Some knowledge points about pressure vessels

Some knowledge points about pressure vessels

In addition to the quality of steel, stress concentration caused by manufacturing and installation defects is also an important reason for the fracture of low-temperature pressure vessels. Especially at low temperatures, the large peak stress at the stress concentration point is superimposed with the overall membrane stress and bending stress of the equipment, causing the local area of the low-temperature pressure vessel to reach a high stress level. Meanwhile, the plastic deformation capacity of steel decreases, and the self-limiting condition disappears at low temperatures, resulting in sudden brittle fracture of the steel.

What is a plate heat exchanger? What are its advantages?

What is a plate heat exchanger? What are its advantages?

With the country's increasing emphasis on environmental protection and energy conservation, the widespread application of central heating systems has significantly reduced coal pollution in urban areas and saved energy. It can be said that this is a great project that benefits both present and future generations. Heat exchangers are crucial equipment in heating systems, serving as a transitional link in heating and central heating projects. Plate heat exchangers play an extremely important role in the development of heat exchangers.

Common malfunctions of heat exchangers and troubleshooting methods

Common malfunctions of heat exchangers and troubleshooting methods

Common faults and troubleshooting methods for heat exchangers are as follows: 1. The fault indicator light of the heat exchanger is on, that is, the yellow indicator light on the control cabinet is on. What should I do? The fault indicator light indicates that the corresponding water pump is overloaded, and the current of the motor exceeds the rated current.

Water treatment equipment enhanced coagulation technology

Water treatment equipment enhanced coagulation technology

Adding excessive coagulants, new coagulants, flocculants, or other agents during coagulation is called enhanced coagulation in water treatment equipment. Water treatment equipment enhances coagulation and flocculation, allowing conventional treatment processes to remove as much organic matter and disinfection byproduct precursors (primarily humic acid and fulvic acid) from the water as possible.

Heat exchanger manufacturers_Key points for selecting heat exchangers

Heat exchanger manufacturers_Key points for selecting heat exchangers

Heat Exchanger Unit Manufacturers_Selection of heat exchanger units requires a thorough understanding of the specifications of the heat exchanger unit. Carefully check each component of the automatic control system, including components, valves, sensors, etc., to ensure that they meet standards, and carefully inspect parts such as temperature controllers, smart transmitters, and automatic switches. The temperature is also a key consideration. The operating temperature of the customer's application generally does not exceed 75℃. If used in the chemical industry, the temperature may reach 300℃.
