The Mud Circulation Tank, a fundamental carrier that combines mud storage, circulation, and purification for drilling operations, is supplied by Shaanxi Xixian New District Zhongcheng Machinery Manufacturing. In order to achieve maximum space utilization and low leakage performance, our modular assembly structure has a zoning design with all standard Accessories. Each unit receives ISO 9001/14001/45001 certification as well as HSE, TÜV, and BV clearance. It is compatible with ZJ20 to ZJ90 drilling rigs in onshore, offshore, and truck-mounted applications. It is the structural core of your solids control system, with a robust constructed structure and safe operating criteria.
A Mud Circulation Tank functions as a high-capacity, multi-compartmented steel vessel engineered to manage drilling fluids throughout the entire drilling lifecycle. It acts as both reservoir and processing hub for your drilling mud.
The tank solves critical pain points you face daily. Uncontrolled fluid loss drains your budget. Environmental contamination from drilling waste triggers regulatory penalties. Premature wear of downstream pumps and drill bits increases operational costs.
By providing controlled environments for sedimentation, degasification, and chemical mixing, the tank maintains stable rheological properties. Your mud performs consistently from surface to downhole and back again.
Each compartment serves a distinct purpose—circulating, mixing, settling, or storing—creating a complete fluid management ecosystem on your rig floor.

Your drilling operation demands effective mud storage and continuous stirring. Our reasonable structural design provides sufficient volume to maintain stable mud performance under high circulation rates.
Each compartment optimizes fluid residence time. Solids settle where needed. Chemicals mix thoroughly. Fresh mud stays ready for immediate deployment.
High-concentration mud and corrosive media attack inferior tanks relentlessly. We construct each Mud Circulation Tank from high-quality anti-corrosion materials that resist erosion for extended service life.
The 250-300 micron coating withstands abrasive drilling fluids and mechanical vibration from mounted equipment. Surface profile inspection guarantees optimal paint adhesion before delivery.
Sediment buildup destroys mud uniformity and clogs downstream equipment. Professional stirring devices maintain constant suspension of solids throughout the system.
Sloped compartment floors combined with high-torque mud agitators prevent stratification. Your mud properties remain consistent shift after shift.
The fully sealed tank structure eliminates mud leakage at every connection point. You avoid environmental contamination and the regulatory penalties that follow.
Our 48-hour hydrostatic pressure test identifies micro-leakage before the tank reaches your site. Water tightness testing under full load pressure guarantees zero defects.
Simple installation procedures reduce your rig-up time significantly. The modular design integrates perfectly with shale shakers, desanders, desilters, centrifuges, and other solids control equipment.
Maintenance intervals extend thanks to accessible inspection points and replaceable wear components. Your operations continue with minimal downtime.
Strong mud management is necessary in high-pressure, high-temperature conditions. To manage massive amounts of synthetic-based muds under HPHT conditions, deploy our tanks in series.
Longer residence times enable efficient desilting and degassing. Your downhole equipment is shielded from entrained gas and abrasive materials.
Compact, closed-loop systems are necessary for urban utility installations. In residential areas, our Mud Circulation Tank systems effectively recycle bentonite slurry.
Minimize environmental effect while retaining the fluid characteristics necessary for successful HDD operations. Inspectors discover no infractions; neighbors see nothing.
Conventional tanks are prematurely destroyed by high thermal stress from geothermal fluids. We design customized units with thermal-resistant liners and integrated cooling systems.
Your high-temperature, high-density drilling proceeds without incident. Long-term geothermal campaigns do not compromise the integrity of the tank.
Tanks that are the right size for the circulation capacity of smaller ZJ20-ZJ40 rigs are advantageous. Mobility between wellsites is provided via truck-mounted arrangements.
Your workover workers remain productive when they can quickly set up and disassemble. Without the need for specific fabrication, the modular framework can adjust to shifting wellsite configurations.
Before the tank leaves our 6,300-square-meter production facility in Xingping City, a thorough inspection safeguards your investment.
Every crucial load-bearing weld seam is examined by Non-Destructive Testing (NDT) employing Ultrasonic (UT) or Radiographic (RT) techniques. There are no flaws in the field.
Every tank is filled for 48 hours during the Water Tightness Testing. Under full hydrostatic pressure, we keep an eye out for deformation or micro-leakage. Only passing tanks move on to coating.
Dry Film Thickness (DFT) testing confirms that the anti-corrosive coating satisfies the 250–300 micron requirement necessary for offshore settings. Inspection of the surface profile verifies ideal adherence.
Throughout its operational life, these procedures guarantee that your tank can endure mechanical vibration from attached solids control equipment and abrasive drilling fluids.
Q1: How do you calculate the optimal capacity for my drilling operation?
Calculate your wellbore volume first. Multiply by 1.5 to 2 times to ensure adequate circulation and reserve time for fluid treatment. We provide capacity recommendations based on your rig model and typical mud properties.
Q2: Can you customize tanks for arctic drilling conditions?
Yes. We integrate steam heating coils and thermal insulation layers to prevent fluid freezing in sub-zero temperatures. All components maintain functionality down to -40°C when specified.
Q3: What maintenance interval do you recommend for the internal coating?
Visual inspection every 12 months identifies wear patterns. Full coating touch-up typically occurs every 3-5 years depending on mud abrasiveness and operational intensity.
Q4: How does the design prevent sediment accumulation in compartments?
Sloped floors guide settled solids toward agitator zones. High-torque mud agitators and strategically positioned mud guns keep particles in constant suspension, preventing buildup.
Q5: Are your tanks compliant with international transport regulations?
Our modular designs follow ISO container dimensions. Heavy-duty corner castings enable standard sea and road freight logistics. We've shipped to over 30 countries without transport complications.
Q6: What happens if we need to expand capacity later?
The modular structure allows additional tank sections to connect seamlessly. You expand capacity without replacing existing equipment. We provide engineering drawings for field modifications.
Q7: Do you supply the agitators and other internal equipment?
Yes. Complete standard accessories include mud agitators, mud guns, pipelines, valves, flanges, and safety equipment. We offer one-stop solutions or supply tanks separately for your existing equipment.
