Seamless Construction
Consider All That is Involved in
Built-Up Construction of Connections:
The large family of FVC standard seamless one-piece
construction connections eliminates the need for you to use a
pipe/flange/reinforcement pad “built-up” construction nozzle.
This removes the fabrication and material traceability problems
which plague fabricators using “built-up” nozzles.
8
Seamless Construction
Then Choose FVC
Evaluate a few of the advantages provided by
FVC integrally reinforced standard connections:
1) Contour forged close to the finished profile for aligned grain flow of
material, resulting in maximum strength and toughness.
2) Less possibility of distortion from heat of welding.
3) Reduction of total time required for vessel fabrication, therefore speeding
up delivery and cash flow of each job.
4) Easier traceability of material, only one piece vs. two or more pieces
required for “built-up” construction — many times test certificates can be a
large additional hidden cost.
5) “Ready to install” convenience.
6) Larger manway bore diameters — when a 16-inch I.D. is required you only
pay for a 16-inch FVC nozzle and 16-inch mating components, but if you
use a “built-up” construction you pay for an 18-inch weld neck flange, 18inch pipe and an 18-inch blind. Therefore you save by not paying for the
larger blind flange gasket as well as the larger or more nuts and studs
associated with “built-up” nozzles, For larger minimum I.D.’s the savings
become even greater.
7) Integral reinforcement lowers overall fabrication cost by reducing or eliminating the cost in the following areas:
(A) Purchasing and Expediting: One part vs. pipe, flange, and plate.
(B) Material Handling: One piece to unload, stock, and move to shop for
final installation.
(C) Inventory Control: Fewer parts to stock, trace, and locate on plant site.
(D) Production Scheduling: FVC Seamless Schedule System of “Reduce &
Eliminate” saves time and money…

(E) Quality Control: Time spent verifying all the material certifications,
testing procedures, vendor compliance, accompanying customer inspectors witnessing testing and vendor certificates is reduced.
(F) Sales & Marketing: The on-time shipment and the aesthetic appeal of a
vessel fabricated using FVC seamless connections creates an atmosphere which “Reduces” the sales effort required to obtain the next
order from your customer.
Compound these advantages with other disadvantages of “built-up” construction and it is easy to see why FVC standard seamless connections should be
used for all of your flanged nozzle requirements.

Seamless Construction
FVC Offers Largest Variety of
Standard Connections
FVC flanged connections are available in a large variety of standard barrel
thicknesses. These styles include the FVC LWN, the HB, the Variable Body
Connections Vl, V2 and V3 and the F connections. This wide variety of standard barrel thicknesses was developed in order to provide a FVC standard
product that fulfills your individual reinforcement applications. All FVC
standard flanged connections are:
1) Seamless forged construction.
2) Manufactured in strict accordance with ASME Sec. VIII, Div. 1.
3) Manufactured in all of the sizes and pressure classes covered by
ASME B16.5.
4) Manufactured and stocked in SA-105, SA-350-LF2, SA-182-F1,
SA-182-F11, SA-182-F304(L), and SA-182-F316(L).
Other materials can be provided, see page 59.
The following describes the variety of standard connections offered
by FVC, progressing from the thinnest standard neck to the thickest standard
connection:
The FVC Type “LWN” — “Long Welding Neck”
The “LWN” is FVC’s basic standard flanged connection. This seamless product offers a nominal bore as well as a heavy wall thickness, making it ideal for
highly corrosive applications.
The FVC Type “HB” Neck — “Heavy Barrel”
The “HB” neck furnishes more integral reinforcement than the corresponding
size FVC “LWN” which is accomplished with a thicker barrel neck section.
There are additional features on this style neck:
1) On FVC “HB” necks an automatic “nut stop” is provided by the
standard barrel O.D. This eliminates the need for a second holding
wrench. An optional “nut relief” in the barrel will allow two wrench
operation.
2) FVC “HB” necks, sizes 12 inch and below are furnished with Sch 80
bores. Manway sizes 14 inch and above have bores equal to the
nominal size.
The FVC Type “F” Nozzle — “Full Body”
The FVC Type “F” body connection provides the most reinforcement among
the standard connections. The barrel O.D. is the same as the flange O.D.
10
Seamless Construction
Variable Body Connections
The FVC Type “V” Nozzle — “Variable Body”
Never before has a manufacturer offered so many standard barrel thicknesses
in seamless connections. This variety enables FVC to provide a sufficient
amount of integral reinforcement required while keeping nozzle weight and
cost down to a minimum. Don’t compromise with an expensive “custom”
forging when you can find the required barrel diameter in the standard FVC
“Variable Body” charts on the following pages. The FVC “Variable Body”
connections provide more integral reinforcement than an “HB” neck, without
the added cost of a custom forging or the added cost and weight of an “F”
connection.
Optional Features
All FVC connections are available with the following optional features:
1) contoured bottoms: “cylindrical”, “spherical,” or “hillside”.
2) special lengths, longer or shorter than the standard lengths listed in the
price list are no problem for FVC.
3) insert lips, contour forged or contour machined.
4) additional facings, standard B16.5 or custom designs.
5) “nut stop” barrel, (except on LWN’S).
6) optional Barrel O.D. and I.D.
7) FVC can also make LWNs, HBs, Variable Body Nozzles, and F Nozzles
to ASME B16.47 Series A and Series B.
Don’t Compromise
If your reinforcement requirements cannot be met with these standard FVC
products, please see the “Custom Products” section, pages 53-56, for
additional FVC special capabilities.

