SECTION 165:26-6-40. Aboveground piping at airports

Latest version.

(a)   Aboveground product piping must be metal and rated for the system working pressure or at least 125 psi (860 kPa), whichever is greater.
(b)   Flanged connections or approved couplings must be provided to avoid the need for cutting and welding where components are serviced or replaced. Gaskets in flanged connections must be of a material and design that resist fire exposure for a time comparable to the flange and bolts.
(c)   Piping must be adequately supported.
