AMERICAN BOA, INC. TANDARD INDUTRIA EXPANION JOINT ERIE Applications American BOA metal bellows are known for their superior flexibility. The bellows are able to compensate for large movements in the axial, lateral and angular direction or mechanical vibration. BOA bellows ensure the lowest possible forces combined with extreme longevity. This makes American BOA expansion joints and compensators ideal components that minimize stress and strain in pipes and extend the life of any system (steam, hot water, hot gas) exposed to elevated and varying temperatures. American BOA flexible Bellows Connectors ensure that suction and discharge nozzles of pumps and compressors are protected from high forces and moments and that vibration is not transmitted into the piping system. This will increase the durability of rotary equipment and reduce the noise level throughout the entire system. XP Expansion Compensators Compensators are used to absorb thermal growth of small diameter piping systems. By utilizing the externally pressurized bellows design, XP expansion compensators allow relatively large axial movements while maintaining high pressure capacity. XP expansion compensators are available in diameters from 3 through with welding ends or male NPTs in carbon steel and from 3 through 3 with copper ends. The shroud protects the bellows from external damage. This design offers an excellent solution to handle thermal growth of pipes in hot and chilled water, steam and condensate systems in buildings. ECO Externally Pressurized Expansion Joints Externally pressurized expansion joints are designed to compensate for the axial movements of long pipe runs. Available in diameters from 2 through 12 with welding ends or flanges, these standard expansion joints are rated for psig with and axial movement respectively. The heavy housing completely encloses the flexible bellows and provides utmost safety against external damage. ECO externally pressurized expansion joints are a preferred choice for absorbing thermal growth of long distance heat transfer pipes and similar piping systems. 2

HVAC Expansion Joints HVAC expansion joints are typically utilized to compensate for moderate to large thermal expansion in the axial, lateral and angular directions. They are available in diameters from 3 through 2, rated for either or psig pressure with two movement ranges. HVAC standard expansion joints with welding ends or flanges offer an economical solution to most 3-D pipe expansion problems. RV Vent Connectors Vent Connectors are engineered to withstand the turbulent and high velocity flow typical for vent lines after pressure relief or safety valves. American BOA RV Vent Connectors utilize multi-ply bellows that ensure large movement capacity with lowest possible forces and moments at the valve and equipment connections. Multi-ply bellows are superior to any other metal bellows design in handling high frequency, flow induced vibration. The standard RV design features a full bore flow that ensures minimum back-pressure and a heavy housing that protects against damage and uncontrolled flow medium discharge. tandard RV Vent Connectors are available in diameters from 1 1 2 through 12 with welding ends or flanges. BCT Bellows Flexible Connectors Bellows Connectors feature multi-ply bellows for superior vibration control, reduction of stress in pipes and equipment, misalignment compensation and reduction of noise. Utilize BCT Bellows Connectors for suction and discharge connections of pumps and compressors to enhance the life expectancy of rotary equipment and piping, to ease installation and to reduce the noise level throughout the piping system. BCT Bellows Connectors are available in diameters from 2 through and are rated for a pressure of psig at 70ºF. The standard design includes lb. flanges and limit rods. 3

AMERICAN BOA, INC. TANDARD INDUTRIA EXPANION JOINT ERIE Technical Information Thermal pipe expansion Thermal pipe expansion is the change in the length of a pipe due to the variation in temperature caused by the process or ambient conditions. To determine the correct thermal expansion, one shall always consider the lowest possible and highest expected temperature. Table 1: Thermal Expansion Coefficient Thermal Expansion [in./100 ft.] Temp. [F] Carbon teel tainless teel Copper -25-0.6-0.9-1.05 0-0. -0.72-0.79 25-0.32-0.6-0.51-0.1-0.21-0.22 70 0.00 0.00 0.00 100 0.22 0.33 0.3 125 0.1 0.61 0.62 0.60 0.9 0.90 175 0.0 1.17 1.77 200 1.00 1.6 1. 1.20 1.7 1.77 2 1.0 2.03 2.05 275 1.61 2.32 2.3 1.2 2.61 2.62 325 2.0 2.91 2.91 3 2.25 3.20 3.19 375 2. 3. 3. 00 2.70 3.0 3. 25 2.93.10.17 3.16.1.7 75 3.39.71.76 0 3.62 5.01 5.06 525 3.6 5.31 6.35 5.11 5.62 5.6 575.35 5.93-600.60 6.2-625.6 6.55-6 5.11 6.7-675 5.37 7.1-700 5.63 7. - 725 5.90 7.2-7 6.16. - 775 6.3.7-00 6.70.0 - Example: Carbon teel Pipe, 125 ft. long owest temperature: -25ºF Max. temperature: 75ºF Total thermal expansion = 1.25 x -0.6 + 1.25 x 3.39 = 5.075 (inches) Axial Movement the difference in the length of a bellows when moved from any given length to a shorter (compression) or longer (extension) length. Compression Extension ateral Movement the relative perpendicular distance between the centerlines of the two ends of a bellows. ometimes referred to as lateral offset, lateral misalignment or lateral shear. Angular Movement the relative angle between the centerlines of the bellows ends. ometimes referred to as angular rotation.

