PA1104 ASTM A-120 A123/A123M STEEL SERVICE PIPING SYSTEM



Specification for Pipe, Steel, Black and Hot-Dipped Zinc-Coated (Galvanized) Welded and Seamless for Ordinary Uses (Withdrawn 1987).
This Standard Specification covers individual steel pieces as well as assemblies of various classes of material. The material categories covered in the specification include structural steel and plate, strips and bars, pipes and tubing, and wires. Fabrications can have more than one material category, such as a frame assembly. Any combination of these products can be assembled into a single fabrication and then hot-dip galvanized.

The requirements listed in ASTM A123/A123 M include coating thickness, finish, appearance, and adherence. The specification requirements for coating thickness only contain minimums, there is no maximum coating thickness limitation in the specification. The finish requirement is continuous, smooth, and uniform, while appearance requires no uncoated areas or issues that interfere with the fabrication’s intended use. Finally, the adherence requirement is for the entire coating to have a strong adherence throughout the service life of the galvanized steel.



PIPE INSTALLED OUTSIDE A BUILDING • The pipe prices above are for plain end pipe • For pipe installed on Sleepers at grade and run to a terminal connection, deduct 15% from Manhours shown. • For pipe installed under a Concrete Slab on grade, prior to concreting, and run to a terminal connection, add 6% to Manhours shown. • For pipe installed on Pipe Racks to 12'0" above grade and run to a terminal connection, add 15% to Manhours shown. • For pipe installed in a completed Concrete Tunnel and run to a terminal connection, add 100% to Manhours shown.
PIPE INSTALLED INSIDE A BUILDING • A-106 carbon steel pipe in pipe spools erected in a combination of horizontal and vertical runs above grade to a terminal connection per illustration. • The above is for work in a single story building, for a floor to ceiling height over 12'0" to 20'0", add 20% to the Manhours shown.

Process and steam piping installed based on using A-53 carbon steel pipe, from 2 to 24" , cost does not include fittings, valves, support devices or erection joint buttwelds, which must be added.All field fabricated and erected. FOB Prices (USD):

  • The pipe prices are for plain end pipe. For threaded and coupled pipe add 30%.
  • The prices do not include fittings, valves or support devices also pipe coating and wrapping which must be added
  • For MH Installation It is assumed “OSBL outside a building-man-hours installation”.
  • For ISBL add 120% on Mhrs. values.
    • For work inside a multistory building with a maximum floor to ceiling height over 12'0" to 20'0", add 20% to the Manhours shown.
    • For work inside an industrial building with unlimited ceiling heights and the piping being installed at various floor and platform levels, add 125% to the Manhours shown for work inside a multistory building.
    • For piping in an open trench Inside Battery Limits of a Process Area installed during foundation construction and before erection of Process Equipment, deduct 50% from Manhours below.
