In the oil and gas industry, every operation relies on three core things: efficiency, safety, and long-term reliability. Every drilling site and oil field has unique geological and environmental conditions, bringing different operational challenges. To tackle these issues, you need durable, high-standard oilfield gear that works stably even under extreme pressure.
Dongying Baosia Petroleum Technology is a trusted global supplier of premium oilfield equipment. We provide a full lineup of standard drilling tools, handling tools, and fluid control parts. What sets us apart is our flexible customization service — we tailor every piece of equipment to match your exact technical needs. No matter your required size, load capacity, or pressure rating, we deliver practical, job-specific solutions to keep your drilling and production work running smoothly.
Below is a clear breakdown of our main oilfield equipment product lines.
- Hydraulic Power Tongs (ZQ Series)
Hydraulic power tongs are essential for drilling and well maintenance work, used to fasten and loosen drill pipes, casings, and tubings on site. Our popular ZQ Series Hydraulic Power Tongs are built for high torque, safe operation, and minimal wear on your pipes. Equipped with a multi-speed gear system, our tongs let operators switch freely between high-speed low-torque and low-speed high-torque modes to fit different working scenarios. We offer multiple standard models to cover various pipe sizes and torque demands:
- ZQ127-25: Fits drill pipes, casings and oil pipes from 65 mm to 127 mm (2.375" to 3.5"). Features a high-gear max torque of 2.4 to 3 kN.m and a low-gear max torque of 16 kN.m (11,800 ft.lbf).
- ZQ162-50: Ideal for medium-duty jobs. Handles drill pipes of 85 mm to 162 mm (2.375" to 5"), casings of 114.3 mm to 153.7 mm (4.5" to 5.5"), and oil pipes of 138 mm to 156 mm (3.5" to 4.5"), with a low-gear max torque of 20 kN.m.
- ZQ203-100: Designed for heavy-duty drilling. Covers drill pipes from 114 mm to 203 mm (2.875" to 8"), with a powerful low-gear max torque of 35 kN.m to loosen tight pipe connections effortlessly.
- ZQ203-125: Our strongest model, suitable for pipes up to 203 mm (8"). It delivers a low-gear max torque of 50 kN.m (36,880 ft.lbf), easily handling the toughest pipe string disassembly work.
All our power tongs come with an integrated air pressure control system (0.5 to 0.9 MPa / 72 to 130 psi), ensuring smooth gear shifts and stable, firm clamping on the rig floor.
- High-Performance Drill Pipe Slips (SDS, SDML, SDXL)
Rotary slips are key tools to hold drill strings steadily on the rotary table during pipe tripping operations. Our premium drill pipe slips are made of heat-treated alloy steel, boasting solid structure and strong resistance to heavy axial loads for long-lasting use. We have three types of slips to match different well depths and load requirements, making it easy for you to pick the right one for your project:
- SDS (Short Slips): Perfect for shallow wells and light-weight drill strings.
- SDML (Medium Slips): Balanced in length and load capacity, ideal for medium-depth drilling projects.
- SDXL (Extra Long Slips): Built exclusively for deep and ultra-deep wells. The longer contact area effectively prevents pipe deformation under heavy loads.
Our slips fit standard pipe outer diameters including 3.5" (88.9 mm), 4.5" (114.3 mm) and 5" (127 mm). Every set is precisely calibrated in weight, easy for on-site workers to operate manually while maintaining reliable gripping force.
- Rig Floor Latch Lug Jaws
Safe and reliable locking mechanisms are critical for casing and completion work, effectively preventing pipe dropping accidents. We supply high-precision latch lug jaws with complete size options to meet diverse construction needs:
- 5a, 5b, 5b1 Series: Fits pipe outer diameters from 3.375" (85.7 mm) to 8" (203.2 mm), with a rated torque of 55 kN.m to 75 kN.m based on specific models.
- 5c, 5d Series: Suitable for large structural casings, covering sizes from 6.625" (168.3 mm) to 10.75" (273 mm).
- 5e, 5e1, 5e3 Series: Made for heavy-duty surface casing projects, supporting pipe sizes from 10.75" (273 mm) to 13.375" (339.7 mm) with a stable rated torque of 55 kN.m.
- Mud Pump Fluid End Components & Spare Parts
The mud pump is the core of the drilling fluid circulation system. Harsh working conditions like high sand content and corrosive mud can easily wear out ordinary parts. Our industrial-grade mud pump accessories effectively extend your equipment’s service life and reduce on-site downtime:
- Chrome-Iron Mud Pump Liners: Made with a high-chrome alloy inner sleeve centrifugally cast into a forged steel outer shell. The ultra-smooth inner bore resists abrasion and chemical corrosion from drilling mud, delivering outstanding durability.
- Pistons and Valves: Our premium polyurethane pistons and high-pressure valve assemblies lower friction loss, ensure stable fluid delivery, and cut down frequent equipment maintenance.
- Downhole Completion Tools
High-quality casing cementing determines the long-term stability of an oil well. Our durable downhole completion tools guarantee a perfect cementing effect for your projects:
- Casing Centralizers: We provide bow spring and solid rigid centralizers. They deliver strong resetting force to keep casings centered in the wellbore, ensuring even cement coverage around the pipe.
- Cross Coupling Cable Protectors: Designed to protect control lines, ESP cables and chemical injection lines at casing couplings, avoiding mechanical damage during installation and operation.
- Production Packers: High-performance isolation tools that seal the gap between casings and tubings, protecting casings from reservoir pressure and corrosive fluids.
