Phase 1 PP 6

What is the first step in method 1 for bending copper pipe 90 degrees?

• Place a short piece of tube in the former

• Measure the distance required and mark it on the tube

• Find the correct offset angle

• Anneal the tube between marks 2 and 3

How is the correct offset angle found for a copper pipe offset bend?

• Find the correct offset angle using a folding rule

• Remove the tube from the benders and mark the second bend

• Bend the tube to the angle set by the rule

• Measure the distance required and mark it on the tube

What is the recommended method for bending plastic pressure pipe?

• Using a hydraulic bender

• Using a set square

• Using a folding rule or template

• By hand, without the use of a bending machine

What is the purpose of annealing the copper pipe before bending with springs?

• To harden the copper

• To soften the copper

• To decrease the diameter of the pipe

• To increase the diameter of the pipe

What is the first step in bending low carbon steel 90 degrees?

• Pump the handle on the hydraulic bender

• Place the pipe in the hydraulic bender

• Measure the distance required and mark it on the tube

• Mark a line in the pipe at the required distance

What is the recommended minimum radius for plastic pressure pipes?

• Less than 1 inch

• 1 inch

• 3 inches

• 2 inches

What is the purpose of using cold forming bend fixtures for plastic pressure pipes?

• To harden the pipe

• To soften the pipe

• To hold the pipe in position

• To increase the diameter of the pipe

What is the second step in method 2 for bending copper pipe 90 degrees?

• Measure the distance required and mark it on the tube

• Place a short piece of tube in the former

• Place a set square against the two pieces of copper

• Bend the tube 90 degrees and check with a set square

What is the purpose of marking the second measurement 'Point B' in low carbon steel bending offset?

• To find the correct angle for the first bend

• To make the first bend to the required angle

• To measure the distance of the offset

• To line up the mark with the centre of the former

What is the purpose of repositioning the rule to give the correct angle for the second bend in copper pipe offset bend?

• To remove the tube from the benders and mark the second bend

• To reposition the tube back in the benders

• To bend the tube to the angle set by the rule

• To find the correct offset angle
