DESIGN ENGINEERING PRINCIPLES
4.1
Piping Wall Thickness
All piping component wall thicknesses specified in the individual Piping M aterial Specification Line Classes are calculated in accordance with ASME B3 1. ASME B31.3, based on the internal design pressure an design temperature of the 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 loadings other than those provided fo in ASME 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 if applicable.
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 without stiffener rings.
4. 5.
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 of stiffener rings for lines larger than NPS 30 shall be employed when vac-
is identified. condition designand Nominal uum sizes wall thicknesses of pipe, as specified in the Piping Material Specification Line Classes, are in accordance with ASME B36. OM and ASME B36.19M, as applicable.
Butt welded fittings not covered by ASME detailed design and engineering phase.
16.9 shall be determined during C ontractor'
a.
Internal weld seams of austenitic stainless steel reducers shall be ground flush with the adjacent base material an examined for surface discontinuities by means of liquid penetrant 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 examination.

Pressure/Temperature Ratings 1.
Pressure/temperature ratings of flanged components in sizes NPS 1/2 through NPS 24 are based on ASME 16.5.
2.
Pressure/temperature ratings of flanged components larger than NPS 24 are based on ASME 16.47, Series B.
3.
Pressure is indicated in psig with temperature in degrees Fahrenheit, unless otherwise specified 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 in the applicable valve standard.
5.
4.3
4.4
5.0
All piping classes wall thickness designs are based on respective material flange rating pressure-temperature design limitations.
Design Values 1.
Allowable stresses for pipe are derived from ASME B31.3 Table A- or applicable ASME B3 1.1 material allowable stress table, in reference to material specifications as mentioned in the piping classes.
2.
Internal pressure calculations for seamless pipe as well as fo 100% RT welded pipe have been performed based on weld joint factor E= 1.00 an wall thickness mill tolerance of 12.5%. This results in equal wall thickness requirements for butt welded fittings, such as elbows an tees. For these components not more than 87.5% of the nominal wall thickness shall be used, as defined in ASME B31.3 para. 302.2.2.
Branch Connections 1.
Reinforcement requirements for 90 degree branch connections have been sized for internal pressure in accordance with ASME 1331.3 para. 304.3.2/3, based on design limits of the individual piping classes.
2.
Th Supplier shall be responsible fo checking adequacy of branch connections for otherreinforcement 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 of branch connection, suitable for the design conditions of th respective piping material line class.
4.
Fo each 90 degree run-branch size relation, an alphabetic character refers to the selected type of connection. a.
Where reinforcement is required, branch fittings have been specified by preference.
b.
In the event that application of branch fittings is no feasible due to limited room, pipe-topipe branch connection with reinforcing pa ma be applied.
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 of pipe sizes above 24", if economically justifiable, shall be restricted to the following line sizes to avoid purchase of various different diameter fittings and short pipe spools: 30", 36", 42", 48", 56", 64", 72", 84", and 96".
3.
Deviation from these standard pipe sizes shall require Purchaser prior approval.
