TITLE
[0001] Housing for a flow conditioner
FIELD
[0002] A housing for a flow conditioner.
BACKGROUND
[0003] The two common methods of mounting a flow conditioner in a pipeline
include
inserting set screws through the pipeline to engage the flow conditioner, or
to provide a
conditioner with a flange that is held between two abutting pipeline segments.

SUMMARY
[0004] There is provided a housing for a flow conditioner. The flow
conditioner
comprises a circular plate having an outer perimeter and flow conditioning
apertures. The
housing comprises a body having a first pipe connection, a second pipe
connection, a flow
passage between the first and second pipe connections, a carrier receiving
cavity within the
flow passage, and an opening corresponding to the carrier receiving cavity .
The carrier
receiving cavity has a larger diameter than the flow passage. A plate carrier
has a sealing
portion and a flow conditioner carrying portion. The sealing portion has a
sealing surface for
sealing the opening corresponding to the carrier receiving cavity , and the
flow conditioner
carrying portion depends from the sealing portion. The flow conditioner
carrying portion is
sized to be inserted through the opening and into the carrier receiving
cavity. The flow
conditioner carrying portion has an inner surface for carrying the flow
conditioner and an
outer surface, the inner surface being substantially the same size as the flow
passage. The
flow conditioner carrying portion has a plurality of set screw receiving
apertures extending
from the outer surface to the inner surface for adjusting the position of the
flow conditioner
within the inner surface. There is a connector for securing the plate carrier
within the body
such that the sealing surface seals against the body.

[0005] Alternatively, instead of set screw apertures, the flow conditioner
carrying portion
may have a retaining lip extending inward from the inner surface for securing
the flow
conditioner on a downstream side against pressure from an upstream side, the
inner surface
being sized to friction fit the flow conditioner.

DETAILED DESCRIPTION
[0007] A housing for a flow conditioner generally identified by reference
numeral 10 will
now be described with reference to FIG. 1 through 8.

[0008] Structure and Relationship of Parts:
[0009] Referring to FIG. 1, housing 10 for flow conditioner 12 is shown. Flow
conditioner 12 has a circular plate 14 having an outer perimeter 16 and flow
conditioning
apertures 18. Referring to FIG. 2, a body 20 of housing 10 has a first pipe
connection 22, a
second pipe connection 24 and a flow passage 26 between first and second pipe
connections
22 and 24. As depicted, first and second pipe connections 22 and 24 are
designed to be
attached to pipe sections by welding. However, it will be understood that
connections 22 and
24 could also be designed for other types of connections, such as threaded,
flanged, etc. as is
known in the industry. There is a carrier receiving cavity 28 within flow
passage 26, and an
opening 30 corresponding to carrier receiving cavity 28. As can be seen,
carrier receiving

cavity 28 has a larger diameter than flow passage 26. A pipe plug 32 is
located at the bottom
of carrier receiving cavity 28 to allow for cleanout, and to assist in
installing and removing
flow conditioner 12.

[0010] Referring to FIG. 1, a plate carrier 34 is used to hold flow
conditioner 12. Plate
carrier 34 has a sealing portion 36 and a flow conditioner carrying portion
38. Referring to
FIG. 5, sealing portion 36 has a sealing surface 40, which includes a seal 42,
for sealing
opening 30 that corresponding to carrier receiving cavity 28. Opening 30 can
be seen in FIG.
4. Referring to FIG. 2, sealing portion 36 is secured in place over opening 30
by using
connector, in this case, a clamp bar 44. Clamp bar 44 is inserted into a slot
46 in body 20, and
threaded pins 48 are inserted through holes 50 to apply downward pressure on
sealing portion
36 to secure plate carrier 34 within body 12 such that sealing surface 40
seals against body 20.
A top view of clamp bar 44 is shown in FIG. 7.

[0011] Referring to FIG. 1, flow conditioner carrying portion 38 depends from
sealing
portion 36. In the depicted embodiment, sealing portion 36 and flow
conditioner carrying
portion 38 are attached by screws 52. These portions may be otherwise
connected together,
or integrally formed. As will be seen below, a removable connection allows
easier access to
set screws 60, which are used to position flow conditioner 60. Referring to
FIG. 1 and 3, flow
conditioner carrying portion 38 is sized to be inserted through opening 30 and
into carrier
receiving cavity 28. Referring to FIG. 7 and 8, flow conditioner carrying
portion 38 has an
inner surface 54 for carrying flow conditioner 12 (as shown in FIG. 1) and an
outer surface
56. Inner surface 54 is designed to be substantially the same size as flow
passage 26 shown in
FIG. 4. Flow conditioner carrying portion 38 has a plurality of set screw
receiving apertures
58 extending from outer surface 56 to inner surface 54. Referring to FIG. 1,
this allows set
screws 60 to be inserted that can then be used to secure the position of flow
conditioner 12
within inner surface 54, and also center flow conditioner 12 relative to flow
passage 26.
Preferably, there are four set screw apertures 58 and screws 60, which allows
the position to
be easily adjusted vertically and horizontally, although this may also be
accomplished using
three apertures 58 and screws 60. Flow conditioner 12 preferably has small
recesses 62 that
correspond to set screws 60 that allow flow conditioner 12 to be gripped by
screws 60 against

fluid pressure along flow passage 26. Body 20 has machined tabs 64 in opening
30 that
maintain the horizontal position of flow conditioner 12 by holding the top of
flow conditioner
carrying portion 38.

[0012] Operation:
[0013] Referring to FIG. 3, body 20 is installed in a pipeline, generally
upstream of a
flow meter, by connecting first and second pipe connections 22 and 24 in a
pipeline. As
shown, connections 22 and 24 are designed to be welded, but may be designed
with threaded
or flanged connections. Once welded at connections 22 and 24, the only
possibility for
leakage is through opening 38, as body 20 is otherwise solid and closed.
Referring to FIG. 1,
plate carrier 34 is assembled by inserting flow conditioner 12 within flow
conditioner
carrying portion 38 and secured and centered by set screws 60. Flow
conditioner carrying
portion 38 is then attached to sealing portion 36. Once assembled, plate
carrier 34 is inserted
through opening 30 into cavity 28. Clamp bar 44 is slid into slot 46, and
threaded pins 48 are
insered to apply pressure to sealing portion 36 such that opening 30 is sealed
and plate carrier
34 is secured in place. As depicted, vertical position is maintained by the
contact between the
sealing surface 40 of sealing portion 36 and opening 30 of body 20. The
horizontal position is
maintained by the contact of the machined tabs 64 in opening 30 against the
top of flow
conditioner carrying portion 38.
[0014] Plate carrier 34 is removed for servicing or inspection by removing
clamp bar 44.
The depicted design allows a user to reposition flow conditioner carrying
portion 38 each
time it is removed, such that, once properly set, flow conditioner 12 will
remain in the same
position despite plate carrier 34 being removed and replaced.
[0015] Variations:
[0016] As an alternative to set screws 60, referring to FIG. 9, flow
conditioner carrying
portion 38 may be designed to have a closer fit, such that flow conditioner 12
is held in a
friction fit arrangement. In addition, a flange 66 may be provided on the
downstream side to
prevent flow conditioner 12 from becoming dislodged due to fluid pressure.


CA 02675542 2009-08-19

[0017] Referring to FIG. 10, a further alternative may have flow conditioner
12 integrally
formed with plate carrier 34. In this embodiment, flow conditioner carrier
portion 38 is
replaced with flow conditioner portion 68, with flow conditioning apertures 18
positioned
within portion 68 to properly align within flow passage 26 (shown in FIG. 4).
