Keywords:
Tube sheet, drill out a hole with diameter a little bigger than tube from a round steel sheet, penetrated the pipe through the hole, and then fixed by welding. This is normally used for chemical process vessel, such as sheel tube heat exchanger, pressure vessel, boiler, condenser, central air conditioning, evaporimeter and desalination that playing the part of supporting the immonilization lay tubes. The material of mental possess strong rigidness and great thermal conduction.
