What is the pipe size range, per Fluor Daniel standard, for pipe spools that are to be shop fabricated? Ans: 3" diameter and larger <2.1/2" and larger> 2. What is the pipe size range, per Fluor Daniel standard, for pipe spools that are to be field fabricated? Ans: 2" diameter and smaller 3. Define what piping is considered field assembly? Ans: Off-the-shelf components that make-up a piping assembly and do not require cutting and / or welding <If no field fabrication is required> 4. Define what piping is considered rack loaded, per Fluor Daniel standard, and what pipe size ranges is involved? Ans: Piping in the PIPERACK that crosses two or more supports. 3" and larger 5. All shop fabricated piping spools (mark pieces) are shipped from the fabrication shop in a geometry that is defined by length, width, and height. Assuming it to be a box, there are two situations that you must avoid in regard to the box and the mark pieces within. Describe these two situations and describe the undesirable result if you do not avoid them? Ans: Piece mark must fit within the shipping box otherwise it may not be transported. Skewed placement of the piece mark within the shipping box could result in crowding out other piece marks. <Press fit should be avoided to ensure piece mark fits shipping box> 6. Define a field weld (FW) and when it is used? Ans: Field Weld is made somewhere other than the fabrication shop. Used to connect two mark pieces (or components) together 7. Describe three things you must consider when locating a field weld and why they must be considered? Ans: Accessibility: The weld must be in a place that is accessible to the welder Constructability: The weld must be placed so the constructors can position the piece mark prior to welding. Size of spool piece to ensure it fits shipping box and can be transported. Economics: Made in a location that would lessen or eliminate the need for additional scaffolding. Self-supporting so temporary supports are not required during construction. Made on the smaller side of a reducer; preferably made in the horizontal. 8. Describe a field fit-up weld (FFW) and when it is used? Ans: Field Fit Weld is a weld made somewhere other than the fabrication shop. The fabrication shop adds additional length of material to the spool piece. This additional length gives the field variance for adjustment when the location of the connecting point is not known. <May require field alteration> 9. Per Fluor Daniel standard, what is the construction (fitting type) of: Ans: Pipe size range 2 ½" and larger? Butt-weld Pipe size range 2" and smaller? Socket Welded Pipe size range 2" and smaller? Screwed or Threaded 10. What is the minimum (not absolute minimum) distance between welds that Fluor Daniel likes to use? Ans: 3 inches 11. What is the absolute minimum distance between welds (used only as a last choice)?
