Ideal storage is a warehouse with a relatively dry, cool location. Store flange face down on a pallet or wooden platform. Do not store other heavy items on top of a Thorburn expansion joint. Ten year shelf-life can be expected with ideal conditions. If storage must be outdoors, Thorburn’s joints should be placed on wooden platforms and should not be in contact with the ground. Cover with a tarpaulin. Large joint handling. Do not lift with ropes or bars through the bolt holes. If lifting through the bore, use padding or a saddle to distribute the weight. Make sure cables or forklift tines do not contact the rubber. Do not let Thorburn expansion joints sit vertically on the edges of the flanges for any period of time. System tests should not exceed 150% of the rated working pressure of the expansion joints. Systems should not be operated above the rated pressure or temperature of the expansion joints. Insulating over expansion joints is not recommended. If insulation is required, it should be designed for easy removal so the periodic in- spection procedure can be maintained. This facilitates periodic inspection of the tightness of the joint bolting. Welding should not take place in the vicinity of the expansion joints. If welding occurs frequently above the expansion joint, a protective shield shall be installed. If underground installation is necessary, a protective shield over the expansion joint should be provided. Back-filling directly onto the ex- pansion joints is not recommended. Submerged in water. Contact Thorburn for specific recommendations. 48 © 2022 Thorburn Flex Inc

Flangeless valves: Never install spool-type rubber expansion joints next to flangeless butterfly valves or flangeless check valves. Serious damage to the rubber joint can occur unless it is installed against full-face metal flanges. Undue stress: Do not install an expansion joint in a system in an attempt to \"pull\" misaligned piping into position. Retaining rings: Never install spool-type expansion joints without using the back-up retaining rings behind both flanges. Control units: Install control units with a Thorburn rubber expan- sion joint if piping is not adequately anchored or if there is any question that movements may exceed the rated value of the joint. A spare: At the time of installation, consider ordering a spare joint. Although Thorburn expansion joints are engineered to give long, dependable service, the cost of equipment downtime in the event a joint wears out can far outweigh the cost of a spare.

Compare the requirements of the system to ensure the proper number of control rods have been specified (Minimum of two re- quired). w w w.thorburnflex.com 49

The flange is drilled to conform to the bolt pattern of the com- panion metal flanges of the pipeline. Thorburn’s 60RPC is manufactured from high quality elastomers to safely satisfy your chemical abrasion- sound requirements. Specify Thorburn’s 60RPC and you are assured of the highest quality leak tight sound and movement absorbing pump con- nector system in the world. Split Fabric Advantages Retaining Ring Reinforcement Absorbs pipe wall and fluid-borne noise The low sound transmission properties of rubber allow for pipe wall Cross section of Thorburn flanged 60RPC sounds to be absorbed by Thorburn’s 60RPC connector by the volumetric pump connector expansion (breathing of Thorburn’s 60RPC connector). In other words, sound weakens travelling through rubber. Thorburn’s 60RPC length influ- ences sound absorption. Isolates vibration and motion Vibration originating from mechanical equipment is absorbed by Thor- burn’s 60RPC connectors. As most machinery vibrates in a radial direction from the main shaft, Thorburn’s 60RPC should be installed horizontally and parallel to this main shaft. Thorburn’s 60RPC will tolerate minimal axial motion. But for two-plane vibration/motion, it is recommended to use two flexible rubber connectors installed at right angles, one to absorb the horizontal vibration and one the vertical vibration. A tension anchor is usu- ally needed to stabilize the elbow between the connectors. Thoburn Model 60RPC flanged pump connector Piping system misalignment compensation with control rod assembly Type “CR” Installation in a rigid piping system is facilitated and Thorburn’s 60RPC connectors add a flexible component that is automatically self correcting for misalignment created by structural movements caused by thermal ex- pansion or ground shifts. See page 40 for product specification details. Reduce system stress and strain Rigid attachment of piping to critical or mechanical equipment can pro- duce excessive loading. Thermal or mechanically created strains-stress- shock are cushioned and absorbed with the installation of Thorburn 60RPC. Full flow with less turbulence or material entrapment Thorburn’s 60RPC connectors’ smooth rubber lining allows full flow with- out turbulence. Metallic connectors depend upon bellows or convolutions to absorb motion. These bellows/convolutions can create flow turbulence and also create an area for material entrapment or bacteria growth. Thoburn Model 60RPCX swivel flanged pump connector with acoustical control cables Model TACC WARNING: Control unit cable or rod assembly usage: Thorburn control units are designed to protect Thorburn 60RPC connector from excessive elonga- tion. Control rods are always recommended as a protection against: 1) thermal shrinkage in the piping, 2) hydrostatic tests at elevated pressures and 3) line pressure surges. Thorburn control rods must be used: 1) when the piping containing the rubber connector is not anchored and 2) when the rubber connec- tor is attached to unsupported pipe or equipment. w w w.thorburnflex.com 51

Available with factory assembled permanently attached crimped ends Construction TUBE: Available with various tube compounds wall thickness with w w w.thorburnflex.com smooth or corrugated construction as determined by the application and the media. Please call Thorburn for details. REINFORCEMENT: Multiple layers of precisely angled cross woven cal- endared fabric. The 60TMH has integrally built in evenly spaced heavy duty helix spring wire or annular rings that withstand the rated working pressures from full vacuum to 1000 psi (70 bar). Can be designed to support a minimum bend radius from two times the diameter or maintain unsupported rigidity over long lengths. The 61TMH can be rolled up for easy handling and storage. Please call Thorburn for details. COVER: Available with various cover compounds and wall thicknesses with smooth or corrugated construction as determined by the application and the media. Please call Thorburn for details. SIZES: 1/2\" (12mm) to 48\" (1200mm) I.D. up to 100ft (30m) long. Longer lengths available on special order only. SPECIAL NOTES: 1. Thorburn’s 60TMH/61TMH assemblies are custom designed for specific applications, therefore the construction may vary depending on pressure, bend radius requirements & media. 2. The standard bend radius for 60TMH is typically 6X ID (61TMH bend radius N/A). 3. Corrugating the 60TMH cover and tube will improve the bend radius at lower pressures. 4. Incorporating annular rings with a smooth tube and cover will improve the bend radius at high pressures. 5. The forces required to make a 60TMH bend have a direct relation to the pressure. 6. Arches can be added to the 60TMH to provide axial movement. 7. Special end configuration (other than shown) are available upon request. For ordering information, please see pages 56 & 57 for details 55

The hose lengths are designed to be cut to length on site and fitted with Thorburn’s aluminum split cast coupling to provide a readymade site assembled flanged hose. Thorburn’s field attachable split cast couplings are not in contact with the process flow. The hose length can be cut to suit the intended duty, ready for installation. In addition, it allows the re-use of the split cast couplings as the fittings are not in contact with the process flow. 60TMH Split Cast Coupling Hose Assembly Thorburn’s field attachable fitting-to-end joints are an economical solu- tion for quick emergency change out. Thorburn’s reusable multi-drill pattern coupling system enables operators to minimize inventory costs by stocking bulk hose with separate Thorburn clamped ends instead of factory fabricated hose assemblies.
