Defects of the Inner Surface of the Bend
Posted: 10/08/2022 07:16:36 Hits: 401.3.1 The forming process of the bend Pipe bends are formed by bending the pipe at a certain angle through various machining methods. Compared with the welded bend, the integrally formed bend has no welding seam, and the overall reliability and strength are significantly improved. In addition, when... -

Common Failures of Reducing Tees
Posted: 09/10/2022 07:27:14 Hits: 19If the formed part fails to achieve the specified target function, that means failure, which is mainly caused by the size and shape of the product failing to meet the requirements or the change of the material structure and properties before and after forming. Some failures are beneficial, for example,... -

Forming Processes and Methods of Tees
Posted: 07/26/2022 08:51:27 Hits: 17From 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)... -
How to Find the Lowest & Highest Points of Eccentric Reducers?
Posted: 02/09/2022 05:03:05 Hits: 84Abstract: 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... -
Safety Assessment of Pressure Pipelines
Posted: 01/06/2022 02:48:12 Hits: 21Reducers A reducer is an important part of the pressure pipeline, which is a common component for connecting pipelines in petroleum and petrochemical equipment.
