Pipe Need to Know

yield & tensile info

Used Steel Pipe: #1 and #2 These classifications are typically used to 

describe the appearance of the pipe.


Grade #1 includes pipe that has no pitting or visible defects on the exterior or interior of the pipe.  Although there should be no visible pitting or defects, the #1 pipe may have what is referred to as a “Salt & Pepper” description.  This description can be concluded simply by touching the pipe.  You will actually be able to feel a sandpaper-like finish on the pipe that is caused from weather.


Grade #2 includes pipe that will have a bit more oxidation pitting, but no heavy duty “crater” pitting should be detected. 


Culvert Grade includes pipe that as having one or all of these characteristics: bows, dings, or dents along with wrinkles & pitting.


There are many different jobs used for Culvert Pipe.

Some of the most common would be for drainage, cattle troughs, creek crossings, and flume pipe on construction sites for heavy machinery to run over so they do not get stuck in the mud.
