2 Basic information Hoses are designed to convey all types of media flexibly from A to B. Depending on the formulation, they must withstand very different pressures, media, consistencies and temperatures. Your advantages Reduced wear in hose lines and pipelines Simplified handling for coupling operations Customer-specific special versions from DN 13 to DN 100 However, they are not designed to cope with mechanical loads such as tensile forces, abrasion, bending or torsion. Some problems can be alleviated by proper handling. However, they can also be solved by using suitable fittings and systems by RS. Take the torsion problem, for example. RS has it all figured out and simply transfers the rotary forces from the overloaded hose to fittings that are specially designed for the purpose. The advantage is obvious: The once-off investment in highquality and long-lasting swivel joints turns the consumable hose into longer-lasting component of the hose line. And a long-lasting product represents a pure cost saving. Application areas Loading processes Coupling stations Filling processes 2

And a long-lasting product represents a pure cost saving. Hoses are an investment. However, the situation is often different in practice. Careless handling quickly leads to damage, therefore resulting in costs. Careful handling, on the other hand, extends the lifetime of the hose and saves money in the process. This applies in virtually all sectors involved in professional fluid handling. Two non-return valves on both coupling halves ensure that the sectioning points of the line are safely when the coupling is released. In the operating state, the two spring-loaded non-return valves brace each other in such a way that keeps the line cross-section open and guarantees the maximum flow. In the case of separation, the two valves immediately close each cross section being released.

9 Hose swivel joints SDL/SDS Swivel joints for direct installation in the hose line Hose swivel joints SDL/SDS Swivel joints for direct installation in the hose line Torsion protection that is fitted directly in the hose universally deployable for hose lines that are moved at regular intervals, such as those in loading, filling, and tanking systems or mixing stations. RS hose swivel joints are swivel joints with an integrated hose support. The direct connection to the hose line is similar to the hose couplings in accordance with EN ISO (DIN 2817) for the SDL hose swivel joint or in accordance with EN ISO (DIN 2826) for the SDS hose swivel joint. Its use means that an additional fitting is no longer required. The resulting interface, which can form an additional wear point or a potential leak, is thus also eliminated. Particularly when dealing with steam, hose swivel joints are a popular variant. They are used in the chemicals sector, in plant engineering and power plant construction and in hose stations. Hoses are designed to convey all types of media flexibly from A to B. Depending on the formulation, they must withstand very different pressures, media, consistencies and temperatures. However, they are not designed to cope with mechanical loads such as tensile forces, abrasion, bending or torsion. Some problems can be alleviated by proper handling.

11 Machine swivel joints DGLL Swivel joints for freedom of rotation even under pressure Machine swivel joints DGLL Swivel joints for applications where freedom of rotation must remain high even under high pressure Torsion protection that can be fitted along the line with industrial bearings - for use in mechanical engineering/ robotics for hose lines that are subjected to constant movement. The DGLL machine swivel joint was specially developed for mechanical engineering in conjunction with users, e.g. for robotics applications with extreme loads. In the automotive industry, for example, production frequently takes place around the clock. The swivel joint must turn reliably and precisely thousands of times per day. An error that occurs here puts the entire production process at risk. Time-consuming and costly maintenance work can only be carried out while machines are at a standstill. It s a situation that calls for a reliable product. The extremely long-lasting DGLL machine swivel joint stands out because it uses an industrial ball bearing along with particularly low-friction X-rings as the sealant. This significantly reduces the influence of the medium s pressure on the swivel joint s ability to move compared with a standard swivel joint. As a result, the DGLL, which is particularly smooth-running compared with conventional swivel joints especially when under pressure, is also ideal for use in applications involving high load changes in robotics as well as in mechanical and plant engineering. Application Smooth-running rotary connection e.g. for robot arms Highly versatile for different industries Your advantages Low friction even during rotational movements under pressure Adjustable Easy to clean Reliable even at the lowest pressure Compact construction Easy to maintain Permits modular use Long lifetime prevents hose torsion 11

