4. DESIGN ENGINEERING PRINCIPLES
4.1 Piping Wall Thickness
All piping component wallthicknesses specified in the individual Piping Material Specifica-tion Line Classes are calculated in accordance with ASME B31. ASME B31.3, based on the
internal design pressure an design temperature ofthe flange rating limits as specified in the respective piping line class.
2. The calculation does not account for an additional loadings imposed, such as thermal loads due to thermal expansion stress range, sustained load due to weight, live loads, an other load-ings other than those provided fo inASME B3 1. ASNIE B31.3.
3. Th wall thickness specified in the Piping Material Line Classes will need to be verified for
vacuum design conditions ifapplicable.
a. Line NP 30 and smaller pipes, which will be subjected to vacuum service, may require wall thicknesses to be increased in order to withstand partial or full vacuum design with-out stiffener rings.
b. This follow-up action must be taken to ascertain that the pipe wall thickness adequacy du to elastic stability concern is ftilly addressed, as soon as the external pressure design
requirement is identified on the Project.
c. Application ofstiffener rings for lines larger than NPS 30 shall be employed when vac-uum design condition is identified.
4. Nominal sizes and wall thicknessesofpipe, as specified inthe Piping Material Specification Line Classes, are in accordance with ASME B36. OM and ASME B36.19M, as applicable.
5. Butt welded fittings not covered by ASME 16.9 shall be determined during C ontractor' detailed design and engineering phase.
a. Internal weld seams ofaustenitic stainless steel reducers shall be ground flush with the adjacent base material an examined for surface discontinuities by means ofliquid pene-trant examination in accordance with ASME Section VIII, Division 1,Appendix 8.
b. External weld seams shall be ground smooth an shall also receive liquid penetrant exam-ination.

Cr-Mo and Stainl ss Ste Piping Systems PIM-SU-5112
4. Pressure/Temperature Ratings
1. Pressure/temperature ratingsofflanged components in sizes NPS 1/2 through NPS 24 are
based on ASME 16.5.
2. Pressure/temperature ratings offlanged components larger than NPS 24 are based onASME 16.47, Series B.
3. Pressure is indicated in psig with temperature in degrees Fahrenheit, unless otherwise speci-fied in the individual Piping Material Line Class.
In Piping Line Classes where valves with soft (resilient) seats are applied, design limits shall be adapted in order to cope with pressure-temperature ratings capability as defined inthe applicable valve standard.
5. All piping classes wall thickness designs are based on respective material flange rating pres-sure-temperature design limitations.
4.3 Design Values
1. Allowable stresses for pipe are derived from ASME B31.3 TableA- or applicable ASME
B31.1 material allowable stress table, in reference to material specifications as mentioned in
the piping classes.
2. Internal pressure calculations for seamless pipe aswell as fo 100% RT welded pipe have been performed based on weldjointfactor E= 1.00 an wall thickness mill tolerance of12.5%.
This results in equal wall thickness requirements for butt welded fittings, such as elbows an tees. For these components not more than 87.5% ofthe nominal wall thickness shall be used, as defined in ASME B31.3 para. 302.2.2.
4.4 Branch Connections
1. Reinforcement requirements for 90 degree branch connections have been sized for internal pressure in accordance with ASME 1331.3para. 304.3.2/3, based on design limits ofthe indi-vidual piping classes.
2. Th Supplier shall be responsible fo checking adequacy ofbranch connections for otherrein-forcement requirements, such as thermal loading du to pipe weights, etc.
3. In each line class, a table is developed in order to provide th proper type ofbranch connec-tion, suitable for the design conditions ofth respective piping material line class.
4. Fo each 90 degree run-branch size relation, an alphabetic character refers to the selected type
ofconnection.
a. Where reinforcement isrequired, branch fittings have been specified by preference. b. In the event that application ofbranch fittings is no feasible due to limited room,
pipe-to-pipe branch connection with reinforcing pa ma be applied.
5.0 GENERAL PIPING DESIGN PRACTICES
1. Pipe, valves, and fittings in sizes 1-1/4", 2-1/2", 3-1/2",5"and 22" shall no be used.
2. Th range ofpipe sizes above 24", ifeconomically justifiable, shall be restricted to the follow-ing line sizes to avoid purchase ofvarious different diameter fittings and short pipe spools:

3. Deviation from these standard pipe sizes shall require Purchaser prior approval.
