THE STUDY OF UNDERWATER CONNECTOR TEMPERATURE TEST EQUIPMENT

摘要

Underwater connector as a part of the Christmas tree or underwater oil and gas pipeline, it is mainly used for wellhead manifolds connection and quick repair [1] when Connector at work, In the internal, there is high temperature and high pressure liquid, gas or vapor liquid mixture, external for the low temperature water. So the temperature performance is the core of performance, the test of temperature performance must be done [2]. This paper analyzes the ISO and API standard, it is concluded that the temperature test requirements of underwater connector, and according to the temperature test requirements, designed Temperature test device consisting of The heating unit, refrigeration unit and heat preservation unit, and the temperature test process of underwater connector has carried on the theoretical calculation and Ansys simulation, obtained reliable temperature gradient, and the temperature control difficulty in the process of temperature test are proposed.
