A pipe system includes a first pipe section and a second pipe section arranged, and together defining a total length, along a longitudinal axis. The first and second pipe sections are movable with respect to each other so as to shorten or lengthen the total length. A fixation member clamps a portion of the second pipe section to a portion of the first pipe section. The fixation member includes an insulator which is electrically insulating and passes no electrical current between the first and second pipe sections.

A restraint device assembly that couples adjoining pipes together is provided. The restraint device assembly includes a ring portion having an arcuate inner periphery surface that encircles an outer wall surface of a pipe. The ring includes a first tie rod opening located adjacent a first location and a second tie rod opening located adjacent a second location. The first and second tie rod openings are spaced apart from each other by a first distance. The second ring portion includes a third tie rod opening located adjacent the first location, a fourth tie rod opening located adjacent the second location. The fourth tie rod opening is spaced apart from the third tie rod opening a second distance.
