Wellhead tubing hangers are an important component of the wellhead assembly in the oil and gas industry. They are used to support and seal the tubing string that extends from the wellhead down into the wellbore.

A wellhead tubing hanger typically consists of one or more flanged components that are installed and secured onto the wellhead. The tubing is then hung from the hanger using a series of threaded connections, hanger bolts, and seals.

The primary function of a tubing hanger is to support the tubing and provide a pressure-tight seal between the tubing and the wellhead. This helps to prevent the escape of oil or gas from the well during production.

Tubing hangers also often include features that allow for the installation and operation of downhole tools and production equipment, such as electrical submersible pumps, gas-lift mandrels, or production packers.

Overall, wellhead tubing hangers play a critical role in the safe and efficient operation of oil and gas wells, and they must be carefully selected, installed, and maintained to ensure their reliability and longevity.
