Tube plate

Header plate, which is a circular steel plate with holes slightly larger than the pipe outer diameter, serves as a round steel that fixes the pipes and seals the medium in heat exchangers. It is an accessory that allows the pipe to be inserted and welded in place. The precision of the header plate, particularly the spacing between pipe holes, diameter tolerance, perpendicularity, and smoothness, all affect the assembly and operational performance of the listed chemical equipment.
