 Shell
and Tube Heat Exchangers
The shell and tube heat exchanger is fast becoming the most
popular device for the transfer of heat in industrial process applications.
The PS and PW-type U-tube heat exchangers by AIC transfer large
amounts of heat at a relatively lost cost, provide lots effective
tube surface while minimizing the requirements of floor space, liquid
volume and weight and are available in a variety of diameters and
lengths. The PS and PW-type U-tube heat exchangers are designed
for a wide range of liquid to liquid (PW) and steam to liquid (PS)
applications.
Features of the Shell and Tube Heat Exchanger
- U-tube construction
- Units designed for liquid to liquid (PW) and steam to liquid
(PS) applications.
- Available in 2 or 4 pass construction.
- Removable tube bundles for convenience in cleaning and inspection.
- Strong, durable construction with stainless 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 of Shell and Tube
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). s
- 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.
- stainless 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 optimizes media flow for high velocity flow turbulence.
