13 Inch Mud Cross Drilling Spool 2000 Psi Casing Spool Wellhead

Product Overview

The 13-Inch Mud Cross Drilling Spool is a heavy-duty pressure control component designed for wellhead and casing spool applications under 2000 PSI working pressure. It provides multiple flow outlets for efficient mud circulation, pressure monitoring, and choke control during drilling operations. Manufactured from forged alloy steel and produced in compliance with API 6A standards, this mud cross ensures high structural integrity, reliable sealing performance, and resistance to corrosion and high stress. It is an essential component for safe and efficient well control systems in both onshore and offshore drilling environments.
