"Established in 1976"
  • Established in 1976
  • Standard line of connections for pressure vessels
  • Custom engineered products
  • Carbon, alloy and stainless steel
  • Complete design, engineering and technical support
  • ISO 9001 certified since 1994

"Forged Connection"
  • Forged Connection
    • Superb Grain Flow
    • Engineered to withstand stresses from bolting and internal pressure
    • Tightly controlled metallurgy, with fine grain practice
  • Fabricated Connection
    • Discontinuity in the grain flow
    • Additional components required
    • Additional procurement and procedures
    • Additional welding
    • Additional testing and verification
5
"Flange and the barrel are..."
  • Flange and the barrel are integral
    • Ready for installation
    • Engineered and manufactured to Code
    • Reduced installation procedures
    • Reduced bill of material for purchasing and traceability
  • Quality by design
    • Consistent ID
    • Integrally self-reinforced
    • Custom sizes and ready-to-weld configurations per customer requirement
    • Instrumentation accessibility
6
"8”"
  • 8” and smaller are manufactured from hot rolled round bars
  • 10” and larger are manufactured from forged steel billets
  • Material is electric steel, fully killed and vacuum degassed
  • continued

Economic benefits forgings
  • Lower overall cost
  • Increased production capacity
  • Reduced inventory cost
  • Reduced QA cost
  • Reduced record keeping
    • one part  – one source  – one MTR
  • Improved vessel appearance
    • no weld/grinding at flange/pipe interface
    • repad often eliminated
13
Simplicity of
long weld necks
  • When using Weld Neck Flanges, one has to select the next larger sized flange. For example: for an 18” Bore size when using a WNF, you must select a 20” WNF.  Whereas when using a LWN for an 18” bore size, you would select an 18” LWN (simple and economical).
  • Since the wall of the Long Weld Neck is invariably thicker than the pipe, a Long Weld Neck can take more pipe stress than a pipe and weld neck flange welded together.
  • Stud, nut & gasket kit costs are more expensive for the larger weld neck type.

FVC engineered
  • Flat bottoms or contoured to cylindrical, spherical, or conical radius
  • FVC’s “Q” type attachments are used wherever full penetration welding with 100% x-ray is required
  • Q Type (Insert Lip Style) per ASME Section V111, DIV. 1, Fig. UW16.1, and DIV. 2, Fig. AD-613.1
  • Hillside/Offset type nozzles

Design flexibility
  • Standard design per Section VIII, Div. I requires 18” I.D. V3 nozzle w/ 48” CYL RAD., 20.826 OAL= $3928 list.
  • By forging with a 17” ID Punch, reinforcement requirements are met most economically.
  • 18” 600# RF V2 x 20.606 OAL w/ 48 CYL.RAD. = $3689 list.

Importance of
  • Often a capacity constraint
  • Hard to recruit and retain top quality welders
  • Value to your company of creating additional welding capacity?
  • Probably greater than just the cost saved
