Tube sheet drilling
Tube sheet is widely used in chemical container, pressure vessel, power generation equipment, boiler, condenser, central air conditioning, evaporator, seawater desalination and other industries with main features of multiple holes, small apertures, dense holes, high accuracy and surface finish requirements in the sheet. BTA drilling tools are more suitable for tube sheet drilling considering production efficiency and holes quality. It is also a trend for selecting drill bits of tube sheet. Both machines and tube sheet quality will significantly influence equipment assembly and performance.
CAEC introduces two types of BTA deep hole drilling Type 5 and Type 6 based on different processing.
Type 6 is a special deep hole drilling for tube sheet, applicable for advanced tube sheet deep hole processing.
Type 5 is for less advanced tube sheet deep hole drilling.
