CASE

N-319-3CASES OF ASME BOILER AND PRESSURE VESSEL CODE

Approval Date: January 17, 2000

See Numeric Index for expirationand any reaffirmation dates.

Case N-319-3Alternate Procedure for Evaluation of Stresses inButt Welding Elbows in Class 1 PipingSection III, Division 1

Inquiry: What procedure may be used for evaluat-ing stresses in butt welding elbows per ANSI B16.9,MSS-SP87, or ANSI B16.28 in Class 1 pipe underSection III, Division 1, as an alternative to the stressindices and flexibility factors given in NB-3680?

Reply: It is the opinion of the Committee that theprocedure listed below may be used for evaluatingstresses in butt welding elbows per ANSI B16.9 MSS-SP87, or ANSI B16.28 in Class 1 pipe under SectionIII, Division 1.

1.0 LIMITATIONS OF APPLICABILITY

1.1 The elbows are welded on both ends to straightpipes of the same nominal thickness as the elbows,and the length of those straight pipes is not less thantwo times the nominal outside diameter of the elbow.

1.2 In conducting the piping system analysis(NB-3672.6), the flexibility matrix fij relating the dis-placement vector di to the force vector Fj accordingto the matrix equation

di p fij Fj; ij p 1,2,...,6,

where di is the column matrix of displacement compo-nents at end A of the elbow relative to end B (seeFig. 1.0)

di p {uxa , uya , uza , uxa , uya , uza },

and Fj is the column matrix of force components atend A

Fj p {Fxa , Fya , Fza , Mxa , Mya , Mza }
