Aspects of Construction Covered by These Rules
(a) This Case contains rules for the construction of RTRP Class 3 piping, piping subassemblies, and appurtenances at temperatures not exceeding qualification conditions (-2600) (-4200) but in no case at temperatures greater than 180°F for polyester structural wall materials and 250°F for epoxy structural wall materials. Design pressures shall not exceed 500 psi for temperatures of 180°F and less or 250 psi for temperatures over 180°F not to exceed 250°F. Use of these materials is not permitted in continuous steam service at pressures over 5 psig.
(b) Terms relating to plastics and fiberglass shall be in accordance with Section X of the Code. Terms not covered in Section X shall be in accordance with ASTM D 883 or Appendix IV of this Case. The definitions of Appendix IV of this Case shall govern where there is a difference.
(c) The rules of Subsection NCA shall be met except as modified below:
