Liquefied natural gas (LNG) is a new type of clean energy and has been widely used in China recently, which has promoted the development of LNG in this country. In the development of liquefied natural...

Oil and gas storage tanks will continuously accumulate heat at high temperatures, resulting in rapid temperature rise on the surface and inside. In order to solve the problem of internal pressure increase...

Large storage tanks are widely used in petroleum, chemical industry, natural gas exploitation and other energy fields, and are important devices for storing strategic energy materials. The safety and...

With inspection at different stages of the manufacturing process, the inspector examines the work and documents the inspection results. The inspection range of heat exchangers is listed below: (1) Identification...

The purpose of the pressure test after maintenance is to check whether the heat exchanger has the ability to withstand the design pressure safely (i.e. the compressive strength), the tightness, the quality...

How to stipulate the maintenance cycle of shell and tube heat exchangers? According to the requirements of "Pressure Vessel Safety Technical Supervision Regulations", combined with the production...

What are the causes of the internal leakage of the tubular heat exchanger? The internal leakage of the heat exchanger may have the following reasons: (1) The heat exchange tube is corroded, perforated,...

What are the leaking situations of the heat exchanger? The heat exchanger leaks due to cracks and perforations caused by fluid medium corrosion, wear, scouring, assembly strain, defects in the tube itself,...

What combined load may make the fixed tube sheet heat exchanger fail to meet the strength conditions, and use other forms of heat exchangers (such as U-shaped tube type)? Under the combined action...

How to maintain the tube sheet gasket? Under normal circumstances, horizontal placement can prevent deformation or damage. Why do the gaskets on both sides of the tube plate have to be of the same material?...

How do the bolt fastening sequence of heat exchanger tube boxes and tube plates perform correctly? Generally, diagonal bearing and cross-bearing are adopted for fastening, and a torque wrench is used...

What are the causes of severe heat exchanger vibration? （1）Resonance caused by medium frequency （2）Resonance caused by external pipe vibration How to deal with severe vibration of heat exchangers? （1）Changing...
