  1. Design (working) pressures are calculated in accordance with API 15LE specification.  A check should be made to determine if these pressures meet state and/or local codes.
  2. PE3608 pipes with different outside diameter, but the same DR have the same design (working) pressure ratings.
  3. Minimum pipe wall thickness is determined by dividing the pipe average outside diameter (OD) by the DR number.
  4. Meets or exceeds requirements of API 15LE, ASTM D2513 and PPI TR-4 Material Designation Code PE3608.
  5. ASTM D3350, Cell Classification PE345464C