Codes:
Material and manufacturing practices for FVC connections are in compliance
with ASME Section II, Section VIII Division 1, ASME B16.5, ASME B31.3,
and ASME B31.4. Other requirements can be met when specified.
Materials:
FVC forged connections are made from SA-105 in compliance with ASME
Section II. FVC connections are available in other material compositions upon
request. See the “Technical Section” on page 59 for materials stocked by FVC.
Lengths:
The length of all connections includes the barrel, flange and facing. See the
current FVC price sheet for standard lengths. Intermediate lengths and lengths
longer than standard are available upon request.
Facings:
All FVC flanges are furnished with a raised face per ASME B16.5. A 0.06inch raised face is provided on CLASS 150 and 300 flanges and it is included
in the “T” dimension. A 0.25-inch raised face is provided on CLASS 400 and
above flanges and it is excluded from the “T” dimension. See the “Technical
Section,” pages 62 through 65, for other types of facings available on FVC
flanges. Gaskets are not furnished by FVC.
Bolting and
Tolerances:
FVC flanges are furnished to ASME B16.5 specifications unless otherwise
specified. See the “Technical Section,” pages 60 and 61, for complete FVC
tolerances. Bolting is not furnished by FVC.
Nut Relief:
All FVC connections, except standard LWN’s, will be supplied with a “nut
stop O.D.” unless a “nut relief O.D.” is specified.
Nut Stop:
All FVC “HB”, “V1”, “V2”, “V3” and “F” style connections are furnished with
“nut stop O.D.” (not available on “LWN” barrels). This barrel O.D. acts as an
automatic nut stop, preventing the nut from turning, thus only requiring one
wrench to loosen or tighten bolting on the connecting pipe side.
Bore:
Standard bores on all FVC connections are to the nominal flange size except
for 12" and smaller “HB” and “Variable Body” connections which are bored
to match schedule 80 pipe. Larger or smaller bores can be provided on all
FVC connections upon request.
Underside
Curvatures:
All FVC connections can be furnished contoured to fit any shell, head or cone
at a minimal cost. Unless otherwise specified, all connections will be furnished with flat bottom.
Flanges and Drilling:
All flanges are drilled unless otherwise specified. Bolt holes are drilled 1/8”
larger than bolts. Bolt holes will straddle natural centerlines, unless otherwise
specified. Bolts, nuts, studs, inserts and gaskets are not furnished by FVC.
Press-Temp Ratings:
All FVC flanges are furnished to conform to ASME B16.5 pressure-temperature ratings. See the “Technical Section,” pages 68 through 72, for rating
charts and notes regarding allowable design pressures and hydrotest pressures.
Heat Treatment:
All standard FVC connections over CLASS 300 rating and CLASS 300 “HB”,
“V1”, “V2”, “V3” and “F” connections are supplied in the normalized condition. Additional heat treating requirements can be furnished upon request.
