    About Pipe and Fittings
    industrial info icon

    Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

    Low-Pressure Iron and Steel Threaded Pipe Flanges

    Create an access point in low-pressure lines. To install, bolt two flanges of the same size together with a gasket (not included). Made of iron or steel, flanges perform best in noncorrosive environments.

    Forged flanges have better strength than cast flanges.
    A350 Carbon Steel—Even in temperatures as low as -46° F, these flanges won’t become brittle, so they absorb impact better than other low-pressure steel flanges.

    Forged flanges have better strength than cast flanges.
    Reducing flanges allow you to transition your system to a smaller pipe size; attach to a flange with a larger pipe size but with the same flange dimensions.

    Low-Pressure Iron and Steel Unthreaded Pipe Flanges

    Create an access point in a low-pressure pipeline. Bolt two flat-surface flanges or two raised-surface flanges of the same size together with a gasket (not included). Flanges are steel and perform best in noncorrosive environments.

    Butt-Weld Fitting Connection—Butt-weld flanges are also known as weld-neck flanges; the flange neck has a beveled end that, when flush to pipe, creates a trough for a strong weld.
    Slip-on-Weld Fitting Connection—Slip-on weld flanges have no internal stop; slide a pipe through the flange and weld on both sides.
    Stub-End Fitting Connection—Stub-end flanges are also known as lap-joint flanges. Use them with a stub-end straight adapter (not included). The stub-end straight adapter slides into the flange and welds to pipe (not the flange). Since the flange isn’t welded to the pipe, it can be disconnected easily for frequent cleaning and inspecting.

    Stub-End Straight Adapters

    Straight Adapter

    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.

    High-Pressure Stainless Steel Unthreaded Pipe Flanges

    These heavy duty forged flanges create an access point in a high-pressure pipeline. Bolt two flat-surface flanges or two raised-surface flanges of the same size together with a gasket (not included). Flanges are made of stainless steel for excellent corrosion resistance.

    Butt Weld

    Slip-On

    Socket-Connect

    Forged flanges have better strength than cast flanges.
    Butt-Weld Fitting Connection—Butt-weld flanges are also known as weld-neck flanges; the flange neck has a beveled end that, when flush to pipe, creates a trough for a strong weld.
    Slip-on-Weld Fitting Connection—Slip-on weld flanges have no internal stop; slide a pipe through the flange and weld on both sides.
    Stub-End Fitting Connection—Stub-end flanges are also known as lap-joint flanges. Use them with a stub-end straight adapter (not included). The stub-end straight adapter slides into the flange and welds to pipe (not the flange). Since the flange isn’t welded to the pipe, it can be disconnected easily for frequent cleaning and inspecting.
    304/304L Stainless Steel—Flanges hold up in humid, damp, and washdown environments but will corrode if exposed to salt water or chemicals.
    316/316L Stainless Steel—Flanges are the most corrosion resistant. They stand up to wet environments, just like 304 stainless steel flanges, but unlike 304 stainless steel, they will not corrode from salt water, chlorine solutions, and chemicals.

    Forged flanges have better strength than cast flanges.
    304/304L Stainless Steel—Flanges hold up in humid, damp, and washdown environments but will corrode if exposed to salt water or chemicals.
    316/316L Stainless Steel—Flanges are the most corrosion resistant. They stand up to wet environments, just like 304 stainless steel flanges, but unlike 304 stainless steel, they will not corrode from salt water, chlorine solutions, and chemicals.

    Straight Adapter

    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.

    Extreme-Pressure Iron and Steel Threaded Pipe Flanges

    Create an access point in extreme-pressure lines. Also known as Pressure Class 1500 flanges, bolt two of the same size together with a gasket (not included). These flanges are made of iron or steel, so they're best for noncorrosive environments.

    Forged flanges have better strength than cast flanges.
    Butt-Weld Fitting Connection—Butt-weld flanges are also known as weld-neck flanges; the flange neck has a beveled end that, when flush to pipe, creates a trough for a strong weld.
    Slip-on-Weld Fitting Connection—Slip-on weld flanges have no internal stop; slide a pipe through the flange and weld on both sides.
