The API Spherical Sealing Element is a core component for annular blowout preventers, designed with a spherical plastic core and dust-proof ring to seal wellheads under high-pressure conditions. This model operates at up to 10.5 MPa, using hydraulic pressure to move the plastic core upward along a ball surface, closing the wellhead around drilling tools or fully sealing it. The structure allows sealing of pipe strings with nominal paths from 0 to DN in various shapes, with a design that integrates smoothly with ram BOPs for enhanced performance.
Constructed with a durable plastic core, the element is engineered for long service life and adaptability across a broad selection of drilling environments. Typical industry standards for such components include temperature resistance from -30°C to 120°C, with sealing capabilities for wellbores ranging from 4 1/2 to 20 inches. The spherical design ensures even pressure distribution, reducing wear on the rubber sealing surfaces and maintaining integrity under repeated cycling.
This sealing element is primarily used in oil and gas exploration to prevent uncontrolled fluid release during drilling operations. Buyers typically include drilling contractors and oilfield service companies sourcing API-compliant equipment for onshore and offshore rigs. The unit is supplied as a direct replacement part, with compatibility confirmed by the BOP model and wellhead specifications. Lead times and packaging details should be verified with the supplier, as these depend on the specific order configuration.

Before placing an order, verify the compatibility of this spherical sealing element with your annular BOP model and wellhead specifications. Confirm the exact pressure rating, temperature range, and sealing capacity to ensure it matches your drilling conditions. Request the supplier’s technical drawings or API compliance certificates to validate the design and material specifications.
Logistics for this component should be discussed directly with Dongying Lake Petroleum Technology co.,ltd, as lead times may vary based on order volume and customization requirements. Clarify the Incoterms offered, such as FOB or CIF, and whether the supplier can arrange shipping to your designated port. Packaging standards for oilfield equipment typically include wooden crates or pallets to prevent damage during transit, but confirm the exact method with the supplier.
Quality checks should focus on the integrity of the spherical core and dust-proof ring, as these are critical to sealing performance. Inspect for uniform material thickness, absence of defects, and proper fitting within the BOP housing. Request a third-party inspection report or factory acceptance test (FAT) results if available. Ensure all documentation, including material certificates and API compliance records, is provided before shipment.
