Industrial Contract Drilling Specialists
In addition to delivery of complete shell and tube sheet heat exchangers, Bendel offers contract drilling services for tube sheets, baffles and support plates. We recently shipped the clad tube sheet shown above, for Alloy Engineering.
Total Approach to Flexibility
Our total approach to flexibility gives you a wide variety of options for using Bendel as your contract drilling resource. We offer tube sheet contract drilling services either as a complete turnkey resource—or we’ll drill your materials.
“In addition to being known for the outstanding quality of our reactors, heat exchangers, pressure vessels, and tanks, Bendel is also known for providing attention to our customers’ individual requirements,” says John M. Jurisich, Business Development Manager, Gulf Coast Region. “We work with clients to create optimal solutions that are designed and fabricated specifically for their applications."
Tube Sheets
Tube sheets less than 4” thick are generally made from plate material. Thicker tube sheets, or for high integrity service, are made from forged discs.
Clad plate is commonly used where high alloy material is required for process reasons. A clad tube sheet consists of a carbon or low alloy backing plate of sufficient thickness to satisfy the pressure vessel design code, with a layer of the higher alloy material bonded onto it by welding or by explosion cladding.
Clad Tube Sheet
TEMA provides design rules to calculate the tube sheet thickness, which give similar but not identical results to the rules in ASME. TEMA also specifies tolerances for tube hole diameter, ligament width and for drill drift.
Different methods are available for the attachment of the tube end to the tube sheet. The most common method is roller expansion where the force produced by an expanding tool deforms the tube radially outward to give a mechanical seal. Welded tube joints can be produced at the “outer” face of the tubesheet or downhole at the “inner” face of the tube sheet.
