Σελίδα 592 - The permissible variation in weight is 5 per cent above and 5 per cent below. Furnished with threads and couplings and in random lengths unless otherwise ordered. Taper of threads is \" diameter per foot length for all sizes.
Σελίδα 595 - Taper of threads is 3 inch diameter per foot length for all sizes. The weight per foot of pipe with threads and couplings is based on a length of 20 feet, including the coupling, but shipping lengths of small sizes will usually average less than 20 feet. All weights given in pounds. All dimensions given in inches.
Σελίδα 595 - All weights and dimensions are nominal The permissible variation in weight is 5 per cent above and 5 per cent below. Furnished with threads and coupling» and in random lengths unless otherwise specified.
Σελίδα 662 - These results again demonstrate that taken on the average there is no difference in the corrosion of iron and steel pipe. Conversations held with tie engineers in charge of plants during this investigation confirm the statement .already made that a pipe is frequently called steel when corrosion is found to be excessive, while it is set down as iron if it rusts but little.
Σελίδα 559 - On the corrosion of locomotive boilers and the means of prevention. 8,800 w. 1ll. 1866. (In Proceedings of the Institution of Mechanical Engineers, v. 17, p. 56.) Considers corrosion due both to chemical action of water and mechanical action of strain. The trouble may be obviated by removing one of these causes, ie, by proper boiler design, eliminating springing at joints, etc. La Coux, H. de. Eaux corrosives et incrusto-corrosives dans les generateurs de vapeur. 14,500 w. 1899. (In Le Genie Civil,...
Σελίδα 662 - In my judgment, from the evidence collected, there was absolutely no difference in the corrosion of the two classes of pipe. They appeared to be equally susceptible to the attack.
Σελίδα 671 - If cut lengths of any sizes are ordered instructions must appear on the face of the order whether plain ends, threads only or threads and couplings are required. The mill then cuts the pipe proper to the length specified for plain ends...
Σελίδα 557 - Rust in galvanized iron water service pipe. 6,000 w. 1909. (In Metal Worker, v. 71, March 27, p. 48; April 3, p. 52; April 10, p. 45; April 17, p. 48; April 24, p. 39.) Continued discussion, by lette'r, in reply to questions by editor concerning the presence and prevention of corrosion in water-pipe. Siebel, EP Pitting of iron, particularly pipe; its causes and possible preventives. 3,000 w.
Σελίδα 559 - Ill. 1904. (In Journal of the American Society of Naval Engineers, v. 16, p. 529.) The same, condensed. 1,000 w. (In Iron and Steel Magazine, v. 10, p. 349.) Extensive experiments made for the United States Navy Department at the laboratory of the National Tube Co., McKeesport, to determine relative corrodibility of lap-welded Bessemer steel, lapwelded iron, seamless cold-drawn steel and seamless hot-drawn steel boiler tubes.

Σελίδα 567 - This test checks up well with the aforesaid 1908 paper, and we believe demonstrates that modern steel pipe of good quality is, at least, as durable as modern strictly wrought iron pipe of good quality, and is very much superior to a poor quality of wrought iron in this class of work.
