Oil and gas Production Wellhead Equipment
Single Composite Tree
Used on low-pressure (up to 3000 PSI) oil wells; this type of tree is in common use worldwide. A number of joints and potential leakage points make it unsuitable for high-pressure applications or for use in gas wells. Composite dual trees are also available but are not in common use.
Single Solid Block Tree
For higher-pressure applications, the valve seats and components are installed in a one-piece solid block body. Trees of this type are available up to 10,000 PSI or even higher if required.
