'''Tube Heat Exchangers''' are commonly used for the transfer of heat in industrial process applications. They are available in a variety of diameters and lengths. The U-tube heat exchangers are designed for a wide range of liquid to liquid and steam to liquid applications. | |||
The shell and tube heat exchanger is constructed using copper tubes and a carbon steel shell. It is manufactured using the most advanced technology available and is specifically engineered for a wide range of applications. Every unit is designed, manufactured and tested to meet the quality requirements of the ASME code: Section VIII Division #1 and ISO 9002. | |||
==Features== | |||
*U-tube construction | |||
*Units designed for liquid to liquid and steam to liquid applications. | |||
*Available in 2 or 4 pass construction. | |||
*Removable tube bundles for convenience in cleaning and inspection. | |||
*Strong, durable construction with copper steel tubes and rugged cast-iron or steel head in standard units. (Optional materials are available). | |||
*Coil and baffle arrangements designed to maximize heat transfer performance. | |||
*Tubes expanded into stationary tubesheet allow for tube expansions and contractions, due to thermal fluctuations, without causing stresses on the joints. Welding tubes to the tubesheet is optional. | |||
==Advantages== | |||
The advantage of the shell and tube design cannot be ignored. Each unit comes with: | |||
*Connections that come in standardized sizes for easy assembly and feature additional thread and surface protection for clean installation | |||
*U-bend tubes expanded into a tubesheet which allow for tube expansions and contractions due to thermal fluctuations. | |||
*Gaskets that are made of high quality compressed fibres which lends to reusability. | |||
*A standard cast-iron or steel head for heavy duty services (also available as a spare part). | |||
*Saddle attaches which make for quick and easy mounting. | |||
*Punched baffles with minimal clearances between tubes guaranteeing correct fluid flow and minimized bypass | |||
*A welded shell protected with high quality paint for corrosion resistance. | |||
*Copper steel tubes which allow for strong, durable performance over a wide range of applications. Unique tube bundle layout (chevron corrugated pattern) minimizes deposit buildup at the edges and optimises media flow for high velocity flow turbulence. | |||
==Applications== | |||
Shell and tube heat exchangers are frequently selected for such applications as: | |||
*Process liquid or gas cooling | |||
*Process or refrigerant vapor or steam condensing | |||
*Process liquid, steam or refrigerant evaporation | |||
*Process heat removal and preheating of feed water | |||
*Thermal energy conservation efforts, heat recovery | |||
*Compressor, turbine and engine cooling, oil and jacket water | |||
*Hydraulic and lube oil cooling | |||