Application examples A smooth operator Among the RS swivel joints/ball swivel joints, the DGLL machine swivel joint stands out because it uses an industrial ball swivel joint along with low-friction X-rings as the sealant. It also makes it ideal for use with high load reversals in robot technology and in mechanical and plant engineering. 12

13 Steam swivel joints DDG Swivel joints specially for use with steam/hot water Steam swivel joints DDG Swivel joints specially for use with steam/hot water Double-row torsion protection that can be fitted along the line specially developed for use with steam and hot water with steam-proof seals and suitable for the high proof pressures in steam hoses. The steam swivel joint is a variant of the radial stress-resistant, double-row swivel joints with a particular focus on steam or hot-water applications. Unlike standard double-row sealing joints, the sealant is made of a special, steam-resistant elastomer. The structure of the swivel joint is particularly robust so that the swivel joint can also withstand the increased requirements of a steam hose pipe test with 5 times the testing pressure. The wall strength was also increased. Steam and hot water is used in industry either as a heat exchanger or as a cleaning or sterilisation medium. In addition, the specially developed steam hoses are not protected per se against damage due to torsion. In these situations, the use of a swivel joint is a proven means of protecting the steam line from damage. Depending on the temperature range or pressure of the medium to be transferred, steam or hot water can pose a significant hazard for the operators of a steam hose line should the hose line fail due to wear and tear. Application Steam Hot water Your advantages Adjustable Easy to clean Reliable even at the lowest pressure Compact construction Easy to maintain Permits modular use Long lifetime Prevents hose torsion 13

15 Abrasive swivel joints ADG Swivel joints, keeping solid matter away from sealants Abrasive swivel joints ADG Swivel joints in which e.g. solid matter is kept away from the sealants Torsion protection that can be fitted along the line with integrated solids stripper for use with liquids containing solid matter. The abrasive swivel joint is a version of the radial stress-resistant, double-row swivel joint featuring an additional stripper made of PTFE. The stripper prohibits the penetration of solid particles into the sealant area. This significantly increases the gasket s idle time in comparison to the standard swivel joints. The fluid to be loaded is not always free of solid matter. Particularly when transporting crude oil or in the paint and coatings industry, the media contain solid matter such as sand and pigments. In conventional swivel joints, this solid matter can very quicklycause the mechanical destruction of the seals used. For this reason, the abrasive swivel joint is equipped with a stripper, which is fitted in front of the actual seal. This prevents the solid matter coming into contact with the seal in the first place. The service life of a swivel joint used to convey solid matter or abrasive media is thus significantly extended. This saves maintenance and repair costs and enhances safety during the loading process. Application Media with solid matter content Paints and coatings (pigments) Your advantages Not sensitive to solid matter in the medium Easy to clean Reliable even at the lowest pressure Compact construction Easy to maintain Permits modular use Long lifetime Prevents hose torsion 15

17 Radial stress-resistant swivel joints QDG Swivel joints specially for use under high transverse loads Radial stress-resistant swivel joints QDG Swivel joints specially for use under high transverse loads Torsion protection with double ball paths that can be fitted along the line to be used in all situations where processrelated higher lateral forces are exerted on the swivel joint. The radial stress-resistant swivel joint is an enhancement of the standard swivel joint for applications involving higher mechanical loads, such as those caused by bending moments. It is equipped with two ball paths in order to securely absorb any possible moments and radial forces. This alleviates the strain on the seal in the swivel joint and increases the lifetime of the swivel joint. Depending on version or installation position of a hose line or pipeline, the swivel joint may be subject to a transverse load ( bending ) e.g. due to the weight of the hose line or pipeline. Conventional swivel joints are not sufficiently dimensioned for this type of load. This is where the radial stress-resistant swivel joint comes into play. Equipped with structural measures such as two ball tracks and, depending on the version, two seals, it is capable of absorbing these radial forces. Compared with a conventional swivel joint with just one ball track, the radial stress-resistant swivel joint offers a significantly longer service life and therefore lower maintenance and repair costs under the given operating conditions. Application Heavy or very stiff hose lines Pipelines Your advantages Absorbs bending moments and radial forces Easy to clean Reliable even at the lowest pressure Compact construction Easy to maintain Permits modular use Long lifetime Prevents hose torsion 17

