Studding Outlets

Page 3: FVC Nozzle 2

42

FVC studding outlets have many advantages whencompared to corresponding ASME B16.5 rated connections:1) a bolted style connection of significantly lower cost2) a lighter-in-weight bolted connection, requiring less material…the savings

in alloy construction are significantly higher3) a compact profile, thus providing lower projections for limited clearance

situations4) integral reinforcement…the outside diameter and/or overall thickness of

FVC studding outlets can be increased to eliminate the need for additionalreinforcement. This one-piece construction simplifies the welding required,thus reducing the cost of welding. Increasing labor costs are becoming amore significant part of finished product costs.

Studding Outlets

Remember, FVC provides custom design service for your special requirements,at no additonal cost. Please call FVC for your studding outlet needs.

Page 4: FVC Nozzle 2

43

There are many options available on FVC studding outlets,some of which include:1) contoured or flat bottoms…FVC can provide any degree of contouring to

suit your special mounting requirements2) air test holes as required by ASME Code…FVC can also provide test holes

to suit special customer requirements3) sight and light glass mounts…FVC can provide special machining of

studding outlets for your sight glass assemblies. A sketch of your individualrequirements is all that is needed.

4) contoured insert lips…FVC can provide contour forged or contourmachined insert lips for Type “Q” attachment as shown in ASME Sec. VIIIDiv. 1 Fig. UW16.1 or Div. 2 Fig. AD 613.1 requirements.

5) increased O.D. or thickness for additional reinforcement6) reduced O.D. or thickness when ASME B16.5 dimensions are not re-

quired… contact FVC to check your savings7) numerous special facings…please specify when ordering

150 FVC Studding Outlets

Material: FVC forged studding outlets are made from SA-105 in compliance with ASME Section II. FVC studding outlets are available inother material compositions upon request. See “Technical Section” on page 59 for stocked materials.

Thickness: The standard thickness shown in charts for all FVC studding outlets is the minimum required per ASME Section VIIIDivision 1 Paragraph UG-43(d) for thread engagement and an l.D. mount (Fig. A, page 50). It is important to note that each individualapplication should be analyzed for proper thickness. See general notes for more details.

Facing: The FVC studding outlet minimum thickness “T” includes proper raised face per ASME B16.5. FVC can supply any specialfacing as needed upon request.

Material: FVC forged studding outlets are made from SA-105 in compliance with ASME Section II. FVC studding outlets are available inother material compositions upon request. See “Technical Section” on page 59 for stocked materials.

Thickness: The standard thickness shown in charts for all FVC studding outlets is the minimum required per ASME Section VIIIDivision 1 Paragraph UG-43(d) for thread engagement and an l.D. mount (Fig. A, page 50). It is important to note that each individualapplication should be analyzed for proper thickness. See general notes for more details.

FVC Studding Outlets

CLASS

2500

Drilling and Tapping: FVC studding outlets are furnished to ASME B16.5 specifications unless otherwise specified. Thread depth is inaccordance with ASME Section VIII Division 1 Para. UG-43(g) for a design temperature not to exceed 650°F, a base metal stress of17,500 psi, and a stud stress of 25,000 psi. All other materials exceeding these stresses should be checked for UG-43 compliance.

Bore: Bore sizes shown above are standard, other sizes can be furnished upon request.

Curving: All FVC connections can be furnished contoured to fit any shell, head or cone at a minimal cost.

General Notes for FVCStandard Studding Outlets

Codes:Material and manufacturing practices for FVC studding outlets are in compli-ance with ASME Section II, Section VIII Division 1, and B16.5. Other re-quirements can be met when specified.

Materials:FVC forged studding outlets are made from SA-105 in compliance withASME Section II. FVC studding outlets are available in other material compo-sitions upon request. See “Technical Section” on page 59 for materialsstocked by FVC.

