This wouldbe the first of its kind at a BPE meeting.The presentation, given by Dr. Barbara Henon,was not listed on the formal 4-day agenda for thissession of the BPE. A notification had insteadbeen emailed out to all those attending themeeting in San Diego. But I was actually madeaware of the presentation by Barbara.We have, over the years, become good friends.Having worked together on articles related to thebioprocessing industry, as well as various TaskGroups associated with both the BPE Standardand the B31.3 Process Piping code.June 2019 – Vol. 1 Issue 3academic peers. Why? Not because of her lackof understanding or unwillingness to work hard,but because of her gender.After reading and hearing Barbara’s presentationmy level of respect for, not only her intractableknowledge in the art of welding, but her tenacityas well, went into the stratosphere.And I think this speaks to the spirit of manywomen with whom I have worked with over theyears in this industry. Women who have reachedmanagement level positions through hard workand perseverance.One of Barbara’s jobs years ago, was in trainingwelders on how to set up and use the orbitalwelding machines the company she worked formade. She would travel the globe training thesewelders on-site or in their own fab shops.As it turns out she got a great deal of respectfrom these blue collar welders, but managementpersonnel, for the most part, was a differentstory. You might think just the opposite was true,but the reality is that the old 50’s style genderadversity is still lurking within the deep recessesof our population and our industry.Having known Barbara for a number years I havegreat respect for her both personally andprofessionally. After reading through herpresentation, then hearing her give thatpresentation I was humbled by its content.Which brings me to our lead story this month.The ASME BPE Women’s Initiative is a group ofwomen that have coalesced over a commongoal. A goal in which their purpose is to get morewomen involved in working on the ASME BPEStandard.Learning of the obstacles that she had toovercome in acquiring her PhD was enlighteningto say the least. And these obstacles were notlearning related, but rather foisted upon her byWriting codes and standards, like the BPE,allows you to be a part of something that effectscountries around the world. Making the world asafer place. And now to the Women’s Initiative. 1
W. M. Huitt Co.ASME BPE WOMEN’S INITIATIVEby Milena McFeetersJune 2019 – Vol. 1 Issue 3 To promote leadership roles for women inthe bioprocessing industry.During the January 2018 ASME BPE meeting inCape Coral, FL, a group of twelve womenattending the meeting got together for a casualdinner. There was much animated discussionthroughout the dinner out of which it was decidedto found a group that would promote andincentivize the participation of women within theBPE Standards Committee.Why is this needed? According to the MassBioand Liftstream gender diversity report (2016),around 50% of entry level positions in theindustry are filled by women. However, womenonly make up 20% of leadership teams (C-suite),and 10% of Board memberships. A similarscenario plays out at BPE, where women onlymake up 5.7% of voting seats.Since that time, the inaugural group of twelvelike-minded women has grown to twenty-fourparticipants. It was decided at the onset to holdan event at each ASME BPE meeting. Theseevents, for the Women’s Initiative, includenetworking activities and presentations on thetopic of gender diversity from members of theWomen’s Initiative and guest speakers.The reason there are so few women involved inBPE is not because there are few women in theindustry (as the MassBio report clearly indicates)and it is not due to lack of interest or ambition. Asthe report also shows, when it comes toaspirations, both women and men have similarambitions to serve in the C-suite and oncompany boards. The same can be said for thedesire to participate in the development of codesand standards, hoping to become importantcontributors with the capacity to influence andimprove industry practices. The group’s goal is tohelp overcome the obstacles that may deterwomen from attending and becoming votingmembers at BPE, by taking actions such as:The ASME BPE group’s mission is to establish afar-reaching network that can reach out towomen of the bioprocessing industry toencourage and enable participation by womenthat are involved in the various aspects ofbioprocessing related businesses. Businessessuch as chemical processing, parts andequipment