pring Rate The spring rate is the force or moment required to move a bellows in the axial, lateral or angular direction. The data units are specified in pounds/inch for axial and lateral movements and foot-pounds/degree for angular movements. pring Force / Moment The spring force or moment is the force required to move a bellows through the total required axial, lateral or angular movement. Bellows Effective The bellows effective area determines the pressure thrust when a bellows is subjected to pressure. This area is specified in square-inches. Pressure Thrust Pressure thrust is the force that is exerted when a bellows is pressurized. The pressure thrust is the result of the bellows effective area multiplied by the pressure. Always use the maximum possible pressure (typically the test pressure) when determining the pressure thrust. Pressure thrust [lbs.] = bellows effective area [in 2 ] x maximum pressure [lbs./in.] The pressure thrust must be restrained either by means of pipe anchors or by the equipment itself to which the expansion joint or pipe section is attached. If this cannot be achieved or proves expensive, the pressure thrust must be restrained by suitable expansion joint hardware, (i.e., hinges, gimbals or tie-rods). Consult with American BOA for the selection of the most economic expansion joint design. Pipe Anchor A pipe anchor is the point along the piping system where the pipe is fixed. The anchor must restrain the pressure thrust, the spring forces of the bellows and the friction of the pipe guides. The distance between the pipe anchors determines the thermal expansion. Anchor force [lbs.] = pressure thrust + spring force + friction Pipe Guides / upports Pipe guides prevent pipe instability (squirm, buckling) and control bellows movements. Pipe supports must support the weight so it does not adversively affect the bellows. It is recommended that an expansion joint be installed near a pipe anchor and two pipe guides be located on the opposite side of the expansion joint. If this is not possible, two pipe guides are required on each side of the expansion joint. Refer to the figures below for orientation and EJMA for appropriate spacing. Fatigue Cycle A fatigue cycle is defined as one complete movement from the initial position in the piping system to the operating position and back to the initial position. The movement capacity (rated movement) of expansion joints and expansion compensators stated in this brochure refer to 1000 full fatigue cycles. If more than 1000 fatigue cycles are necessary to meet special plant design requirements, the permissible movement shall be determined as follows: Fatique Cycle Table A No. of Cycles Permissible movement 1000 100% 00 63% 10000 52% 5

Temperature (rated) The rated temperature is the maximum temperature to which rated pressures and movements can be utilized. Refer to the data sheets for the temperature rating of the individual expansion joints / compensators. Pressure (rated) The rated pressure is the maximum permissible operating pressure at rated temperature. The design allows for a test pressure of 1.5 times design pressure. The data sheets of each design identify the rated pressure. Movement (rated) The rated movement is the amount of thermal expansion a bellows can absorb at the rated temperature, pressure and fatigue cycles. The movements specified in this catalogue are non-concurrent. Refer to the table below to determine the affect of movement on fatigue cycles. Fatigue Cycle Table (B) Percentage of movement utilized Expected no. of fatigue cycles 100% 1,000 75% 2,700 % 10,600 25% >100,000 Concurrent Movements Movements are concurrent when expansion joints are utilized to compensate for combined movements in axial, lateral and angular directions. The allowable concurrent movements shall be determined as follows: 1 From this catalog, select an expansion joint that will accommodate all movement (axial, lateral and angular) requirements. elected movements shall be larger or equal to the required movements. 2 Calculate the degree of utilization for each movement by dividing the required movement by the rated movement and sum the numbers. In order to determine the concurrent movement capability, the sum shall be less or equal to 1.0. Req. axial movement Rated axial movement Req. lateral movement + + Rated lateral movement Req. angular movement Rated angular movement <=1.0 If the sum is >1.0, select an expansion joint with a larger movement capacity and repeat the calculation. If more than 1000 fatigue cycles are required, refer to Table A to determine the permissible movements. Welding End A weld end is a pipe stub that is welded to the end of a bellows. The weld ends are beveled for joining the expansion joint / compensator to the piping. Flanged End A flange welded to the end of a bellows. It allows the expansion joint to be bolted to mating flanges. Van toned End A van stoned end of a bellows is fitted with a floating flange. The flange can rotate and allows for easy alignment of the bolt-holes with the mating flange. 6

