HE is short for Heat Exchanger (heat exchanger) and stomach is an integral part of its importance and the need to be in any  operation  needs to transfer heat from hot liquid to cold liquid or vice versa. # What is the idea of Heat Exchanger? * In principle, heat is usually transferred from hot materials to cold materials and this lead to a decrease in temperature of hot materials and high temperature of cold materials (the amount of heat lost = heat gained + heat leaked into the atmosphere) * Heat transfer in the heat exchanger is mainly in two ways: 1- Conduction 2- Convection # What is the purpose of the Heat Exchanger? • The main purpose of the use of heat exchangers is to save money ... as the cost of heating crude oil, for example, requires a lot of fuel and energy. In the same unit, oil products need to be cooled before being sent to the tanks (so the two functions can be performed in one heat exchanger or a set of heat exchangers). #Cases of flui...

Difference between Pressure Safety Valve and Pressure Relief Valve: Although freely used interchangeably, these terms differ in the following aspect, ## Pressure Relief Valve - is the term used to describe relief device on a liquid-filled vessel. For such a valve the opening is proportional to the increase in the vessel pressure. Hence the opening of the valve is not sudden, but gradual if the pressure is increased gradually. ## Pressure Safety Valve - is the term used to describe the relief device on a compressible fluid or gas-filled vessel. For such a valve the opening is sudden. When the set pressure of the valve is reached, the valve opens almost fully. PLEASE READ MORE..... Industrial Catalyst And Classification.

What is a Check Valve? The valve that used to prevent back flow  in a piping system is known as a check valve. It is also known as a non-return valve or NRV. The pressure of the fluid passing through a pipeline opens the valve, while any reversal of flow will close the valve. It allows full unobstructed flow and automatically shuts as pressure decreases. The exact operation will vary depending on the mechanism of the valve. Parts of Non-Return Valve: It is consists of body, cover, disk, hinge pin, and seat ring. In the image below you can see the parts of the valve. Types of Valves:- The type of disk will decide the type of valve. Most common types of Check valves are #    Swing Type. +    Top Hinged +    Tilting disk #    Lift Type +    Piston Type +    Ball type #    Dual Plate Type #    Stop Check Valve Application of Check Valve (NRV): Check valves (Non...
