Stainless steel lap joint stub end is a type of fitting used in piping systems. It is designed to be used with a lap joint flange in order to connect two sections of pipe.

The stub end is made from stainless steel, which is a highly durable and corrosion-resistant material that is commonly used in a wide range of industrial applications. The lap joint design allows for easy alignment and installation, while the stub end itself is designed to provide a secure and leak-proof seal.

Stainless steel lap joint stub ends are available in a range of sizes and thicknesses to accommodate a variety of piping systems. They are commonly used in high-pressure and high-temperature applications, as well as in corrosive environments where resistance to corrosion is essential.

Overall, stainless steel lap joint stub ends are a highly versatile and reliable pipe fitting that can be used in a wide range of industrial applications.

Lap Joint Stub End Types

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

Tipo A

The Type A lap joint Stub end is employed for standard joint flange. The lap thickness on the stub end is bigger than or up to the nominal thickness of pipe wall. Additionally, the outer corner radius of the sort A will receive the lap joint flange. The within corner is square. Lap sometimes includes a machined rough face.

Tipo B

The Type B lap joint Stub end is employed for standard slip on flanges as lap flanges. The lap thickness on these short ends is bigger than or up to the nominal thickness of pipe wall. Also, the outer corner radius of type B is tiny enough to receive the slip o flange which will be used as a backup flange. The inner corner is square. Lap sometimes includes a machined rough face.

Tipo C

The Type C lap joint Stub end will be used for standard lap joint flange, and put on flange. It’s flaring feat a rounded edge at the within diameter of the lap. If necessary, the radius will be created closed to a square. The lap thickness is 75th of the pipe wall. The sort C is very short enough to accommodate any backup flange. The lap joint on kind C is smooth, and it’s not machined.
