Numerical Controlled Process of Tube Plate and Baffles on Tubular Heat Exchangers

Abstract

Tube plate and baffles are all important parts in tubular heat exchangers, drilling holes on them is an important and difficult task for factory. The efficiency of traditional process is low and the error is big. Analyzed the holes’ distributing on six shell side routes exchangers, established mathematics model, compiled numerical controlled program with EIA code, realized numerical controlled process of tube plate and baffles on MITSUBISHI machining center. This improved the quality of equipment and lowered the cost.
