How Do You Make A Metal Pipe?
A basic part of metal fabrication, making a metal pipe requires a firm grasp of math and knowing the seam required for the pipes application after installation. Heavier gauged pipe used in high-pressure systems or for fluid transfer use a welded seam. Properly rolling the metal will ensure that the finished weld joint will not warp during the welding process. When the weld is complete, the weld is either left intact or ground flush. A pipe with a ground weld can be re-rolled to make the finished pipe seamless and perfectly round. Determine whether the pipe is an outside (OD) or inside (ID) dimension. Enter the ID diameter into the calculator or the OD diameter minus 1/4 (.25). You need to subtract two times the thickness of the sheet metal for an outside dimension. Multiply the diameter by Pi (3.14). For example, multiply 5.75 (5 3/4) by 3.14 to get 18.056. Subtract 18 and convert the remainder to a fraction by multiplying .056 by 16, which equals .896.
