The cold mill pilgering process uses ring dies and a tapered mandrel to reduce tube cross sections by up to 90 percent. Because the process relies on large number of small forming steps, the result is tube or pipe that has nearly homogenous material characteristics. It is suitable for every metal.

This article describes how a fabricator can use the advances in modern CAD/CAM software to cut preformed parts quickly on a sophisticated, multiaxis rotary laser. It specifically examines surface data cleanup, conversion, work envelope check, cutting simulation, fixture design and code generation, and fixture cutting and positioning options of newer programs.

Although eddy-current testing is king in the tube production industry, flux leakage is worth a look. Using a small test sample, equipment-maker InspecTech found that for 3.50-in. to 4.00-in. carbon steel tubing with wall thickness from 0.056 in. to 0.100 in., the flux leakage method found more defects and turned out fewer false alarms than the eddy-current method did.

Stampers, precariously squeezed by tight margins, high material costs, and increasing pressure to be leaner, have issued a request: we want our scrap handling operations to be faster, trouble-free, and more productive. Fortunately, the latest generation of scrap handling equipment makes that mission possible. New machinery, trending toward a greater use of invisible forces and high-tech gadgetry befitting a spy thriller, is equipped with sensors, edge-guide systems, automation, and magnetic forces, equipment manufacturers say. In addition, significant improvements have been made to the scrap handling equipment itself to save space, minimize jams, and to keep it moving.
