TECHNICAL INFORMATION

GENERALPipelines, apparatus and systems made of borosilicate glass 3.3 which carry the CEmark, are manufactured and quality monitored in compliance with the Pressure EquipmentDirective (97/23/EC). At the same time, the chemical/physical material characteristics ofborosilicate glass 3.3 and the design of glass components are subject to national andinternational standards.

The type of flange for glass parts is not standardised, but is determined according to theuser's technical demands. Whilst, for instance, a flat safety flange is excellently suited to GMPsystem engineering due to its construction with little dead space, a ball and socketsystem is highly valued for its flexibility.

For this reason, QVF has included the ball and socket pipeline system from the formerSchott catalogue 6076, in this supplement, to the WPR catalogue, as the "KF pipelinesystem" and is manufacturing it with state-of-the-art technology and in line with the afo-rementioned standards and directives as an alternative coupling system for glass systemengineering.

The KF pipeline system has therefore not only been given the CE mark, but certifi-cation for compliance with the Clean Air Act has also been provided for the valves andcouplings. Accuracy of manufacturing, storage and quality control all correspond to WPR2002.

MATERIAL PROPERTIES/OPERATING DATAThe "KF pipeline system" is a supplement to the QVF catalogue "Process Plant Com-ponents", also known as "WPR 2002". Thus, the information given in the catalogue on

- borosilicate glass 3.3, chemical, physical properties

- permitted operating conditions

- dimensioning of components

- labelling of components

- danger analysis and potential hazards

also applies to the "KF pipeline system". You will find the operating data for the valvesin the valves section of this supplement. Any variations are listed for each individualarticle as applicable.

REFERENCE NUMBERSThe Schott KF system from catalogue 6076 is a common coupling system in the fieldsof industry and research. The referrence numbers listed in this catalogue supplement the-refore correspond to those from catalogue 6076. In those instances in which the technicalproperties have been changed, an "N" (new) has been added to the reference number.

Whilst the parts made purely of glass are listed identically to listings in catalogue 6076, for hand-operated valves, for instance, the important dimensions for connection compatibility areidentical, but internal parts have been given a second seal and a cone as standard toimprove regulation. An "N" has been added to the order number for these valves (e.g. VEN25).

KF PIPE ENDSThe designation KF was derived from Schott's German name for the ball and socket system("Kugel-Flansch") and comprises spherically ground sealing surfaces and a shoulder flan-ge for force transmission. In this catalogue, ball pipe ends are all labelled with the codedigit 1 and socket pipe ends with code digit 2. Possible variants are also shown in thedrawings.

You will find the main KF pipe end dimensions in the following table.

ALIGNMENT OF KF COUPLINGSBefore the final sealing force is applied, glass parts can be aligned at an angle to eachother so that horizontal pipelines can be laid with a gradient α without the need for addi-tional components.

The following table shows the maximum permitted angle of alignment by nominal dia-meter for a pipe with a length of 1000 mm.

CONNECTION TO OTHER MATERIALS AND FLANGESYSTEMSConnections can be made to pipelines made of other materials either using bello-ws, in order to compensate for expansion and forces from external material, or usingAMS or AFS glass adapters from WPR 2002. These adapters can also be used to connectto the flat safety flange. This connection can however, be established without the need foran additional glass part, using a CPKFA adaptor coupling.

VALVES & FILTERS

GeneralThe valves of the KF system, with the exception of pressure retaining valves, vent val-ves and drain valves, have the same dimensions for connection as the valves in cata-logue 6076 but also feature the usual internal parts as found in WPR. The combinationof connecting dimensions from the former Schott range with WPR internal parts ensu-res that valves in existing pipelines can be easily replaced and guarantees quick availabi-lity and state-of-the-art technology. Hand-operated valves are fitted with a second seal onthe handwheel as standard.

Permitted operating conditionsThe following operating pressure values, related to nominal diameter, apply for a maxi-mum operating temperature of 180°C:

Because of the shape of the base and cone, bellow valves with a PTFE conecan be used as both shut-off valves or to roughly regulate flow. The throttle fun-ction of these valves is only ensured if the flow is against the cone.

All valves comply with the conditions of the Clean Air Act.

The valve is guaranteed to function properly and ensure the correct direction of flowin pipelines in both a horizontal and vertical installed position.

A solid ball is used in vertical pipelines for gasses, vapours and liquids. A hollow ball isused in horizontal pipelines for gasses and vapours. For liquids in horizontal pipelines, itdepends on the liquid whether a solid or a hollow ball is used. The product comes into contactwith borosilicate glass and PTFE.

These valves can be supplied on request with an O-ring seal in for more extreme imper-meability requirements.

However, it is important to make sure that the ball return valve is not used to provide a lastingshut-off effect. The appropriate valves and ball valves, depending on the individualinstance of usage, must be used for this purpose.

They are used to provide constant back pressure and are best used behind dosingpumps, but also occasionally behind centrifugal pumps (for which an aperture is gene-rally preferred).

A spring is used in place of the usual manual operation featured with other valves. Its ten-sion setting can be changed using a screwdriver. This makes it possible to set all inter-mediate values infinitely variably between 0,5 bar g and the permitted operating pressu-re of the valve, to a tolerance of ± 0,3 bar.

LOADING VALVES

Please specify pressure setting on the order.

