Wuxi changrun produces ultra large diameter tube sheet forgings for hydrogenation reactors   This is the stage when steel ingots are ready for forging and pressing   This is a scene where the steel ingot undergoes several rounds of reheating and forging, and the basically formed 7.8 mete...

Large scale forging is one of the main methods for producing rough forgings and parts in mechanical manufacturing, often divided into free forging, die forging, etc. Compared with other processing methods, forging processing has the following characteristics:   1.Improve the internal structure...

  Floating head heat exchanger is one type of heat exchanger and a common chemical equipment. To understand its working condition, it is necessary to understand its principle and basic characteristics of the equipment at the first, and then understand its operating conditions.   Overview o...

Principles of flange design:   1.When designing gaskets, the gasket load should be controlled as small as possible.   2.When designing bolts, the center circle diameter of the bolt should be controlled as small as possible to obtain the smallest flange torque, following the principle of "m...

Pressure vessels are the most widely used equipment in the petrochemical industry and are one of the main production tools in the industry. Due to process requirements and the need for installation and maintenance of equipment components, it is necessary to install flanges on pressure vessels (such...

Pressure vessels are one of the most widely used equipment in industries such as petrochemicals, light industry, and electricity.
