ASME B73.2:2016 pdf free download.Specification for Vertical In-Line Centrifugal Pumps for Chemical Process.
The nomenclature and definitions of pump components shall be in accordance with ANSI/HI 1.1-1.2 except as noted below.
4.2 AdditionaL Definitions
auxthar piping: includes all piping connected to the pump, seal chamber, packing box, or seal piping plan excluding the main piping connected at the pump suction and discharge flanges. Auxiliary piping includes piping, tubing, and all attached components such as valves, instrumentation, coolers, and seal reservoirs.
in-line pump: an overhung impeller-type pump whose driver is supported exclusively by the pump, and whose suction and discharge connections have a common centerline that is perpendicular to, and intersects, the shaft axis.
non—pr surc—contarnmg izornrettcd parts: rump parts that do not contain or retain pressure and are not wetted by the pumped fluid.
wn-prrssurr-containing retted parts: pump parts that do not contain or retain pressure, but are wetted by the pumped fluid (e.g., wear ring).
pressure-containing zwtted parts: pump parts that contain pressure and are wetted by the pumped fluid (e.g., casing and sealing cover).
prrssure-rrtatnmg non uvtted parts: pump parts that retain pressure hut are not wetted by the pumped fluid (e.g., adapter and fasteners).
sealing corer: refers to seal chamber, universal cover, or packing box.
supplier: manufacturer or manufacturer’s representative that supplies the equipment.
5 DESIGN AND CONSTRUCTION FEATURES
51 Pressure and Temperature Limits
5.1.1 Pressure Limits. Pressure limitations shall be stated by the pump manufacturer. See para. 5.8.3 for auxiliary piping.
5.1.1.1 The design pressure of the casing, including seal chamber or stuffing box and gland, shall be at least as great as the pressure—temperature rating of ASME B16.5 Class 150 flanges or ASME B16.42 Class 150 flanges for the material used.
5.1.1.2 The design pressure of jackets shall be at least 100 psig (689 kPa) gage at 340”F (171°C). Heating jackets may be required for jacket temperatures to 500°F (260°C) with a reduction in pressure corresponding to the reduction in yield strength of the jacket
material.
