GENERAL NOTES: (a) All dimensions are in millimeters (b) See Table 13 for tolerances. (c) Service conditions and joint construction often dictate stub end length requirements. Therefore, the purchaser must specify long or short pattern fitting when ordering. NOTES: (1) Gasket face finish shall be in accordance with ASME 816.5 for raised face flanges. (2) The lap thickness T shall not be less than nominal pipe wall thickness. See Table 13 for maximum tolerance. (3) When short pattern stub ends are used with larger flanges in Classes 300 and 600, with most sizes in Classes 900 and higher, and when long pattern stub ends are used with larger flanges in Classes 1500 and 2500, it may be necessary to increase the length of the stub ends in order to avoid covering the weld with the flange. Such increases in length shall be a matter of agreement between the manufacturer and purchaser. (4) When special facings such as tongue and groove, male and female, etc., are employed, additional lap thickness must be provided and such additional thickness shall be in addition to (not included in) the basic length F. (5) These dimensions conform to the radius established for lap joint flanges in.ASME 816.5. (6) This dimension conforms to standard machined facings shown in ASME 81-6.5. The back face of the lap shall be machined to conform to the surface on which it seats. Where ring joint facings are to be applied, use dimension K as given in ASME 816.5.

(2) Length El applies for thickness greater than that given in column "Limiting Wall Thickness" for NPS 24 and smaller. For NPS 26 and larger, length El shall be by agreement between the manufacturer and purchaser.

NOTES: (1) The value of tmin is whichever of the following is applicable: (a) the minimum ordered wall thickness of the pipe, to include pipe that is purchased to a nominal wall thickness with an undertolerance other than 12.5% (b) 0.875 times the nominal wall thickness of pipe ordered to a pipe schedule wall thickness that has an undertolerance of 12.5% (2) The maximum thickness at the end of the component is: (a) the greater of [tmi, + 4 mm (0.16 in.)] or 1.15tminwhen ordered on a minimum wall basis (b) the greater of [tmi, + 4 mm (0.16 in.)] or l.lOtn,, when ordered on a nominal wall basis (3) Weld bevel shown is for illustration only. (4) The weld reinforcement permitted by applicable code may lie outside the maximum envelope. (5) Where transitions using maximum slope do not intersect the inside or outside surfaces within the transition region, as shown by phantom outline, maximum slopes shall be used. Alternatively, radii lying within the envelope may be used.
