Copper Tube Cutting and Bending Quiz

What is the objective of Section Two in the learning material?

• To describe the different methods for cutting and bending steel pipe.

• To describe the different methods for cutting and bending copper tube.

• To explain the safety measures for cutting and bending copper tube.

• To list the tools required for cutting and bending plastic pipe.

What is the correct use of the 'end-to-center' measurement method?

• For tube that has a fitting joined on one end only; tube length is equal to the measurement plus the distance from the face to the back of one sweated-on fitting.

• For tube that has a fitting joined on one end only; tube length is equal to the dimension of the fitting minus the end-to-center dimension of the fitting.

• For tube that has fittings joined on both ends; tube length is equal to the measurement from the center of one of the fittings to the face of the opposite fitting, plus twice the insertion length.

• For tube that has fittings joined on both ends; tube length is equal to the measurement from the center of one of the fittings to the face of the opposite fitting.

What is 'capillary action' in the context of soldering copper tube?

• The process of bending the copper tube.

• The process of cutting the copper tube.

• The process of joining two copper tubes.

• The process during soldering in which the molten solder flows into the narrow gap between the pipe and the joint.

What is the preferred tool for cutting copper tubing because it leaves no metal particles?

• Hacksaw

• Midget cutter

• Tube cutter

• Deburring tool

What is the purpose of reaming the inside diameter of the tube after cutting?

• To sharpen the cutting wheel

• To remove burrs for a smooth inner surface

• To tighten the tube cutter on the tube

• To clean the outside of the tube

Which tool is used to ensure a round tube end that has become deformed?

• Hacksaw

• Sizing tool

• Tube cutter

• Deburring blade

What is the minimum number of teeth per inch recommended for a saw blade when cutting large size drawn tubing?

• 12 teeth per inch

• 24 teeth per inch

• 32 teeth per inch

• 40 teeth per inch

Why is bending preferred over cutting for certain kinds of soft copper tubing?

• It is easier to perform

• It reduces the number of joints and fittings, thus reducing leaks

• It is a faster process

• It creates a smoother surface

What should be used to clean the inside of the tubing after cutting and filing?

• A deburring blade

• A sizing tool

• A Fitting Brush

• A tube cutter

What is the purpose of using tube-bending springs on the outside of the tube?

• To prevent the tube from flattening

• To increase the bending angle

• To measure the tube length

• To clean the tube surface
