Shaanxi Xixian New Area Zhongcheng Machinery Manufacturing Co., Ltd. delivers high-performance Stuffing Box Clamp Plate solutions engineered for oilfield solid control and drilling equipment stabilization. Our precision-machined fastening Accessories feature split-ring structure design with uniform force bearing, specifically optimized for heavy-duty and vibration working conditions. Manufactured from high-grade alloy steel with tensile strength exceeding 60,000 PSI and dimensional tolerances within ±0.005 inches, our plates meet ISO 9001/14001/45001 standards. With over 30 years of manufacturing expertise and an annual production capacity of 200+ equipment sets across our 6,300 square meter facility, we provide stable clamping force that effectively prevents loosening and displacement in harsh drilling environments.
This clamp plate serves as a critical mechanical fastening component in oil and gas extraction systems. It secures the stuffing box assembly to pumping units and wellhead casings, maintaining polished rod alignment while ensuring pressure seal integrity.
This component addresses key operational challenges you face daily. Excessive vibration causes premature packing wear. Misalignment leads to hazardous leaks. High-pressure reciprocating loads create structural failures.
By providing a stable, rigid mounting platform, our clamp plates prevent environmental contamination. They significantly reduce your non-productive time caused by frequent seal replacements. Your operation stays efficient and compliant.
Our products combines precision engineering with robust material science. Each component undergoes strict quality control to ensure consistent performance.

High-Strength Load-Bearing Performance
Our Stuffing Box Clamp Plate utilize high-quality steel with thick, stable construction. This effectively fixes solid control equipment and prevents loosening during operation. Your wellhead assembly remains secure under continuous reciprocating motion.
Superior Wear & Corrosion Resistance
Professional surface treatment protects against mud erosion and acid-base corrosion. Our plates perform reliably in harsh downhole and wellsite conditions. You get extended service life even in H2S-rich environments.
Firm and Reliable Fixation
Engineered to match equipment and pipeline dimensions precisely. Uniform force distribution eliminates the loose fixation problems of traditional pressure plates. Your operational safety improves significantly.
Easy Installation & Maintenance
Simple structure compatible with both bolt and welding installation methods. No complex tools required. You can complete quick installation and replacement, improving operational efficiency and reducing downtime.
Non-Deformable Structure
High-temperature forging process creates compact structure with strong compression resistance. The component maintains shape stability under long-term load. Your maintenance costs decrease substantially.
Onshore Sucker Rod Pumping Systems
In standard beam pump applications, our plates anchor the stuffing box to the wellhead. They manage vertical loads from the rod string while resisting lateral forces. High-stroke-per-minute environments demand this level of reliability.
Offshore Marine Wellhead Installations
Harsh marine environments with saltwater corrosion require specialized materials. Our stainless steel variants provide necessary oxidation resistance. Remote monitoring systems rely on this structural stability for continuous operation.
High-Pressure Fluid Injection Operations
Secondary recovery operations involving CO2 or water injection create fluctuating pressure conditions. Our clamp plates ensure leak-proof seals that prevent hazardous fluid discharge. System pressure integrity remains intact throughout your operation.
Solid Control Equipment Fixation
Pressure plate support for desilter and desander components requires precise engineering. Our products prevent lifting and vibration in wellsite blowout line installations. Both onshore and offshore drilling platforms benefit from this secure fixation.
Drilling Filter Press Applications
Mud purification equipment connectors need stable mounting platforms. Our clamp plates provide the necessary support for drilling filter press systems. Your solids control efficiency improves with reduced equipment movement.
We understand that your drilling operations have unique requirements. Our engineering team provides comprehensive customization services tailored to your specifications.
Flexible Specification Options
Complete range of specifications available. We customize according to equipment models and pipeline sizes. Your installation and fixation needs receive perfect matching solutions.
Fast Delivery Timeline
In-stock standard models ship within 3 days. Customized orders deliver within 15 days. Sufficient inventory of products compatible with mainstream solid control equipment ensures you never face supply delays.
Competitive Factory-Direct Pricing
No middleman markup means strong purchasing advantages for you. Large-volume orders receive special discounts. Long-term partners enjoy priority supply and additional price benefits.
Complete Technical Support Package
Dedicated sales engineers provide one-on-one service from inquiry to installation. You receive engineering drawings, component diagrams, and operation manuals. Our professional service team delivers complete project solutions.
Quality Assurance
Material test reports available for international procurement compliance. All products meet API and ISO standards. Drilling safety requirements are fully satisfied with our comprehensive certifications.
Q: Can the clamp plate accommodate different rod sizes?
A: Yes, while the plate itself follows standardized dimensions, it's designed to work with various stuffing box housings. These housings are tailored to specific polished rod diameters, ensuring compatibility across your equipment range.
Q: What are the warning signs of a failing clamp plate?
A: Watch for visible stress fractures around bolt holes. Surface pitting from corrosion indicates material degradation. Uneven wear on the polished rod suggests plate misalignment requiring immediate attention.
Q: Does your product meet NACE MR0175 standards?
A: Our premium clamp plates comply with NACE MR0175/ISO 15156 standards. They're specifically manufactured for use in sour oilfield environments containing hydrogen sulfide.
Q: What torque specifications should I follow during installation?
A: Torque values depend on bolt grade and size. Generally, follow a cross-pattern tightening sequence to the manufacturer's specified foot-pounds. This ensures even load distribution across the mounting surface.
Q: How often should I inspect the clamp plate?
A: Perform visual inspection during every packing change. Schedule full NDT inspection every 24 months of continuous operation. Harsh operating conditions may require more frequent inspection intervals.
Q: Are replacement parts readily available?
A: Yes, we maintain sufficient stock of standard components. Replacement parts ship quickly with our efficient logistics network. Fast response for repairs minimizes your downtime losses.
Your investment deserves comprehensive protection. We provide one-year warranty coverage on all clamp plates. Lifetime technical support ensures your equipment maintains peak performance.
Our service team responds quickly to repair requests and replacement part needs. Industry training and technical guidance help your personnel maximize equipment efficiency. You reduce downtime losses through our proactive support approach.
Strong partnerships with logistics providers ensure smooth delivery. Convenient access to Tianjin and Shanghai ports facilitates international shipping. Your orders arrive on schedule, every time.
