{ "item_title" : "Pipe Fitter Math Handbook", "item_author" : [" R. J. Kastner "], "item_description" : "The drawing gives a centerline dimension. The saw needs a cut length.Between those two numbers sits a chain of arithmetic, geometry, and trigonometry: fitting take-outs, offset travel, bend lengths, bolt circles. An error of a fraction of an inch at the layout stage can become a rejected spool or a lost day in the field. Shop rules and charts help, but a rule used without understanding is hard to check, and it cannot be rebuilt when the chart is not at hand.This handbook presents the mathematics of the pipe trades as one connected subject. Each rule, constant, and chart is traced back to the geometry that produces it, so you can see when a shortcut does not apply, rebuild it, and test a result against common sense before the first cut. It starts with fractions and tape measurement and assumes only basic arithmetic.Inside, you will work through how to: Turn centerline dimensions into cut lengths using fitting take-outs and center-to-end dimensionsCalculate simple offsets and rolling offsets, including travel, run, roll angle, and compound anglesFind the developed length of a bend and work out its arc length, tangent length, and gainCalculate miter cut angles and mark branch connections and fabrication templatesLay out flange bolt circles and work through gasket and bolting arithmeticWork out slope, grade, and drainage; pipe weight; test volumes; and material takeoffCheck your own work with complete worked examples and practice problems that come with answers and explanationsFourteen chapters move from trade arithmetic, units, plane geometry, and right-triangle trigonometry through pipe sizes and schedules, fitting take-outs, offsets, bending, miters, slope and grade, flanges, volume and hydrostatic test calculations, thermal expansion, support spacing, and material takeoff. Appendices gather conversion factors, trigonometric values, and offset constants, and a glossary defines the terms as the book uses them.Written for apprentices learning layout for the first time, journeymen who want a dependable reference for calculations they use less often, and foremen and instructors who need to explain a method clearly.This is an educational text on trade mathematics, not a design manual. Example values teach a method and must always be confirmed against the project drawings, specifications, and applicable codes.Open the book, work the first example with your calculator beside you, and start building layout calculations you can explain, check, and repeat", "item_img_path" : "https://covers2.booksamillion.com/covers/bam/9/79/816/286/9798162867753_b.jpg", "price_data" : { "retail_price" : "47.00", "online_price" : "47.00", "our_price" : "47.00", "club_price" : "47.00", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