19 Ball swivel joints KDG Swivel joints with angle compensation, swivel angle: 50 Ball swivel joints KDG Swivel joints with angle compensation, swivel angle: 50 (+/- 25 from the axis) The patented RS ball swivel joint was designed primarily to prevent the kinking and torsion of hose lines. With a swivel angle of approx. 50 overall, it effectively improves the capacity of hoses to bend without being damaged. This prevents many types of damage that are otherwise caused by tight bending of hoses. The flow characteristics of our ball swivel joint are optimised to avoid any narrowing or protruding edges in the flow of product. The swivel angle of 50 can be further increased by using several RS ball swivel joints connected in series. The RS ball swivel joint not only expands the freedom of movement of the hose line, but also make life easier for service staff and relieves the burden on maintenance personnel. It s an all-rounder product that can be used for applications in practically every sector involved in professional fluid handling.

22 Technical annex Threads and flanges Threads and flanges Threaded connections In principle, threads are classified as hose and tank units independent of the thread type. A threaded connection allows the transmission of high axial forces. In the application area of fittings, tensile forces can be absorbed on the one hand and the sealing forces required to make the connection medium- and gas-tight can be produced on the other. To establish such a connection between a hose and tank unit, the threads to be connected must be compatible. This is achieved by using compatible geometrical thread parameters whose characteristics are defined in the various standards for the different thread types. The selection of a thread type is particularly influenced by its prevalence in the respective fields of application. The following overview is intended to help you identify the suitable thread type. Overview of threads commonly used in valve technology Description Description Standard Application areas General International G-thread BSP DIN EN ISO 228 R-thread BSPT DIN 2999/EN NPS NPS ANSI/ASME B General industry NPT NPT ANSI/ASME B /3 Milk pipe round thread Round thread DIN Foodstuffs, Pharmaceutical ACME ACME ASME B1.5 Gas Metric ISO-thread Metric thread DIN 13 Hydraulics 51/2" rail tank wagon thread DIN 11 Loading rail tank wagons Overview of identifying features Description Male thread Female thread G-thread cylindrical cylindrical with seal R-thread conical cylindrical without seal NPS cylindrical cylindrical with seal NPT conical conical Milk pipe round thread cylindrical with seal cylindrical ACME cylindrical with seal cylindrical with sealing face Metric ISO-thread cylindrical with cone cylindrical with conical face 51/2" rail tank wagon thread cylindrical cylindrical with seal Overview of types of seal Bezeichnung Dichtform Dichtpunkt Kompatibilität Hinweise G-thread flat Thread seal R-thread if AG flat sealing R-thread conical Thread + sealing band G-thread if AG flat sealing NPS flat Thread seal NPT NPT Thread Thread + sealing band NPS if AG flat sealing Milk pipe round thread flat Thread seal ACME flat Thread seal Metric ISO-thread conical Cone/metallic 24 or 60 degree cone 51/2" rail tank wagon thread flat Thread seal 22

