Sizing. Since pipes can come in a variety of shapes and sizes, the specifications also define the proper sizing of a pipe marking. The size of a pipe marking label is set based on the pipe diameter as follows: ¾ – 1 ¼" = at least 8" in length and ½" in height. 1 ½ – 2" = at least 8" in length and ¾" in height.Web

The coarsest material standard for frac sand is 20/40. This means that 90 percent of the sand is fine enough to pass through a 20 mesh sieve (see sieves etc) and is coarse enough to be retained on a 40 mesh sieve. As long as your sand meets these requirements, you have 20/40 frac sand. Some other common standard sizes are …Web
