This standard is based on the accumulated knowledge and experienceof manufacturers
and users of rotarytype positive displacement compressors. The objective
of this standard is
to provide a purchase specification to facilitate the manufacture and procurementof rotary
type positive displacement compressors for use in petroleum, chemical, and gas industry
services.
The primary purpose of this standard is to establish minimum mechanical requirements.
This limitationin scope is oneof charter as opposed to interest and concern. Energy conservation is of concern and has become increasingly important in all aspects of equipment
design, application, and operation. Thus, innovative energy-conserving approaches should
be aggressively pursued by the manufacturer and the user during these steps. Alternative
approaches that may result in improved energy utilization shouldbe thoroughly investigated
and brought forth.This is especially trueof new equipment proposals, sincethe evaluation of
as opposed to acquisition cost
purchase options will be based increasingly on total life costs
alone. Equipment manufacturers, in particular, are encouraged to suggest alternatives to
those specified when such approaches achieve improved energy effectiveness and reduced
total life costs without sacrificeof safety or reliability.
This standard requires the purchaserto specify certain details and features. Although it is
recognized that the purchaser may desire to modify, delete, or amplify sections
of this standard, it is strongly recommended that such modifications, deletions, and amplificationsbe
made by supplementing this standard, rather than by rewriting or incorporating sections
thereof into another complete standard.
API standards are published as an aid to procurement of standardized equipment and
materials. These standardsare not intended to inhibit purchasers or producers from purchasing or producing products made to other standards.

adversely affect site performance. To minimize the influence
of these factors,the vendor shall review and comment on the
purchaser’s piping and foundation drawings. When specified,
the vendor’s representative shall a) observe a check on the

The circle you have drawn must contain the origin of the polar chart. If it doesn't, the residual
unbalance of the rotor exceeds the applied test unbalance. Proceed with the balancing machine

units:
In U.S. Customary
The April 1988, November 1979, and October 1973 issues
of this standard referred nozzle forces and moments calculations to appropriate NEMA documents with the stipulation
thatthe constants intheequations be multiplied by1.85.
Experience has shown that there has not been
a uniform interpretation of “1.85 times
NEMA.” Therefore, the equations
have been adapted to compressors by identifying all the constants and clarifying that the equivalent
of the exhaust nozzle
in the NEMA calculation is the largest compressor nozzle.
This is usually, but not necessarily,the inlet nozzle.
