1. Which tool is commonly used to create precise bevels on pipe ends for welding?

2. What is the standard included angle for a pipe weld bevel?

3. What device is installed between a control valve and the air supply header?

4. Which reducer produces a center discharge?

5. How is the centerline of a pipe typically marked for cutting?

6. Which tool is used to align two pipes for welding?

7. The travel is 11’ – 3 ¾”. There will be a 45° angle. What is the offset distance?

8. Convert 1/4 to its decimal equivalent.

9. Pipe fabrication requires the use of both welding and threading techniques.

10. A hydrostatic test is performed to check for leaks in fabricated pipe systems.

11. Stainless steel is more prone to corrosion than carbon steel in most environments.

12. The heat-affected zone (HAZ) is a concern in pipe welding because it can weaken the metal.

13. During fabrication, pipes should always be cut longer than the specified length to allow for adjustments.

14. At and above what nominal pipe size is the O.D. of the pipe the same as the nominal size of the pipe?

15. Which type of field sketch has base lines that are 30° to the horizontal axis?

16. What must be done to MOST socket welded valves before being welded into place?

17. What is the length of pipe required to fabricate a 6'' s/40 pipe spool with one class 150# RFWN flange on one end, and one class 300# RFWN flange on the other end, with a face-to-face measurement of 1’ - 6 1/2'' (assume a 1/8 welder gap)?

18. The angles of any triangle add up to

19. All the following drawing dimensions are used to determine the overall length of a pipe run EXCEPT:

20. What is the purpose of a purge gas when welding stainless steel pipe?
