INTRODUCTION

Bolted Flanged Joint Design Flanges are installed in piping systems for ready removal of piping to provide for portability of machinery and equipment, to facilitate inspection and cleaning, and to avoid in-position welding or heat treatment. The bolted flanged joint is a common structure. Its component members must be affordable to manufacture and install. Component selection principles must be simple and straightforward so that the working engineer can apply them across a wide variety of operating conditions. Bolted flanged joints should be kept at a minimum for operating and maintenance conditions and, insofar as possible, located in the most advantageous position with respect to applied moments. They must be designed to withstand the longitudinal forces and bending of torsional moments due to weight, thermal expansion, and shock to which they will be subjected, and to maintain a tight joint. Bolts should be pre-tightened to a proper preload. Standard flange types are contained in American National Standards Institute (ANSI) Standard B16.5, Steel Pipe Flanges, Flanged Valves and Fittings. The selection of B16 standard flange components is an easy process. Simply follow the rules found in ASME B31 Piping Code. ASME component materials are designed to be safe and reliable. For further reading about flange design see: M. W. Kellogg Company, Design of Piping Systems , Martino Publishing, 1941,1956 reprinted 2009.

be adequate to resist all conditions that tend to produce a leaking or ruptured joint. Therefore, it is necessary that F i be accurate and as high as possible, but within proper limits. If F i is excessive, yielding of the flanges and/or fasteners can produce relaxation that might result in a mode of failure. F i is critical for compression type gaskets where the gasket must be seated properly by applying a minimum load in the cold condition while maintaining a minimum unit load over the effective contact area of the gasket under operating conditions. High F i has the added advantage of making the fastener self-locking; an advantage in avoiding fatigue failure. A preloaded joint should meet three requirements: • The bolt must have adequate strength • The joint must demonstrate a separation factor of safety at limit load. This generally means that the joint must not separate at the maximum load to be applied to the joint. • The bolt must have adequate fracture and fatigue life. For further reading about Preload, see Blake, Alexander, What Every Engineer Should Know About Threaded Fasteners , New York, Marcel Dekker, 1986. Standard Component Selection Component selection in ASME B31.9 applications The selection of components, materials, practices and other aspects of piping will be determined in part by applicability to: • Standard B31.9, • Type of fluid being conveyed, • Fluid’s pressure and temperature and, • Piping and flanges selected. Components [bolt, nut, gasket] shall conform to the applicable standards in ASME B31.9, Table 926.1. When using an ASME B16 flange, the bolting and pipe flange gasket rules have precedence within the limits of B31.9. Component selection in ASME B31.1 applications The selection of components, materials, practices and other aspects of piping will be determined in part by the applicability to: • Standard ASME B31.1, • Fluid, pressure and temperature, • Flange selected, • Boundary of the completed boiler unit. Piping beyond the boundary of the complete boiler unit is covered by B31.1, this includes Boiler External Piping, and Non- boiler External Piping. Selection of bolting in Table 112 of the B31.1 Code will be determined by flange selection found in Table 126.1 to include the rules, general notes and notes of Appendix A.

INTRODUCTION

Bolted Flanged Joint Connection Types

Component selection in ASHRAE applications ASHRAE joining methods defer to ASME rules governing piping installation. Pipe Flange Bolting, Facing and Gasket Requirements ASME B31.1 Table 112 contains suggestions for matching flange facings, listed bolting groups, and gasket styles. ASME B16 standard specifications specify the allowance of listed low, intermediate and high strength bolting for given gasket constructions. Using ASME listed Bolting Materials ASME materials are selected for strength and ductile behavior. This is especially true when subject to loads during installation or during the operating condition, or when subjected to elevated temperatures. ASME B31 Piping Code and Boiler and Pressure Vessel Code contain the mandatory rules for selecting bolting materials as well as the definition of a standard and special component. Alloy Steel bolting is selected for strength and ductile behavior at elevated temperature. Austenitic stainless steel bolting is selected for corrosion and or temperature resistance. Mild steel bolting is a special case material. When failure is expected to be caused by rupture rather than excessive plastic deformation, the use of the ultimate tensile strength as a criterion for the allowable stress has justification on the basis that the fatigue limit, which controls failure by rupture, is proportional to the ultimate tensile strength. State adoption of B31 Piping Code can be found at (www. nationalboard.org). A bolting material that is not prohibited does not mean it is allowed. The ASME has a formal process for allowing special components. For further reading about allowable stress design and the history of ASME Piping Code, see: Brownwell, L, Young, E, Process Equipment Design, New York, John Wiley & Sons, 1959. Practical application of ASME Bolting materials When the bolt is tightened , the total preload force resisting pressure is some sum of the total bolting force produced by stretching the bolt plus the flange force produced by compressing the flange. When forces acting to separate the flange are in excess of preload forces, the flange compressive force drops from the preload equation and the bolt is subject to both the internal stress produced by tightening the bolt and external stress produced by pressure. If the bolt is overstressed it should demonstrate ductile behavior. As pressure forces separate the joint a leak will ensue thereby reducing some of the forces on the bolt. The overstressed bolt with ductile behavior may not reach ultimate fracture saving a full on flanged joint blowout. The overstressed bolt demonstrating brittle behavior would be likely to immediately fracture. Blow out would be imminent.

