Insulator apparatus for vacuum insulated tubing

摘要

An insulating apparatus for use with vacuum insulated tubing sting to reduce heat loss through the joints, where the apparatus includes an insulator adapted to surround the joint and a latching joint protector adapted to surround the insulator and hold the insulator against the joint, where the protector also includes a channel for receiving injection and/or control tubing. The insulator is capable of reducing heat loss through the joints of a vacuum insulated tubing string by as much as 95%.
