Page 54 - ... brazing may be dispensed with. Where copper pipes are expanded into or riveted to flanges, it will be necessary for the pipes with their flanges attached to withstand a hydrostatic pressure of two and one^half times the boiler pressure. Flanges shall be not less than four times the required thickness of pipe, plus one-fourth of an inch, and shall be fitted with such number of good and substantial bolts as shall make the joints at least equal in strength to all other parts of the pipe. Any form...

Page 54 - Flanges of cast steel, forged steel, or wrought iron may be used in any process of expanding the pipe into grooves in the bore of the flange and flaring the end of the pipe to an angle of 20 degrees.

Page 53 - Lap- welded steel and wroughtiron boiler tubes shall comply with the requirements of Subpart 66.20 of this subchapter for such tubes. (c) Seamless copper or brass tubes not exceeding three-fourths of an inch in diameter may be used in the construction of water-tube boilers or generators when liquid fuel is used. § 67.40-10 Computations — (a) Lapwelded and seamless tubes. Lap-welded and seamless tubes used in boilers whose construction was commenced after June 30, 1910, and having a thickness of...

Page 53 - No copper pipe constructed after June 30, 1905, shall have any bend whose radius is less than one and one-half times the diameter of the pipe and such pipe shall be so led and flanges so placed that they may be readily taken down if required. Such pipes shall be protected by iron casings when run through coal bunkers, and shall be clear of the coal chutes.

Page 53 - There may also be used in their construction, copper or brass steam drums not exceeding 14 inches in diameter, of a thickness of material not less than five-eighths of an inch, and copper or brass steam drums 12 inches in diameter and under having a thickness of material of not less than one-half inch. All tubes and drums referred to in this paragraph shall be made from ingots or blanks drawn down to size without a seam. Water-tube boilers or generators so constructed may be used for marine purposes...

Page 49 - The thickness of material, according to the working pressure, shall be determined by the following formula : where T= thickness in inches. P= working pressure. D= inside diameter of pipe in inches. EXAMPLE Required the thickness of material of a 5-inch copper pipe for a working pressure of 175 pounds per square inch. Substituting values, we have...
