Protective device for installation of alkene gas pipeline

The utility model provides an alkene gas pipeline installation protection device, which relates to the technical field of alkene gas transportation, and comprises a transition pipe body, the middle part of the top of the transition pipe body is communicated with a buffer pipe, the inner walls of the two sides of the buffer pipe are respectively provided with two guide grooves, the buffer pipe is internally provided with a conical block, and the conical block is provided with an opening. An annular plate is arranged at the position, close to the edge of the top, in the buffer pipe, and guide blocks are fixed to the outer surfaces of the two sides of the annular plate and the outer surfaces of the two sides of the conical block. The problems that most of existing transportation modes are transported through pipelines, when the pipelines are in butt joint or vibration occurs in the pipelines, the butt joint positions of the pipelines can be impacted, pipeline leakage is easily caused due to large instant impact,
