About Botou Bolu Petroleum Machinery Factory - Machined Components Supplier in China

China‑based Botou Bolu Petroleum Machinery Factory lists sixteen active products focused on mud‑pump equipment and related machined components. The catalogue includes API‑type mud pump liners, pistons, valves, triplex mud‑pump modules and assorted spare parts, with the only HS‑code provided for Mud Pump Parts (8413.91) and the material specified as high‑chrome cast steel or alloy steel grades 4140/4340. The product titles repeat across API‑designated and generic variants, such as API Mud Pump Liner, Mud Pump Valve, Triplex Mud Pump Module and Mud Pump Spare Parts, reflecting the typical nomenclature used in oil‑field equipment supply. Each entry is presented without additional technical specifications, leaving the exact dimensions, pressure ratings or flow capacities to be clarified with the supplier.

The factory’s top categories span Machined Components, Piston & Piston Rings, Agriculture, Pipe Valves and Automobile Spare Parts & Supplies, indicating a broader manufacturing capability beyond oil‑field gear. While the facts do not disclose certifications, the listed products fall under the HS‑code chapter 84 for pumps and related parts, which trade authorities commonly inspect for compliance with API standards and material certification. Buyers can therefore expect the need for material test reports, API conformity certificates and export documentation when importing these items from China.

Product Range and Specialties of Botou Bolu Petroleum Machinery Factory

The product range is concentrated on mud‑pump assemblies: liners and pistons for both standard and triplex configurations, valve bodies, and complete pump modules. In the oil‑field sector, mud‑pump liners are typically forged from high‑chrome alloy steel meeting hardness levels of 48‑54 HRC, while pistons are machined to tolerances within ±0.03 mm and often heat‑treated to achieve tensile strengths above 800 MPa. Triplex mud‑pump valves usually conform to API 16A specifications, featuring wear‑resistant sleeves and seal rings designed for continuous operation at pressures up to 350 bar. The listed material (alloy steel 4140/4340) is a common choice for these components because of its balance of strength, toughness and machinability, and buyers often request heat‑treatment certificates confirming carburizing or quenching processes.

Trade and Export Information - Botou Bolu Petroleum Machinery Factory

China is a major exporter of oil‑field equipment, and mud‑pump parts such as those listed are regularly shipped to drilling contractors in the Middle East, North Africa, Southeast Asia and South America. The HS‑code 8413.91 places these items in the “Pumps for liquid or gas” category, which customs authorities typically subject to inspection for API compliance and material certification. Typical import requirements include API 16 series certification, ISO 9001 quality‑management documentation, and, where applicable, CE marking for equipment used in EU‑linked projects. Export logistics often involve 20‑ft or 40‑ft containers packed on wooden pallets with steel strapping, or bulk shipments on open‑top containers for larger modules. Common Incoterms are FOB Shanghai or CIF Dubai, reflecting the established maritime routes from Chinese ports to oil‑producing regions.

Sourcing from Botou Bolu Petroleum Machinery Factory - Buyer Guidance

When sourcing mud‑pump components from this supplier, request a full material test report (MTR) that details chemical composition, hardness, tensile strength and heat‑treatment parameters for the high‑chrome cast steel or alloy 4140/4340. Ask for API standard certificates (e.g., API 16A for valves, API 16D for pump modules) and any ISO 9001 or CE documentation that the factory can provide. Verify the dimensional drawings against your equipment specifications, and confirm the packaging plan - typically wooden crates with internal cushioning - to ensure safe transport of heavy steel parts. A pre‑shipment sample of a liner or piston can be used to validate machining tolerances and surface finish before placing a larger order.