manufacturing, engineering, andconstruction. The hope is to generate an interestfor women to become more involved in thedevelopment of industry codes and standards, agoverning factor of industry, instilling safety andintegrity into the construction of bioprocessingfacilities. This, in an attempt to help steer thefuture of codes and standards development bybringing a more balanced gender representationto those writing such codes and standards.Focus of the Women’s Initiative is to reflect thesame gender ratio in the BPE as that of theactual percentage of women employed in thebioprocess industry.The main objectives of the Women’s Initiativeare: To increase participation by, andmembership of, women in the ASMEBPE Committees. Mentoring new and existing femalemembersEncouraging employers to supportfemale participation in StandardscommitteesEncourage female members to volunteerfor leadership rolesImprove value gender diversityThe presentations organized by the Women’sInitiative are open to the public. Dr. BarbaraHenon, past Vice Chair of ASME BPE, during theMay 2018 BPE meeting in San Diego, CApresented her personal story of discriminationand discouragement that began back in the1950’s and continued throughout many decades.The men who attended the presentation, menwho have known and respected Barbara foryears, were unaware of the difficulties sheexperienced early in her career, difficulties basedpurely and solely on her gender. Her hard work2
W. M. Huitt Co.June 2019 – Vol. 1 Issue 3break in the meeting, I made myway to the ladies restroom (wherethere was no line, due simply to thefact that few women were inattendance) when this very nicelady from Italy caught me in thehallway and approached me. Shevigorously shook my hand, all thewhile telling me how wonderful itwas to meet me, the only woman,sitting at the table with all thosemen. Not until that moment had Irealized that I was, indeed, theonly woman at that table. I find itsomehow odd, and perhaps a littlediscerning that it was not apparentto me before.and determination at times went largelyunrewarded, and at other times simply ignored.Above is a photo of Barbara receiving a standing“O” after her 2018 presentation In San Diego.At the last ASME BPE meeting in Portland, ORIndu Conley presented a summary of the findingsof the MassBio report that provided those inattendance with the facts related to gender diversityinthebioprocessing industry. Suchtimelyandinterestingpresentations help bringawareness to the entireindustry. The photo shownon the right was taken at thedinner meeting held inPortland.Some years back, at one ofthe ASME BPE StandardsCommittee meetings, onlyone woman, myself, MilenaMcFeeters, was seated at‘the big table’. The tablewhere all of the votingcommittee members areseated and report on theweeks activities. During a I suppose you could say that this is the world welive in. But should it be? Currently the perceptionof a few women seated at the committee table isthe norm. Our mission, as the Women’s Initiative,is to change that perception into it being anexception not to have more women seated at thetable. Even if it means longer lines at the ladiesbathroom! Something we have all learned to livewith. Edited by W. M. (Bill) Huitt3

Initially designedand marketed for the food and dairy industry bythe Tri-Clove corp. it is made up of four differentcomponents: 2 Mating FerrulesCircumferential ClampBolt or BoltsGasketThis design provided for easy assembly anddisassembly. A necessity for the food & dairyindustry for cleaning piping systems betweencampaigns. This was prior to the concept ofintegrating Clean in Place (CIP) systems like wecurrently do today to a large degree.In the 1980’s, when the pharmaceutical industrybegan moving from glass tubing and glass-linedpipe and equipment to stainless steel, they toowere looking for a system that was easy toassemble and disassemble, for much the samereason as the food & dairy industry.The tubing components used in the food & dairyindustry, like the clamp assembly, were referredto as sanitary fittings, and still are. But the tubingfittings for the pharmaceutical industry, whileinitially referred to as “sanitary” fittings evolvedinto a higher expectation of cleanliness bychanging the term to “hygienic” fittings. Theseclamp assemblies, for a number of years afterbeing adopted by the pharmaceutical industry,continued to be referred to as the Tri-Clamp joint.So named by the Tri-Clover Corp.Problem was, there was no standardization ofthe clamps, the ferrules, the tees or even theelbows, which were referred to as long tangentelbows at the time.4
