As an alternative to collar studs, every fourth bolt hole in the tube sheet may be drilled and tapped to the size of the stud bolt. The studs in the threaded holes shall be double nutted on the shell side or provided with machined flats to allow of the tube side nut without rotating the stud. API 660 Standard Gun Drilling Machines for Deep Hole Drilling Molds, Axles Gun Drilling Machines Deep hole drilling machines for injection molds, automotive shafts, rods and axles, and heat exchanger tube sheets LPR Global offers gun drilling machines that create straight and precise holes in the range of 2-32 mm in diameter with a drilling depth of up to 1500 mm. Heat Exchanger:Conical shell and Nozzle Reinforcement 2.5 Tube sheets (TS) Tube sheets are used to support the tubes of heat exchanger at extreme ends. TS are made from round plate piece of metal. Holes are drilled for the tube ends at precise locations and pattern relative to one another. Tube sheets are manufactured from the same range of materials as tubes.

See Fig abc. SHELL AND TUBE HEAT EXCHANGER - Inveno EngSHELL AND TUBE HEAT EXCHANGER DESIGN "PART A" STEAM SHELL AND TUBE HEAT EXCHANGERS The shell and tube heat exchanger (STHE) is the workhorse in the steam world, and it is used in many process steam applications. The design is very flexible to meet the strenuous requirements found in steam and condensate systems. Shell and Tube Heat Exchangers Construction DetailsTubesheets are plates or forgings drilled to provide holes through which tubes are inserted. Tubes are appropriately secured to the tubesheet so that the fluid on the shell side is prevented from mixing with the fluid on the tube side. Holes are drilled in the tubesheet
Introduction:Tube sheet is one of the main components in a shell & tube heat exchanger.Tube sheets also named tube plate,have holes drilled to accept a series of tubes inside of an enclosed tubular pressure vessel.The tube sheet itself serves as a supporting elemen t in heat exchangers and boilers. Tube sheets have different sizes and a series of holes are done to create a place where the TUBE-TO-TUBESHEET JOINTS:THE MANY CHOICES TUBE-TO-TUBESHEET JOINTS:THE MANY CHOICES B. J. Sanders Consultant 307 Meyer Street Alvin, Texas 77511 ABSTRACT After a decision has been made to use zirconium as the material of construction for a shell and tube heat exchanger, one must take into account the process design parameters and other considerations in Tube Sheet, Buffle & Cap Chiller, Heat Exchanger, Shell The tube sheets used in heat exchangers and boilers are often clad with an insulating layer which also serves to protect against corrosion. We can produce products DN15-5000 diameter tube sheet with GB standard, American Standard, the Japanese standard, European standard and non-standard flange.
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.A tubesheet may be
