– Sleeve-type throttling design- Smooth, erosion-resistant operation- Adjustable under pressure- API 6A certified- Resistant to cavitation
– High-pressure production wells- Gas injection systems- Flow control in HPHT fields- Offshore wellhead systems
Kriloha Ltd. supplies the External Sleeve Control Choke (Model-ES), designed for precise, stable flow regulation in oil and gas wells. Unlike needle-type chokes, the external sleeve choke utilizes a sliding sleeve mechanism that adjusts flow area under pressure, providing smoother and more erosion-resistant performance. The choke body and sleeve are manufactured from hardfaced alloys, designed to resist erosion, cavitation, and vibration common in HPHT service. Its design allows operators to adjust flow without shutting down operations, providing flexibility and operational efficiency. Applications include production flow regulation, gas injection control, HPHT well management, and offshore wellheads, where steady and erosion-resistant performance is essential. At Kriloha Ltd., each choke undergoes flow coefficient testing, pressure cycling, and erosion analysis, ensuring compliance with API 6A. As a supplier and facilitator, Kriloha Ltd. provides integration support, material customization, and lifecycle servicing, making the Model-ES choke a reliable and field-proven solution for flow control.
