Use A dimension when the adjacent diameter to the left of plane B-B is greater than J dimension. When t
9、he adjacent diameter is equal to or less than J dimension, M dimension may be used in place of A dimension. 2. Any design of the elbow to the left of plane B-B is acceptable provided the dimensions P and U and the requirements of this specification sheet and the procurement specification are met. 3.
10、 Any forged design is acceptable for -3/-4 through -8 size. 4. Any bent tube design is acceptable for -10 through -24 size. The inside diameter (ID) of the elbow for the -10 through -24 sizes shall not be less than the ID of the nipple end of the adapter. 5. Ovality shall not exceed 7.5 percent of n
11、ominal tubing OD. 6. Unless otherwise specified, break or radius all corners .005, +.005, -.000 inch. 7. All diameters within length A plus S must be concentric within .005 inch total indicator movement. 8. Unless otherwise specified, maximum surface roughness shall not exceed 125 in. Ra in accordan