BOLTING

Bolting material ferritic chromium-molybdenum alloy ASTM A193 Grade B7, an ASME listed high strength,quenched and tempered When the flanged joint, an indeterminate structure, is studied in continuum mechanics, higher preloads produced by high strength bolting improve the compatibility of displacements where; members initially connected together remain together. Applying the empirically derived design “m” factor (unit gasket contact-pressure ratio) to the minimum required bolt load formula, as pressure increases the minimum bolt load also increases. Higher bolt loads produce a tighter, more reliable joint. The ‘m’ factor is an incremental bolt load to account for, in part, the inability to describe, as an engineering value, rubber and rubber-like gasket stiffness, the initial preload uncertainty and, the effects of component relaxation magnified as steam pressure/temperature increases. Without gasket stiffness, joint stiffness is unknown. There are fatigue implications when joint stiffness is less than bolt stiffness. ‘m’ factor mitigates this risk. When choosing ASME standard B16 flanges with high “Y’ (1) value gaskets of suitable media and temperature resistance, the strength, ductility, and toughness at elevated temperatures of A193 Grade B7 bolting make them the easiest choice for a leak free joint in steam pressure and other similar molecular weight applications.

Bergh, “Effects of Internal Pressure on Stresses and Strains in Bolted- Flanged Connections” , Reprinted from ASME Transactions, 1951 Saint Ferrer ® A193 Grade B7 Alloy Steel Bolting

BOLTING

Saint Ferrer ® A193 Grade B8 & B8M Class 1 Stainless Steel Bolting Bolting material S30400 & S31600, austenitic stainless steel, ASTM A193 Grade B8 Class 1 & B8M Class 1, respectively, ASME listed low strength, carbide solution treated These bolts are made from UNS–designated S30400 and S31600, respectively, stainless steel that has been carbide solution treated prior to manufacturing. Do not confuse this bolting material with the ubiquitous 304 or 316 stainless steel. The carbide solution treating is performed to prevent grain boundary carbide

precipitation at elevated temperatures. Corrosion resistance is decreased by precipitation of chromium carbides.

At room temperature stainless steel materials exhibit high strains beyond their elastic limit. Class 2 materials are strain hardened to improve strength. The softness of stainless materials subject them to galling.

Code will be determined by flange selection found in Table 126.1 to include the rules, general notes and notes of Appendix A.

Saint Ferrer ® A307 Grade B Low Carbon Steel Bolting Bolting material, low carbon steel, SA A307 Grade B, ASME listed low strength Subject to an initial tension, called preload, into its plastic region, mild steel A307 Grade B bolting satisfies the requirements of ASME standard component allowable design stress (ADS) without the need to offer or have available to the owner substantive proof of special or nonstandard design taking into consideration a comparison that addresses plastic instability (necking) in strain rate dependent materials. When pressure forces exceed preload forces, mild steel bolting may experience a ductile to brittle transformation depending on the strain rate produced by loads, i.e. live, cyclic, or hammer loads; temperature also plays a role. Ductility is an indication of toughness – its ability to absorb work in the plastic region. Ductile bolting failure

would actualize a flange joint leak- relieving pressure – avoiding overstress, fracture propagation, and blow out in other components. Ductile, brittle and tough are not stand-alone terms; they are employed to describe the behavior of one material relative to another. “Stronger” mild steel bolts may be less ductile, more brittle, and less tough than A307 Grade B in pressure vessel applications. An examination of lot specific stress strain curves rather than those produced in standards with an offset yield, as well as Considere’s criterion may further an understanding of plastic instability and the behavioral differences of a mild steel rod in uniaxial tension. A307 Grade B’s maximum UTS and maximum sulfur content control the bolting’s hardness, notch toughness, and fracture propagation. These properties are specific to A307 Grade B bolting

and have merit when used with all B16 flanges; Grade B bolting is not restricted to use only with cast iron flanges. Ultimate tensile strength is a physical term associated with a material’s behavior as observed on the stress-strain curve.

