What is the material used for the inner pipe of a Type B vent pipe?

• A. Steel
• B. Plastic
• C. Aluminum
• D. Copper

Answer: (C)

The inner pipe of a Type B vent pipe is made of aluminum because of its excellent properties for venting. Aluminum is lightweight, resistant to corrosion, and has good thermal conductivity, which allows for effective venting of products of combustion from gas appliances. Type B vent pipes are specifically designed for gas appliances that produce flue gases at higher temperatures and need to exhaust safely, and aluminum fulfills these requirements while ensuring safety and durability. Other materials like steel, plastic, and copper do not provide the same balance of properties required for a Type B vent pipe, particularly in terms of weight, thermal management, and corrosion resistance.