W. M. Huitt Co.June 2019 – Vol. 1 Issue 3The finer points of the BPE clamp assemblycomponents can be described in the followingmanner:2 Mating FerrulesIn looking at the ferrule and its relative attributesto the assembly there are two Types found in theBPE standard, Types A & B (Ref. Figure 1). TypeA applies to ferrules in sizes 1” and smaller. TypeB ferrules apply to sizes 1” and larger.The 1” size overlap of the two Types is due to aleak integrity issue years ago having to do withthe 1” Type B ferrule; the specifics of which arenot relative to this subject matter and will not bedescribed in this column.As shown in Figure 1 the 1” and smaller Type Aferrules have a different gasket seat design thanthe 1” and larger Type B ferrules as also reflectedin Figure 1. Since the 2009 edition of the BPEStandard there has been a choice of the twoTypes of sealing surfaces for the 1” ferrules.Figures 2 and 3 represent a segment of theclamp joint assembly consisting of the clamp, 2ferrules (welded to tubing), and a gasket. InFigure 2 there are three forces working on thisassembly. They include: 1. Hydrostatic EndForce, which is pressure of a confined fluid actingin parallel to the pipe axis to oppose the sealingforce at the ferrule face. 2. Internal Pressure,which is the force acting at right angles to thepipe axis attempting to overcome confinement.3. Gasket Load, which is a function of the forcecreated when clamp draw-down forces theferrules to compress the gasket enabling thesealing surface to withstand internal fluidpressure.Figure 2 – Forces Acting For and Against ContainmentType A FerruleType B FerruleFigure 1 – ASME BPE FerrulesIn Figure 3 there are two forces at work. Theyinclude: 1. Clamp Draw-Down Force, which isthe force applied to the assembled ferrulesthrough the act of drawing down the clamp overthe ferrules with a bolt or bolts. 2. FerruleSecondary Reaction Force, which are deflectiveopposing forces created by drawing down theclamp creating a pre-load on the gasket.Figure 3 – Forces Acting To Seal the JointAs seen in Figures 2 and 3 the two ferrules in thehygienic clamp joint assembly provide theassembly’s sealing surfaces, which requires apliable material between the two surfaces in theform of a gasket. Gaskets and their material willbe discussed later. But in order to pre-load thegasket between the two ferrules a clamp with aconcaved wedge pattern is forced down over thetwo ferrules creating a draw-down force. Thisperipheral force, achieved in large part toresistance from the highly rigid form of the roundtubular ferrule, is applied to the backs of the twoferrule flanges creating opposing deflective or5

SG-4.2 and Fig. SG-4.2-1.The re-directed force against the gasketbecomes the preload force and has to besufficient enough to contain the internal fluidpressure plus the hydraulic end force pressureattempting to separate the two ferrules.For metallic ferrules and clamps, temperaturedoes not become a factor in load calculationsuntil it becomes elevated enough to begindepreciating the allowable stress value (Sa) ofthe metal. For 316 and 316L that temperature is399 F (203 C). At 400 F (204 C) and above theallowable stress of this austenitic stainless steelthen begins to depreciate making it, at thoseelevated temperatures, an essential factor inload calculations.BoltsFigure 4 – 3-Piece Double Pin Clamp Joint AssemblyThere are two general types of hygienic clamps,those that are hinged and secured to the ferruleand gasket assembly with a single bolt and wingnut (Fig. 4), and those that are made up of twoseparate pieces forming a peripheral clamp andsecured to the ferrule and gasket assembly withtwo bolts and nuts (Fig. 5).When assembling a hygienic clamp joint unionmuch of its theoretical sealing integrity is basedon a pre-determined torque value used infastening the bolts. Sealing integrity refers to theability of the gasket and ferrules to seal againstthe internal fluid pressure while not exceedingthe intrusion/concavity tolerances specified inFigure 5 – 2-Bolt High Pressure Clamp Joint AssemblyIn taking a page from the Machinery’s Handbookit states that, “Laboratory tests have shown thatwhereas a satisfactory torque tensionrelationship can be established for a given set ofconditions, a change of any of the variables, suchas fastener material, surface finish, and thepresence or absence of lubrication, may severelyalter the relationship. Because most of theapplied torque is absorbed in intermediatefriction, a change in the surface roughness of thebearing