Instructions: Choose the best answer for each question.
1. What is the primary difference between wrought metal and cast metal? a) Wrought metal is shaped by pouring molten metal into a mold.
Incorrect. This describes casting, not wrought metal.
Correct! Wrought metal is shaped by mechanical processes like rolling, extruding, and forging.
Incorrect. Wrought metal is often stronger and more durable than cast metal.
Incorrect. The cost of wrought and cast metal varies depending on the specific alloy and production method.
2. Which of the following is NOT a common method used to shape wrought metal? a) Rolling
Incorrect. Rolling is a common method for shaping wrought metal.
Incorrect. Extrusion is a common method for shaping wrought metal.
Correct! Casting is used to shape cast metal, not wrought metal.
Incorrect. Forging is a common method for shaping wrought metal.
3. Which of the following is a key advantage of using wrought metal in Oil & Gas applications? a) Lower production costs
Incorrect. Production costs can vary depending on the specific alloy and process.
Correct! Wrought metal is known for its superior strength and durability.
Incorrect. Wrought metal alloys are often designed for corrosion resistance.
Incorrect. Weldability depends on the specific metal alloy, not just if it's wrought or cast.

Incorrect. Plastic pipes are not made from wrought metal.
Correct! Drilling bits, collars, and other equipment often utilize wrought steel alloys.
Incorrect. Cement is not a wrought metal application.
Incorrect. Insulation materials are not typically made from wrought metal.
5. What is the primary reason for using wrought metal in valves and fittings for Oil & Gas operations? a) Lightweight construction
Incorrect. While weight is a factor, it's not the primary reason for choosing wrought metal in valves and fittings.
Incorrect. Corrosion resistance is important, but not the main reason for choosing wrought metal in valves and fittings.
Correct! Wrought metal allows for the creation of components with precise dimensions, ensuring a proper fit and function in valves and fittings.
Incorrect. While cost is a factor, it's not the primary reason for choosing wrought metal in valves and fittings.
Task: You are working on a project to design a new type of valve for high-pressure gas pipelines. You need to choose the best material for this valve. Considering the advantages of wrought metal, explain why it would be a suitable choice over cast metal for this application.
Solution:
Wrought metal is the ideal choice for high-pressure gas pipeline valves due to its superior strength, durability, and precise dimensional control. Here's why:
Therefore, choosing wrought metal for this valve would ensure a reliable, durable, and safe solution for high-pressure gas pipeline applications.
