Copper Pipes
|
These copper pipes do follow the American Society for Testing and Materials Standards. This means that it is internationally viable as well as performing for its duties. There are two types of copper tubes that are available, and those are the JIS H3300 C1220T tubes, and the ASTM B88 tubes.
The copper pipes are used to transfer liquids. It is very good and used worldwide in piping due to these three characteristics; it is light, it is strong and it is corrosion resistant. It serves in all kinds of buildings, in small homes until the largest industrial buildings. |

What are Copper Pipes Specifications

1. What are copper pipes?
Some of the most common ways to use a copper pipe nowadays is for construction industry for water supply lines and refrigerant line in heating, ventilation, and air-conditioning (HVAC) systems. Whilst this can mean AC, many don't realize that this copper tube system is what keeps our refrigerators and our freezers alive. |

While the majority of the copper tube applications lie in the residential sector, where they are used to convey potable water in homes and offices, refrigerator industries, firefighting systems, and medical and residential gas suppliers are also catching up.
2. What percentage of copper is in copper pipe?
Copper pipes contain more than 99.9% of pure Copper. The process of extracting pure copper is considered to be more critical in its production chain compared to fabrication and installation. The copper pipes are made in order to fulfil JIS standards, which stands for the Japanese Industrial Standard as well as the ASTM standard.
These two types of pipes are created to fulfil different roles, and hence need to follow different standards in order to meet the required specification that is necessary for its purpose. The JIS H3300 C1220T copper pipe is more suitable for water works. This ranges from showering systems to overall water systems in a building or in a home. At the other end, the ASTM B88 copper tube is more suitable for heat sensitive purposes, such as air conditioning and refrigeration.

3. How do you measure copper pipe size?
The copper pipes outer diameter (OD) can be measured in inches (“), nominal Bore (NB), and metric size. Nominal bore and outer diameter size is corresponded to each other’s. The outer diameter is always 1/8 inch bigger than the nominal size. For example, a 2” nominal bore copper pipe is equal to 2 1/8" outer diameter. It is applicable to all three common types of pipe. The size of diameter that is available ranges from 6 mm to 54 mm, while nominal bore size available size from 1/8” to 4”.

4. What is the wall thickness of Type K, L, M copper pipe?
Three different types of ASTM B88 copper pipes used in system installation are type L, M and K. They are considered some of the most common types of pipes, with its actual purpose being similar, but their specifications a tiny bit different. The key difference between these three types of copper pipes is that Type K pipes have thicker walls compared to Type L, and Type L walls thickness is thicker than Type M. Therefore, the copper pipe wall thickness determines different working pressure and application for each type of pipe.

6. How do you install copper pipes?
Copper pipes are very flexible during installation due to its formability. A quick change of bends as well as length can be easily done on site, given the right tools and methods. The tube itself will not grow weaker, or even break even because of bending.
Testing report has shown that a bent copper pipe bursting strength can be greater than it was before bending. This means that the copper tube sometimes even grows stronger as it gets bended. Copper tubes are very easily installed, with joints being used on a regular basis, and easy welding or using flanges being done in order to put two tubes together.