surfaces or a change in the lubricationwill drastically affect the friction and thus thetorque tension relationship.”In a paraphrased statement found in FederalStandard FED-STD-H28A it elaborates on theprevious statement by further stating that, “Thus,it must be recognized that a given torque will notalways produce a definite stress in the bolt butwill probably induce a stress that lies in a stressrange that is satisfactory.”These statements go to the heart of the fact thatusing a torque value to pre-load a hygienic clampjoint assembly is not a truly accurate mechanismfor gauging load on a sealing surface, but willinstead achieve a load value approximate to apredetermined target value. And then, only if thebolt(s) are properly lubricated.When tightening a bolt in order to seal an ASMEB16.5 flange joint or an ASME BPE hygienic6
W. M. Huitt Co.clamp joint the installer is attempting to applytension to the bolt or bolts used to create thesealing load. There is a direct correlationbetween bolt tension and the amount of loadplaced on the affected sealing surfaces whetherit is a flange joint or a hygienic clamp joint. Bolttension is directly related to the amount ofcompressive force that is applied to the gasket.That tension, while in the bolt’s elastic range,creates a live load on the sealing surfaces whichallows the joint to remain sealed throughoutfluctuations of thermal cycles and transientdynamic surges; unless, that is, bolt tensionrelaxes due to gasket creep, or bolt stressexceeds the material’s elastic range.And even though gauging bolt stress may be amore accurate approach in determining gasketload, in field installations this is not oftenpractical. To use such sophisticated and costlyinstrumentation as an ultrasonic stress analyzerto detect bolt tension when tightening bolts,thousands of bolts in many cases, cost andschedule make this method prohibitive. It isinstead much more economical and practical toset a torque value and then use a torque wrenchto meet that compressive load target value.In using torque values as a target value thegasket manufacturer has to first of all set a torquevalue that establishes the needed load or forcerequired in tightening the nuts and bolts in orderto achieve the gasket compression necessary toseal the joint. That pre-determined torque valueis then achieved during installation with the useof a torque wrench. But this, even though a muchmore practical method, can be flawed if not doneproperly.The torque wrench measures and quantifies theenergy required to tighten a nut to apredetermined torque value, which is given in inlb or ft-lb values. Therefore the measurement oftorque is an indication of the force applied at thenut, which does not necessarily translate into theforce or compression load realized at the gasket.Nor is it a direct correlation with bolt tensionvalues as mentioned previously.June 2019 – Vol. 1 Issue 3In order for torque values to work properly for agiven application those values have to be predetermined through testing and qualifying by, inthis case, the gasket manufacturer or a qualifiedthird-party tester. However, the inherent problemwith using torque values is that it is, asmentioned earlier, an indirect and somewhatinaccurate method of measuring bolt tension,which is, as also mentioned, the less direct valueassociated with gasket compression.The problem is that when assembling possiblythousands of mechanical joints in the field it isvery inefficient to gage bolt tension on thousandsof bolts. By therefore being relegated to using atorque wrench against pre-determined torquevalues the process then becomes dependent, inlarge measure, upon replicating the method usedinitially to determine the proper pre-establishedtorque values that will achieve the necessarygasket compression.What occurs in the process of assembling aclamp joint is this: in tightening bolts there can beconsiderable variation and opportunity for loss intorque, or quantified force in the contact pointsbetween the bolt head, where the torquemeasurement is taken, and the gasket where theforce is needed.This is due to what is referred to as a “non-linearvariation” caused by friction loss that occurs atthe points between the bolt head (torquereading) and the gasket surface.The loss in force is due mainly to friction createdat two points: The face of the nut against theshoulder of the clamp lug (engagement contactpoint 1 Figures 4 & 5) where as much as 50% ormore of the torque value can be lost; and also atthe engagement threads (engagement contactpoint 2 Figures 4 &
