Why WSI BOPs
Snap-Loc™ Seal + Inter-Locking Ram
Patentd Premier Technology
WSI's patented Snap-Loc™ seal design and new inter-locking ram provide a positive, tamper-resistant closure that traditional ram designs cannot match. Combined with pressure-balanced rams that use well pressure to assist closure, operator effort is dramatically reduced when it matters most.
Forged Alloy Steel Body
Premier T-Series and F-Series BOPs are machined from forged alloy steel - eliminating all risk of casting porosity that can cause unexpected failure under pressure. Every unit is 100% pressure tested at the factory before shipping.
- No casting porosity - forged alloy steel only on Premier series
- 100% factory pressure tested - every Premier BOP, no exceptions
- Rated to -50°F for cold climate operations (Premier series)
- Standard NACE MR-01-75 for sour gas environments
