Instructions: Choose the best answer for each question.
1. What is the primary function of a landing nipple?
a) To connect pipes with different diameters. b) To provide a secure and leak-proof connection. c) To regulate the flow of fluids. d) To act as a pressure relief valve.
The correct answer is **b) To provide a secure and leak-proof connection.** Landing nipples are specifically designed to create a tight seal and prevent leaks.
2. Which of the following features is NOT typically found in a landing nipple?
a) A specific profile. b) A lock. c) A roughened bore. d) A polished bore.
The correct answer is **c) A roughened bore.** Landing nipples have a polished bore to minimize friction and ensure a tight seal.
3. In which of the following applications are landing nipples commonly used?
a) Domestic plumbing systems. b) Irrigation systems. c) High-pressure piping systems. d) All of the above.
The correct answer is **c) High-pressure piping systems.** Landing nipples are ideal for high-pressure applications due to their secure connections.
4. What is the main advantage of a landing nipple's polished bore?
a) It reduces the risk of corrosion. b) It enhances the aesthetic appearance. c) It allows for easier cleaning. d) It minimizes friction and ensures a tight seal.
The correct answer is **d) It minimizes friction and ensures a tight seal.** The polished bore creates a smooth surface that reduces friction and prevents leaks.
5. Which of the following statements about landing nipples is FALSE?
a) They can be used in instrumentation and control systems. b) They are highly durable and resistant to wear. c) They require frequent maintenance and repairs. d) They are commonly used in the aerospace and automotive industries.
The correct answer is **c) They require frequent maintenance and repairs.** The secure design and durable construction of landing nipples minimize the need for frequent maintenance.
Scenario: You are working on a high-pressure chemical processing system. The system requires a secure connection between a pipe and a pressure sensor. You need to choose the right type of fitting for this application.
Task:
**1. Why a landing nipple is ideal:** * A landing nipple provides a secure and leak-proof connection, essential for high-pressure chemical processing systems where leaks could be hazardous. * Its specific profile and lock mechanism ensure a tight fit and resist loosening under pressure. * The polished bore minimizes friction, optimizing the flow of chemicals and reducing the risk of clogging. **2. Key features for high-pressure, chemical processing:** * **Specific profile:** Ensures a precise fit between the nipple and the mating component. * **Lock mechanism:** Prevents accidental disconnection or loosening due to pressure fluctuations or vibrations. * **Polished bore:** Minimizes friction, reduces the risk of chemical build-up, and ensures a clean and hygienic connection. * **Durable material:** Resistant to chemical corrosion and high-pressure environments.
