China STUB END Manufacturer Yaang offers MSS SP-43 type A ASTM B366 Alloy 601 Butt Welded Stub End, 4 Inch, SCH10S.

Inconel 601 is a nickel-chromium alloy used for applications that require resistance to corrosion and heat. This nickel alloy stands out due to its resistance to high temperature oxidation, remaining highly resistant to oxidation through 2200° F. Alloy 601 develops a tightly adherent oxide scale which resists spalling even under conditions of severe thermal cycling. This nickel alloy has good high temperature strength, and retains its ductility after long service exposure. It has good resistance to aqueous corrosion, high mechanical strength, and is readily formed, machined and welded. Inconel 601’s properties make it a material of broad utility in fields like thermal processing, chemical processing, pollution control, aerospace, and power generation. However, alloy 601 is not suggested for use in strongly reducing, sulfur bearing environments.

STUB END

Alloy 601 Stub End

What are they?

Alloy 601 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.

Alloy 601 Stub Ends' Types
Alloy 601 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.
Alloy 601 Stub Ends are available in two standard lengths, MSS and ANSI.
Alloy 601 Stub Ends are normally provided with a standard weld bevel.
Alloy 601 Stub Ends dimensions are found on our fitting dimensions page.
