I. Socket Weld Fittings

When specifying piping classes with more than one class of socket weld fitting, what is the requirement for reducing fittings?

A) Specify the lower rating for reducing fittings
B) Specify the higher rating for reducing fittings
C) Use a different type of fitting for reductions
D) Ignore the rating for reducing fittings

Show Answer

Explanation: Reducing fittings shall be specified to the higher rating if dictated by the outlet pipe size schedule.

II. Swaged Nipples

What standard provides dimensions for swage nipples, and what should the end conditions of swage nipples follow?

A) ANSI B16.5; Custom end conditions
B) MSS SP-95; Pipe class requirements or Purchaser’s standard
C) ISO 9001; Any standard end conditions
D) ASME B31.1; Vendor-specific end conditions

Show Answer

Explanation: Dimensions for swage nipples are provided in MSS SP-95, and end conditions should follow pipe class requirements and/or Purchaser’s standard.

III. Reduction in Size for Socket Weld/Threaded Connections

For pipe classes using socket weld/threaded connections, how should reduction in size be achieved?

A) By increasing the pipe size
B) By using a different material
C) By using a swage nipple
D) By welding the connections directly

Show Answer

Explanation: Reduction in size for socket weld/threaded connections shall be by swage nipple.

IV. Butt Weld and Small-Bore Socket Weld/Threaded Connections

For pipe classes with a combination of butt weld and small-bore socket weld/threaded connections, how should reductions be made?

A) By using larger socket weld fittings
B) By using swage nipple; maximum size of large end NPS 4
C) By using threaded connections only
D) By ignoring the combination and using one type of fitting

Show Answer

Explanation: Reductions from butt weld to socket weld/threaded shall be made by swage nipple; the maximum size of the large end shall be NPS 4.

V. Butt Weld End Conditions

How should all other reductions within the butt weld end conditions be made?

A) By using threaded connections
B) By using butt weld reducer type fitting
C) By increasing the pipe size
D) By using larger socket weld fittings

Show Answer

Explanation: All other reductions within the butt weld end conditions shall be made by butt weld reducer type fitting.

VI. Seamless/Welded Execution

What should be the execution of fittings concerning seamless/welded in comparison to the pipe of the same size in the pipe class?

A) It does not matter
B) It should be the opposite
C) It should be the same
D) It should be based on the vendor’s preference

Show Answer

Explanation: Seamless/welded execution of fittings shall be the same as that of pipe of the same size in the pipe class.

VII. Material Certificates

What standard should material certificates for fittings comply with?

A) ISO 14001
B) ASME B16.9
C) BS EN10204, 3.1
D) API 650

Show Answer

Explanation: Material certificates for fittings shall comply with BS EN10204, 3.1.
