Testimonial

The successes we both have had in designing and building equipment to meet the special requirements of our customers has been very rewarding. I appreciate everything you have done to make this possible. The personal relationship we have developed has been very important and meaningful to me. I have very high regard for your analytical and problem solving ability in achieving an objective and creating solutions to problems.

SDR Pipe Reference

Select Mechanical or Inflatable Pipe Plugs based on the below pipe ID and along with the pressure to be blocked

(PETERSEN DOES NOT SELL PIPE)

SDR = "Standard Dimension Ratio" is used by many PE pipe manufacturers as a method of rating pressure piping. SDR is a ratio of pipe diameter to wall thickness and can be expressed as SDR = D/s

SDR 11 means that "D" outside diameter of the pipe is eleven times the thickness "s" of the wall.

With a high SDR ratio the pipe wall is thin compared to the pipe diameter and will have a low pressure rating.

With a low SDR ratio the pipe wall is thick compared to the pipe diameter and will have a high pressure rating.

SDR

D = pipe outside diameter (mm)
s = pipe wall thickness (mm)

The following tables represent the dimensional specifications for ASTM D3035, ASTM F714 and ASTM F2160 for OD controlled inner duct.
