What is a Swage or Swedge Block : SwageBlocks.com (1158 words) |
 | Swage blocks are generally thick square or rectangular blocks of cast iron, ductile iron or steel. |
| A swage block is made of cast iron (a metal inferior to steel) and is used for finish sizing hot work that has been forged on the anvil and to shape by bending or for forming sheet metal. |
| Often a wood (swage) block or "stump" is used for dishing hemispherical and spoon shapes. |
| Swage-On Flanges (643 words) |
| The Swage-On process uses a hydraulically-powered, internal swaging tool to expand the pipe end outward into machined ridges on the inside diameter of the flange sleeve, producing a permanent connection that equals or exceeds the pressure rating and structural strength of the existing pipe. |
| The Swage-On connection is formed as rollers on the swaging tool move axially along a mandrel to expand the pipe past its elastic limit and into its plastic range. |
| The Swage-On sleeve-to-pipe connection has an axial tensile strength equal to the yield strength of the pipe.The sealing reliability and structural integrity of the Swage-On connector was demonstrated in tests involving a 6-in ANSI 900 connection using API 5L X52 pipe. |
