Because the mechanical properties and production methods for glass fibre reinforced (GRP) flanges are different from those of steel flanges, the dimensions are different (the most important difference is the larger flange thickness). This Wavistrong Flange Guide gives an overview of the commonest flange standards. This guide contains general data concerning the recommended gaskets and the accompanying torques. These data are based on calculations, practical experience and test results. It is not possible to give the ideal solution for all situations that may arise. For this reason you should consult the gasket supplier for special applications. Gaskets, mounting materials and steel/cast iron (blind) flanges are not included in the Wavistrong product range. Specific information regarding these products can be obtained from the manufacturers or suppliers concerned. Data for various flange standards have been applied to determine the bolt and stud bolt lengths for the commonest flange connections and are shown in tables. The calculation methods for determining the bolt and stud bolt length are shown so that these lengths can be determined for flange connections that have not been included. In this Wavistrong Flange Guide certain starting points have been used for calculating a number of data. In the case of differing views concerning the chosen starting points the calculation should be made anew.

Wavistrong flanges are drilled according to current standards which can be categorised as follows: - European standards; - American standards; - Japanese standards. (XURSHDQ VWDQGDUGV
The German standard DIN 2501 applies as the basis for the European standards. This standard indicates the bore of the flanges (outer diameter, pitch circle and number and diameter of the bolts + bolt holes) for various diameters and pressure classes. If another DIN standard is used, this standard relates to a certain pressure class and type of material. The following standards correspond to DIN 2501 regarding the bore: - German standards DIN 2531 up to 2535 - German standards DIN 2631 up to 2635 - German standard DIN 2527 - Standards for cast iron flanges ND 6 up to ND 40 - Standards for steel flanges ND 6 up to ND 40 - Standard for steel blind flanges ND 6 up to ND 100
The following standards have the same bore as DIN 2501, but flange thickness data have not been included in this Wavistrong Flange Guide: - French standards NF 29-221 up to 223 - English standard BS 4504 - International standard ISO 7005 The standards according to DIN 2501 (pressure classes ND 6, ND 10, ND 16, ND 25 and ND 40) are shown in table 1 and table 1a. For some standards the abbreviation PN or NP (Nominal Pressure) is given instead of the abbreviation ND (Nenndruck). $PHULFDQ VWDQGDUGV
Various American standards correspond regarding the bore, as is also the case for the European standards. The American standards can be divided into:- ANSI/ASME B16.5 - ANSI/ASME B16.1 Standard for steel flanges for the diameters up to and including ID 600 (24"). Class 150 and class 300 (psi) are important. Standard for cast iron flanges. Class 125 and class 250 are important. The bores of class 125 and class 250 flanges for the diameters ID 600 and smaller are the same as the ANSI/ASME B16.5 class 150/class 300 flanges. Standard for steel flanges designated for the water industry. Class D (175-150 psi) and class E (275 psi) are important. Both pressure classes have the same bore, only the flange thickness is different. The bores of the ANSI/AWWA C-207 flanges are the same as those of ANSI/ASME B16.1 class 125 flanges. Standard for steel flanges for diameters from ID 300. Class 150 and class 300 are important. The bore of class 150 flanges is the same as that of ANSI/ASME B16.1 class 125 flanges. The bore of class 300 flanges the same as that of the ANSI/ASME B16.1 class 250 flanges up to and including ID 900, for ID 1200 the bore deviates from the ANSI/ASME B16.1 standard. Standard for steel flanges for diameters from ID 700. Class 75 and class 150 psi are important. The bores of this standard do not correspond to another American standard.

It would not be correct to assume that an ANSI/ASME B16.5 class 150 flange is suitable for a pressure of 150 PSI (approx. 10 bars) and therefore corresponds to a DIN ND 10 flange. The design temperature of the ANSI/ASME flanges is much higher than that of DIN flanges, so that at the same temperature the load bearing capacity of ANSI/ASME flanges is significantly higher than that for DIN flanges. This also applies to the class 300 flanges. 1% Because the ANSI/ASME B16.5 is an important and often applied standard (in America), it is often simply assumed that this standard is applied. The tables then show, for example: class 150 or 300 lbs. In older documentation and catalogues the indications ASA 150 and ASA 300 are still found for the bores. It is preferable to abandon the ASA notation and to refer to class 150 (or class 300), giving the standard in brackets. The bores of the American standards are shown in table 2 and table 2a. -DSDQHVH VWDQGDUGV
The Japanese standard JIS B 2210 specifies the primary dimensions of steel flanges for nominal pressures of 2, 5, 10, 16, 20, 40 and 63 bars. These pressure classes are indicated as 2K, 5K, etc. Flanges with the classification 10K are found as normal and thin type. Only the classes 5K and 10K (normal type) are included in this Wavistrong Flange Guide. The flanges can be found in two material types, steel and grey cast iron. The bores of 5K and 10K flanges are shown in table 3. $16, $3, $6$ $::$ %6 ',1 ,62 066 1) -,6 (67 &67 (:7 *53 1' 13 31 ,' 'X 'VW G 7) 72 W S ([SODQDWLRQ RI DEEUHYLDWLRQV = = = = = = = = = = = = = = = = = = = = = = = = American National Standards Institute American Petroleum Institute American Standard Association American Water Works Association British Standard Deutsches Institut fr Normung International Organization for Standardization Manufacturers Standardization Society Norme Franaise Japanese Industrial Standards type indication for Wavistrong standard products (Epoxy Standard Tensile resistant) type indication for Wavistrong electrically conductive products (Conductive Standard Tensile resistant) type indication for Wavistrong products for drinking water applications (Epoxy potable Water Tensile resistant) Glassfibre Reinforced Plastic Nenndruck (nominal pressure) nominal pressure internal diameter outer diameter flange diameter pitch circle diameter bolt holes thickness GRP flange thickness steel slip-on flange thickness steel or cast iron flange gasket thickness

