What is copper Tube?

Copper is a part of many applications over the past and continues to be a valuable one, even today. Primarily it is involved in systems that convey water across. From residential complexes to offices and industrial areas, this metal has many users. The tubing material is a part of HVAC systems. HVAC or Heating, ventilation, and air conditioning is a system that offers acceptable quality indoor air as well as thermal comfort. The tubing is available in two tempers, which are soft and hard. Drawing tubes makes them hard and rigid. To soften the material is tempered by annealing. The production of a softened pipe is much more expensive than a hard, non-annealed variety. Softer copper tubes are a popular choice for refrigerant lines. Their applications include both split-system air conditioners as well as heat pumps. Contrary to the former temper type, hardened or rigid temper tubes are less expensive and are popular as waterlines. Methods such as roll grooved, solder or sweat, compression, or crimped/pressed could be apt in forming a connection between the tube and fitting.

Since the metal is hard and does not bend, the use of fittings like an elbow is routine around obstacles or corners. Methods such as solder or sweat, roll grooved, compression, or crimped/pressed are used to forge a connection between a tube and a fitting.

Tubes supplied according to ASTM specification are 99% copper. And these tubes are available in six grades. They consist of type K, type L, type M, DWV, ACR as well as Medical gas. The standard ASTM size, designate the fore-mentioned grades. Every grade signifies a set of different sizes with varying wall thicknesses. For instance, the walls of type K are thicker in comparison to type L, while type M is thicker than that of type L for any produced diameter.

Difference between Seamless & welded copper tubing.

The production of a welded tubing is from either a metal sheet or a strip. The welded variety is free from filler metal and has a seam on the longitudinal section. The formation of a tube via extrusion is known as a seamless. Unlike its welded counterpart, the molten metal passes through a billet. Hence, there is no visible seam. However, with an increase in the surface treatment or polishing processes, the weld seam could be minimized to a large degree. Some types of surface treatment work towards reducing the seam to such an extent - that it is not visible to the naked eye.

Another point of differentiation between the two types is the cost factor. Typically, a welded tubing is cheaper to produce in comparison to a seamless kind. The standard specification for a welded cu tubing is ASTM B 447, whereas the specification for a seamless one includes - ASTM B 88 or ASTM B 75 or ASTM B 68, depending on the finishing performed on the tube.

For instance, bright annealed tubes adhere to specification ASTM B 68. Whereas, specification ASTM B 75 covers regular seamless tubes, and lastly, water tubes of this variety are covered by specification ASTM B 88.

A shortcoming associated with a seamless tube is that the production with regards to length is limited. Its counterpart, however, does not have length restrictions. Though using a weld version is discouraged in environments where they are likely to become prone to hydrogen embrittlement. Hydrogen embrittlement causes stress, which in turn leads to the tube cracking.

One of the specifications considered in the manufacture of Copper Tube is the ASTM B75. Apart from conforming to the chemical parameters, the specified ASTM B75 Copper Welded Tubing also need to conform to the mechanical parameters as well. In terms of the chemistry of these copper tubes, the content of elements copper, arsenic and phosphorous must be met with the chemical requirements specified in the ASTM B75. On the other hand, the Copper ERW Tubes conform to the mechanical property with the requirements such as tensile strength, yield strength, Rockwell hardness, as well as straightening being followed through. Moreover, there are certain tests which not only determine the chemistry and the mechanical properties of the Copper Round Tubing, but these tests are also devised to check if the other requirements such as electrical mass resistivity, grain size and dimensions meet the ASTM B75 specification.

While the specification takes into consideration Copper Seamless Tubes with regards to the construction, these tubes can be formed in various shapes such as round, square and rectangular.  Devised in a manner that could be used to change a high pressure liquid refrigerant into a low pressure spray of refrigerant, a Copper Capillary Tube in simple words is a really thin tube. The aggregate of pressure drop for a capillary tube tends to be dependent on both the tube’s length as well as its inside diameter.

Copper Tube Welding

Copper Tube are used where high purity, resistence to bio fouling and bacteria and extreme corrosion resistance are required. They are good strength and formability. It is not difficult to weld if proper procedures and environmental precautions are used.

The two main grades of copper nickel alloys are 90/10 copper to nickel and 70/30 (70% copper and 30% nickel). These are also called solution solution alloys. This means any amount of copper is soluble in nickel and any amount of nickel is soluble in copper.

When working with copper nickel alloys no pereheat and post-weld heat treatments are needed. Neither the weld or heat-affected zone are hardened by the heat of welding.
