Catalogue 2 - STAUFF Connect

21 www.stauff.com/2/en/#21 A Catalogue 2 § Edition 03/2024 System Overview Pressure Resistance When the STAUFF Form EVO tube forming system is used in conjunction with genuine products from the STAUFF Connect product range, it provides pressure resistance of up to 800 bar in the Heavy Series and 500 bar in the Light Series (generally with a four-fold safety factor and depending on the series, design and size of the fitting body and taking into consideration various pressure reducing factors). This is the result of exceptional care taken in the development of the system and the selection, handling and processing of the raw materials. Maximum tear-out strength can be guaranteed for the system due to the contour shaped at the tube end.

The assembly is completed with another turn by approx.imately 15° to 20° beyond this point. This incredibly simple assembly method has several benefits for the user: ƒ Considerably lower torques and short assembly paths (once the fixed point has been reached) ƒ Significant increase in torque to clearly indicate the end of the assembly ƒ Maximum safety to combat over-assembly ƒ No need for time-consuming and expensive training Connections made with the STAUFF Form EVO can be untightened as often as required and reassembled without wear, as any damaging expansion of the 24° conical bore of the fitting body is technically avoided. Design ƒ Based on standard components including the standard union nut of the STAUFF Connect product range according to ISO 8434-1 – No duplicate storage of simi- lar stocking of similar components with a correspondingly high risk of confusion ƒ Positive-locking connection with an elastomer sealing with a particularly large cross-section to provide secure and permanent sealing even in the event of unfavourable tolerances ƒ Sealing of the only possible leakage path primarily via the STAUFF Form EVO sealing ring as well as the secondary, face sealing ƒ Preservation of the flow behaviour through the optimised shape of the formed tube end Durability and Application ƒ Suitable for both steel and stainless steel tubing as standard – also applicable for alternative tube materials on request ƒ Covers all common metric tube dimensions from 6 x 1.5 mm to 42 x 4 mm in the Light Series and 38 x 6 mm in the Heavy Series respectively ƒ Suitable for nominal pressures up to 800 bar in the Heavy Series – designed with four-fold safety and maximum tear-out strength ƒ The use of FKM (Viton®) as the standard seal material makes the system perfect for the most challenging applications. Thanks to the combined metal- elastomer seal, low-temperature ranges down to -35° C are possible without restriction ƒ High-quality zinc/nickel surface coating provides maximum protection and cor- rosion resistance – standard for all parts in the STAUFF Connect range Assembly Tools and Devices ƒ Robust table-top device for continuous operation in the workshop ƒ High efficiency of the system with low cycle times ƒ Optimum tool concept with exchangeable internal tube supports, so that only a small number of tools is required to cover all tube diameters ƒ Intuitive operation via touchscreen ƒ Cloud connection as well as machine briefings and trainings ƒ All tools needed for the forming process clearly labelled with the tube dimen- sions so that assembly errors caused by incorrect assignment can be largely ruled out ƒ Short times required for tool changes as clamping jaws, tube shaper and inter- nal tube supports can be simply replaced without the need for any tools ƒ Attractive maintenance packages to ensure best possible service ƒ Low insertion depths compared to alternative systems for even more complex tube geometries and smaller bending radii Final Assembly ƒ Incredibly simple final assembly in the fitting body with low assembly torques as well as short assembly paths (once the fixed point has been reached) with a minimised risk of over-assembly ƒ Assembly errors are consistently avoided due to the laterally identical profile of the sealing ring ƒ Connections can be untightened as often as required and reassembled without wear, as any damaging expansion of the 24° conical bore of the fitting body is technically avoided ƒ No need for time-consuming and expensive training Features
