Titanium Stub End

A lap joint stub end is a fitting that replaces welded flanges when the support of a rotating backup flange is required. Titanium stub ends can be supplied in standard and non-standard ANSI dimensions that connect pipes of different diameters.

 

We supply a wide range of Gr2 titanium stub end pipe fittings. Dimensional tolerances conform to ASME B16.9. Wall thicknesses conform to standard schedule 10S and 40S ASME B36.19M wall pipe.

 

Long function life

 

High mechanical strength

 

Stub ends are offered in three different ways, type A, B, and C. Type A and B stub ends are similar to forged fittings, such as elbows and tees, and type C stub ends are made in customized sizes.

 

Type A

 

The type A stub end is used for the standard lap joint flange. The lap thickness on the stub end is greater than or equal to the nominal thickness of the pipe wall. In addition, the outer corner radius of type A can meet the lap joint flange. The inside corner is square. Lap usually has a machined serrated face.

 

Type B

 

The type B stub end is used for standard slip-on flanges as lap flanges. The lap thickness on these short ends is greater than or equal to the nominal thickness of the pipe wall. Also, the outer corner radius of type B is small enough to receive the slip-flange that can be used as a backup flange. The inner corner is square. Lap usually has a machined serrated face.

 

Type C

 

The type C stub end can be used for standard lap joint flange and slip-on flange. It is flared leaving a rounded edge at the inside diameter of the lap. If necessary, the radius can be made close to a square. The lap thickness is 75% of the pipe wall. The type C is short enough to accommodate any backup flange. The lap joint on type C is smooth, and it is not to be machined.

 

Stub ends are usually manufactured in Type A and Type B. They are available in two standard lengths, long (ANSI) or short pattern (MSS).

Schedule 5s and 10s stub ends are usually offered in short lengths, and long lengths are available on special order. Schedule 40s stub ends are supplied in either short or long lengths.

 

a. Easy to prepare (does not require cut faces to be parallel or perfectly flat)

 

b. Can be formed between two dissimilar metals, such as aluminum and copper.

 

c. Accommodates different thicknesses (thinner piece must be welded on top), thin materials such as diaphragms and foils can be connected

 

Titanium and its alloy Stube Ends are widely used in medical and petrochemical equipment.

 

Pipe fittings include elbow, reducer, tee, cross, stub end, cap, etc. MSS SP43 TYPE-A titanium stub end is one kind of main product exported in large quantities.
