From the forming process, the tee can be roughly divided into three stages: (1) Filling stages: the pipe is put into the mold cavity, then the mold is closed; the pipe is injected with liquids, and the gas is removed. The two ends of the pipe are pressed with a horizontal punch at the same time. (2)...

Abstract: The eccentric reducer is a kind of pipe fitting used for changing the diameter of the pipeline, which is one of the common pipe fittings in the pipeline system. The eccentric reducer is generally used on the inlet and outlet pipes of the pump. Its main functions are to prevent cavitation...

Reducers A reducer is an important part of the pressure pipeline, which is a common component for connecting pipelines in petroleum and petrochemical equipment. It is mainly used for connecting two pipes with different diameters. A reducer can change the pipe diameter, adjust the...

A pressure pipeline, as one of the main special pressure bearing equipment for transporting various fluid media, has gradually gotten into our industrial production and people's lives, and can be seen everywhere in various industries. Restricted by the unique working conditions of...

Calculation and analysis of thrust force of pipe systems to pipe ends connected to tees When the sliding bracket is hindered or can be operated, the comparison results of the thrust and torque of the pipe system to the pipe end connected to the tee are shown in Table 3. In the table, Fx, Fy,...

The main steam pipe is an important part of the boiler steam and water system, and its stress is complicated at the tee and its connecting part, which is the weak part of the main steam pipe. A certain power plant has been operating for 8×104 hours. Cracks were found at the tee of the...

A pipeline, as an economical, effective, and environmentally friendly transportation method, is currently mostly used for the transportation of liquids and gases. However, leakages often occur in real life. The leakage of the pipeline may be caused by the selection and use of flanges or...

2.2.2 Testing and analysis of metallographic structure of sampled pipe caps Three samples were taken, two of which had fractures. The cross-sections of the samples were pre-ground, finely ground, ground and polished with water sandpaper and metallographic sandpaper, and etched with a 4% nitric...

Abstract: The failure of pipe caps of high-pressure steam pipelines caused by cracking was analyzed and checked. After the macro inspection of the whole, inner and outer walls, the fracture, and the microscopic metallographic structure and hardness test, the brittle failure caused by ultra-low...

Manufacturing of bends At present, there are two common manufacturing processes for bends in the world. One is hot push and the other is hot bending. If you want to make a bend with a small nominal diameter, the hot push process is generally used, while the hot bending process is...
