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.
STRAUB Couplings meet or exceed the requirements of ASTM 1476 & ISO/NP-15837/ 15838 & ANSI / AWWA C227-22 and Performance Coupling is ISO 9001:2015 compliant
Note: AIS exemption/compliance available upon request

 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 pipe diameter 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.
4. Coupling dimensions for reference purposes only.
5. The DV and X 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.
 Note: For STRAUB-GRIP and STRAUB-METAL-GRIP couplings,an additional pressure rating column is shown.
This is for applications that require authorization by Marine Approval Agencies such as Lloyds, ABS, DNV, etc.)
