More Information
Summary:The invention discloses a lower pipeline reinforcing device and method for replacement of cylinders of a turbine. The lower pipeline reinforcing device comprises at least two transverse beams, at least two longitudinal beams and a clamping device, wherein the transverse beams and the longitudinal beams are crossed to define a channel for accommodating a pipeline, and the distance between the transverse beams which are oppositely arranged or the distance between the longitudinal beams which are oppositely arranged is equal to the outer diameter of the pipeline. The clamping device is fixed to the transverse beams or/and the longitudinal beams, is coaxial to the channel, and is used for applying annular clamping force to the pipeline. By means of the lower pipeline reinforcing device and method, the problems that when the high-medium-pressure cylinders of the turbine are replaced, after a lower pipeline is cut, during back-installation, precise assembly cannot be achieved, and the staggering rate is high can be
