All four classes of tubing can be used with the capillary solder system. The choice of tubing will. If tubes are to be laid underground then either. Class 2 or 3 should be used. Copper tubing in coils is usually selected for service in clay soils as. Class 0 is recommended for all above ground work as its use would provide the maximum cost saving. It is emphasized that Class 0 tubing is hard drawn and any change of direction should be made. Local annealing of Class 0 in order to produce a bend is not recommended. When compared with traditional systems, capillary systems can realize an installation time saving of up. SABS 4. 60 Class 1, 2 3 all have excellent bending qualities. There are various bending machines on the. Care should be taken when bending. Class 1 tube as it has a thin wall. The cheaper hand benders and springs do not perform. Half hard tubes bent by hand should have a radius of at least 6 times the outside diameter of the tube. Any deviation from the above figures could cause a restriction in the tube producing turbulent flow. It is most important to remember that SABS 4. Class 0 hard drawn tube should NOT be bent under. Class 0 tube is ideally suited for use with capillary fittings, however, compression. The use of a 9. 0 or 4. Copper tubing, due to the very smooth bore, maintains excellent flow characteristics as there is less. Because of copper tubes excellent internal corrosion resistance, tube bores remain smooth and. Coppers light weight facilitates shipment, fabrication and installation. When comparing steel pipe. This is significant in terms. Copper is compatible with all types of piping. It is accepted practice to join copper tubing to. Certain corrosion. When cutting copper tube with tubing cutters or a hacksaw, care should be taken to produce a square. This will remove the possibility of turbulent flow which. Technical Specifications Data Design. Composition, Related Specifications uses of Available Alloys. Copper. Alloy. Composition. Related.

The hydraulic character of a piping material, determined by the size and smoothness of its bore, enables. When comparing two smooth wall materials, such as copper and polypropylene, internal diameter. Comparison between 4. Copper tube Cu and Polypropylene tube PP showing area of bore. Nominal. Tube.

It is after all the bore of the pipe that is important when considering volumes, flow. Just how much the bore does vary is clearly shown in the tables above. When using plastic pipes, it would be a good rule of thumb to install one nominal size larger. Copper offers substantially greater bore areas than plastic for the same outer diameter of pipe. Example as per illustration above 2. Thermal Contraction Expansion SABS 4. Tubing. Thermal Contraction and Expansion.
