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.

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 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.

WP316L SMLS Stub End

What are they?

WP316L SMLS 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.

WP316L SMLS STUB ENDs' Types

WP316L SMLS 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.

WP316L SMLS STUB ENDs are available in two standard lengths, MSS and ANSI.

WP316L SMLS STUB ENDs are normally provided with a standard weld bevel

WP316L SMLS STUB ENDs dimensions are found on our fitting dimensions page.

service to customers that require something non-standard. This may be something simple like a reduction in the bore of the product to meet a higher working pressure, an increase of the thread lengths, the use of exotic materials or simply you have a fitting and you don’t know where to get it from, we can reverse engineer the product and create it exactly as the sample.We have had many requests throughout the years for some of the very bespoke and unusual requests for Non-Standard Fittings and Custom Fittings. No matter how complicated we like the challenge.

If you have a Non-Standard Fittings or Custom Fittings request and we say we cannot make it then it simply cannot be done.
