API 16A hydril annular BOP

API 16A hydril annular BOP

Use: Well Drilling
Type: Bop
Processing Type: Forging
Certification: API

Our API 16A hydril annular BOP

can be used in work over and drilling operations equipped with hydril control systems. The BOPs are designed and manufactured in full conformity to the API 16A standard. The annular BOP mainly consists of a body, a header, a rubber core, and a piston. The inner rubber core is interchangeable. While the annular BOP can be used independently, it normally works with a single or a double BOP.It can seal the drilling tool or well bore efficiently, preventing oil well blow outs. Its anti H2S performance conforms to the NACE MR 0175 standard.

Packaging Details:Packed in wooden cases, container transport
Port: Qingdao Shanghai Tianjin

Key Feature:

1.single ram BOP seals annular space between tubing and casing or wellbore.

2.single ram BOP suspends and stabilizes string.

3.single ram BOP with side outlets could be used for choke and blowout.

4.single ram BOP can be used in operation under pressure.
