Flanges dimensions

For pipework the purge volume may be taken as 1.5 times the pipework volume. For diaphragm meters the purge volume may be taken as 5 revolutions of the meter. For other meters the purge volume may be taken as 1.5 times the volume of a length of pipe equal to a flange-to-flange dimension of the meter.

ASME/ANSI B16.5, pipe flanges and flanged fittings This standard provides allowable materials, pressure/temperature limits and flange dimensions for standard ANSI flanges. Most ANSI flanged-ended PRVs will conform to these requirements.

As an effect of the bend radii the unfolded dimensions of a blank cannot be determined as the sum of the over measured flange dimensions. The difference between both is referred to as the bend allowance BA). The BA can be determined experimentally. For mild steel the DIN6935 standard also offers a series of heuristic formulas. The standard uses the assumption that the neutral fibre (fibre with no effective strain) is showing...

Valve bodies are also standardized to mate with common piping connections flanged, butt-weld end, socket-weld end, and screwed end. Dimensional information for some of these joints and class pressure-temperature ratings are included in Sec. 10, Process Plant Piping. Control valves have their own standardized face-to-face dimensions that are governed by ISA Standards S75.03, 04, 12, 14, 15, 16, 20, and 22. Butterfly valves are also governed by API 609 and Manufacturers Standardization Society (MSS) SP-67 and 68.

For flanges of nonstandard dimensions or for sizes beyond the scope of the approved standards, design shall be in accordance with the requirements of the ASME Boiler and Pressure Vessel Code, Sec. T11, except that requirements for fabrication, assembly, inspection testing, and the pressure and temperature hmits for materials of the Piping Code are to prevail. Countermoment flanges of flat face or otherwise providing a reaction outside the bolt circle are permitted if... 

Tray dryers may be of the tray-truck or the stationary-tray type. In the former, the trays are loaded on trucks which are pushed into the dryer in the latter, the trays are loaded directly into stationary racks within the dryer. Trucks may be fitted with flanged wheels to run on tracks or with flat swivel wheels. They may also be suspended from and moved on monorails. Trucks usually contain two tiers of trays, with IS to 48 trays per tier, depending upon the tray dimensions.
