ABSTRACT:
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%.
