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: Air, Water, Hydraulic Fluid, Natural Gas, Steam, Oil
Specifications Met: ASTM A312
Fittings: Use Class 6000 or Schedule 160 stainless steel

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 is seamless, which provides a smooth interior for unrestricted flow.

304 stainless steel pipe has very good corrosion resistance. 316 stainless steel pipe has excellent corrosion resistance.

Thick-Wall Stainless Steel Unthreaded Pipe

For Use With: Air, Water, Hydraulic Fluid, Natural Gas, Steam, Oil
Specifications Met: ASTM A312
Fittings: Use Class 3000 or Schedule 80 stainless steel
Flanges: Use Class 300 or 600 stainless steel

Also known as Schedule 80, this pipe provides an extra-strong connection. Weld it to fittings and additional lengths of pipe. Welded connections are stronger than threaded connections and less likely to leak. Pipe is seamless with a smooth interior for unrestricted flow.

304 stainless steel pipe has very good corrosion resistance. 316 stainless steel pipe has excellent corrosion resistance.
