  INTERNATIONAL CERTIFICATION
 Some of the approvals for STRAUB couplings are shown above. STRAUB couplings are approved and listed by a large number of national and international agencies in various industries, including water engineering, fire protection, mining, shipbuilding & offshore, gas, petrochemical and general industry. Contact STRAUB for details. STRAUB is an ISO 9001 certified manufacturing facility and 14001 certified . US Patent Numbers: 5 280 969, 5 137 305, 3 877 733, 5 273 322, 4 119 333, 4 629 217, 5 280 970, 4 664 422, 5 310 223, 5 203 594.
STRAUB Couplings meet or exceed the requirements of ASTM 1476 & ISO/NP-15837/ 15838 & ANSI / AWWA C227-07

   1. STRAUB Couplings are identified by either the nominal IPS pipe size, CTS tube size, or AWWA ductile iron pipe size in inches, or the pipe/tube OD in inches and millimeters.
2. Nominal outside diameter of pipe or tube that coupling will fit.
3. Maximum line pressure, including surge, to which the pipe joint should be subjected. Note: For a one-time field test the maximum joint working pressure may be increased to 11/2 times the figure shown.
(For STRAUB-GRIP-L and STRAUB-METAL-GRIP cou- plings, an additional pressure rating column is shown. This is for applications that require authorization by Marine Approval Agencies such as Lloyds, ABS, DNV, etc.)
4. Coupling dimensions for reference purposes only. 5. The DV and KV assembled dimensions provided for
reference.
6. Maximum allowable distance between pipe ends when assembled (with or without strip inserts).
7. Required Torque Rate. This is also printed on all couplings. Torque rate is suitable for all recommended pipe materials
8. Weight of complete coupling.
