Product Introduction

Our CSF-1600 safety device parts are premium OEM-equivalent components designed to safeguard the pump and 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 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 standards, making them the trusted choice for safety compliance, routine safety maintenance, and emergency safety system repairs.
Functional Specifications
- Overpressure Protection: The JA-3 shearing safety valve activates automatically at pre-set pressure thresholds, shearing the designated pin to relieve excess pressure and prevent pump or rig damage, with a 0-25Mpa operating range matching CSF-1600 pump specifications.
- Pressure Stabilization: KB75 air dome components regulate system pressure fluctuations, absorbing hydraulic shocks and maintaining stable pumping pressure to reduce stress on safety and fluid end parts.
- Visual Pressure Monitoring: 0-25Mpa pressure gauges provide real-time pressure readings, enabling technicians to detect abnormal pressure spikes before safety hazards occur.
- Leak-Free Sealing: High-pressure seal rings and gaskets maintain airtight/pressure-tight integrity, preventing pressure leaks that compromise safety device functionality.
- Reliable Emergency Activation: Precision shearing pins, locking springs, and piston assemblies ensure consistent, predictable safety valve activation with zero false trips or failed shutdowns.
Structural Characteristics
These CSF-1600 safety device components feature a rugged, safety-optimized structural design: the JA-3 shearing valve uses a modular piston-and-shear pin assembly for quick replacement of worn safety parts, while the KB75 air dome incorporates a reinforced shell assembly and durable airbag for 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-1600’s existing safety system without modifications.
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 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; test safety valve activation pressure quarterly to verify compliance with pre-set thresholds; inspect KB75 air dome airbags and seal rings every 450 hours for leaks or degradation, replacing damaged airbags promptly; calibrate 0-25Mpa pressure gauges semi-annually to ensure accurate readings; tighten all fastening hardware to OEM torque specifications to prevent pressure leaks; and store safety components in a dry, temperature-controlled environment to preserve material integrity.

Field Failure Repair Case Studies
Case 1: Worn Shearing Pin Causing Failed Safety Valve Activation
A land drilling rig experienced a pressure spike on a CSF-1600 pump, with the JA-3 shearing safety valve failing to activate due to a 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 damage.
Case 2: Leaking Airbag Degrading KB75 Air Dome Performance
An offshore service crew reported unstable pump pressure and frequent pressure fluctuations, traced to a ruptured airbag in the KB75 air dome. Installing a new airbag, seal ring R30, and bottom plug eliminated air leaks, restoring pressure stabilization and reducing hydraulic shock to the pump system.
Case 3: Faulty Pressure Gauge Leading to Unmonitored Pressure Spikes
A remote drilling rig faced an unforeseen overpressure event due to a malfunctioning 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 address pressure anomalies before safety risks escalated.
