Custom Carbon Steel Heat Exchanger Tube Plate For Dyeing Machine

Tube plate , is drilled on the round steel as slightly larger than the pipe diameter hole , wear the pipe into the weld up fixed , such a role of a kind of accessories .
The precision of the tube plate processing , especially the hole spacing and pipe diameter tolerance , verticality , smoothness are greatly affecting the above-mentioned chemical equipment assembly and use of performance . As chemical equipment , large-scale power plant , the tube plate diameter also becomes more and more big , 4 m - 5 m diameter tube plate are common . Large tube plate is characterized by tube hole number , dense , small aperture , depth , requirement for high precision and smooth finish .

Material
According to the need to use the environment different , use different material , generally use Q345R container plate , pressure vessel , such as secondary non-corrosive medium circulation , using carbon steel composite panels . In strong acid , high temperature high pressure , nuclear energy and other environmental needs of stainless steel , 16 Mn , corrosion resistant materials such as titanium alloy , the application of new type of synthetic material , bring new life to tube plate products .

Processing
For three or four kinds of pressure container tube plate need high accuracy , the traditional machining method is fitter , rocker drill holes . With large-scale chemical container , the diameter of the tube plate is also increasing , the thickness is gradually increasing , tube plate processing also introduced numerical control technology , widely used nc drilling machine drilling holes with radial drill hole processing . Use a processing center for high efficiency and high precision machining is gradually accepted by some large enterprises . Large thick tube plate in nuclear power , desalination, and central air conditioning demand presents the tendency of increasing in the field of heat exchanger .
