20.3.1 Any piping that has been terminated by using a blind flange (or by othermeans) and is now "free standing" (cantilevered), shall be securely supported by adjacentpiping or securely braced to the base, so as to minimize pipe vibration.

20.3.2 Major concentrated loads such as produced by valves, pipe risers, branches,etc. should be at or near a point of support (do not support from a valve itself, rather, installsupports on either side of the valve). All pipe connections at the edge of the baseplate shallbe supported at the edge of the baseplate. This includes customer connection points andalso interconnecting piping between matching baseplates.

20.4 System components shall be piped, valved, and installed with clearances andaccessibility adequate to permit operation, maintenance, cleaning, and replacement duringoperation.

20.5 Relief valves shall be piped separately back to the reservoir. Relief valve dischargepiping shall use Class 150 flanges with the size to be the greater of the inlet pipe size or thedischarge relief valve connection size.

20.6 Atmospheric or pressurized drain lines shall slope continuously downward in thedirection of flow at the minimum rate of 1/2" inch per foot. Laterals (not more than one in anytransverse plane) should enter the drain header at a 45 degree angle in the direction of flow,if possible.

20.9 Pipe Support Spacing


Page 12 of 16

20.9.1 Suggested pipe support spacing per ASME B31.1 is as follows:

TABLE 4NOMINALPIPE SIZE

(INCH)

MAXIMUMSPAN(FEET)

1 72 103 124 146 178 19

General Notes for Table 4:(a) Suggested maximum spacing between pipe supports for horizontal straight runs of standard and

heavier pipe at maximum operating temperature of 750 Deg. F(400 Deg. C).

(b) Does not apply where span calculations are made or where there are concentrated loads betweensupports, such as flanges, valves, specialties, etc.

(c) The spacing is based on a fixed beam support with a bending stress not exceeding 2300 psi (15.86M pa) and insulated pipe filled with water or the equivalent weight of steel pipe for steam, gas, or airservice, and the pitch of the line is such that a sag of 0.1 in. (2.5 mm) between supports ispermissible.

On long runs of pipe the clamp spacings should be varied by approximately 15% tobreak-up and change vibration frequency.

20.10 The piping arrangement for temporary strainers in pump suctions, if used, shall besuch that strainer removal will not disturb pump alignment. Where temporary strainers aresupplied between flanges at other than customer connection points, a stainless steel spacerring of the same thickness shall be supplied and wired to the piping near the strainer forshipment. The I.D. of the ring is to match the pipe I.D. and the O.D. of the ring should besuch that it will self-center within the flange bolts. The ring will replace the temporary strainerin the field to maintain the same flange face to face separation, reducing pipe stresses.

20.11 All pumps and drivers are to be aligned before piping and rechecked afterwards inorder to insure that alignment is still within the accepted limits. NOTE: HOLD-DOWNBOLTS MUST BE CENTERED IN HOLES AND SLOTS TO FACILITATE FIELDALIGNMENT.

20.12 The orifice in an air bleed line from a centrifugal pump discharge shall be located atan elevation above the top of the oil reservoir. If more than one pump air bleed line is usedon a console, then they shall be piped completely separate back to the reservoir and theyshall not be combined with instrument bleed orifices.

20.13 A 3/4" NPT pressure tap shall be located, for console test purposes, in thecommon pump discharge piping downstream of the pump discharge check valves.

20.15 Oil cooler piping shall include 3/4 NPS flanged connections for valved vents anddrains on the oil side. Water piping, if supplied, shall include 3/4 NPS flanged vent and drainconnections.

20.16 Oil by-passed to the reservoir from downstream of the filters requires a 30 secondminimum residence time in the by-pass piping to allow for dissipation of potential electricalcharges before the oil enters the reservoir.

20.17 Coupling filters, if used, shall include a valved manual by-pass line with pipingarranged so as to prevent the accumulation of foreign materials.

20.18 Piping shall include high point vents for the elimination of air pockets and low pointdrains to facilitate complete drainage without disassembly of the piping. The high point ventsand low point drains shall consist of a 3/4 NPS pipe section (as short as possible) with aplugged 3/4 NPT gate valve. The short pipe section shall be schedule 80 for either carbonsteel or stainless steel for pressures up to 3150 PSIG at 200 Deg. F.
