Product Introduction
Our CSF-1300 safety system parts are premium OEM-equivalent components designed to safeguard the pump and entire drilling rig from catastrophic overpressure events, covering the JA-3 shearing safety valve and KB75 air dome assemblies. The lineup includes precision shearing pins, pistons, airbags, pressure gauges, seal rings, valves, and standardized fastening hardware, crafted from heat-treated alloy steel, explosion-resistant elastomers, and pressure-rated industrial materials. All components meet strict API 7K and drilling pressure safety benchmarks, making them the trusted choice for safety compliance, routine safety maintenance, and emergency safety system repairs.
Functional Specifications
- Overpressure Emergency Protection: The JA-3 shearing safety valve activates automatically at pre-calibrated pressure thresholds, shearing the designated shear pin to rapidly relieve excess pressure and prevent pump or rig structural damage, with a 0-25Mpa operating range perfectly matched to CSF-1300 pump specifications.
- Hydraulic Pressure Stabilization: KB75 air dome components regulate system pressure fluctuations, absorb hydraulic shocks from pumping cycles, and maintain stable mud pressure to reduce stress on safety and fluid end parts, extending overall pump service life.
- Real-Time Pressure Monitoring: 0-25Mpa pressure gauges provide clear, accurate pressure readings, enabling technicians to detect abnormal pressure spikes before they escalate into safety hazards.
- Leak-Free Pressure Sealing: High-pressure seal rings, gaskets, and airtight joints maintain consistent pressure integrity, preventing pressure leaks that compromise safety device functionality and reliability.
- Reliable Emergency Activation: Precision-machined shearing pins, locking springs, and piston assemblies ensure consistent, predictable safety valve activation with zero false trips or failed emergency shutdowns in critical moments.
Structural Characteristics
These CSF-1300 safety system components feature a rugged, safety-optimized structural design: the JA-3 shearing valve uses a modular piston-and-shear pin assembly for quick, hassle-free replacement of worn safety parts, while the KB75 air dome incorporates a reinforced shell assembly and heavy-duty airbag for superior shock absorption. All fastening hardware (pins, nuts, washers) is pressure-rated and corrosion-resistant, with a compact, pump-integrated design that fits seamlessly into the CSF-1300’s existing safety system without modifications or reconfiguration.
Applicable Operating Conditions
These safety components are engineered to perform reliably in the harshest drilling environments: onshore deep-well oil/gas drilling, offshore platform well servicing, directional drilling, geothermal drilling, and high-pressure abrasive mud circulation operations. They tolerate extreme temperature fluctuations (-20°F to 220°F), corrosive drilling fluids, continuous high-pressure cycling, and high-vibration rig conditions, maintaining full safety functionality in remote land rigs, offshore vessels, and high-risk drilling sites worldwide.
Maintenance & Servicing Recommendations
To ensure continuous safety functionality and unbroken regulatory compliance, follow these industry-approved maintenance protocols: inspect JA-3 shearing valve components (shearing pins, pistons, springs) every 300 operating hours for wear, corrosion, or deformation, replacing worn parts immediately to preserve activation reliability; test safety valve activation pressure quarterly to verify compliance with pre-set OEM thresholds; inspect KB75 air dome airbags and seal rings every 450 hours for leaks, cracks, or degradation, replacing damaged airbags promptly to maintain pressure stabilization; calibrate 0-25Mpa pressure gauges semi-annually to ensure accurate, trustworthy readings; tighten all fastening hardware to OEM torque specifications to prevent pressure leaks; and store rubber and elastomer safety components in a dry, temperature-controlled environment to preserve material integrity and extend shelf life.

Field Failure Repair Case Studies
Case 1: Fatigued Shearing Pin Causing Safety Valve Failure
A land drilling rig experienced a sudden pressure spike on a CSF-1300 pump, with the JA-3 shearing safety valve failing to activate due to a metal-fatigued shearing pin. Replacing the OEM-grade shearing pin, locking spring, and piston assembly restored proper safety valve functionality, passing all pressure safety tests and preventing potential rig overpressure damage.
Case 2: Ruptured Airbag Degrading KB75 Air Dome Performance
An offshore service crew reported unstable pump pressure and frequent hydraulic shocks, traced to a ruptured airbag in the KB75 air dome. Installing a new airbag, R30 seal ring, and bottom plug eliminated air leaks, restoring consistent pressure stabilization and reducing stress on the pump’s fluid end components.
Case 3: Malfunctioning Pressure Gauge Leading to Unmonitored Spikes
A remote drilling rig faced an unforeseen overpressure risk due to a faulty 0-25Mpa pressure gauge that provided inaccurate readings. Replacing the gauge, cover assembly, and angle stop valve restored real-time pressure monitoring, allowing technicians to detect and resolve pressure anomalies before safety risks escalated.
