1. Description
The series Christmas trees have successfully resolved the critical technical issue of replacing production gate valves and casing gate valves under high pressure, and greatly reduced the valve replacement hazards and cost. No well-killing is needed and the well output will not reduce. The tree, installed at one time, can meet the requirements of pre-production high pressure fracturing and acid treating, as well as the requirements of gas production process.
Developed under API SPEC 6A, 19th edition.
