Manual Single Ram Oil Testing BOP |
Compared with other BOP of same sizes and pressure rating, it features simple structure, reliable performance, convenient use and maintenance, small volume and light weight . Besides, it can seal various kinds of tubing, small drill pipe, cable and wireline after changing sealing rams of different size.
Model SFZ oil testing BOP has manual drive and hydraulic drive in terms of ram drive mode and has single ram, dual ram and tri-ram in terms of ram drive mode and has single ram, dual ram and tri-ram in terms of ram number. The hydraulic BOP needs to be fitted with hand pump (or BOP control device) and high pressure hose assembly. |
