2.SAE Flange clamps dimensionsis according to ISO 6162-1:2012. ISO Nominal Size: DN 13; DN 19; DN 25; DN 32; DN 38; DN 51; DN 64; DN 76; DN 89; DN 102; DN 127; Inch size: 1/2";3/4";1";1 1/4";1 1/2";2";2 1/2";3".

 

3.Material of SAE one-piece flange clamp is made of carbon steel C45. Stainless steel.  

 

4.The external surface Corrosion protectionof all carbon steel flange clamps,shall be protected with an appropriate coating to pass a minimum 72-h salt spray test in accordance with ISO 9227.

 

5.Test requirement for pressure/temperature: Flange type connections conforming to this

part of ISO 6162 shall be subjected to the burst and cyclic endurance tests specified in ISO

19879 to verify that they meet the specified pressure/temperature requirements.

It shall be suitable for use at the working pressures given in Tables 2 when used at

temperatures between -40 °C and +120 °C. Flange connections conforming to this part

of ISO 6162 shall not be assembled at temperatures lower than -20 °C.

    WARNING——It is important that all screws be lightly torqued before applying the final recommended torque values to avoid breaking the split 

    flange clamps or one-piece flange clamps during installation (see Annex A for assembly guidelines).         

      

    a    See definition in ISO 5598.

 

    b    O-ring size code in accordance with ISO 3601-1;see Annex B for reference dimensions.

                                              

    c    ANS/ASME B18.22.1 Type B narrow washers of HV 300 quality material sized for the corresponding inch screw specified in Table 2 may be substituted for all

    but the DN 25 size, where a 7/16 washer in accordance with ANSI/ASME B18.22.1 might cause interference.

    

    d    Coarse pitch thread in accordance with ISO 261 and ISO 724.

    

    e    Screw lengths are calculated for steel;use of other materials can require different screw lengths.

 

     f     These torque values are only a guide when using lubricated screws, calculated with a coefficient of friction of 0,17. Net tightening torque depends on many

    factors, including lubrication, coating and surface finish.
