Rotating BOP Rubber API 16A Blowout Preventer Equipment BOP Rubber
Core
I. Description of rotating blowout preventer:
The rotary control head is a universal wellhead rotary blowout
preventer device. It seals downhole dust, mud, oil, gas, air, and
steam through the elastic deformation of the rotating rubber core
to seal drilling tools such as kelly pipes, drill collars, and
casings. and other substances, while forcing these substances to
flow out from the side outlet to ensure the safety of the wellhead
and drill floor. It can be used in pressure drilling, underbalanced
drilling and drilling operations prone to well kicks and blowouts.
II. Features:
1. Sealing high pressure and stable rotation;
2. Reliable sealing and easy replacement;
3. The rubber core relies on its own elastic deformation and well
pressure to assist in sealing to seal around the drill string.
III. Product instructions:
Please calibrate the wellhead before use. Do not use drill pipes
with stress grooves and rough wear-resistant sleeves. The outer
burrs of the drill pipe should be polished smooth and the drill
pipe should be lubricated. Otherwise, the service life of the
rubber core will be greatly shortened. When this product is used
for tripping operations with a self-sealing head, it is required to
strictly control the wellhead pressure (as low as possible) and
tripping speed, especially the speed of the drill pipe joint;
otherwise the rubber core will burst (break) or break.
It is recommended to store the rubber core in an environment with a
temperature of 0-22°C and a relative humidity of 55%-80%. It should
not be in contact with acids, alkalis, benzene, lipid organic
solvents and corrosive chemicals, and it is required to be at least
30cm from the ground and at least 1 meter from the heat source. As
long as the above conditions are met, the warranty period is two
years. If the rubber core is not properly stored, its service life
will be shortened.
