BOPs are one of the first lines of defense in controlling an oil well. When activated, the hydraulic pressure drives the piston, which in turn closes the ball. Closing of the sphere occurs in a smooth, simultaneous upward and inward motion, rather than a horizontal motion. HRSB is a top industry Manufacturer of Annular/Spherical Blowout Preventer (BOP), please contact us if you need.
Spherical BOPs are compact annular BOPs that reliably seal kelly, drill pipe, tool joints, drill collars, casing or wireline of virtually any shape or size. The ball valve also provides positive pressure control for running drill pipe in and out of the hole. They are available in Bolt Cover, Wedge Cover, Double Wedge Cover and NXT models, which include the following special features:
Rugged, reliable sealing elements provide a reliable seal after hundreds of full working pressure tests
Rugged, simple construction; only five main parts
Compact body saves space; height is 15% to 20% lower than some other annular BOPs
Simple hydraulic system; only two hydraulic connections required
Wear rings on moving parts prevent metal-to-metal contact; this feature extends preventer life
Applies to H2S services. Standard model suitable for internal H2S service, simple bolt and lifting shackle replacement converts it to external H2S service
Easy maintenance; no need to bring mud or grit into the hydraulic system when replacing components
Steel segments reinforce the sealing element but do not protrude into the wellbore when the element is opened
