Bop

The 13 5/8-inch annular blowout preventer rated to 5,000 psi working pressure from Drilltech Manufacturing Co., Ltd. in Hebei, China, is built for high-pressure drilling environments where well control is critical. Forged steel construction forms the pressure-containing body, with an annular sealing element designed to close around various pipe diameters and even open hole during emergency operations. The 13 5/8-inch bore size matches standard wellhead configurations for intermediate casing programs in deep drilling.

Annular BOPs of this class typically employ a synthetic rubber elastomer reinforced with steel segments in the packing unit, allowing conformance to irregular geometries under hydraulic activation pressure. The 5,000 psi rating places this unit in the mid-high pressure tier for annular preventers, suitable for land and offshore drilling to moderate depths rather than ultra-deepwater applications. Standard industry practice requires redundant ram BOPs below the annular for full pressure isolation, with this unit serving as the primary dynamic seal during connections and tripping operations. Drilltech's forged steel specification rather than cast construction suggests attention to through-thickness properties and fatigue resistance in the pressure boundary.

Buyers include drilling contractors, oilfield service companies, and rig operators outfitting new builds or replacing worn stack components. The unit ships from Cangzhou, Hebei, a region with established metalworking and oilfield equipment manufacturing clusters. Importers should confirm API 16A compliance status, material certifications for the forged steel body, and hydrostatic test documentation before placement. Packaging typically involves wooden crating with corrosion inhibitor treatment for ocean freight.

Drilltech Manufacturing Co., Ltd. operates from Jv Guan County Zone in Xinhua, Cangzhou, Hebei Province, a northern Chinese industrial corridor with established supply chains for forged steel components and oilfield machinery. The supplier's tier is marked as imported with a harbor trust designation, indicating cross-border transaction history though not the highest verification level. The response rate shows 0.00 with zero average response hours, which suggests either a new listing profile or incomplete engagement metrics rather than active trading history.

The address places Drilltech within Cangzhou's metal fabrication zone, a region with access to Baoshan Iron & Steel supply and port logistics through Tianjin or Huanghua. No verified factory audit, ISO certification, or API license numbers appear in the source profile. The listing describes forged steel construction and 5,000 psi pressure capability but does not specify API monogram status, material test reports, or quality system accreditation. Buyers should treat claims as unaudited and request original mill certificates, welding procedure qualifications, and third-party inspection reports before contract execution.
