How to Identify and Measure Fittings

Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

For Use With:
Steel: Air, Hydraulic Fluid, Natural Gas, Oil, Steam, Water
P22 Chrome-Moly Steel: Air, Natural Gas, Oil, Steam, Water
Specifications Met: See table
Fittings:
Steel: Use Class 3000 or Schedule 80 steel
P22 Chrome-Moly Steel: Use Class 3000 F22 Chrome-Moly Steel
Flanges:
Steel: Use Class 300 or Class 600 Steel

Thick, Schedule 80 walls give this pipe better strength than our standard-wall steel unthreaded pipe. Weld it to fittings and additional lengths of pipe. Welded connections are stronger than threaded connections and less likely to leak. Pipe is seamless, so it has a smooth interior for unrestricted flow. It is for use in noncorrosive environments.

P22 chrome-moly steel is stronger and easier to weld than plain steel. It resists scaling even in steam applications.

Rotary Shafts

Combine these general purpose drive shafts with gears, sprockets, and bearings to transmit rotary motion. All are turned, precision ground, and polished to meet tight diameter and straightness tolerances. This means these shafts evenly distribute loads, reduce vibration, and improve accuracy and stability.

Steel shafts are generally stronger than stainless steel shafts but not as corrosion resistant. Alloy steel shafts are good for high-stress applications. They are stronger than carbon steel and hardened for increased wear resistance; however, they are more difficult to machine.

Shafts with chamfered edges reduce damage to bearings, housings, and other components during installation.

Keyed Rotary Shafts

Combine these shafts with a machine key (not included) to transmit torque to gears, sprockets, and other power transmission components. All have an ANSI standard keyway (keys not included; see our selection of key stock). Their edges are chamfered to remove sharp corners, reducing damage to bearings, housings, and other components during installation. All are turned, ground, or polished to tight diameter and straightness tolerances.

Steel shafts are generally stronger than aluminum and stainless steel shafts but not as corrosion resistant. 4140 alloy steel shafts are good for high-stress applications. They are stronger than carbon steel and hardened for increased wear resistance; however, they are more difficult to machine.