During operation it is important to make sure that the sum of the pressure set-ting and pressure loss in the valve is not allowed to exceed the maxi-mum operating pressure for the pipeline.

Loading valves must not be used as safety valves as the necessary appro-val for this type of usage has not been granted.

Angle Valves with Flowserve-Kämmer Actuator

The pneumatic open/close valve with a Flowserve-Kämmer drive is actuated with a sup-ply air pressure setting of 2.5 bar g which must not be exceeded by more than 10%. Thecone on this valve cannot be used for regulation and is used for reasons of compatibili-ty only.

A "1" must be added to the order number for the position "spring opens" and a "2" mustbe added for the position "spring closes".

The regulating performance of the glass control valve is determined by the com-bination of base and cone. Equal percentage or linear characteristic curves can be sel-ected.

In all cases, the ratio according to VDI / VDE 2173 is 25 : 1.

Three different base diameters are available for nominal diameter DN25.

Valves with a base diameter of 4 or 8 which require a higher level of dosing accu-racy, even when exposed to heat, have a cone made of tantalum.

Technical data and installation dimensions of these ball valves are the same as for themanually operated version.

Compressed air is required at 5.5 bar g for single-action actuators with thefull number of springs.

To avoid the sudden build-up of high surface pressure between the ball andoperating spindle at the start of the opening or shutting action, we recom-mend the incorporation of air flow controls in the supply line to the actuator.

When ordering please add a »1« to the catalogue reference if the »spring-to-open« fail-safe version is required or a »2« for »spring-to-close«.

The »spring to open« setting can be changed to »spring to close« and vice-versa by changing the position of the operating spindle in the actuator by90º.

If required, two inductive proximity detectors of hazardous area type EEx ia llC T6 to indicate on/off can be supplied for the actuators.

Maximum tightening torque for screws (Nm)0,81,21,21,21,21,22,82,82,8

GeneralAn important factor for ensuring operational safety and keeping the requirement for main-tenance for glass installations as low as possible is the right choice of flange rings and seals.

The scope of delivery for a flange coupling includes two flange rings and two inserts in theselected material as well as screws, nuts, washers and stainless steel springs. The gas-kets are not included in the scope of delivery and must be ordered separately.

The use of springs ensures that the screw force is set properly and at the same timemakes sure it is maintained once the seal has settled. Take the value for maximum tigh-tening torque from the following table. Stainless steel screws must be greased duringinstallation to prevent the screws from blocking. The values shown below refer to grea-sed screws.

The same couplings can be used for coated glass components. The centring pins onthe plastic inserts must only be removed for nominal diameters DN 200 and DN 300.

The listed order numbers correspond to those from catalogue 6076 wherebystainless steel screws are always used with springs.

These are the couplings which are used most frequently as they are both light-weightand highly resistant to corrosion. No other measures against electrostatic charges arerequired in areas at risk from explosion. The flange rings and inserts are made of fibreglassreinforced duroplastic. Whereas the inserts are hinged, the flange rings are a one-piececonstruction. With the exception of nominal diameter DN 15, they all have a pitch circleand number of bores as per EN1092, PN10 but smaller screw diameters.

When operating acidic products, glass systems may become contaminated by productfrom outside, e.g. mineral acids. In these cases, the silumin flange is used with stain-less steel spiral inserts instead of the duroplast inserts. It is always used in conjunctionwith an NBR/Aramid base. This coupling can be insulated at up to a temperature of200°C.

One exception is hydrochloric acid which can corrode stainless steel and silumin, so inthis case the standard plastic coupling is preferred as it is resistant to hydrochloric acid. If theflanges of an hydrochloric acid system are to be insulated at higher temperatures, werecommend the use of epoxide resin-coated silumin flange rings with plastic or silumininserts.

If couplings with epoxide resin-coated flange rings are required, the let-ter "S" for the material "silumin" must be suffixed with an "E", e.g. SVER25/SEor SVER25/SE/H.

The spacer plate is used if the sealing diameter of the bellows does not come into contactwith the sealing surface of the opposite flange. This is the case with enamel connections, forinstance.

The spacer plate consists of a PFTE cover and a stainless steel core with an additional soft layer.The spacer of all diameters do have a earthing clip.

Support brackets are provided for fastening components with a nominal diameter of DN15 to DN 200 in conjunction with open or closed KK fittings.

Two screws from each coupling are used for DN 15 to DN 50.

The support brackets listed in the following for these nominal diameters aresuitable for fastening both plastic flange rings (as per EN1092) and silumin flan-ge rings.

For DN 100 to DN 200, three M8 threaded rods each are used to install the coupling withthe pipe sleeves which are welded on. Different support forks are required for the variouspitch circles of the flange rings.

The support brackets can be adjusted to the required length on site. The pipe is then clo-sed using the pipe sealing cap which is included in the scope of delivery.

1) When combining EN1092, PN10 flange ring connections, dimension L applies. For other, dimension L1 applies.

The weight of glass apparatus and vertical pipelines is transferred onto the support con-struction by support rings. The support rings have two internal pitch circles; thus they can beused for silumin flanges as well as fir plastic flanges. The support rings are fastened to thestructure using RRM... pipe frame round nuts on the supporting construction.

For pipelines up to and including DN 100, GEGA… support forks are used in place ofsupport rings.
