Abstract: A tubing or pipe connector assembly primarily for use at cryogenic temperatures. The connector is of the screw thimble, gland type which is provided with a sealing member having a malleable metal seal partially inset in an annular groove in its radial face or faces. The sealing force for the seal is provided by spring members which are compressed when the threaded gland is screwed into the thimble. Materials used in the connector system are selected to effectively maintain the seal as temperature and pressure are cycled. The thread system of the gland and thimble and the deflection of the spring member can be selected so that after the connector components have been assembled to a fingertight condition, approximately a single turn of the gland finishes the connection operation.

Abstract translation: 主要用于低温的管道或管道连接器组件。 连接器为螺旋弹簧，压盖式，其具有密封构件，密封构件具有部分插入其径向面或环形槽中的环形槽中的可延展的金属密封件。 密封件的密封力由弹簧构件提供，弹簧构件在螺纹密封套拧入套管时被压缩。 选择连接器系统中使用的材料，以在温度和压力循环时有效地保持密封。 可以选择压盖和套管的螺纹系统以及弹簧构件的偏转，使得在将连接器组件组装到手指紧密状态之后，大约一圈的压盖完成连接操作。
