PA1106 - ASTM A-106 GROOVED END CARBON STEEL PIPING SYSTEMS



The grooved piping system joins together two pipe ends by using a coupling that is seated in grooves at the end of each pipe. When the coupling is assembled, the coupling keys engage the grooves around the circumference of both pipes, providing a secure connection.
There are two types of grooving: roll grooving and cut grooving. Roll grooving uses a special machine that rotates the end of a pipe through a roll set, displacing the metal and forming a groove on the outside surface of the pipe. Roll grooving is limited to use with pipe having a hardness value of HB180 or less. Roll grooving can be accomplished on carbon steel, stainless steel, copper, and aluminum. However, care must be taken to use the proper equipment and roll sets (which may vary with piping material) to create the groove. Consult the grooving machine manual or roll set instructions.
Cut grooving is performed by turning the pipe on a lathe, removing metal from the outside surface of the pipe to create the groove. Cut grooving is intended to be used with Schedule 30 and heavier wall pipe.


TECHNICAL DATA

  • The maximum allowable tolerances for IPS Pipe from square cut ends are:

Sizes

1 to 3 (DN25 to DN80) 0.030 inch (0,76 mm)
Sizes

4 to 6 (DN100 to DN150) 0.045 inch (1,14 mm)
Sizes

8 to 24 (DN200 to DN600) 0.060 inch (1,52 mm)
Sizes

26 to 42 (DN650 to DN1050) 0.125 inch (3,18 mm)

  • Gasket Seating Surface “A” must be free from score marks, ridges, in - dentations, projections, loose paint, scale, dirt chips, grease, and rust that would prevent a positive seal.
  •  Groove Diameter “C” must be uniform depth around the circumference of the pipe.
  •  Groove Depth “D” is a reference dimension of the distance from the pipe outer surface to the groove bottom, with regards to groove concentricity about the pipe. This dimension is a reference only. The actual dimension “C” must be maintained.
  •  Minimum Wall Thickness “T” is the minimum pipe wall thickness that should be roll or cut grooved.
  • Maximum allowable pipe end flare diameter is measured at the pipe end diameter. (Roll Grooved Pipe only)

 



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 26" to 48" , 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.
