Dongying Lake Petroleum Technology supplies shear ram and variable ram assemblies for blowout preventer stacks compatible with SHENKAI and RONGSHENG BOP systems. The rams are engineered to API Spec 16A and 16C standards with working pressure ratings from 2000 psi to 15000 psi (14 MPa to 105 MPa). Bore sizes span 7 1/16 inches to 21 1/4 inches, accommodating standard BOP configurations used in land and offshore drilling operations across China.
The ram bodies are forged from alloy steel grades typical for subsea and surface BOP service, heat-treated to meet API hardness and impact requirements. Operating temperature range is specified from -18 degrees Celsius to 121 degrees Celsius, covering standard drilling fluid temperatures. Top and bottom connections are available in flanged or studded configurations to match existing BOP stack geometries. Seal elastomers are typically selected for compatibility with synthetic-based muds, oil-based muds, and H2S service conditions per NACE MR0175.
These rams are used in primary well control systems for drilling contractors, oilfield service companies, and rig operators requiring replacement or upgrade of BOP sealing elements. Variable rams accommodate multiple pipe diameters without full ram block replacement, reducing rig non-productive time. Shear rams provide emergency wellbore closure capability. Buyers should confirm exact pipe size ranges, seal compound specifications, and API monogram status directly with the supplier before ordering.

Before ordering, verify that Dongying Lake Petroleum Technology holds valid API Q1 certification and current API monogram license for Spec 16A ram BOPs. Request material test reports for the specific heat lot, including chemical composition, mechanical properties, and Charpy impact values. Confirm the exact bore size, pressure class, and connection configuration match your existing BOP stack. Ask for reference installations with SHENKAI or RONGSHENG equipment, and verify the supplier's capability to deliver spare seal kits and wear parts on short notice.
Logistics from Dongying City, Shandong Province typically ship via Qingdao or Tianjin port for sea freight. Confirm Incoterms, whether the supplier quotes FOB Qingdao, CIF destination, or another term. Lead time is not stated in the source; buyers should request production schedule and whether rams are built to order or drawn from inventory. Payment terms, including advance payment percentage, letter of credit requirements, and milestone payment structure, must be negotiated directly. Clarify export licensing and customs classification under HS code 8431.49 for BOP parts.
Quality checks upon receipt should include dimensional verification of bore, flange bolt circle, and ring groove against API 16A tolerances. Inspect elastomer seals for storage damage, hardness drift, or surface cracking. Require witnessed hydrostatic testing to 1.5 times working pressure if not already performed and certified. Maintain full traceability records linking serial numbers to material certificates. For variable rams, function-test across the claimed pipe diameter range before installation on the rig.
