BIU U-tube heat exchangers, BES floating-head heat exchangers – Example notations: 1. Floating-head type with a tube box and distribution plate; the diameter of the head tube box is DN600, the design pressure for the tube/shell sides is 1.6 Mpa, the area is 90㎡, the tube length is 6 m, and the tube diameter is φ25 for plain tubes. There are 2 tubes on the tube side and 1 tube on the shell side; the material used for these tubes is 09Cr2AlMoRE. The notation for this type of heat exchanger is: BES(X)600-1.6-90-6/25-2REa. 2. Floating-head type with spiral baffle plates; the diameter is DN800, the design pressure is 2.5 Mpa, the area of the plain tubes is 205㎡, the tube length is 6 m, and the tube diameter is φ19 for reduced-diameter tubes. There are 4 tubes on the tube side; the material used for these tubes is 09Cr2AlMoRE, and the same material is also used for the shell. The notation for this type of heat exchanger is: BES(X)LX800-2.5-205-6/19F-4Rea/b
