Butterfly valves (10’’, 6’’) feature a lug or wafer type design for easy installation and disassembly; the ductile iron body has good impact resistance, the 416SS stem is corrosion-resistant and wear-resistant, and the BUNA-N seat ensures reliable sealing. Full open valves (SWND-7V1) adopt an API-7 standard design with a removable insert for easy maintenance and replacement.
4. Sealing & Auxiliary Components
O-rings (160X7, 125X7, 95X5.3) adopt a circular cross-section design with precise dimensional control to ensure tight sealing under high pressure; they are made of high-quality elastomers to adapt to different temperature and pressure environments. Mud rotary hoses (GATES) feature a durable rubber layer and reinforced structure to withstand high pressure (5000 PSI WP) and abrasion, with 4’’ API male threads at both ends for easy connection. Expansion joints (6”) have easy-align galvanized steel flanged ends and a single arch design to absorb pipeline displacement and vibration, protecting the pipeline system.
Applicable Working Conditions
Our drilling rig spare parts are specially developed to adapt to the harsh and complex working environments of oilfield drilling, suitable for the following scenarios:
• Onshore Oilfield Drilling: Adapt to dry, dusty, high-temperature, and low-temperature environments (temperature range: -40℃ to 85℃), suitable for conventional oil and gas drilling, shale gas drilling, and coalbed methane drilling, with strong resistance to dust and vibration.
• High-Pressure Drilling Operations: Bear high working pressure (up to 5000PSI, 35MPa), suitable for deep well drilling, ultra-deep well drilling, and high-pressure mud circulation systems, ensuring no leakage or failure under high pressure.
• Heavy-Duty Continuous Operations: Designed for 24/7 continuous drilling operations, with high durability and reliability, reducing the frequency of part replacement and equipment downtime, and improving overall drilling efficiency.
• Corrosive & Abrasive Environments: Resist corrosion from acidic, alkaline, and high-salinity mud, and abrasion from high-solids mud, suitable for drilling in coastal, saline-alkali, and other corrosive areas, extending the service life of components.
Maintenance & Care Recommendations
Proper maintenance and care of drilling rig spare parts are crucial to extending their service life, reducing maintenance costs, and ensuring the stable operation of drilling equipment. Based on years of on-site operation experience, we provide the following practical maintenance recommendations:
1. Storage Guidelines
Store spare parts in a clean, dry, and well-ventilated warehouse, avoiding direct sunlight, rain, and humidity. Transmission components, valves, and precision parts should be stored in sealed packaging to prevent dust and moisture contamination; metal parts should be coated with anti-rust oil every 3 months to avoid rust. Spare parts should be classified and placed on shelves according to their categories and specifications, with clear labels for easy identification and retrieval. Avoid stacking heavy objects on vulnerable parts (such as O-rings, wiper seals) to prevent deformation.
2. Installation Precautions
Before installation, thoroughly clean the installation position of the equipment and the surface of the spare part to remove dust, oil, and debris—this prevents scratches and damage to the part during installation. For transmission components and bearings, apply an appropriate amount of lubricating grease (matching the working temperature and load) to reduce friction and heat generation. For sealing elements (O-rings, seal plugs), check for damage, deformation, or aging before installation; replace them immediately if any defects are found. Follow the equipment installation manual to ensure correct installation and torque adjustment, avoiding improper installation that may cause equipment failure.
3. Regular Inspection & Replacement
During drilling operations, conduct regular inspections of key spare parts: inspect high-wear parts (pistons, cylinder sleeves, tong dies, O-rings) daily; inspect transmission components, valves, and hoses weekly. Check for signs of wear, corrosion, leakage, or deformation, and record the operation status. Replace worn or damaged parts in a timely manner according to the manufacturer’s recommended service life—for example, replace O-rings every 6 months or when aging is found; replace pistons and cylinder sleeves when wear exceeds 1mm. For emergency replacement parts, conduct a pre-installation inspection to ensure compatibility and quality.
4. Lubrication & Protection
Regularly lubricate rotating components (spindles, roller shafts, gear shafts) with appropriate lubricating oil or grease, following the manufacturer’s recommendations for lubricant type and lubrication cycle. In dusty or high-temperature environments, increase the lubrication frequency and use high-temperature, dust-proof lubricants. For equipment operating in corrosive environments, clean the surface of spare parts regularly and apply anti-corrosion coatings to extend their service life. For mud rotary hoses and expansion joints, avoid excessive bending and impact to prevent damage.

On-Site Fault Maintenance Cases
Case 1: Mud Pump Piston Leakage & Efficiency Drop
Fault Phenomenon: During onshore drilling, the SDPROSPERITY drilling pump equipped with PISTON 012180493 VT1015-62L experienced severe mud leakage at the piston end, and the pump efficiency dropped by 20%, affecting drilling progress. Reason Analysis: After disassembly, it was found that the piston seal was worn and the piston surface had scratches, leading to poor sealing and mud leakage. Solution: Replace the worn piston with a new PISTON 012180493 VT1015-62L, clean the cylinder sleeve, and check the cylinder inner surface for scratches. After installation and test run, the mud pump leakage disappeared, and the efficiency returned to normal, ensuring continuous drilling operation. Key Takeaway: Regularly inspect piston wear and replace it in time to avoid reduced pump efficiency and increased maintenance costs.
Case 2: Gate Valve Sealing Failure & Pressure Loss
Fault Phenomenon: The 4’’ ODRILL gate valve (P/N J007420-2522110) in the mud circulation system had media leakage when closed, and the system pressure dropped by 15%, unable to maintain normal drilling pressure. Reason Analysis: The valve core was worn due to long-term contact with high-solids mud, and the valve seat was damaged, leading to poor sealing.Solution: Replace the worn gate valve with a new 4’’ ODRILL gate valve (P/N J007420-2522110), adjust the valve opening and closing torque, and conduct a pressure test. After maintenance, the valve sealing performance was restored, and the system pressure remained stable. Key Takeaway: For gate valves in high-abrasion environments, regularly inspect the valve core and seat, and replace the valve in time if wear is found.
Case 3: Power Tong Die Wear & Slip Failure
Fault Phenomenon: The XQ140/12A power tong equipped with XYQ12A tong dies (73-78MM) had difficulty clamping drill pipes, and the tong dies slipped during operation, unable to complete pipe making-up and breaking-out operations. Reason Analysis: The tong die surface was severely worn, and the tooth profile was flattened, reducing the friction force between the tong die and the drill pipe. Solution: Replace the worn tong dies with new XYQ12A tong dies (73-78MM), adjust the clamping force of the power tong, and test run. After replacement, the power tong could clamp the drill pipe firmly, and the slip failure was resolved, ensuring normal drilling operations. Key Takeaway: Tong dies are high-wear parts; inspect them daily and replace them in time to avoid operational safety hazards and delays.
