Product Description API 16A Annular Blowout Preventer (BOP) Product Description Function: An annular BOP is a critical valve at the top of a BOP stack, designed to seal the annular space (the gap between the drill pipe and wellbore or casing), enabling pressure control and preventing blowouts in drilling operations. It features an elastomeric "donut-shaped" packing element that closes inward to seal around tools or open holes.Design & Operation: It consists of a housing, a piston, and a reinforced rubber sealing element. When hydraulic pressure is applied, the packing unit constricts inward, creating a reliable seal and allowing stripping of drill pipes under pressure.JIELINVersatility: Unlike ram BOPs, an annular BOP can seal around various shapes and sizes-including drill pipe, casing, open hole, kelly, tool joints, and wireline-making it the most adaptable BOP type.Drilling ManualCAMTOP Standards Compliance: Designed and manufactured according to API Specification 16A, suitable for H2S environments in compliance with NACE MR 0175. Product ParametersPressure Rating: From approximately 2,000 psi to 15,000 psi, depending on model.MachinetoJinxiu Petroleum MachineryBore Sizes: Common sizes range from 7-1/16″ up to 21-1/4″.MachinetoJinxiu Petroleum MachineryConstruction Types:Spherical core: Typically simpler with fewer parts (about five), easy to maintain.Tapered core: Includes additional components like wear plates and support cylinders, enhancing longevity.

Product AdvantagesHigh Reliability with Minimal Parts: Often comprises just the housing, piston, and packing element, enhancing reliability and simplifyingVersatile Sealing & Stripping Capability: Capable of sealing around various tubulars and through the open hole, even while rotating, offering unmatched adaptability and operational safety.Drilling Manual JIELINCompact and Space-Efficient: Spherical designs are typically 15-20% shorter than other annular BOPs, optimizing deck space on the rig.Low Operating Pressure: Certain models operate at lower activation pressures (e.g., 1,500 psi), reducing hydraulic system complexity.Wear Protection: Equipped with wear rings and dust-proof shields to protect seals and prolong element life. Company StrengthsAPI-Certified Manufacturing: Built to API 16A and NACE MR0175 standards for high-pressure, H2S applications.Strong Material & Design Expertise: Using advanced elastomeric compounds, reinforced packing with metal frames, and providing both spherical and tapered core options.GPEGoldenman PetroleumGlobal Availability & Service: Designed with modular elements and international parts support, ensuring parts availability and serviceability.After-Sales Support: Offers inspection, replacement packing kits, and responsive technical support tailored to field operations.R&D capabilities and all-in-one solutions 56 countries - Supplier of world-renowned drilling companies 50+ Years - Experience in drilling rig equipment of our cooperative partner.
