Composite aluminum-fiberglass epoxy pressure vessels for transportation of LNG at intermediate temperature

OSTI ID:6033835

The design of large, 6-m diameter, composite aluminum-fiber-glass epoxy pressure vessels for the transportation of liquified natural gas at intermediate temperatures is presented. The pressure vessels are designed to have an operating pressure range of up to 6.21 MPa and pressure-to-burst ratio close to two. The cylindrical pressure vessels are circumferentially reinforced with layers of high-strength fiberglass epoxy or pultruded glass polyester overwrap. The vessels are prestressed at ambient temperature with the sizing technique of autofrettage. They are designed for temperature and pressure conditions between the critical conditions of 191 K and 4.69 MPa and atmospheric conditions of 106 K and 0.1 MPa. The ultimate failure modes are leak-before-burst and are designed in the circumferential direction to prevent the possibility of an axial separation of the vessel at failure.
