SAES-L-105

Piping Line Classes

Part I, supplements ASME B31.4/8 design code and covers the applicable piping defined in SAES-L-100 for non-process facilities such as pump stations, terminals, water treatment and water injection plants, bulk plants, air fueling terminals, tank farms, and wellhead piping. Flowlines, trunklines, transmission lines, cross-country pipelines, and sub-sea pipelines are excluded.

Part II, supplements ASME B31.1/3 design Code and covers the applicable piping defined in SAES-L-100 for process facilities such as steam generation plants, GOSPs, gas plants, NGL plants, off-shore platforms, refineries, and petrochemical plants.

Part III covers utility and nonmetallic piping for process and non-process facilities.

Commentary Note:

The main purpose of this standard is to have consistent piping line classes in Saudi Aramco facilities and not to be the basis for material selection which is covered in other Saudi Aramco Engineering Standards and Materials System Specificiations. The detailed line classes were developed to be aligned with these mandatory requirements. In case of any conflict in the detailed line classes, it shall be addressed to CSD for resolution.

5.2

The latest revision of this standard shall be used to develop “Piping Line Classes” for grass root plants or new facilities within an existing plant. The plant original specifications based on previous revisions of this standard or specific project’s “Piping Line Classes” should be used for maintaining or tie-ins to existing piping facilities provided the original specifications meet applicable code requirements and do not pose a safety hazard.

The below notes are applicable for line classes of Part I (Non-process Facilities) as referenced in the index (Section 9.1) or the detailed line classes (Section 9.3):

1- Note restrictions of use of SS 316 in ISO 15156/NACE MR0175. Use trim 8

(SS 410) in sour services when general corrosion potential s low.

2- The wall thickness calculation is based on the line class corrosion

allowance and 0.72 design factor. The corrosion allowance is included in the pipe and fitting wall thicknesses. For service conditions that require no corrosion allowance per the applicable Code, different corrosion allowances or different design factor, the wall thicknesses are to be calculated accordingly.

3- Schedule of fittings and flanges to be same as pipe. If high strength pipe is used, high strength fitting per MSS SP-75 and high strength flanges shall be used.

4- Equivalent ASTM specifications for the valve body manufactured from plates, bars, or tubular per Table 1 of ASME B16.34 may be used.

5- ASTM A193 Gr. B7 bolts with ASTM A194 Gr. 2H heavy hex nuts may be

used if the bolts will not be subject to low temperature conditions (e.g., auto-refrigeration due to flange leakage). Refer to SAES-L-109 for bolt material selection.

6- Where nonmetallic seats, seals, liners, etc., are used, the manufacturer’s pressure/temperature ratings shall limit the service of this class. If seal welding is required, threaded end valves shall have extended bodies or “swing-out” bodies to prevent damage due to welding heat.

7- Use flanges instead of unions.

8- Fittings and flanges should of same strength as pipe. This would allow

selecting fittings and flanges of the same thickness.

If the bolts have potential for exposure to the sour service, A193 B7M stud bolts, with A194 2HM heavy hex nuts shall be used.

10- API SPEC 6A nominal sizes are between parentheses.

11- The pipe wall thickness shall be calculated in accordance with Appendix K

(high-pressure piping) of ASME B31.3 code.

12- Socket weld joints shall not be used.

Piping Line Classes

10.2 The below notes are applicable for line classes of Part II (Process Facilities) as

referenced in the index (Section 10.1) or the detailed line classes (Section 10.3):

1-

PWHT is required.

2- No copper or copper alloys are permitted.

3-

For hydrogen or hydrocarbons with hydrogen, refer to Nelson chart in API RP 941 to determine the maximum allowable temperature as a function of hydrogen partial pressure such that.

● A value of 350 kPa (50 psi) or 10% whichever is greater shall be added

to the maximum hydrogen partial pressure.

● A value of 28°C (50°F) shall be subtracted from the selected material

curve readings.

4- Dry chlorine is when water content is less than 2,000 ppm. Design shall

follow Chlorine Institute Pamphlet 6.

5- Note requirements of use of SS 316 in ISO 15156/NACE MR0175.

Use trim 8 (SS 410) in sour services when general corrosion potential is low.

6- Note requirements of use of SS 316 in NACE MR0103. Use trim 8

(SS 410) in sour services when general corrosion potential is low.

7- Wet chlorine contains more than 2000 ppm water.

8-

Safety shields are required for flanged connections.

9- The corrosion allowance is included in the pipe and fitting wall

thicknesses. For service conditions that require higher corrosion allowances, the wall thicknesses are to be increased accordingly.

10- Schedule of fittings and flanges to be same as pipe. If high strength pipe is

used, high strength fitting per MSS SP-75 and high strength flanges shall be used.

11- Equivalent ASTM specifications for the valve body manufactured from plates, bars, or tubular per Table 1 of ASME B16.34 may be used.

12- Use flanges instead of unions.

