High Quality Oil Well Drilling Equipment Type S API 16A Spherical BOP
Feature
Rugged, reliable sealing element provides positive seal after hundreds of tests to full working pressure.
Strong, simple construction — only five major parts.
Compact body saves space. Height is 15 to 20% less than height of some other annular BOP.
Simple hydraulic system. Only two hydraulic connections are needed.
Wear rings on moving parts prevent metal- to-metal contact. This feature prolongs preventer life.
Servicing is easy. Element can be changed without getting mud or grit into the hydraulic system.
Steel segments reinforce sealing element but do not protrude into well bore when element is open.
Element design provides long stripping life.
Our OEM Packing element is interchangeable with Rongsheng.
Description
The Annular Blowout Preventer (BOP) is one of the first lines of defense in controlling a well. When actuated, hydraulic pressure operates the piston, and in turn closes the packing element. The closure occurs in a smooth, simultaneous upward and inward motion, as opposed to horizontal motion.
Our Annular blowout preventers are compact BOPs which seal reliably on almost any shape or size — Kelly, drill pipe, tool joints, drill collars, casing or wireline. It also provide positive pressure control for stripping drill pipe into and out of the hole.
