    Also known as Schedule 10 pipe stub ends, these are thin and lightweight. They have beveled ends that, when flush to pipe, create a trough for a strong weld that permits maximum flow.
    Pipe stub ends are used with flanges. Slide a flange onto the stub end and weld the stub end to pipe (not the flange). Since the flange isn’t welded to the pipe, it can be disconnected easily, which creates an access point for frequent cleaning and inspecting.
    304/304L Stainless Steel—304/304L stainless steel pipe stub ends have very good corrosion resistance.
    316/316L Stainless Steel—316/316L stainless steel pipe stub ends have excellent corrosion resistance.

    Stub-end straight adapters are used with flanges. Slide a flange onto the stub end and weld the stub end to pipe (not the flange). Since the flange isn’t welded to the pipe, it can be disconnected easily, which creates an access point for frequent cleaning and inspecting.

    Butt-weld pipe stub ends allow for a smooth connection that provides maximum flow. They have beveled ends that, when flush to pipe, create a trough for a strong, permanent weld. Pipe stub ends are also known as Schedule 40. They are for use in noncorrosive environments.
    Pipe stub ends are used with flanges. Slide a flange onto the stub end and weld the stub end to pipe (not the flange). Since the flange isn’t welded to the pipe, it can be disconnected easily, which creates an access point for frequent cleaning and inspecting.

    With thicker, stronger walls than our standard-wall butt-weld pipe stub ends, these stand up to your high strength applications. Weld them flush against pipe for a smooth connection that permits maximum flow. These stub ends have beveled ends that create a trough for a leak-resistant, permanent weld. Made of steel, they’re for use in noncorrosive environments.
    Pipe stub ends are used with flanges. Slide a flange onto the stub end and weld the stub end to pipe (not the flange). Since the flange isn’t welded to the pipe, it can be disconnected easily, which creates an access point for frequent cleaning and inspecting. Bolt flanges together with a gasket.
