PRESSURE VESSEL AND PRESSURE VESSEL FOR TESTING BOP

摘要

The present invention relates to a pressure container and a pressure container for testing BOP equipment. The pressure container can store a high pressure fluid or can put BOP equipment along with a high pressure fluid in a test chamber. The pressure container and the pressure container for testing BOP equipment can reduce the size of pressure transmitted to multiple bulkheads using a pressure difference between the test chamber and a buffer chamber, by forming the buffer chamber outside an inner container using a multiple bulkhead structure having the inner container and an outer container and forming the pressure in the test chamber and the buffer chamber differently from each other, thereby maintaining a stable structure even at high pressures. In addition, the pressure container and the pressure container for testing BOP equipment can reduce the thickness of the bulkhead and can secure diversity in selecting materials.
