WHAT ARE TUBE SHEETS?
In tube-shell exchangers, tube sheets are plates that are perforated with a pattern of holes designed to accommodate pipes. They support and isolate tubes in the tube-shell exchangers or in boilers. Therefore, they come in different sizes and number of holes. Moreover, they support filter elements. A tube sheet can be made with various materials such as metals, plastic, or composites to comply with different temperature and pressure requirements. Tube sheets may be covered in cladding, which acts as a corrosion barrier and insulator. Furthermore, a galvanic anode or a “sacrificial” anode can be installed to prevent the less active tubing material surface from corroding.
Tube sheets may be used in pairs in heat exchange applications or singularly when supporting elements in a filter.
WHAT IS TUBE SHEET DRILLING?
Tube Sheet Drilling is the proper drilling of holes in tube sheets, complying with predetermined hole configurations to suit device requirements. In other words, correct tube sheet drilling is accurately calculated so that the tubes that tube sheets will support can operate as specified. Tube sheet drilling is an important aspect of tube sheet fabrication because getting the holes wrong can mean improper heat circulation.
Who is Best at Tube Sheet Drilling?
At Peters Machine, all tube sheets are programmed and drilled with CNC machining equipment for precision hole layout. This is a recent project and example of a 13′ diameter tube sheet being drilled by our Intimidator 14′ x 21′ drill.
Furthermore, we offer the following:
- Dryer Plate Machining
- Tube sheet CNC reaming
- Pharmaceutical Tube Sheet drilling
- Replacement Tube Sheets
