Problems solved by technology

[0002] There are many oil outlets in the Christmas tree. The existing method is that each oil outlet is connected with a flange, and each set of flanges needs a lot of bolts to fasten. Since the Christmas tree is used in the field, after wind The bolts exposed to the rain are very easy to rust, and it is very inconvenient and time-consuming to disassemble. In addition, the gaskets used between the flat flanges are also prone to misalignment, and it is not convenient to replace the gaskets after aging. Unsatisfactory use
