2 Innovators of the industry Bellows assemblies for safety valves, control valves, and regulators. When you look for a formed bellows which is reliable, has a long life expectancy, and is competitively priced, look to HYSPAN. Rigid quality control, modern facilities, and the fact that all operations are performed in our own plant means that you receive both quality and performance. HYSPAN Series 00 Formed Bellows are manufactured in standard sizes ranging from -inch to 0-feet inside, and for a broad spectrum of, temperature, flexibility, and movement requirements while conveying both corrosive and non-corrosive fluids. These bellows absorb axial extension and compression, parallel offset, angulation, or combinations of motions. But there s more. Our engineering assistance is available to you for your special applications or non-standard sizes. Cryogenic disconnect made from Alloy. Vacuum Applications Series 00 Bellows can be used for high-vacuum applications requiring leakage s less than x 0-0 STD ATM CC/SEC at base of x 0 - TORR. Since most of these applications require extremely flexible bellows, Hyspan recommends materials of 0.00 for inside s (I.D.) up to., 0.00 for I.D. up to.0, and 0.00 for I.D. up to. Any material Thickness can be used which has a maximum (Column on pages -) exceeding PSIG. Type stainless steel is preferred because of its weldability and availability; however, other alloys can be substituted. Bellows assembly designed to absorb expansion of oil. Beryllium Copper The beryllium copper alloys have high thermal and electrical conductivity similar to pure copper. It can be readily joined by resistance and fusion welding, brazing and soldering. The material is nonsparking, nonmagnetic; it has high galling resistance, and maintains its strength and ductility at cryogenic temperatures. Bellows can be used for high-vacuum applications. copyright 00 Hyspan Precision Products, Inc. Printed in the USA

INSIDE BAND OUTSIDE BAND Tabulated tolerance is plus or minus for nominal Multiply or Laminated Bellows Any Standard-size bellows can be fabricated with multiply construction up to four plies of equal. The maximum,, and stability are increased in direct proportion to the of plies, but with the same axial deflection as a single ply. Multiply design permits a lower and a greater cycle life than a single ply configuration for an equivalent. This type of construction is recommended for applications with vibration or rapid cyclic motion because of the inherent damping provided by the relative movement of the plies. Multiply construction in not recommended for vacuum application requiring a mass spectrometer helium leak test because of possible out-gassing from an undetectable leak in an inner ply. Series 00 bellows with standard, Style A, or Style B neck trims can be specified with inside or outside bands which increase the from welding or added reinforcement. The band is approximately. times the bellows. The bands are attached by resistance seam welding for sizes through and by edge welding (GTAW) for larger sizes. Caution: The use of bands is not recommended for vacuum applications requiring a mass spectrometer helium leak test. Series 00

4 Explanation of Tabulated Data All dimensional data is applicable to tabulated single and multiply configurations with standard and optional materials. The tabulated performance parameters are for type stainless steel at room temperature; however, they apply to all austenitic stainless steels with minor variations. Variations for other materials are given for each column explanation. s & Properties The performance data tabulated in Columns through (pages -) was calculated for type stainless steel at 0ºF. These values are a function of the Modulus of Elasticity, strength, and fatigue life. If the service conditions are substantially different or an optional material is used, contact the factory for assistance. Optional materials can be substituted which include but are not limited to alloys 00,, 00,, Cb-0 and C-, Nickel 00, Beryllium Copper and weldable Aluminum alloys. Use of Tabulation The data included in this catalog was computed by generally accepted analytical methods and empirical data derived from tests. This data should be used as a design guide only. Consult the factory if you have an application requiring close control of these values. The following paragraph s refer to the column s of the tabulated data on pages through. Number A four or five digit identifies the nominal size (inside ), and a letter corresponds to the material. In order to fully specify the desired configuration refer to the Ordering Instructions on page. Diameter Nominal of the convolutions and the standard neck trim. Outside Diameter Nominal outside of the convolutions and maximum of Style A neck trim. Area The cross-sectional of the bellows based on the mean of convolutions. This multiplied by the equals the thrust force (Lbs.). Thickness The values tabulated are representative designs for each. Other may be available consult the factory. Convoluted Length These values are established by manufacturing limitations. Substantially longer s must be obtained by splicing two or more elements. Any shorter can be specified refer to the Ordering Instructions on page. Pressure The highest internal or external recommended with a corresponding test of. times this value. This is exclusive of the squirm or instability (Column ). The working for internally pressurized bellows is determined from the tabulated in Column, or the squirm calculated from Column whichever is lowest. For convenience Column and include a test factor of., i.e., a bellows can be pressurized to. times the tabulated in Column without permanent set, and the anticipated squirm is greater than. times the value calculated from Column. The working for internally pressurized bellows which are guided or supported to prevent squirm is determined from Column. The working for externally pressurized bellows is determined from Column squirm or instability does not occur. All bellows d at a (Column ) exceeding psi are satisfactory for Full Vacuum (internal) applications Caution This applies to the sections only and the standard neck trims. Long unsupported neck trims may collapse. Multiply or Laminated Construction multiply the values of Columns and times the of plies. copyright 00 Hyspan Precision Products, Inc. Printed in the USA

5 Squirm or Instability Pressure Internally pressurized bellows are unstable at the critical or squirm. In most instances this condition is characterized by the centerline of individual convolutions deviating from a common centerline analogous to buckling of a long column under compression. This condition occurs when the is long relative to the inside over or. times. There is also a less familiar type of squirm which occurs when the plane of the individual convolutions deviates from parallel planes. Either condition represents a maximum and failure will occur if is increased. The tabulated values (Column ) are the maximum recommended internal to avoid squirm for one inch of. The values are based on a test. times the tabulated. The for other s can be calculated by dividing the tabulated value by the square of the. The Column values do not need to be corrected for other materials which have a modulus of elasticity in the range of 0 x 0 psi. For multiply construction multiply the tabulated value by the of plies. Axial Spring Rate The force (Lbs.) per inch of axial extension or compression resulting from the material and configuration constant is tabulated for one inch of. The for other s is determined by dividing the tabulated values by the. Multiply this value by the of plies for multiply construction. 0 Lateral Spring Rate The force (Lbs.) per inch of the lateral offset resulting from the material and configuration constant is tabulated for one inch of. This movement occurs when the ends remain parallel to each other and perpendicular to the longitudinal centerline, but the centerline displaces laterally. The lateral for bellows other than one inch is calculated by dividing the cube of the. For multiply construction multiply by the of plies. Caution The tabulated values must be multiplied by the 000 except as noted to obtain the true. Bellows Movements Axial Deflection The allowable axial extension or compression for one inch of is tabulated for 000 cycles of movement from the nominal to the tabulated value. The movement for other s are obtained by multiplying by the required. Since these values are determined by the metal fatigue due to the bending stress produced by movement it is unchanged for multiply construction. The tabulated values can be corrected for other s of cycles (at 0ºF.) by applying the following factors: Cycles to Failure Multiply by 00.0,000.0,000.00,000 0., , AXIAL Extension or compression from the manufactured along the longitudinal centerline with ends parallel. LATERAL Displacement perpendicular to the longitudinal centerline with the ends parallel. ANGULAR Rotation of the longitudinal centerline about the perpendicular axis. COMBINED Axial, lateral, and angular movements can be combined within the d movements. TORSION OR TWISTING AROUND THE CENTERLINE (Not recommended.) Series 00
