Import Bop Vbr Rams For Sales — Buy in wholesale FOB from Supplier in China

The variable bore ram (VBR) from Dongying Lake Petroleum Technology co.,ltd is a ram-type blowout preventer designed to seal around drill pipes across a range of diameters without changing rams. This unit functions as a critical well control device during oil drilling operations, replacing multiple fixed-bore rams with a single assembly that adapts to varying pipe sizes. The source description indicates finite element modelling was used to analyse stress distribution during sealing, suggesting engineering validation of the ram's mechanical performance under pressure.

Manufactured in Dongying City, Shandong Province, this VBR employs an elastomeric sealing element that deforms under hydraulic pressure to grip tubulars of different outer diameters. Typical ram block materials for this equipment category include alloy steel forgings with HRC 28-32 hardness, meeting API 16A material specifications for wellhead and BOP equipment. The sealing rubber is typically a nitrile or hydrogenated nitrile compound rated for H2S service, though the exact compound should be confirmed with the supplier. Variable bore rams of this class typically accommodate pipe sizes from 3-1/2 inch to 5-1/2 inch in standard configurations, with working pressures commonly rated at 3,000 psi or 5,000 psi.

This equipment serves drilling contractors and oilfield service companies operating onshore and offshore rigs where rig floor space and weight are at a premium. The VBR's principal advantage is inventory reduction, a single ram assembly replaces multiple conventional rams, cutting spare parts stock and change-out time. Buyers should confirm the exact bore range, pressure rating, and API monogram status with Dongying Lake Petroleum Technology co.,ltd before procurement. The supplier's location in Dongying, a recognised oilfield equipment manufacturing cluster in China, offers access to established machining and heat treatment infrastructure.

Dongying Lake Petroleum Technology co.,ltd is headquartered at 15 Floor, Huatai Center, Dongying City, Shandong Province, China, postal code 257000. The supplier holds a 'harbor' trust tier designation on the platform, with a recorded response rate of 0.00 percent and zero average response hours, indicating no response history is available through this channel. The company operates from Dongying, a city with established oilfield equipment manufacturing infrastructure and supply chain concentration for petroleum drilling tools.

The listing description references engineering analysis through finite element modelling, which suggests some internal technical capability, though buyers should independently verify design credentials and quality management certification. No specific API licence numbers, ISO certifications, or manufacturing scope details are provided in the source data. The supplier's address places it in a commercial centre rather than an industrial zone, so buyers should confirm whether production is in-house or outsourced, and request facility audit documentation if considering volume orders.
