B 280 tubes?
B 280 tube is produced in straight lengths or coils in tempers H58 or O60 respectively, although annealed straight lengths may be special ordered. Straight lengths are provided in sizes from 3/8" O.D. through 4 1/8" O.D. while annealed coils are supplied in sizes ranging from 1/8" O.D. through 1 5/8" O.D. ACR tube is required to be identified in the following fashion: Coils: The name or trademark of the manufacturer and ACR shall be permanently incised on each tube ¼" or larger at Intervals not greater than 1½ ft. Hard Straight Lengths: The name or trademark of the manufacturer and a mark indicating either L or ACR shall be incised at intervals not greater than 1½ ft. along the length of the tube. Hard straight lengths shall further be marked with a blue stripe containing the manufacturer's name or trademark, the nation of origin, outside diameter and ACR repeating at intervals not greater than 3 ft.
What is a bright annealed copper tube?
Bright annealed copper tube is an almost pure copper tube manufactured to the requirements of ASTM B 68 - Standard Specification for Seamless Copper Tube, Bright Annealed. It may be manufactured from any one of the following alloys: C10200, C10300, C10800, C12000, or C12200 unless specified otherwise on the original contract or purchase order. ASTM B68 tube is suitable for use in refrigeration, fuel oil, gasoline, or oil lines where the interior surface of the tube is essentially free of any scale or dirt and is specifically specified as ASTM B68.
What type of alloy is used for medical gas tubes?
(Both of these types are defined and described in ASTM B88.) Alloy C12200 is the only alloy permitted for use for medical gas tube and is a minimum 99.9% pure copper (Cu) and silver (Ag) combined with no greater than 0.040% phosphorous (P).
What is copper pipe?
Copper pipe is almost pure copper manufactured to the requirements of ASTM B 42 - Standard Specification for Seamless Copper Pipe, Standard Sizes. It may be manufactured from any of five (5) copper alloys (C10200, C10300, C10800, C12000, C12200) that all conform to the chemical composition requirements of alloys containing a minimum of 99.9% Copper (Cu) and a maximum of 0.04% Phosphorous (P). Available sizes are 1/8" to 12" diameters in regular wall thickness and 1/8" to 10" in extra strong wall thickness. The standard length for copper pipe is 12 feet. Copper pipe is suitable for plumbing, boiler feed lines, refrigeration and for similar purposes.
What is a K pipe?
Distinguished by green markings, Type K pipe is available in both rigid form and in flexible rolls. 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.
What is copper pipe used for?
Photo: depositphotos.com. Copper pipes have been used as water supply lines in homes for decades, and you’ve probably seen them under your cabinets or overhead in your basement. Most people know that pipes come in different diameters, but what you may not realize is that some types of copper pipes are thicker than others, too.
What is type L water pipe?
Marked with blue and equipped for interior water supply systems, hot water heating systems, and fire protection such as sprinkler systems, Type L is the most commonly used of the copper pipe types. 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.
What type of copper pipe is used for underground water lines?
2. Type L Copper Pipe. While not quite as thick as Type K, with a wall thickness of .045 inches for a ¾-inch diameter pipe, it is still quite durable and can be used in many more ways. Type L is beefy enough to be used in underground applications but is often used to replace or repair water lines.
What type of copper pipe is best for a home?
1. Type K Copper Pipe. Of all copper pipe types, Type K has the thickest walls and is the most durable.
What is the thickest type of copper pipe?
Of all copper pipe types, Type K has the thickest walls and is the most durable. Pipe wall thickness varies according to the pipe diameter. ½-inch Type K pipe has a wall thickness of .049 inches, while ¾-inch has a thickness of .065 inches. Its thickness also makes Type K the heaviest and most expensive type of copper pipe. 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. Type K’s thickness lends itself to use in commercial plumbing, HVAC, and sprinkler systems but most commonly found in underground water main installations. 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.
What is the difference between Type M and Type M copper pipe?
Best of all, it costs less than the other copper pipe types! Advertisement. Type M has red markings and comes in flexible rolls and rigid tubing. While it isn’t often used in outdoor underground applications, Type M copper pipe is a perfect fit and plenty durable if you are looking to run a water system in your home.
