Manufacturing standards

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. 

Available sizes range from shelf areas of 0.4 to 67 m" (4 to 726 ft"). These are available in several manufacturers standards, either as system components or with arrxihary gear as packaged systems.

IPS), nominal inside diameter. One example of dimensional comparison for IPS pipe for Schedules 5 and 10 are compared to one standard scale of tubing in Table 2-1. The tubing conforms to ANSI/ASTM A-403-78 Class CR (stainless) or MSS Manufacturers Standard Society SP-43, Sch 5S. 

A= effective discharge area, in square inches (from manufacturers standard orifice areas). 

Note that the wheel diameter of 20.6 in. is probably not found in manufacturers standard units. Therefore, select a standard wheel diameter that is closest to the 20.6 in. and then recalculate by Fan Law 1 the change of that wheel s performance to the desired or necessary conditions just calculated. This can be accomplished by changing speed. Most manufacturers have a standard wheel of 20 in. with the next size being 22.25 in. 

Standard costing is usually thought of in connection with manufacturing production but can be used with advantage in the measurement of the efficiency of supporting plant and equipment. Most readers of this book will already be familiar with the measurement of efficiencies against, for example, manufacturers standards for a specific item of equipment. The standards related to such plant will themselves play a part in setting the production standards mentioned above.
