subsections#
(b),#
(c), and#
(d), the design factor to be used in the design formula in section 6-77-29 is determined in accordance with the following table: ________________________________________________________ Class location │ Design factor (F) │ │ 1................................│ 0.72 2................................│ 0.60 3................................│ 0.50 4................................│ 0.40 │#
(b)A design factor of 0.60 or less must be used in the design formula in section 6-77- 29 for steel pipe in Class 1 locations that:#
(1)Crosses the right-of-way of an unimproved public road, without a casing;#
(2)Crosses without a casing, or makes a parallel encroachment on the right-of-way of either a hard surfaced road, a highway, a public street, or a railroad;#
(3)Is supported by a vehicular, pedestrian, railroad, or pipeline bridge; or#
(4)Is used in a fabricated assembly, (including separators, mainline valve assemblies, cross-connections, and river crossing headers) or is used within five pipe diameters in any direction from the last fitting of a fabricated assembly, other than a transition piece or an elbow used in place of a pipe bend which is not associated with a fabricated assembly.#
(c)For Class 2 locations, a design factor of 0.50, or less, must be used in the design formula in section 6-77-29 for uncased steel pipe that crosses the right-of-way of a hard surfaced road, a highway, a public street, or a railroad.#
(d)For Class 1 and Class 2 locations, a design factor of 0.50, or less, must be used in the design formula in section 6-77-29 for:#
(1)Steel pipe in a compressor station, regulating station, or measuring station; and#
(2)Steel pipe, including a pipe riser, on a platform located offshore or in inland navigable waters. [Eff ] (Auth: HRS '269-6) (Imp: 49#
