Import Bop Blowout Preventer — Buy in Bulk from Supplier in China

The annular blowout preventer from Weihai Vettev Equipment Co., Ltd. is a pressure-sealing device designed for oil and gas drilling operations. It forms a seal around various pipe diameters and the open hole when no pipe is present, using a reinforced elastomeric packing element. The unit is engineered for high-pressure environments typical of offshore and onshore drilling rigs, with a working pressure rating that buyers should confirm directly with the supplier. The annular design allows for rapid closure without matching specific pipe sizes, distinguishing it from ram-type BOPs in operational flexibility.

Construction utilises forged or cast steel alloy bodies with nitrile or HNBR rubber packing elements, materials standard for annular BOPs in API-controlled applications. The packing unit is hydraulically actuated, with closing ratios typically ranging from 7:1 to 10:1 depending on bore size and pressure class. Standard bore sizes in the industry span 7 1/16 inch to 21 1/4 inch, with pressure ratings from 2,000 psi to 10,000 psi (API 16A classifications). The Weihai Vettev listing does not specify exact material grades or pressure ratings, so buyers should request API 16A compliance documentation and material certificates before procurement.

Drilling contractors and oilfield service companies operating in high-pressure formations purchase annular BOPs as primary well control barriers. Applications include land drilling, platform drilling, and workover operations where hydrocarbon kicks pose operational risk. The Shandong province manufacturing base, where Weihai Vettev is located, hosts several oilfield equipment clusters with access to Qingdao port for export. Buyers should confirm minimum order quantities, lead times, and whether the unit ships as complete assembly or requires field assembly of the packing element.

Weihai Vettev Equipment Co., Ltd. is headquartered at No.98 Qingdao Road, Weihai, Shandong Province, China (postal code 264200), a coastal city with established marine and industrial manufacturing infrastructure. The company is classified as an imported supplier tier with a harbor trust designation, indicating it sources certain components or materials from overseas rather than manufacturing entirely in-house. The response rate is recorded at 0.00 percent with zero average response hours, which signals that prospective buyers should not rely on rapid email communication and should plan for direct outreach or third-party verification before committing to orders.

The supplier profile does not disclose establishment year, employee headcount, annual revenue, client roster, or factory audit certifications. No API monogram license number, ISO quality certification, or specific welding procedure qualifications are stated in the available data. Buyers should conduct independent due diligence through API registry verification, request factory inspection reports, and confirm quality management system certificates before advancing to contract. The Shandong location offers proximity to Qingdao port, a logistical advantage for breakbulk or containerised oilfield equipment shipments, though freight terms and export licencing remain to be negotiated directly with Weihai Vettev.
