Design of Copper Pipe

§ 192.125 Design of Copper Pipe#

(a)Copper pipe used in mains must have a minimum wall thickness of 0.065 inches (1.65 millimeters) and must be hard drawn.#

(b)Copper pipe used in service lines must have wall thickness not less than that indicated in the following table: Standard Size Inch#

(millimeter)Nominal O.D. Inch#

(millimeter)Wall Thickness, inch#

(millimeter)Nominal Tolerance ½ (13).625 (16).040 (1.06).0035 (.0889) ⅝ (16).750 (19).042 (1.07).0035 (.0889) ¾ (19).875 (22).045 (1.14).004 (.102) 1#

(24)1.125 (29).050 (1.27).004 (.102) 1 ¼#

(32)1.375 (35).055 (1.40).0045 (.1143) 1 ½#

(38)1.625 (41).060 (1.52).0045 (.1143)#

(c)Copper pipe used in mains and service line may not be used at pressures in excess of 100 p.s.i. (689 kPa) gage.#

(d)Copper pipe that does not have an internal corrosion resistant lining may not be used to carry gas that has an average hydrogen sulfide content of more than 0.3 grains/100 ft.3 (6.9/m3) under standard conditions. Standard conditions refers to 60°F and 14.7 p.s.i.a. (15.6°C and one atmosphere).#
