In early August, a Sinopec customer urgently requested the supply of choke manifold control cabinets due to adjustments to their on-site operation schedule. Well control equipment allows no delays-earlier equipment arrival means earlier spudding for the drilling crew.
Faced with the tight delivery deadline, the company activated its emergency order response mechanism: engineering, procurement, production, and quality inspection operated in parallel with seamless workflow handover. All manufacturing, commissioning, and factory acceptance tests were completed within an ultra-short lead time, and 5 units of choke manifold control cabinets were loaded and dispatched on August 4.
Not Just an Ordinary Cabinet
To the untrained eye, this is merely a "control cabinet"; to industry professionals, it serves as the nerve center of the drilling well control system. The technical specifications of this batch of equipment represent a truly high-end configuration in the industry:
Pneumatic-Hydraulic Remote Control: Driven by clean compressed air at 0.6–0.8 MPa to actuate the hydraulic system, remotely controlling the opening and closing of two orifice-type hydraulic choke valves for precise bottomhole pressure regulation.
105 MPa (15,000 psi) Pressure Monitoring: Real-time monitoring of standpipe pressure, casing pressure, and kill mud pressure. Piston-type sensors use hydraulic oil as the transmission medium, equipped with FIG 1502 high-pressure union connections, featuring a 4:1 input-output ratio, pressure display accuracy of 0.5 class, and a minimum scale division of 50 psi.
High-Torque Orifice Valve Actuation: Actuator output torque of 150 kgf·m, full-stroke actuation from 0° to 180°, with a built-in pneumatic valve position transmitter for real-time valve position feedback.
Multi-Layer Safety Protection: Accumulator for pressure stabilization and energy storage, relief valve for overpressure prevention, hand pump for emergency operation, and speed control valve to regulate valve actuation speed. Failure of a single air supply source will not result in loss of control.
Exquisite Craftsmanship in Details: 316 stainless steel cabinet, piping, and oil tank; shock-resistant pressure gauges with dual MPa/psi scales; foolproof quick connectors to prevent misconnection; permanent SWL lifting markings for rated load; bilingual (Chinese-English) stainless steel nameplates for the entire system.
Stringent Standards as a Baseline: Designed and manufactured in compliance with API Spec 16C Choke and Kill Systems and SY/T 5053.2-2020 Well Control Equipment Control Systems. Complete documentation is provided in accordance with API monogram product requirements.
Such a specification list tests not assembly speed, but in-depth understanding of well control processes. Delivering high-end configurations as standard products and fulfilling urgent orders with guaranteed quality reflects Xin Yulin's profound expertise accumulated over years in the choke manifold control cabinet sector.
Prioritizing customer urgencies is a commitment; fulfilling urgent orders reliably is a demonstration of strength.