23 Technical annex Threads and flanges For safety fittings with a threaded connection generally only use BSP and NPT threads: NPT BSP Flanged connections Flange connections are classified as so-called swivel flanges and fixed flanges. The swivel flange connection is characterised by a freely rotatable flange disk positioned on a fitting. On this flange disk, the bolt holes required for the connection are evenly arranged in a circle. This allows changing the bolt holes position by rotating the flange disk around its longitudinal axis. The opposite is true for the fixed flange connection - here the bolt holes are arranged on a disk firmly connected with the rest of the fitting. Thus, the bolt holes cannot be positioned independently of the rest of the fitting. As a rule, hose lines with flange connections are equipped with a swivel flange on the one hand and a fixed flange on the other. This way, torsions that can damage the hose or hinder its use can be avoided. Connections between two swivel flanges, two fixed flanges as well as between a swivel flange and a fixed flange are possible and permitted in the case that both connecting units are compatible. 4.1 Explanation flange tables ØD (Diameter) Øk (Hole circle diameter) n (Number of holes) ØL (Hole diameter) C (Thickness) 23

24 Technical annex Threads and flanges Two flange connections are compatible when both flanges are designed in accordance with the same technical standard and, if applicable, for the same pressure rating. The technical standards and the pressure ratings that may be contained therein provide information on the dimensioning of the connection-relevant measures.

26 Technical annex for fitting bodies For a wide range of valves, there are also a large number of possible materials. Depending on the fitting, these materials are selected based on standards and/or applications. Factors such as strength, chemical and thermal resistance as well as manufacturing processes play a major role in the choice of material. The following main groups products are used in the most diverse variants and qualities in valve technology: Overview of the most widely used materials in valve technology by manufacturing process Material groups Machined (turned/milled) Cast Forged Injected Steel , , , Stainless steel 2A grade , , Stainless steel 4A grade (1.4571), , , Hastelloy (2.4610), , , Brass CW614N, CW617N CW614N, CW617N CW614N, CW617N Aluminium EN AW-6060 EN AC EN AW-6082 Plastics Polypropylene, PEEK, PTFE, POM Polyamide For safety coupling stainless steel, aluminium or (rarely) brass are usually used. 26

27 Technical annex for seals The large number of thread and coupling seals require a variety of materials for seals. Elastomeric seals are common for this purpose. These include: Overview and characteristics of the most widely used sealants in fitting technology Material Chemical properties Physical properties FKM/FPM (VITON ) 1 NBR (Perbunan ) 2 Polyurethane (VULKOLLAN ) 3 PTFE (TEFLON ) 4 CSM (HYPALON ) 1 Good general chemical resistance good ozone & weathering resistance Good resistance to petroleum & fuel limited ozone & weathering resistance Good resistance to petroleum & fuel poor chemical resistance Universal chemical resistance good ozone & weathering resistance Good acid & lye resistance good resistance to petroleum & fuel High temperature resistance at water & water vapour max. 60 C operating temperature C Good mechanical properties (abrasion resistance) good low-temperature behaviour temperature range C Good mechanical strength (wear & tear resistance, elasticity) operating temperature C Good anti-friction properties high temperature resistance operating range C Good mechanical strength (wear & tear resistance, elasticity) operating temperature C FFKM excellent chemical resistance High temperature resistance (KALREZ ) 1 operating range C Novapress Multi EPDM Good steam & hot-water resistance good resistance to petroleum & fuel Good steam & hot-water resistance poor resistance to petroleum & fuel good ozone & weathering resistance High pressure resistance operating range C Good mechanical strength (wear & tear resistance) operating temperature C (1 = Dupont Performance Elastomers L.L.C. / 2 = LANXESS Germany GmbH / 3 = Covestro Germany AG / 4 = The Chemours Company FC, LLC) Depending on the particular application, a suitable sealant must also be used in addition to the suitable valve material. Please contact the manufacturer of the safety fittings for assistance in choosing an appropriate seal. Surface finishing / surface protection Corrosive media call for special fittings which provide suitable surface protection. For protection against aggressive media such as acids and lyes, highly chemical-resistant fluoroplastic coatings are used. These include PTFE, FEP, E-CTFE, ETFE, or PFA. This coating is applied to areas that come into contact with the media. Unfortunately, not all parts of a coupling assembly can be coated.in this case highly chemical-resistant materials like nickel-based alloys (e.g. Hastelloy ) are used. 27
