When removing steel pipe from the well, stop at each pipe joint and unscrew the pipe from the fitting. Place the loose joint well out of the way before lifting the next joint. Use a hacksaw or PVC cutter to separate joints in PVC pipe. Cut pipes at least 2 inches away from existing joints if you intend to reuse the existing pipe.
Nearly every welded tube mill employs a scarfing tool to remove the OD weld bead created by the forge-welding process (see Figure 1). The purpose of removing the weld bead is to leave a perfectly smooth surface; the weld zone should be visually indistinguishable from the parent material.
Weld bead scarfing (cutting, removing, and disposing) exposes mill operators to numerous hazards, including cuts and burns from the scarf. Part I of this article discusses the reasons scarf is removed from tube and the mill parameters that affect the scarf removal process. Part II discusses a variety of manual and automated removal and disposal methods.
Jan 26, 2015· I'd like to remove the weld from inside a piece of 2" sch 40 steel pipe. The end result will be an air cylinder. Before anyone says don't do it or buy some DOM, this has to be done on the cheap (read free!) I'll be making something like 5 or 6 of them to use on a "Mad Max" vehicle.
Mar 05, 2018· The type of glue you use to join PVC pipes is called "solvent weld," and these two words tell you the reason why it's 99 percent impossible to separate pipes once they are glued together. This type of glue isn't a surface coating; it's a PVC solvent that actually melts plastic. When you spread this glue on a pair of pipes and join them, the melted plastic of both pipes hardens into a single piece.
Flash Removal During manufacturing of steel pipe and tube, the electric resistance welding process extrudes a small amount of metal (weld flash) on both the inside (ID) and outside (OD) of the tube. The outside flash is always removed from the OD of the tube with a cutting tool which keeps the surface smooth and uniform.
