SHELL&TUBE HEAT EXCHANGER
DESIGN AND FABRICATIONA
As its name implies, this type of heat exchanger consists of a shell (a large pressure vessel) with a bundle of tubes inside it. One fluid runs through the tubes, and another fluid flows over the tubes (through the shell) to transfer heat between the two fluids.it can be used for for evaporation, condensation, heating, cooling and heat recover,and is suitable for high pressure applications.GB/T 151,ASME,PED,EAC certificate provided.
Application
This heat exchanger is widely used in chemical industry, power generation, HVAC and refrigeration, oil and gas, compressor cooling, marine applications, pulp and paper, metals and mining, etc.
Product Paramenters
All three types of Shell & Tube Heat Exchangers, including Fixed tubesheet type, U-tube type and Floating tubesheet type, in a variety of metals including Carbon Steel Q235B/Q345R, Stainless Steel 304/316, Nickel Alloy,titanium,graphite etc.
Fixed tubesheet heat exchanger has straight tubes secured at both ends to the stationary tube sheets that are welded to the shell.This kind of heat exchanger is applicable to all services where the temperature difference between the shell and tube is small.
U-tube heat exchanger is a kind of tube and shell heat exchanger, belongs to the petroleum and chemical equipments. This kind of heat exchanger is named after the 'U' shape tube.This kind of heat exchanger has a light quality, is suitable for the situation with high temperature and high pressure.
Floating head heat exchanger is one end of the tubesheet is fixed to the shell, while the other one can "float" freely inside the shell. Floating head heat exchanger is widely used for the service where the temperature is high between the shell and tube bundle, or the dirty service, like the petroleum refinery.
Product details
This heat exchanger is consists of shell,ends,tubesheet,tube bundle,tie rob,spacer pipe,baffle plate etc.
The baffle plate is a plate designed to restrain or regulate the flow of fluid,used for supporting and fixing the tubes in a defined position.
The tie rods and spacer pipes are used to hold the tube bundle together and to locate the shell baffles in the correct position.
DESIGN SOFTWARE
The heat exchanger design by SW6-2011 and PV Elite. Thermal Rating Calculation Software and Pressure Vessel Mechanical Design Software.
WELDING
All welds are completed by professional welders with special equipment welder certificate to ensure the integrity of pressure vessels.,and can use strength expansion and stick expansion.
The heat transfer area range from 0.5 square meter to 300 square meter,the specifications are tailored,please send your RFQ for more details. Meanwhile,we also supply plate heat exchanger,reactor,hot water tank,dissolving tank,alkali tank,vaccum buffer tank,sterilizing tank and CIP system.If you need them please inquire particularly.All of the configuration can be customized according to your requirements.