13- ASTM A193 Gr. B7 bolts with ASTM A194 Gr. 2H heavy hex nuts may be used if the bolts will not be subject to low temperature conditions

Piping Line Classes

(e.g., auto-refrigeration due to flange leakage). Refer to SAES-L-109 for bolt material selection.

14- Where nonmetallic seats, seals, liners, etc., are used, the manufacturer’s pressure/temperature ratings shall limit the service of this class. If seal welding is required, threaded end valves shall have extended bodies or “swing-out” bodies to prevent damage due to welding heat.

15- Threaded connections shall not be used in hydrogen services.

16- In oxidizing environments, the maximum temperature for graphite filler material is limited to 425°C. Spiral-wound gaskets for vacuum and catalyst services require 316 SS inner rings.

17- Fittings and flanges with yield strength of 60 ksi or higher should be used if API SPEC 5L Gr. X60 is used. This would allow selecting fittings and flanges of the same thickness.

18- A corrosion allowance is used for the inner pipe to reflect corrosion on the

inner and outer surfaces.

19- Steam jacket to be sized one NPS larger than the inner pipe.

20- Jacket pipe is designed for low pressure steam (maximum 150 psig) with

0.063 in corrosion allowance.

21- Swages, nipples, threadolets and sockolets are rated for jacket pipe.

22- Valves connected to inner pipe must be steam traced.

23- A corrosion allowance of only 3.2 mm may be used for pipe sizes 6” and

smaller.

24- Threaded and socketwelded connections are not permitted in dry chlorine

service, use flanges including connections for: vents, drains, hydrotest, and thermowells.

If the bolts have potential for exposure to the sour service, A193 B7M stud bolts, with A194 2HM heavy hex nuts shall be used.

25- High corrosion allowance of 3.2 mm is specified for this line class as it is

intended for erosive services.

Piping Line Classes

Line Class 1LC0U (Continued)

Notes:

(1) This line class is normally limited to the range of 4 to 30-inch NPS and is used in conjunction with line class

1BD0U or 1BC0U for smaller diameter pipe material.

(2) Pipe fittings with butt welded pipe pups shall be cement lined per 01-SAMSS-005 and installed with sleeve

couplings per Standard Drawing AE-036768 or per approved alternative method.

(3) The raised face shall be removed when matching with flat face flanged valves.

(4) Welding to cement-lined pipe (e.g., branch connections, vents and drains) requires special consideration and must be planned during the design phase. Contact the Materials Engineering Unit in CSD for welding procedures.

(5) For non-process services, see SAES-S series for applicable design code.

(6) Use EPDM lining if no hydrocarbons are present. Otherwise, use NBR lining.

(7) OS&Y style for above ground valves, ISNRS style with stem extensions for buried valves.

(8) Wedge may be solid, double-disc, or rubber lined.

(9)

If either the wafer or lug style is selected, the cement lining in the adjacent pipe must be shaved to accommodate the movement of the disc.

(10) Connections between 12LC0U and 12BD0U or 12BC0U shall be made with an isolation gasket, such as

Pikotek or equal, or a dielectric union to prevent galvanic corrosion. Cathodic protection, if provided, must be on separate circuits for the different materials. Care must be taken to assure that the isolated joint is not short-circuited by pipe supports.

(11) Connections between cement-lined steel pipe and the same size Copper-Nickel pipe shall be made with an

isolated, flanged joint. The raised face of the cement-lined steel flange shall be machined off to accommodate the connection to the flat-faced Copper-Nickel flange.

(12) Connections between a larger cement-lined steel header and Copper-Nickel pipe shall be accomplished with special cement-lined, flanged tees with a 4-inch minimum size branch. The flanged branch connection to the Copper-Nickel pipe shall be isolated. A Copper-Nickel reducer may then be incorporated to obtain the desired pipe size. Welding bosses shall not be used.

bends and valves shall be made to minimize the damaging effects of erosion;

b) The piping shall be adequately supported by means of suitable hangers or supports to prevent

mechanical damage to the copper-nickel alloy pipe;

c) When Copper-Nickel pipe is connected to cement-lined carbon steel pipe systems, insulating flanges or dielectric unions shall be used to prevent galvanic corrosion of the steel. Care shall be taken to assure that the insulated joint is not short-circuited by pipe supports.

d) Solid 90/10 Copper Nickel weld neck flanges shall be utilized in the corrosive splash and spray zone.

These will have to be DC ordered.

(5) Straight male connectors are required to allow connection between pipe and female threaded valves, threads

shall be lubricated with an anti-galling grease (9CAT material number 1000174870).

(6) Solid copper-nickel weld neck flanges rather than composite flanges shall be utilized in the splash zone.

(7) Consideration shall be given to fluoropolymer coated bolts for offshore applications.

(8) The GTAW process shall be used for all copper-nickel wall thicknesses less than 4.75 mm. AWS A5.7 Type

ERCuNi or ERCuNi-1 consumables are required per SAES-W-011. Type ERCuNi filler rod is available (9CAT material number 1000116221).

(9) All copper alloys for valves shall contain a maximum of 16% zinc to avoid dezincification.

(10) All valves shall have a minimum rating of 200 psi.
