Quick-latch casing circulating head

The Quick-Latch Casing Circulating Head is a specialized circulating tool designed to facilitate fluid circulation during casing running operations in oil and gas drilling projects. It integrates a quick-latch sub that enables rapid and flexible connection to different types of casing couplings without being limited by thread type, providing efficient connection and circulation performance.

Product Overview

A casing circulating head is a vital surface circulation accessory used in drilling and casing running procedures. It is installed between the surface mud circulation system and the casing string to allow drilling fluids to circulate, helping clean the borehole, carry cuttings to the surface, and maintain pressure control.

The quick-latch sub included in this model enables faster installation and removal, adapting to various casing connection types without traditional thread limitations. This feature improves operational efficiency and reduces rig time.

Key Features & Advantages

• Quick-Latch Sub Design
  The quick-latch sub allows the circulating head to be rapidly connected to different casing couplings without being restricted by specific casing thread types, simplifying field operations and reducing connection time.

• Fluid Circulation Efficiency
  Facilitates stable fluid circulation between the mud system and casing while running casing, helping improve hole cleaning and reduce stuck pipe risks.

• Wide Size Support
  Available in standard casing sizes from 5-1/2″ up to 20″, meeting typical oilfield casing requirements.

• Standard Union Connection
  Equipped with 2″ 1502 union top connection for easy integration with surface mud system hoses and manifolds.

• Multiple Thread Compatibility
  Supports multiple thread standards (STC / LTC / BTC) at the bottom connection to suit various casing configurations.
