1 Scope

This section GB/T 21412 specifies the underwater wellhead, mud line wellhead equipment, drill through the mud line and underwater wellhead vertical and horizontal Specification-tree, as well as equipment handling, testing and related tools required for installation. Also it provides for an independent sub-assembly (used to build complete Subsea tree assembly) and a complete subsea tree assembly design, materials, welding, quality control (including factory acceptance test), marking, storage Store and transport. Users are responsible for ensuring the underwater equipment to meet any additional requirements to install their respective national government regulations. This is not the scope of this part within. When applicable, this section can also be applied to satellite wells, cluster wells and for a multilayer disc based completions and other aspects of the device. This section applies to the following devices. a) subsea tree --- Tree connector means and the tubing hanger; --- Valves, manifolds and valve actuators; --- Throttle valve and the throttle valve drive; --- Discharge valve, test and isolation valves; --- TFLY shaped Stone; --- Reentry interfaces; --- Christmas tree cap; --- Christmas tree line; --- Christmas tree guide frame; --- Christmas tree running tool; --- Christmas tree cap running tool; --- Christmas tree flowlines or umbilicals installation connecting means; --- Tubing head and tubing head attachment; --- Flowlines base and into the recovery tool; --- Control device interface Christmas tree installed (instruments, sensors, hydraulic tube or pipe fittings, electrical control equipment cables and accessories); b) underwater wellhead --- Catheter tip; --- Wellhead; --- Casing hanger; --- Seal assembly; --- Guide base; --- Holes and wear protection liner; --- Corrosion cap; c) mud line suspension system ......
