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 B16.5 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 B16.5.
  • (6) 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 seats. Where ring joint facings are to be applied, use dimension K as given in ASME B16.5.

317L Stub End

What are they?

317L Stub Ends are fittings used in place of welded flanges where rotating back up flanges are desired.

They are also called Lap Joints and Vanstone Flared Laps.

How do they work?

A rotating back up flange seats itself against the back surface of the Stub End. When bolts are added, the clamping action of the bolts presses the rotating back up flange against the back of the Stub End. The gasket surface of the Stub End then presses against a gasket and another gasket surface providing joints like standard flange joints. The seal is made by the gasket surface of the stub end alone, the flange only provides the clamping pressure on the joint.

Why?

Since Stub Ends are made from material compatible with the designed piping system, back up flanges do not have to be made from the same material. The flange can be made from less expensive material because it never comes in contact with the process fluid.

317L Stub Ends' Types
317L Stub Ends are typically manufactured by two methods. Type A & B Stub Ends are made similar to forged fittings such as Elbows and Flanges. Type C Stub Ends are made by forming pipe to the desired dimensions.
317L Stub Endare available in two standard lengths, MSS and ANSI.
317L Stub Endare normally provided with a standard weld bevel
317L Stub Enddimensions are found on our fitting dimensions page.
