Tube and Tubing

What are the different fitting types and joining techniques used in tubing systems?

• Fitting types include flared, compression, and soldered fittings. Joining techniques include soldering, brazing, and mechanical joining.

• Fitting types include threaded, welded, and glued fittings. Joining techniques include nailing, stapling, and taping.

• Fitting types include magnetic, adhesive, and snap-on fittings. Joining techniques include painting, screwing, and clamping.

• Fitting types include bolted, riveted, and zip-tied fittings. Joining techniques include welding, gluing, and sewing.

What are some applications and manufacturer’s specifications related to joining methods in tubing systems?

• Applications include plumbing, HVAC, and industrial piping. Manufacturer’s specifications may include pressure ratings, temperature limits, and compatible materials.

• Applications are limited to electrical wiring only. Manufacturer’s specifications focus solely on color coding.

• Applications include only food processing. Manufacturer’s specifications are not required for tubing systems.

• Applications are exclusive to automotive painting. Manufacturer’s specifications only mention paint types.

What are some health and safety issues to consider when using joining methods for tubing systems?

• Health and safety issues include proper ventilation, use of personal protective equipment, and safe handling of tools and materials.

• Only the type of tubing material matters, not health and safety.

• Health and safety issues are not relevant when joining tubing systems.

• The only concern is the speed of joining, not safety.

What is the process for bending tubing in piping systems?

• The process involves measuring, marking, using a tube bender, and ensuring the bend radius meets specifications without kinking the tube.

• The process involves heating the tube until it melts and then shaping it by hand.

• The process involves cutting the tube into small pieces and gluing them at angles.

• The process involves hammering the tube flat and then folding it to the desired angle.

What are the fabrication processes for joining tubing systems?

• Fabrication processes include cutting, deburring, fitting assembly, and joining by soldering, brazing, or mechanical means.

• Fabrication processes include only painting and coating the tubing systems.

• Fabrication processes involve only the use of adhesives and tapes for joining.

• Fabrication processes are limited to welding and do not require any fitting assembly.

What steps are involved in assembling and pressure testing a project with flared, compression joints, and bending components?

• Steps include assembling the components, ensuring proper fit, performing the required bends, joining with flared or compression fittings, and conducting a pressure test to check for leaks.

• Only assemble the components and perform a visual inspection, no pressure test is required.

• Simply connect the joints without bending or pressure testing the components.

• Begin with pressure testing, then assemble the components without checking the fit or performing bends.

What is the term for the process: 'To heat and then cool, which softens and makes the copper more flexible.'?

• annealing

• tempering

• quenching

• galvanizing

What is the chemical symbol for copper?

• Co

• Cu

• Cp

• C

Copper is refined to what percentage of purity before it is made into seamless tube or pipe?

• 99.7%

• 98.5%

• 95.0%

• 90.2%

Which of the following is NOT an advantage of copper as a piping material?

• Malleability

• Ductility

• High resistance to corrosion

• Low coefficient of expansion