Thickness:The standard thickness shown in charts for all FVC studding outlets is theminimum required for ASME Section VIII Division 1 for thread engagementand thickness required for mounting the studding outlet to the I.D. as shown inFIG. A. It is important to note that for studding outlets which are set through avessel (FIG. A), the thickness of the studding outlet may need to be increasedto comply with ASME Code, Section VIII Division 1, paragraph UG-43(d)requirements. For studding outlets mounted to the O.D. as shown in FIG. B, areduction of thickness is possible. If the required minimum thickness is greaterthan FVC standard due to the ASME reinforcing requirements, FVC willincrease the studding outlet thickness as necessary at the buyer’s request orwhen design data is supplied with an order. The minimum thickness is mea-sured at the points in FIG. C and FIG. D.

Facings:All FVC studding outlets are furnished with a raised face per ASME B16.5. A0.06-inch raised face is provided on CLASS 150 and 300 flanges. A 0.25-inchraised face is provided on CLASS 400 and above flanges. These facing thick-nesses are included in the “T” dimension. See the “Technical Section” onpages 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 otherwisespecified. See the “Technical Section” on pages 60 and 61 for complete FVCtolerances.

Bore:Standard bores on all FVC studding outlets are to the nominal flange size.Larger or smaller bores can be provided on all FVC studding outlets uponrequest.

Notes continued on the following page.

Underside Curvatures:Unless otherwise specified, all FVC studding outlets will be furnished withflat bottom. Undersides of FVC studding outlets are furnished with a maxi-mum roughness of 500 microinches. This maximum roughness applies tocurved as well as flat bottom studding outlets.

When curving at the underside is required, it will be curved to fit flush on anI.D. mount (FIG. A) at the O.D. perimeter of the studding outlet. Whenmounted to the vessel I.D., some variation from a true radius may occur ontransverse centerline of cylindrical radius. The amount of variance will notexceed the maximum out-of-roundness tolerance per ASME Section VIIIDivision 1 paragraph UG-80. An outside shell mount (FIG. B) must be speci-fied by the customer as it requires special contouring.

When a “Wrap Around” configuration exists and the outside diameter of thestudding outlet exceeds the outside diameter of the shell to which it ismounted, the pad will be square as shown in FIG. E.

FVC studding outlets for hillside, inclined and conical locations will beprovided in the same manner as curvatures. There are no restrictions to theseverity of curvature which FVC can provide. Studding outlets requiring acurvature of less than 0.09 inch will be furnished flat, unless otherwise re-quested by the customer.

Drilling and Tapping:All standard FVC studding outlets are drilled and tapped unless otherwisespecified. The drilling and tapping is furnished in accordance with ASMEB16.5. The depth of tapping is in accordance with ASME Section VIII Divi-sion 1 paragraph UG-43(g). Stud holes will straddle centerlines, unless other-wise specified. Studs, nuts, inserts, and gaskets are not furnished by FVC.

Test Holes:Test holes can be provided on FVC studding outlets upon request. The testhole will be provided per FIG. F unless other specific details are supplied bythe customer with a 1/4” diameter drilling and a 1/8” N.P.T. tapping.

Pressure-Temperature Ratings:All standard FVC studding outlets are furnished in accordance with ASMEB16.5. See the “Technical Section” on pages 68 through 72 for rating chartsand notes regarding allowable design pressures and hydrotest pressures.

Heat Treatment:All standard FVC connections CLASS 400 and above are supplied in thenormalized condition in accordance with the requirements of ASME SectionII. Additional heat treatment requirements can be furnished upon request.

Reinforcement:Particular attention must be paid to the area required for reinforcing an open-ing using a studding outlet because of the voids created by the tapped holes.Paragraph UG-37 of ASME Section VIII Division 1 addresses the planes ofreinforcement and the “F” factor. This reduction of available reinforcementmust not be overlooked. See the following table for area of various tappedholes. The area lost from the tapped holes can be provided by increasing the“T” dimension or the O.D. when required.
