Detailed Description

Product Overview

The Inside Blow Out Preventer (IBOP) Valve, also called Gray Valve, is a heavy-duty check valve connected to the drill string, designed for wellhead blowout prevention to mitigate surface kicks. It can remain in the drill string long-term to restore well control by establishing over-balanced pressure .

Manufactured under stringent standards ( API 7-1 or NS1 latest edition ), the IBOP Valve ensures reliability and safety in harsh conditions. Available in Standard and H₂S Resistant versions, both comply with Class 1 Construction standards to meet diverse operational needs.

Applications

The IBOP Valve(Gray Valve) is critical for safety in onshore/offshore oil and gas drilling platforms . During drilling, it rapidly responds to formation fluid influx (kicks), closing immediately to prevent uncontrolled flow and buying time for well control operations. It is indispensable in high-pressure wells , deepwater drilling , and sour gas environments (H₂S-containing formations), safeguarding personnel, equipment, and the environment across vertical, directional, and horizontal wells.

Product Features

1. High Working Pressure. Rated for 10,000 or 15,000 PSI , capable of withstanding extreme downhole pressures. Tested at 15,000/22,500 PSI to verify reliability under ultimate conditions.

2. Versatile Thread Adaptability. IBOP Valve(Gray Valve) compatible with all API-standard connections and proprietary threads from licensed vendors/OEMs. Ensures seamless integration into diverse drill string systems.

3. Rigorous Manufacturing Standards. Produced per API 7-1/NS1 specifications, adhering to global oil/gas quality/safety norms. Strict material selection, processing, and inspection ensure peak performance.

4. Dual-Version Options.

• Standard Version : For conventional drilling.

• H₂S Resistant Version : Features corrosion-resistant materials/seals for sour environments, extending service life and reducing maintenance.
