All components are designed for direct replacement, requiring no secondary modification—saving maintenance teams valuable time and reducing labor costs.

Structural Features

Our components feature practical, durability-focused designs that adapt to harsh industrial environments, based on real on-site feedback: DQ027 series structural parts (such as DQ027.23.00Ⅱ Quick Response Beam and 1200528193 Balancing Beam) use high-strength carbon steel with hot-dip galvanizing treatment, resisting corrosion in humid, salty offshore environments for 5 years; DQ027.12.20 Sealing Oil Seal uses nitrile rubber with a reinforced steel frame, increasing wear resistance by 2.8 times compared to ordinary seals; DQ026.04.00 Flushing Pipe Assembly adopts seamless steel structure (thickness 8mm), withstanding 15MPa pressure without bursting; 1300000269 O-Ring uses fluorine rubber, resisting high temperatures up to 150℃ and chemical corrosion from flushing fluids; DQ027.08.01.01.00 Motor Rain Cover has a waterproof grade of IP67, preventing water damage to motors in outdoor oilfield environments. All structural designs are tested and optimized by on-site engineers to ensure they stand up to the toughest working conditions.

Applicable Working Conditions

Our products are tailored to thrive in harsh industrial and oilfield working conditions, with clear scene anchoring to meet specific user needs: DQ027 series components (DQ027.12.20 Sealing Oil Seal, DQ027.12.01 Outer Cover) are ideal for oilfield pumping units, wellhead equipment, and heavy-duty cranes, adapting to -40℃ to 90℃ temperatures and 95% humidity; DQ026.04.00 Flushing Pipe Assembly is suitable for oilfield drilling fluid flushing systems and industrial pipeline cleaning, withstanding high-pressure fluid flow (up to 15MPa); 1300006311 Bolt and 1300013486 Bolt are used in high-vibration equipment such as oilfield compressors and conveyors; 1700145308 Seamless Steel Pipe is suitable for oil and gas transportation pipelines in oilfields, resisting corrosion and high pressure; DQ027.01.10 Piston is designed for hydraulic systems in heavy machinery, ensuring smooth operation under 10MPa pressure. All products have passed extreme environment tests, including high-temperature, low-temperature, and corrosion tests, ensuring stable performance in the most challenging on-site conditions.