Gasket Information Flange Facing

Bolting Type and Dimension High and intermediate strength bolting should be fully threaded stud bolts measured end-to-end. Low strength bolting should contain heavy hexagon machine bolts manufactured to the dimensional standard ASME B18.2.1. High strength and low strength bolting shall contain heavy hexagon nuts manufactured to the dimensional standard ASME B18.2.2. Heavy patterns promote the cone-like section of the preloaded physical interface and the effective compressive stiffness zone. Washers do not add to the compressive stiffness zone. Bolting shall be marked in accordance with their relevant standard specification. Bolting Thread Fit and Pitch Low strength bolting should be threaded to ASME B1.1 UNC, intermediate and high strength bolting to 8UN. Externally and internally threaded components should have the same thread pitch. For normal service, Thread Class and Fit should be 2A/2B. Thread Fit of internal and external class threads, A and B respectively, may be mixed to develop varying bolting strengths. Interference thread fits cannot be mixed. Thread Protrusion and Engagement Bolting used to join flange joints with through holes are called through bolts. To fully develop bolting strength, only heavy hexagon nuts should be employed with through bolts. Bolting is also used to join flanges to valves with tapped holes. In either occurrence heavy hexagon head machine bolts or fully threaded stud bolts can be employed. In design, it is preferable to encourage the bolt to fracture in tension before the threads fracture in shear. To insure the potential for a fully developed bolting strength, bolting should fully extend beyond the face of a heavy hex nut. To assist inspection and mitigate the negative effects of corrosion, bolting should have no less than one, and no more than three full thread(s) of protrusion. In tapped holes, it is desirable that the internally threaded material be harder than the externally threaded bolt. The hardness of bolting relative to its mating threaded component may require a calculation to determine the length of thread engagement that will fully develop bolting strength. In normal service, bolting shall have a minimum thread engagement equal to at least one times its diameter. Excessive forces caused by bottoming out the bolt in tapped holes could cause cracks in sections of the material.

Flanges using non-metallic, ASME Group 1a, elastomer and compressed fiber gaskets 0.062-inches thick perform best when they are mated to a contact surface of 500 to 1000 Ra circular lay finishes, or 125 to 500 Ra spiral lay finish produced by machining 30 to 80 serrations of uniform depth per inch of face width. Flanges having a nominal pipe size (NPS) greater than 12 (in.), 21 to 80 serrations is permissible. Flanges using metallic spiral wound gaskets perform best when mated to a contact-face circular or spiral lay surface finish of 125 to 250 Ra. The spiral lay finish shall be produced by machining 45 to 55 groves per inch of face width. Raised face flanges should use ring style gaskets. Flat Face flanges should use flat face gaskets. Installation problems, such as excessive flange rotation and overstressing the flange, can be avoided by mating like kind facings, that is, raised face to raised face or flat face to flat face. Gasket Compatibility The gasket should not be injuriously affected by the operating Gasket thickness should be determined by condition of the contact surface. Nonmetallic gaskets should be fabricated in accordance with the requirements of ASME B61.21. Metallic Gaskets shall be manufactured in accordance with the requirements of ASME B16.20. Gasket Groups and Design Constants ASME B16.5, Table B1 groups gasket materials by construction. Group numbers are useful for applying Code bolting rules. ASME B16.5 Figure E-1 contains gasket design constants for gasket material constructions. These constants are useful for the design of a minimum required bolt load in the operating condition and the gasket seating condition. Gasket design constant ‘m’ factor is a gasket factor used as a multiple of pressure to maintain a gasket load during the operating condition. Gasket design constant ‘y’ is the minimum unit area gasket seating load, psi. Bolting Information Bolting Temperature Limits The maximum temperature limits of bolting materials are found in the general notes to bolting specification in Table 1b of the applicable B16 flange standard specification. conditions of media and temperature.
