Transitional coupling type 750The transitional coupling of 750 type allows to reduce a stream of the transported environment directly . The coupling of 750 type of a prednazanchen for replacement of two couplings and a transitional fitting also has special reducing laying for the consolidation sensitive to pressure. The special washer preventing calling of a pipe of small diameter a pipe of bigger diameter at assembly of vertical systems is offered on demand. Case: Malleable cast iron according to ASTM A-536, a class 65-45-12. Malleable cast iron according to ASTM A-395, a class 65-45-15 is offered to order. Case covering: Orange enamel • Option: With hot galvanization and others Laying: (to choose *): • Class "E" EPDM (all other sizes) of EPDM (a green code). Temperature range is from -30 °F to +230 °F/-34 of °C to +110 °C. It is recommended for cold and hot water supply in the specified temperature range, for various diluted acids, air without impurity of oil and other chemical compounds. It is certified on UL according to ANSI/NSF 61 for cold +86 °F/+30 °C and hot +180 °F/+82 °C of drinking water supply. It is not RECOMMENDED FOR USE IN OIL-CONTAINING ENVIRONMENTS. • Class "T" nitrile Nitrile (orange code). Temperature range is from -20 °F to +180 °F/-29 of °C to +82 °C. It is recommended for oil products, air with the content of vapors of oil, vegetable and mineral oils in the specified temperature range. Higher than +150 °F/+66 °C or for hot dry air above F/+140 °F/+60 °C are not recommended for hot water. * The listed applications are only the general recommendations about application. There are scopes for which use of this laying are not recommended . See the last index of laying of Victaulic where rekomenovanny and unrecommended cases of their use are specified. • Option: assembly washer: galvanized, carbonaceous steel of Screws/nut: The tempered galvanized carbonaceous steel conforming to physical and chemical requirements of ASTM A-449 and physical requirements of ASTM A-183. LOSS of the PRESSURE Loss of a pressure after the transitional coupling of 750 type is insignificant and practically same, as at a standard short transitional fitting. Equivalent lengths of a steel pipe of standard weight are specified in the table. Data are based on a water consumption at ambient temperature. The GENERAL NOTES * the Working pressure and face loading are the sum of all internal and external loadings on the basis of the standard weight of a steel pipe (ANSI), with the pressed and fine-molded flutes according to the Victaulic specifications. Okharakteristika of other pipes apply for information to Victaulic. The maximum working pressure is based on data on pipes of big diameter. The nominal rate of the maximum face load is based on data on pipes of small diameter. PREVENTION: FOR SINGLE TEST ON the PLACE the maximum working pressure can be increased by 11/2 times in comparison with the specified data. † Admissible distances between end faces of pipes and deviations designate the maximum nominal range of shift on connection of a standard pipe with the pressed flutes. Values for standard pipes with fine-molded flutes can be doubled. These are the maximum figures, for designing and installation they should be reduced on: 50% for 3/4 - 31/2"/20 - 90 mm; 25% for 4"/100 mm and more. The number of necessary screws corresponds to quantity of segments of the case. There are screws with metric sizes (a color code) for all sizes of couplings on demand. Request details from Victaulic. PREVENTION: Before installation, dismantle or adjustment of pipeline products it is necessary to reduce pressure in system and to empty it.
