4.1 Pressure Longitudinal pressure stesses were calculated using the following equation:

Sg= Pc-o ,

D' - i~

wtere:  ?= : ernal design pressure (psi) d = pipe inside diameter (!n.)

D = pipe outside diameter (in.)

Tae longitudinal pressure stesses resulting from the maximum pressures given in Section 2.6 were combined with gr2vity s= esses calculated as described in Section 4.2 and evaluated against 1.0 S._,

per the stess recuirement of e Normal Condition.

4. 2 Gravity Maximum vertical support spacings were calculated ustng =e criterti dat the maximum g avity displacement :culd not exceed 0.1 inen. Twr medels were considered - a uniformly loaded cad simply supported single span, and a uniformly loaded and simply sucpor.ed single span with a concencated weight located at midspan.

Gravity stresses based on the spacings and mcdels described above were combined with longitudinal pressure stesses and evaluated 2 gainst 1.0 55

, per the stess recuirements of the Normal Condition.

Gravity stes'ses were also evaluated in ecmbication with Icagitucinal pressure stesses and seismic stresses as descrSed in Section 4.3.

Support and nozzle loads due to g 2v!t/ leading were calculated con-sidering the same piping configurations used to evaluate 1 cads due o seismic loading.

A rigorcus spectral analysis na amployed to derive &e recuired pipe design lata for ear cuake icading. In .his analysis, de effects associated witi: dead- ,

veight of_the pipe were ccupied '.nt the seismic affects and evaluated simultnn-ecusly.

In view of de exceedingly large number of pipe cross-sections, weight cases and spectral cases involved, it wculd be impractical to analyze every pipe situ- "

ation. A simplification in the analytical effort was achieved for a given pipe model and spectra by li=iting all pipe cross-sections, regardless of weights,

  • o te same maximum cynnmic deHection. This is equivalent to specifying the same unique set of modal frecuencies and accelerations for all pipe cases.

Cue to $1s soecidcarion. a spectral analysis of any one pipe cross-section wuld be surdcient for deter-4"ing pipe stresses and reactions for all other pipe cross-sections as dese wculd be interrelated for any two cross-sections by proportionality constants. It should be emphasized that this medod is identical to performmg a complete modal analysis for each pipe case and no accuracy is sacridced.

The above method does result in varying degrees of conservatism for differ-ent pipe cases if a single ma.tmum dynamin defection is specided for all pipe cases regarcless of weight, cross-section properties or response spec-tra. This drawback has been removed by separating the pipe cases into separate groups dependent on spectra and weight listed in .4pendix A3 .

These groups consist of varicus combinations of items listed in Sections 2.3 and 2. 7.

A single critical cross-section was selected for each of the g:oups and studied by analyzing various configura: ions (wit changes in directiom that are likely to occur. Support spacing, support loads, and noenie loads were determined from these smdies and used in the above metod to obtain results for other cross-sections within a group. I'nusually hizh support loads, e.g. loads on axial restraints, are not included in this method and are studied separately.

The increased support loads and reduced spans associated with concentrated weights, elbows, tees, etc. were also studied separately.

A displacement criterion allowing maximum 1/2 SSE and 5SE displacements of one inch was imposed on the analysis. This arbitrary criterion was

, adopted to avoid the possibility of excessive displacements causing pipe interferences with other pipes.

2. For anchor motions stich are perpendicular to de axis of the pipe, 6e first span should be checked to determine the adegascy of the Eetbility conmined in the piping. This should be done by using Case 6. In most cases, where the supports being utilised are two directional (guides). all displacemems which are a: plied perpendicular to de pip-ing axis should be combined by SP.SS and evaluated using Case 6. In cases where one directional suppons or snub-bers provide different suppon spans in each of two per-pendicular directions he di. place = ants shculd be evalu-ated individually. See ie Spres belew:

These fac-tors may not be used concurrently, i.e. if factor ft has been applied, do not utilize factor3 f ' if f3has been applied, do notutilize f4 .
b. Determining intermdata values of support loads Support loads may be modified for temperature, material, nrini mn length less than tah'TatM, and applied nent force less than t*IntM values given in the tables. These fac-tors are as described below:

(1) For temperatures less than those given in the tables, support loads may be modified by inctor fa. 3f (ifke f1) is cale'1atari using the closest t*1atM temperamre which is greater ti.sn the actual temperamre. (See - Figure 5.3.'3 f3= T(Actual) OD

(2) For pipe which is constructed of Carben Steel instead of Stainless Steel, support loads may be modified by factor f4: f = 0. 8 4 (3) For piping which has a maximum xdal run length less than g the support load may be reduced by the factor 15* f=L + support span (x) 3 L + support span (z) (4) For piping which has an applied axial force less than the tal'ilat=> L3g, it may recnire an excessive m:=ber of supports to be released 2s smibbers to permit adequa:e thermal e.vansien lc.tbility.

The minimum acceptable span for Schedule 40 piping is tabulated in Table E-6.1 of Appendiz E. These tables are entered wid de value of de applied displacement (2) 2nd de allowable span is taculated. The equation below shows de l basis for these tables and may be used to determine values not tabulated: l

b. Case 7 (i) Stress acceptability is based upon ensunng da:

de span between the support and de elbow ( v - see figure above) on each leg is greater dan me tabulated allowable minimum span. The :abula:ed allowable spans shown in Table E-6.1 of Case 5 is

              .tpplicacle also to Case 7.

(ii) Case'7 is designed to reduce the ccuservatism is de suppor: loads by taking advantage of de Ee:cibility of de elbow. Since me :able uses the same allownble spans as Case 6, no sdd!-

icnal advantage is gained (i.e. , Case 7 <:a:sc:

Additionally, when :he two legs of the included elbow are of unequal lengt, this case must be evaluated by comparing de applied displacement to the shorter leg. Consequently, Case 7 is normally of g eat-est vslue when used on an elbow which has egal spans en each side (see below). x ( l- l I b i b

4. Special Considerations The following special considerations are applicacle 'vhen using cases 6 and 7 for s=ess evaluation.

l

a. When utilizing Cases 6 and 7, applied displacements from all sources should be considered. Thus, if c. piping sys-tem has both thermal anchor motion (TA30 and seis=le anchor motion (SA3I) applied at one end, these shculd be combined prior to the evaluation. Typically, the displace-ments applied perpendicular to the pipe axis will be com-bined using SESS and will be evaluated independently of the displacements applied axially. 1y AT4AM =K d

Pipingwithin de scope of the alternate crimria dat connects to computer analyred piping should be included in de rigorcus ec=pum; analysis to an e:mnt such dat de ccmputer results are valid for de portion requiring compum: analysts and for at least de Srst span of de piping wldin me almrnate crimria sccce.

It is recommended that the " alternate" piping be included for at least two changes in direction from the point where it con-cects to the " rigorous" piping. The " rigorous" pipe analyst shall include as his responsibility the qualification of the first span includ!ng de firsesupport of the " alternate" piping. Dis-placements shall be provided to the " alter"at " pipe analyst at de interface connection so that he can qualify de portion of de "al arnate" piping extending beyond de first suppor . If there are additional supports downstream of the first support on de " alternate" piping that cannot be quallfled by de alter-nate crimria, den dey must also be qualtfled by the "riger-ous" analyst. B. If an " alternate" piping branch connection is not included in the computer analysis of a pipe run, de support spacing on de run pipe must conform to the requirements outlined in this report for de run adjacent to de branch connection or the seismic support spans for two spans on either side of de branch connection should be in de rigid frequency range.
