Problems solved by technology

Therefore, when the pipe is installed and welded, cracks often occur at the butt weld between the end of the elbow and the pipe. Concentrated on the arc tangent line, when the stress is released, it is easy to cause cracks in the welding part, and because the flow velocity and pressure are relatively high in the bending part of the pipeline, the life of the bending part is reduced, and the unpredictable situation of the bending part makes the maintenance work easier. extremely inconvenient

Abstract

The invention discloses a butt welding seamless alloy steel high-temperature high-pressure elbow with straight pipe sections, and relates to the field of transportation pipelines. The elbow comprises a pipeline, a flow speed sensor, a pressure sensor and a display device. The pipeline comprises the first straight pipe section, a bent section and the second straight pipe section. The first straight pipe section and the second straight pipe section are located at the two ends of the bent section correspondingly and fixedly connected with the bent section. The flow speed sensor is located at the end, close to the first straight pipe section, of the bent section, one end of the flow speed sensor is connected with the bent section through a circuit, the other end of the flow speed sensor is connected with the display device through a circuit, the pressure sensor is located at the end, close to the second straight pipe section, of the bent section, one end of the pressure sensor is connected with the bent section through a circuit, and the other end of the pressure sensor is connected with the display device through a circuit. Convenience can be brought to a pipeline construction site and pipeline welding, the flow speed and pressure in the pipeline can be measured and controlled in real time, and pipe maintenance work is facilitated.

Description

technical field [0001] The invention relates to the field of transportation pipelines, in particular to a butt-welded seamless alloy steel high-temperature and high-pressure elbow with a straight pipe section. Background technique [0002] Process piping and power piping systems in the petroleum, chemical, electric power, and nuclear power industries use alloy steel high-pressure seamless elbows due to high-temperature and high-pressure operating conditions. The alloy steel high-pressure seamless bends currently used are all long-radius elbows without straight pipe sections. Therefore, when the pipe is installed and welded, cracks often occur at the butt weld between the end of the elbow and the pipe. Concentrated on the arc tangent line, when the stress is released, it is easy to cause cracks in the welding part, and because the flow velocity and pressure are relatively high in the bending part of the pipeline, the life of the bending part is reduced, and the unpredictable...
