Lord Fin Tube--Heat exchanger tube sheet usage

Heat exchanger tube sheet usage:

In the heat exchanger, boiler, pressure vessel, steam turbine, and big central air conditioning industries, the heat exchanger tube sheet is widely utilized.

Mainly used in chemical containers, such as shell and tube heat exchanger, pressure vessel, boiler, condenser, central air conditioning, evaporator, water desalination with the purpose of supporting and fixed boiler tube, metal material the not only has strong rigidity, but also has good heat conduction performance.

Heat exchanger tube sheet material:

Depending on the environment, Using different materials for tube sheet, the general use of Q345R, such as the one or two pressure vessel, no corrosive media flow, using carbon steel composite plate. When it comes to meeting strong acid, high temperature and high pressure, nuclear energy, and other environmental needs, corrosion resistant 16Mn and titanium alloy materials, application of new composite materials, and plate products bring new vitality.

Heat exchanger tube sheet quality judging standard:

The main measure in the tube plate detection process is the hole position, hole tolerance, and inner hole finish, without burr, pull the groove position, and so on. For double tube plate detection, pay more attention to holes, two pieces of tube plate hole cooperation is very important. The general use of CNC drilling machines can ensure. The perpendicularity of the hole is very important with respect to the plate, 300mm above the hole, these large diameter thick and require more sophisticated tools and equipment, and special gantry machining center applications will become more common.
