The ETANG Flow Coupling is a heavy-wall connector used in tubing strings, designed to minimize the internal erosive effects caused by production fluids.

　　It is typically installed above and below flow control equipment—such as small-diameter nipple profiles, expansion joints, safety valves, gauges, and gas lift mandrels—where turbulent flow is likely to occur. By reducing internal and external erosion caused by turbulent flow, the ETANG Flow Coupling effectively extends the service life of production tubing and completion equipment.