Wavistrong flanges are designed with a flat sealing face. For sealing a connection with Wavistrong glass fibre reinforced flanges a choice can be made from a number of gasket types depending on the diameter, internal pressure, type of flange, medium and temperature. When fitting against flanges with a raised face a bending moment will occur in the flange neck when tightening the bolts. This means that the allowable torque must be adjusted, or that precautionary measures must be taken against non-permissible loads. *DVNHWV specification model manuf. / type sup. / type application specification model manuf. / type : : : : : : : : depending on medium and temperature Full Face, p = 3-5 mm Phoenix Benelux, St. Niklaas (Belgium) Eriks, Alkmaar (Netherlands) see table 4 depending on medium and temperature Raised face, p = 4-11 mm Kroll & Ziller, Hilden (Ger.), type G-St-P/S (for the DINbores ID 25 - ID 1200 and the MSS SP-44 bores ID 700 ID 1200) Kroll & Ziller, Hilden (Ger.), type G-St-P/K (for the ANSI B16.5-bores ID 25 - ID 600) Eriks, Alkmaar (Neth.), type Elastomet-OR/ElastometOR/K

Tables 5a up to 5d give general values for the torques and serve only as a guideline. The torque depends on a large number of factors, so that no exact value can be given for the torque relating to a certain diameter for a certain bore. The gasket supplier should be consulted for the precise calculation of torques. The starting points for the calculation of torques for various types of gaskets: - hexagonal bolts DIN 931 class 8.8 - standard bolts lubricated with Molykote; friction coefficient = 0.1 K = 0.142 - surface pressure for - rubber gasket with inlay: - 12 N/mm2 - rubber gasket with steel inlay: - 10 N/mm2 - rubber gasket with support ring: - 12 N/mm2 - graphite gasket with metal foil: - 25 N/mm2 7DEOH D ID mm 25 40 50 80 100 150 200 250 300 350 400 450 500 600 700 750 800 900 1000 1200 7RUTXHV UXEEHU JDVNHW ZLWK LQOD\ IXOO IDFH Torques (Nm) for rubber gasket with inlay (Phoenix) Bore DIN ND 10 DIN ND 16 DIN ND 25 DIN ND 40 Class 150 50 40 100 55 120 100 80 130 225 195 290 265 390 520 250 385 360 150 100 155 220 220 325 445 400 445 420 585 505 555 775 775 825 855

The sealing surface of the flanges is provided with two grooves, the purpose of which is to create an efficient seal when a hard gasket is used. These grooves also ensure that the gasket does not get blown out by internal pressure. 7DEOH ID mm 'LPHQVLRQV IODQJH JURRYHV DU1 mm 25 35 40 50 50 60 80 100 150 200 250 300 350 400 450 500 600 700 700 750 800 800 900 1000 1000 1200 90 110 160 210 260 310 380 430 500 530 630 730 725 780 830 830 930 1050 1035 1245

Wavistrong flanges are mounted using bolts and/or stud bolts with washers and nuts. The following situations have been assumed for determining the bolt length: - Wavistrong flange against steel or cast iron flange; - Wavistrong flange against steel or cast iron blind flange; - Wavistrong flange against Wavistrong flange; - Wavistrong flange against Wavistrong blind flange. The Wavistrong flange can be a normal flange, a heavy duty flange, an orifice flange or a blind flange, about which it is important to note that the mounting of two blind flanges against each other and of an orifice flange against an ordinary (non-orifice) flange does not arise. For flange thickness and various standards for steel and cast iron flanges see tables 8 up to 10. For flange thickness and various standards for steel and cast iron blind flanges see tables 11 up to 13. For flange thickness of Wavistrong flanges see tables 14 up to 16. For flange thickness of Wavistrong blind flanges see table 17. Hexagonal bolt specification according to DIN 931 and DIN 933 in the various kinds of material and surface treatments (for available trade dimensions of bolts see table 20). Hexagonal bolt specification according to DIN 934 in the various kinds of material and surface treatments (for dimensions see table 19). Stud bolt specification according to DIN 975 in the various kinds of material and surface treatments. Washer specification according to DIN 125 A in the various kinds of material and surface treatments (for dimensions see table 19).
