26、 Scope1.1 PurposeThis recommended practice (RP) is intended to provide recommended procedures, practices, and checklists for the installation and precommissioning of new, existing, and reapplied machinery and to assist with the installation design of such machinery for petroleum, chemical, and gas i
27、ndustry services facilities. In general, this RP is intended to supplement vendor instructions and the instructions provided by the original equipment manufacturer (OEM) should be carefully followed with regard to equipment installation and checkout. Most major topics of this RP are subdivided into
28、sections of “Installation Design” and “Installation” with the intent being that each section can be removed and used as needed by the appropriate design or installation personnel. 1.2 Life Cycle CostIt is the intent of this document to facilitate machinery installations that will provide the user wi
29、th a reduced overall life-cycle cost of equipment ownership. 1.3 Contractual RequirementsAPI 686 is written such that it can be used as a contractual document between an owner company and an engineering and construction (E also known as a maintenance dropout system.2.6 bolt bound Where any hold-down
30、 bolt is not free in the bolt hole, so that the ability to move the moveable element in a machinery train horizontally or axially is constrained.2.7 breakout spool A short, flanged length of pipe immediately connected to the machinery piping flanges. Lengths vary with the size of the pipe but range
31、from 15 cm (6 in.) to 1 m (3 ft). The purposes of this spool are to facilitate machinery installation, allow piping modification to reduce pipe strain, isolate the machinery, facilitate commissioning activities such as flushing or blowing lines, and allow removal of temporary inlet strainers; also k
32、nown as a dropout spool.2.8 cementatious grout A type of grout material that is portland cement based.2.9 chockplate A solid steel (or alloy steel) plate with a machined top surface that is grouted to a concrete foundation to support and maintain alignment of a machinery structural steel baseplate.2
33、.10 combination misalignment When the centerlines of two adjacent shafts are neither parallel nor intersect. This misalignment is normally described in both angular and offset terms.2.11 condensing service A gas stream that contains a vapor component that may condense to a liquid during startup, ope
34、ration, or shutting-down of a compressor or blower. This may include pure vapors such as refrigerants as well as hydrocarbon gas RECOMMENDED PRACTICE FOR MACHINERY INSTALLATION AND INSTALLATION DESIGN, CHAPTER 11-3streams. When condensate is present in the gas stream, the term wet gas may be used. W
35、et gas may also be used as a synonym to condensing service.2.12 critical service Critical service is typically defined as those applications that are unspared /single-train installations whereby loss of operation would result in significant loss of production, loss of primary process containment, or
36、 threat to personnel safety.2.13 dead-leg A length of piping with no flow.2.14 drop point A vertical section of oil mist distribution piping that is usually smaller in diameter than the main oil mist header. This piping rises out of a tee in the main oil mist header, turns horizontally, and extends
37、downward to the machinery being lubricated. 2.15 elastomeric coupling A coupling that obtains its flexibility from the flexing of an elastomeric element.2.16 engineering designer The person or organization charged with the project responsibility of supplying installation drawings and procedures for
38、installing machinery in a user facility after machinery has been delivered. In general, but not always, the engineering designer specifies machinery in the user facility. 2.17 epoxy grout A type of grout material that consists of a resin base that is mixed with a curing agent (hardener) and usually
39、an aggregate filler.2.18 equipment installer The person or organization charged with providing engineering services and labor required to install machinery in a user facility after machinery has been delivered. In general, but not always, the installer is the project construction contractor. 2.19 eq
40、uipment train Two or more rotating equipment machinery elements consisting of at least one driver and one driven element joined together by a coupling.2.20 equipment user The person or organization charged with operation of the rotating machinery. In general, but not always, the equipment user owns
41、and maintains the rotating machinery after the project is complete.2.21 final alignment The aligning of two adjacent machinery shafts after the measurement of piping-imposed strains on the machinery are verified as being within the specified tolerances. 1-4 API RECOMMENDED PRACTICE 6862.22 flexible-
42、element coupling A type of rotating machinery coupling that describes both disk and diaphragm couplings. A flexible-element coupling obtains its flexibility from the flexing of thin disks or diaphragm elements.2.23 gear coupling A type of rotating machinery coupling that obtains its flexibility by r
43、elative rocking and sliding motion between mating, profiled gear teeth.2.24 general-purpose Refers to an application that is usually spared or is in noncritical service.2.25 general-purpose equipment trains Those trains that have all general-purpose elements in the train. They are usually spared, re
44、latively small in size (power), or in noncritical service. They are intended for applications where process conditions will not exceed 48 bar gauge (700 lb/in.2gauge) pressure or 205 C (400 F) temperature (excluding steam turbines), or both, and where speed will not exceed 5000 revolutions per minut
45、e (rpm). NOTE General-purpose equipment trains have all elements that are either manufacturers standard or are covered by standards such as the following: ASME B73 pumps, small API 610 pumps, fans, API 611 steam turbines, API 672 air compressors, API 677 general-purpose gears, API 674 reciprocating
46、pumps, API 676 rotary positive displacement pumps, API 680 reciprocating air compressors, and NEMA frame motors.2.26 grout An epoxy or cementatious material used to provide a uniform foundation support and load transfer link for the installation of rotating machinery. This material is typically plac
47、ed between a piece of equipments concrete foundation and its mounting plate (see 2.32). 2.27 grout pin A metallic pin or dowel used to tie an epoxy grout pour to its concrete foundation to prevent delamination (or edge lifting) due to differential thermal expansion between the grout and the concrete
48、.2.28 head box A device used to funnel grout into a baseplate grout fill-hole so as to provide a static head to aid in filling all baseplate cavities with grout.2.29 isolation block valve A valve used to isolate a process machine preparatory to maintenance. Also known as a block valve or isolation v
49、alve.2.30 mechanical piping analysis An analysis of the piping connected to a machine to determine the stresses and deflections of the piping resulting from temperature, pressure, and dynamic loadings such as pulsating flow (mixed phased flow). Determination of the type, location, and orientation of piping supports and piping guides results from this analysis.
