® WorleyParsons <br /> resources&energy <br /> • Scale free piping materials such as cleaned carbon steel, stainless steel or non- <br /> metallic will be used as follows: <br /> Piping applications requiring a high degree of cleanliness generally <br /> including injection water supply piping after strainers, air compressor <br /> inlet piping, miscellaneous lubricating oil system piping,and sampling <br /> piping after process isolation valves. <br /> Lubricating oil piping; carbon steel piping shall be pickled and stainless <br /> steel piping shall be swabbed. <br /> Fiberglass reinforced plastic piping materials will be used only in <br /> applications requiring corrosion-resistant material. <br /> 3.16.3 Piping Materials <br /> Piping materials will be in accordance with applicable ASTM, and ASME standards. <br /> Materials to be incorporated in permanent systems will be new, unused, and <br /> undamaged. Piping materials will be in accordance with the following criteria: <br /> • Steel and Iron Pipe. Carbon steel piping 2-inch nominal size and smaller <br /> will be ASTM A53 or A106, Grade B, SCH 80 minimum. <br /> • Carbon steel piping 3 inch through 24-inch nominal size will be ASTM <br /> A53 Grade B seamless (welded seam pipe shall be used for low <br /> pressure air and water) or A106Grade B, with the indicated grades as a <br /> minimum. Carbon steel piping larger than 24-inch nominal size will be <br /> ASTM A672 or API 5L Grade B or ASTM A 13 9 Grade B. <br /> • Low chrome alloy pipe will be in accordance with ASTM A335 Grades P5, <br /> P11, P22 or P91 seamless or welded. <br /> • Stainless steel pipe will be ASTM A312 Grades TP304, TP304L, TP316, <br /> or TP 316L seamless or welded. All stainless steel piping materials will be <br /> fully solution annealed prior to fabrication. The Type 316 materials will be <br /> utilized for high resistance to corrosion. The Type 30 and 3 16L materials <br /> will be utilized for applications requiring hot working (welding, etc.) and for <br /> additional corrosion resistance at welds. <br /> • Schedule numbers, sizes, and dimensions of all carbon steel and alloy steel <br /> pipe will conform to ASME B36. 10M. Sizes and dimensions of stainless <br /> steel pipe designated as Schedule 5S, 10S, 40S, or 80S will conform to <br /> ASME B36.19M. Schedule numbers, sizes, and dimensions of stainless steel <br /> pipe not covered by ASME B36. 19M will conform to ASME B36.10. <br /> • Alloy Steel Pipe. Steel piping for acid service will be Alloy 20. <br /> Lodi Energy Center 3.3 -20 LEC AFC <br /> 071508 Rev.A <br />
