3.0 INTRODUCTION
3.1 Identification of Piping Material Specification Line Classes
1. Piping Specification Line Classes are identified by means of a combination of letters and dig-its similar to that of the system adopted by the Process Industry Practices (PIP) Piping Mate-rial Specification
2. The identifiers are preceded by two Purchaser-specific letters, followed by two digits toindicated flange rating, material applicaiton identifier, applicable corrosion allowance, andjoint construction type. The last two digits are Purchaser-dedicated serial numbers(e.g., CTOICA2S71, CT03CAIS72, CT06SAOS71, etc.)
a. The first two letters "CT"' have been chosen as Purchaser identifier.
b. The second field defines the pressure rating and is comprised of two numbers.
c. The third field defines the piping material with two alphabetic characters.
d. The fourth field defines the corrosion or erosion allowance and is a single digit (number).
e. The fifth field defines the type ofjoint construction with a single alphabetic character.
f. The last two digits will end in "7 1 " for each respective service Piping Specification LineClass.
Whenever there is a major and/or minor technical content revision in the base materialspecification with a compatible but different process service, the subsequent revised docu-ment will be identified and tagged as "72," "73,111174,11 etc. to indicate that it is a separateand unique material specification for its dedicated service.
3.2 Description of Piping Material Specification Line Class
Each Piping Material Specification Line Class normally consists of 3 pages per class. A shortdescription of the contents is given below:
Page 1
1 . Basic design information including applicable Piping Code and edition, piping material, coffo-sion allowance, flange rating on pressure and temperature per applicable material table, hydro-static test pressure, etc.
2. Piping material details on pipe sizes and respective wall thickness, nipples, pipe fittings andtheir associated ASTM Material Codes and Manufacturer Standards.
3. Short material Item Code for each piping component used in the Piping Material Line Class,based on the Company's "Piping Item Description Database Classification Index".

4.0 DESIGN ENGINEERING PRINCIPLES
4.1 Piping Wall Thickness
I . All piping component wall thicknesses specified in the individual Piping Material Specifica-tion Line Classes are calculated in accordance with ASME B3 1. 1 /ASME B31.3, based on theinternal design pressure and design temperature of the flange rating limits as specified in therespective piping line class.
2. The calculation does not account for any additional loadings imposed, such as thermal loadsdue to thermal expansion stress range, sustained load due to weight, live loads, and other load-ings other than those provided for in ASME B3 1. 1 /ASNIE B31.3.
3. The wall thickness specified in the Piping Material Line Classes will need to be verified forvacuum design conditions if applicable.
a. Line NPS 30 and smaller pipes, which will be subjected to vacuum service, may requirewall 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 dueto elastic stability concern is ftilly addressed, as soon as the external pressure designrequirement is identified on the Project.
c. Application of stiffener rings for lines larger than NPS 30 shall be employed when vac-
uum design condition is identified.4. Nominal sizes and wall thicknesses of pipe, as specified in the Piping Material Specification
Line Classes, are in accordance with ASME B36. I OM and ASME B36.19M, as applicable.
5. Butt welded fittings not covered by ASME B 16.9 shall be determined during Contractor'sdetailed design and engineering phase.
a. Internal weld seams of austenitic stainless steel reducers shall be ground flush with theadjacent base material and examined for surface discontinuities by means of liquid pene-trant examination in accordance with ASME Section VIII, Division 1, Appendix 8.
b. External weld seams shall be ground smooth and shall also receive liquid penetrant exam-ination.

4.2 Pressure/Temperature Ratings
1. Pressure/temperature ratings of flanged components in sizes NPS 1/2 through NPS 24 arebased on ASME B 16.5.
2. Pressure/temperature ratings of flanged components larger than NPS 24 are based on ASMEB 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.
4. In Piping Line Classes where valves with soft (resilient) seats are applied, design limits shallbe adapted in order to cope with pressure-temperature ratings capability as defined in theapplicable 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 Table A- I or applicable ASMEB3 1.1 material allowable stress table, in reference to material specifications as mentioned inthe piping classes.
2. Internal pressure calculations for seamless pipe as well as for 100% RT welded pipe have beenperformed based on a weld joint factor E= 1.00 and a wall thickness mill tolerance of 12.5%.This results in equal wall thickness requirements for butt welded fittings, such as elbows andtees. 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.
4.4 Branch Connections
1. Reinforcement requirements for 90 degree branch connections have been sized for internalpressure in accordance with ASME 1331.3 para. 304.3.2/3, based on design limits of the indi-vidual piping classes.
2. The Supplier shall be responsible for checking adequacy of branch connections for otherrein-forcement requirements, such as thermal loading due to pipe weights, etc.
3. In each line class, a table is developed in order to provide the proper type of branch connec-tion, suitable for the design conditions of the respective piping material line class.
4. For each 90 degree run-branch size relation, an alphabetic character refers to the selected typeof connection.
a. Where reinforcement is required, branch fittings have been specified by preference.
b. In the event that application of branch fittings is not feasible due to limited room, pipe-to-pipe branch connection with reinforcing pad may 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 not be used.
2. The range of pipe sizes above 24", if economically justifiable, shall be restricted to the follow-ing 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.
