High-pressure thick-wall reducing pipe

The high-pressure thick-wall reducing pipe mainly comprises a thick-wall end, a thin-wall end and a middle transition section with a certain length, the wall thickness of the thick-wall end is consistent with the wall thickness of a pipe nozzle of connected high-pressure equipment, the wall thickness of the thin-wall end is consistent with the wall thickness of a connected pipeline or pipe fitting, and the middle transition section is in smooth transition. The length of the transition section can be adjusted according to actual needs. The length of the middle transition section of the reducing pipe can be adjusted according to needs, the reducing pipe can enable the inner wall of the pipeline between the pipeline and an equipment pipe nozzle to be connected smoothly, the reducing pipe is simple in structure manufacturing, field welding construction is achieved, the construction work amount is reduced, the pipeline welding seam quality is guaranteed, the pipeline safety is improved, the construction period is