election Guidelines Identify all existing pipe anchors, including all equipment connections in the piping system. When flexible Bellows Connectors are used to dampen vibration of rotary equipment a pipe anchor shall be located adjacent to the connector. Typical installation of BCT pump connectors Discharge Anchor uction Anchor Determine the expected thermal growth of each pipe section between anchors. (Refer to table 1 for thermal expansion coefficient). Determine how many temperature cycles the piping system will experience during the design life of the plant. (Example: The design life of the plant is 20 years and the system will be started and shut-down times per year, the total number of cycles will be 1000). 20 years x = 1000 cycles. Determine the pressure rating of the system in consideration of the design pressure and temperature. From the data sheets in this catalog, select an expansion joint, expansion compensator, vent or flexible connector that meets the design conditions with regard to material, pressure, temperature and movement ratings. If the required movement exceeds the permissible movement of any standard expansion joint or expansion compensator listed in this catalog, allow for additional intermediate pipe anchors that will reduce the distance between anchors and subsequently the amount of thermal growth per pipe section. pecify additional expansion joints / compensators or consult American BOA for design options.

AMERICAN BOA, INC. TANDARD INDUTRIA EXPANION JOINT ERIE RV Vent Connectors Vent Connectors are engineered to withstand the turbulent and high velocity flow that is typical for vent lines. American BOA RV Vent Connectors provide a completely closed venting system between the pressure relief or safety valve and the silencer. American BOA RV Vent Connectors eliminate the risk of uncontrolled discharge of flow media inside a building which may occur if drip-pans are used and the back-pressure exceeds design predictions. American BOA RV Vent Connectors utilize multi-ply bellows technology that is superior to any other bellows design in handling high frequency, flow induced and mechanical vibration. The compact design provides large movement capacity with the lowest possible spring rates. This design reduces forces and moments at the valve and other equipment connections. tandard RV bellows are made of 321 tainless teel for enhanced corrosion resistance. The RV design also features a full-bore liner for unrestricted flow and a heavy wall housing that provides protection against damage and uncontrolled discharge of flow. A drain nozzle to remove condensate is standard.

INTAATION INTRUCTION American BOA flexible metal products are engineered to meet the special requirements of the ight Industrial markets. They are designed to withstand common handling, shipping and installation practices while providing superior flexibility to compensate for the thermal growth of piping systems and to control vibration of rotary equipment. They are extremely safe and increase plant reliability. The following guidelines shall be used to ensure the proper function of expansion joints, expansion compensators or other flexible metal products during service. Check the product for any visual damage, especially for dents in the bellows, broken or bent shipping bars or preset tabs. tore the product in a clean and dry area, ensure that no obstacles are jammed between bellows convolutions or have entered the inside of the expansion joint or compensator. Protect the bellows against weld splatter whenever welding near adjacent piping. Do not attempt to strike an arc on any part of an expansion joint, especially the bellows. When installing expansion joints with fixed flanges, do not attempt to torque the bellows if the boltholes do not align with the mating flanges. It is a good practice to weld one mating flange to the pipe after the expansion joint is bolted to this flange or utilize expansion joints with a van stone flange. Exercise caution when applying torque to the bolts of flanged expansion joints to avoid damaging the bellows. It is good practice to have the head of the bolts facing the bellows and the nuts facing the mating flanges. Do not use expansion joints to compensate for excessive piping misalignment unless explicitly permitted. Do not remove bellows covers, shipping bars or preset tabs before the installation is completed and all pipe guides, supports and anchors are firmly installed and secured. Do not remove shipping bars, preset tabs or temporary bellows covers until all pipe anchors, supports and guides are in place and secured. Never exceed the permissible test pressure. Avoid pressure peaks that may occur when filling the piping system too rapidly. Avoid water and steam hammer. Handling and installation instructions are included in all American BOA flexible product shipments. Ensure that the personnel handling and installing the products are aware of these guidelines. Installed correctly, American BOA expansion joints, expansion compensators, RV s and flexible connectors will ensure safe and reliable plant operation with a life expectancy often surpassing other equipment.
