Product Description

tubing head 

Tubing head is a spool with flange top, flanged bottom and two side outlets. It also can be called tubing spool. Top flange is equipped with lock screws to fix tubing hanger. Tubing head is installed on top of casing head, which consists of body housing and tubing hanger. It can hang tubing string and seal the annular space between tubing and production casing. Our company can manufacturer tubing head with standard structure, which includes tubing hanger installed on the cone of body housing. Tubing hanger can be tapped with BPV thread as per request.

• Fabricated with BT technology seal and could be field mounted by cutting casing pipe to accommodate the seal height.
• Tubing hanger and top flange are designed to run cable through.
• Several control ports are available for connecting pipeline.
• Made of forged or special smelt steel, providing high bearing strength, safety and reliability.

A Tubing Head , also known as Tubing Head Spool or Tubing Spool, is an important mechanical fitting used on the wellhead assembly. It is usually located in the lower section of the wellhead above the casing hanger and casing spool. Tubing head features a profiled inner surface designed to accept the tubing hanger which supports and seals the tubing conduit. The upper section of the wellhead assembly is called the Christmas tree, and is attached to the top of the tubing head by means of a specially-designed head adapter. Usually, a tubing head is provided with several ports for the inclusion of gate valves and other instruments.

A wellhead is the surface termination arrangement of a subterranean crude oil well. This assembly typically consists of two multi-part sections, namely the tubing head and casing hanger section, and the Christmas tree. The hanger section is designed to support the casing and tubing strings, to terminate the wellbore during the construction phase, and to support the Christmas tree during production. The Christmas tree is a complex arrangement of valves, spools, and instruments so named because of its characteristic cluttered, crucifix shape. Its function is to control and monitor the well and its output during the production phase.

Simply put, tubing head is a wellhead component that supports the tubing hanger and provides a means of attaching the Christmas tree to the wellhead. Tubing Head Spools provided by Qihang are strictly produced in accordance with API 6A standards and can be used for both single completions and model of dual completions.
