WS-Series Blowout Prevention Safety Coupling - Quick Release Couplings
- Fire tested and Lloyd’s certified to 700°C (1300°F) in accordance with API 16D (Certificate #NAO 0601041/1)
This certificate applies to the 1” size only. During the certification for the 1” size, Dixon was advised by Lloyds during the process that the 1” would set the precedence for the rest of the series and sizes.
Dixon confirm that all other sizes of WS-Series BOP Couplings (3/4”, 1-1/4”, 1-1/2”, 2”) are manufactured to the same quality and standard as the 1”. Copies of this certification are available. - Designed for hazardous area service where couplings are required to operate under fire conditions in an emergency
- Sleeve is cast using a unique process that provides better surface finishes, tighter tolerance control, and excellent repeatability
- Blowout Prevention Couplings are individually marked with the BOP series designation and manufacturing date code
