Extreme-Pressure Iron and Steel Threaded Pipe Fittings

The strongest steel fittings we offer, these can withstand extreme-pressure applications.

Note: The maximum pressure listed for Class 6000 fittings is for conditions where there are no sudden changes in pressure or velocity. Please refer to ASME B16.11 to determine the specific maximum operating pressure for your application.

Extreme-Pressure Stainless Steel Socket-Connect Pipe Fittings

The strongest socket-connect fittings we offer, these heavy duty forged fittings are also known as Pressure Class 6000. They are easier to weld than butt-weld fittings because the fitting doesn’t need to align perfectly to the pipe. Slide pipe into the socket and weld for a strong, permanent connection.

304/304L Stainless Steel—Fittings hold up in humid, damp, and washdown environments but will corrode if exposed to salt water or chemicals.

316/316L Stainless Steel—Fittings are the most corrosion resistant. They stand up to wet environments, just like 304 stainless steel fittings, but unlike 304 stainless steel, they will not corrode from salt water, chlorine solutions, and chemicals.

High-Pressure Iron and Steel Threaded Pipe Fittings

These fittings can stand up to high-pressure applications. Use them in noncorrosive environments.

Note: The maximum pressure listed for Class 3000 fittings is for conditions where there are no sudden changes in pressure or velocity. Please refer to ASME B16.11 to determine the specific maximum operating pressure for your application.

Extra-Thick-Wall Stainless Steel Unthreaded Pipe Nipples and Pipe

With an extra-thick wall, this Schedule 160 pipe is the strongest stainless steel pipe we offer. Weld it to fittings and additional lengths of pipe. Welded connections are stronger than threaded connections and less likely to leak.

Pipe—Unthreaded

304 Stainless Steel—Pipe holds up in humid, damp, and washdown environments but will corrode if exposed to salt water or chemicals.

316 Stainless Steel—Pipe is the most corrosion resistant. It stands up to wet environments, just like 304 stainless steel pipe, but unlike 304 stainless steel, it will not corrode from salt water, chlorine solutions, and chemicals.

Seamless—Pipe has a smooth interior for unrestricted flow and is stronger than welded pipe.

Extreme-Pressure Iron and Steel Threaded Pipe Flanges

Also known as Pressure Class 1500 flanges, these have the strength to handle high pressures. Bolt two same-size flanges together with a gasket (sold separately) to create an access point within a line. Flanges are for use in noncorrosive environments.

Forged Flanges

Extreme-Pressure Iron and Steel Unthreaded Pipe Flanges

For excellent strength in extreme-pressure applications, choose these heavy duty Pressure Class 1500 flanges. Bolt two same-size flanges together with a gasket (sold separately) to create an access point in a pipe line. They are for noncorrosive environments.

Forged Flanges


Butt Weld: Front	Butt Weld: Raised Surface on Back	Slip-On Weld Female: Front

Slip-On Weld Female: Raised Surface on Back	Socket-Connect Female: Front	Socket-Connect Female: Raised Surface on Back

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.
