Description
The Integral Type Casing Circulating Head is a high-strength circulation accessory designed to provide stable fluid circulation during casing running and drilling operations. Built with a non-welded integral structure and equipped with a 2″ 1502 union connection, this circulating head delivers dependable performance and pressure resistance for oil and gas field applications.
Product Overview
A casing circulating head is a specialized tool used to allow drilling fluids to circulate between the surface mud system and the casing string while casing is being run into the well. Continuous circulation helps carry cuttings to the surface, stabilize wellbore pressure, and reduce drilling complications such as stuck pipe or borehole instability.
The integral type design features a one-piece body, increasing structural strength and ensuring reliable performance under higher pressure environments compared with simple joint connections.
