Foreword T o the engineer responsible for the design and operation

o f safe and ef f ic ient piping systems, th is "Datalog" i s pre- sented wi th the hope that i t w i l l fac i l i ta te the burdensome tasks pecul iar to piping layout.

Painstaking efforts have been made to assemble such standards, technical data, charts and recommendations as are necessary for him to cope wi th the diverse problems i n Power P lan t and Industrial Piping, many of which, due to the trend toward higher pressures and temperatures, are o f a h ighly special ized nature.

The "Datalog" divides i tse l f into two sections, the f i r s t of which i s devoted almost entirely to dimensions and general notes wi th reference to fabricat ion and shop practice. The Standards shown are those approved by recognized engineering groups such as the American Standards Associa- tion, American Society for Test ing and Materials, American Society of Mechanical Engineers, American Welding Society, P ipe Fabricat ion Inst i tute and others. The data contained herein are those as taken from the most recent issues of these Standards.

The Technical Section, which begins on page 165, includes technical data, charts and recommendations, which, we be1 ieve, conform wi th the most stringent engineering practice. A great part of th i s information i s the resul t o f tests and investigations conducted by our own Research Department, supplemented by a background of successful performance i n industry.

The knowledge of piping which we have gained in over a half-century has not been confined to design and fabrication alone, but includes a wide f i e l d experience in erecting, test ing and placing in operation, p ip ing systems for every power plant and industr ial need. The publ ishing of th i s book has been actuated by our desire to convey to the En- gineering Fraternity and to the buyers and users of piping, the knowledge gained by extensive research and operation throughout that period.

Physical and Chemical Data for Piping Materials

T h i s section of the DATALOG covers physical dimensions and properties, chemical properties, manufacturing tolerances, pressure-temperature ratings, etc. for the moior types of piping components. Some of the equipment items are pipe materials, welding fitt ings, flanges and flanged fitt ings, valves, expansion joints, bolts and gaskets. Some fabrication data are included such as bending radii, arc lengths, and minimum tangents; welding data such as end bevel and backing details, machining detoi ls such as flange facings, dril l ing, etc.

A l l dimensions ore i n inches.

Thicknesses shown bold face denote "Standard Weight" (STD) pipe; those i n i ta l ics "Extra Strong" (XS) pipe. Additional wal l thicknesses for these weight c lassi f icat ions are shown below as they do not coincide with a schedule number i n ASA 036.10.

I t should be noted that i n sizes 1/8" through lo f f , schedules 40, 405 and "Stand- ard Weifhi" are identicol; however, i n sizes 12 and larger, .37511 wol l thickness i s "Standard Weight". L ikewise i n sizes 1/8" through 8". schedules 80, 80s and "Extra Strong" are identicol, and i n sizes 10" and larger .5001' wal l thickness i s "Extra Strong".

NOTES:

Schedules 10 through 160 and "Double Extra Strong" are i n ac.

The di f ferent grades of stainless steel permit considerable vori- ot ionr i n weight. The ferr i t ic stainless steels may be about 5 per cent less, and the oustenit ic stainless steels about 2 per cent greater than the weights for corresponding sizes of carbon steel pipe. (Refer to pages 12 through IS).


(' Wall Thickness Calculations And Working Pressures For Pipe j

Due ta the fact that metals i n general lose strength as service temperatures increase, the ASME Boiler and Pressure Vessel Code, Section I, Power Boi lers, and the ANSl Code for Pressure Piping, 831.1, Power Piping, have estobj ished safe working stresses for mast materials used, based on the service temperature. Al lowable stress values for the various grades of pipe most cammonly used i n Power Pip ing are shown on pages 18 through 21, c lass i f ied under the appl icable ASTM specification. These tobu- lot ions cover ol lowable stresses (SE) for bath the Boi ler Code, Section I and 831.1 Pawer Piping Code at temperatures ranging from -20F to 1500DF, wi th the 1250 t o 1500F range applying to the Boi ler Code only. I t should be noted also that the Bai ler Code indicates al lowable stresses for some of the materials ot temperatures higher than those al lowed i n the Power Piping Code, 831.1, which are tabulated here. Similarly, the Code for Pressure Pip ing a l lows higher warking stresses for Petroleum Refinery Piping i n ANSl 831.3, Gas Transmission and Dis t r ibut ion Piping in ANSl 831.8, Industr ial Gas and Air Piping, etc. For al lowable stresses for these code iurisdict ions, the designer i s referred ta the appl icable code.

The fo l lowing formulae shal l be used in determining minimum pipe wal l thi,cknesses required for known pressures at given temperatures, or for ca lcu lat ing maximum al lowable working pressures for known miiiimum wa l l thicknesses at given temperatures.

tm = Minimum required w a l l thickness i n incht:s.(4), NOTE - The relot ionship between tm and "nomina-I w a l l

thickness" must take in to account the manufactur ing tolerance on wal l .

P = Internal design pressure, ps i gage NOTE - When computing al lowable working pressure for

pipe wi th a defini te minimum wa l l thickness, the value of P may be rounded out to the next higher uni t of 10.

D or Do = Outside diameter of pipe in inches. SE = Maximum al lowable stress in pipe wa l l due t o in-

The value of SE shal l not ex - ceed that given on pages 18 thru 21 for the respec- t ive material a t the design temperature. SE values shown include an ef f ic iency of 1.0 for seamless pipe and ioint factors set up by the codes for longi- tudinal ly welded pipe.

Carbon steel, low a l loy steels and a u s t e n i t ~ c steels are shown for the grades commonly used i n Power P i p i n g Systems w i th in the scope of the ANSl Code for Pressure Piping, 831.1. The 0 1 lowable working pressures tabulated are based on the ANSl P ip ing Code 831.1 formulo on page 17, us ing a l lowable stresses as shown on pages 18 thru 21 for the appl icable ASTM Speci f icat ions a t the various temperatures.
