Note:
1. Thickness shall not be less than 87.5% of Nominal Wall Thickness
2. All Dimensions are in MM Unless & Otherwise Specified
3. Service conditions and joint construction often dictate stub end length requirements. therefore, the purchaser must specify long or short.
4. Gasket face finish shall be in accordance with ASME B16.5 for Raised face flange.
5. The lap thickness T, Shall Not be less than Nominal pipe wall thickness.
6. When short pattern stub ends are used with large flange in #300 & #600, with most sizes in #900 & higher, and when long pattern stub end are used with large flanges in #1500 & #2500, it may be necessary to increase the length of stub ends in order to avoid covering the weld with the flange. Such increase in length shall be a matter of agreement between the manufacturer and purchaser.
7. When special facings such as tongue & groove or male & female are employed, additional lap thickness must be provided and such additional thickness shall be in addition to (not included in) the basic length, F.
8. These dimensions conform to the radius established for lap joint flanges in ASME B16.5.
9. This dimension conforms to standard machined facings shown in ASME B16.5. The back face of the lap shall be machined to conform to the surface on which it sits, where ring joint facings are to be applied, use dimension K as given in ASME B16.5
