“In addition to being known for the quality of our products, Bendel is also known for our flexibility,” says Fred Weissbach, Gulf Coast Sales Manager for Bendel. “We work with clients and create solutions that are made specifically for them.”
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.
TEMA gives design rules to calculate the tube sheet thickness, which give similar but not identical results to the rules in ASME. It 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.
