AbstractAn electric pipe snubber has an annular housing, fixed to a supporting surface, surrounding a pipe and a plurality of brake means fixed to the housing radially disposed about the pipe, which are biased towards and engage a serrated section on the pipe, and a means for electromagnetically releasing the brake means to permit axial displacement of the pipe relative to the annular housing. The brake means have teeth on the end thereof which mesh with the serrations on the pipe. A pipe support system using a series of the electric pipe snubbers along a length of pipe has a control means which releases the brakes of one of the series of the snubbers while the remainder of the series restrain the pipe from axial displacement.
