Instructions: Choose the best answer for each question.
1. What is the primary function of a companion flange?
a) To connect different pipe sizes. b) To act as a pressure relief valve. c) To mate with a nozzle, valve, or fitting. d) To control the flow of fluids.
c) To mate with a nozzle, valve, or fitting.
2. Why are companion flanges crucial for safety in oil & gas operations?
a) They prevent leaks and potential accidents. b) They allow for quick and easy repairs. c) They make it easier to transport oil & gas. d) They ensure consistent pressure throughout the system.
a) They prevent leaks and potential accidents.
3. Which type of companion flange is welded directly to the pipe?
a) Slip-On Flange b) Socket-Weld Flange c) Threaded Flange d) Welded Neck Flange
d) Welded Neck Flange
4. What is NOT a factor to consider when choosing a companion flange?
a) Pipe size and pressure rating b) Material compatibility c) Manufacturer's brand preference d) Operating conditions
c) Manufacturer's brand preference
5. Companion flanges promote standardization and integrity in oil & gas operations. What does this mean?
a) They are only made by one specific manufacturer. b) They ensure compatibility across different manufacturers and projects. c) They are only used for specific types of oil & gas. d) They are designed to work with any type of pipe.
b) They ensure compatibility across different manufacturers and projects.
Instructions: You are designing a new pipeline segment for an oil & gas facility. The segment will connect to an existing valve with a 6-inch diameter and a pressure rating of 1500 psi. You need to select the appropriate companion flange for this application.
Consider the following:
Task:
**1. Suitable Flange Type:** Welded Neck Flange **2. Reasoning:** * **Pipe Size and Pressure Rating:** The chosen flange must match the valve's 6-inch diameter and 1500 psi pressure rating. * **Material Compatibility:** Carbon steel is a suitable material for this application, as it is compatible with the existing valve and can withstand the operating temperature and potential for corrosion. * **Application and Operating Conditions:** Welded Neck Flanges provide a strong and permanent connection, ideal for high-pressure applications and environments where corrosion is a concern. They are also suitable for the given temperature range.
