Quality Inspection Services

• Item Verification: The Quality Assurance Department checks the name, quantity, and model of incoming materials against the packing list.
• Pending Inspection Labeling: After verification, materials are stored in the pending inspection area with a clear “pending inspection” label.
• Inspection & Release: Quality inspectors examine or verify critical components and materials according to inspection specifications; only conforming items are released to inventory for use.
• Nonconforming Material Disposition: Any raw material that does not meet standards is immediately isolated, marked as nonconforming, and handled according to the nonconforming product control procedure.

Quality control during production follows the principle that “quality is built in, not merely inspected into, the product,” requiring quality to be embedded in the manufacturing process. TR Solids Control implements key process quality monitoring:

• Process Parameter Monitoring: Real-time monitoring and recording of critical parameters such as welding temperature, vibration aging duration, and assembly torque.
• Patrol Inspection: Quality inspectors conduct patrol checks on work-in-progress according to process procedures to ensure parameters remain within normal ranges, promptly identifying and correcting deviations.
• Critical Component Testing: Specialized testing of welding quality, material thickness, and dimensional accuracy for critical components such as shale shaker screen baskets and centrifuge bowls.

In frontline production – from plate cutting and welding assembly to exciter system commissioning – every step is strictly overseen by an engineering team with over a decade of industry experience. Workshop personnel meticulously control every detail, from component machining and assembly to commissioning. Skilled technicians perform seamless welding of screen baskets and use vibration aging equipment to eliminate welding stress, preventing structural deformation under long-term vibration. The screen mounting surface is precision-milled to tightly control flatness deviations, ensuring close contact between screen and shaker basket, thereby improving screening efficiency.

TR Solids Control strictly implements a 100% final inspection system. After each equipment unit is fully assembled, the quality inspection department tests it against the final inspection checklist. A certificate of conformity is issued only after the unit passes inspection, and only then may it be dispatched.

The final inspection covers the following items:

• Visual Inspection: No scratches, cracks, or deformation on surfaces; even coating without blistering, peeling, or wear; all components firmly tightened.
• Functional Testing: Exciter system commissioning, motor operation test, seal integrity check, belt tension adjustment.
• Performance Testing: Verification of key parameters: processing capacity, separation accuracy, vibration frequency.
• Trial Run Testing: Continuous trial run of solids control systems and complete equipment; comprehensive verification of all performance parameters.
• Safety Inspection: Electrical safety, guard integrity, grounding reliability.

All completed solids control equipment at Tianrui is fully assembled, motor-protected, and subjected to final inspection before being moved to the pending-shipment area, ensuring every unit is delivered in optimal condition.
