The use of machining centers for high-efficiency and high-precision hole processing has gradually been accepted by some large enterprises. The demand for large and heavy tube sheets in the fields of nuclear power, desalination, and central air-conditioning heat exchangers is showing an increasing trend.
In this type of exchanger the tubesheet at the Rear Header end is not welded to the shell but allowed to move or float. The tubesheet at the Front Header (tube side fluid inlet end) is of a larger diameter than the shell and is sealed in a similar manner to that used in the fixed tubesheet design. Tube Inserts and Pipe Ferrule ,Used in Heat Exchangers Tube Inserts and Pipe Ferrule. Tube inserts and Tube ferrules are a metal inserted into the end of a heat exchanger tube to provide protection to the Tube mouth ends of a shell & tube type heat exchanger. The need for this Tube Ferrule arises as all tube failures occur within the first few inches of the heat exchanger tube inlet-end.
A tube sheet is usually made from a round flat piece of plate,sheet with holes drilled to accept the tubes or pipes in a accurate location and pattern relative to one another.The tube sheets are used to support and isolate tubes in heat exchangers and boilers or to support filter elements.Tubes are attached to the tube sheet by hydraulic pressure or by roller expansion. TubeSheets - Alexander Comley UKTubeSheets. Alexander Comley is highly experienced in the manufacture of critical, internal heat exchanger tubesheets. These are manufactured in-house up to 2, 000 mm diameter on our Doosan VTS1620M, a state-of-the-art vertical machining centre with live tooling. One of the most common heat exchangers in service within industrial process

You can also choose from machinery repair shops heat exchanger hub tube sheet, as well as from 1 year, 3 years heat exchanger hub tube sheet, and whether heat exchanger hub tube sheet is none.
ASME Section III Stress Analysis of a Heat Exchanger deep hole drilled heat exchanger tubesheet. Figure 2. Location of the Mis-Drilled Hole The mis-drilled hole is located 42.73-inches from the center of the tubesheet (on the primary side) where the nominal primary side ligament is 0.25-inch.
