Ellipsoidal Head and Shell Joint Effeciency.
Ellipsoidal Head and Shell Joint Effeciency.
(OP)
I have a littel confusion with Compress concept with estimating the joint efficiency due to RT applied to Cat-B welds in 2:1 Ellip Heads and Cylinders.
Suppose;
Case 1: Head is seamless, RT for Circumferential weld between head and shell is Spot, and Shell is also Spot. What should be the E for head?
Case 2: Cylinder with Longitudinal seam Full RT, Circumferential seam Spot, what should be the E for the cylinder?

Case 1: Head is seamless, RT for Circumferential weld between head and shell is Spot, and Shell is also Spot. What should be the E for head?
Case 2: Cylinder with Longitudinal seam Full RT, Circumferential seam Spot, what should be the E for the cylinder?

1- Long. seam= 0,85
Circ. seam=0,85
1- RT 2 Long. seam= 1,00
Circ. seam=0,85
3- If Long. seam is full RT and head is also full RT, E should be 1.00.

Refer to Code paragraphs UW-12(a), UW-12(d), UW-12(e), and UW-11(a)(5).
Also to the joint efficiency flowcharts given in Appendix L and to the examples given in previous Editions of Appendix L (now in the separate publication).
