Detailed description

*Spherical blowout preventers are compact, annular type BOPS which seal reliably on almost any shapeor size – kellys, drill pipe, tool joints, drill collars, casing or wireline. Sphericals also provide positive pressurecontrol for stripping drill pipe into and out of the hole, They are available in bolted cover, wedge cover models.*There are also special lightweight models for airlifting and Arctic models for low temperature service.SPECIAL FEATURES — SANYI SPHERICAL BOPS

Rugged, reliable sealing element provides positive seal after hundreds of tests to full working pressureStrong, simple construction — only five major parts.Compact body saves space. Height is 15 to20% less than height of some other annular BOPS.Simple hydraulic system. Only two hydraulic Connections are needed.Wear rings on moving parts prevent metal-to- metal contact. This feature prolongs preventer life.Suitable for H2S service. Standard models are suitable for internal H2S service, and simple boltAnd lifting shackle changes convert them for external H2S service.Special lightweight models can be carried by helicopter.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.

USAGE:

•Annular blowout preventer uses and hydraulic control systems supporting the use of, when within the well drilling tool, can close the different sizes of the annular space; when the wells without drilling tool, can fully closed wellhead.
