Keeping hydroforming competitiveASTM A513 (Standard Specification for Electric-Resistance-Welded Carbon and Alloy Steel Mechanical Tubing) is a conventional specification that governs tube for many uses, and hydroformers have been relying on tube made to this standard for many years. However, some hydroformers think that some aspects of this specification aren't appropriate for hydroforming: Some portions of it need to be... Read More... |
One pipe or two?The energy sector is hot right now, and so is pipe production. Finding the optimum material for making pipe for this industry is tricky. Low-alloy carbon steels tend to be strong, but lack corrosion resistance. Stainless steels resist corrosion but lack strength. Cladding low-alloy carbon steel with a thin layer of a corrosion-resistant alloy is a suitable process, one that AWS Schfer has... Read More... |
Forming a new approachAttendees of the fifth Hydroforming Conference and Exhibition, organized by the Tube & Pipe Association, International, and the Society of Manufacturing Engineers, learned that hydroforming technology is not dead yet. Read More... |
Achieving aluminum's mass at steel's costTube traditionally is produced with a constant wall thickness, leaving design engineers stuck with designing tubular parts and unable to optimize them. A tube with variable wall thickness changes all that. This technology allows design engineers to specify the wall thickness in various areas of a tubular component—increasing the wall thickness in bend regions to prevent splitting and... Read More... |

The evolution of tube hydroformingMore than a decade ago, tube hydroforming grew in two directions: low-pressure hydroforming (a patented process) and high-pressure hydroforming. Since then the industry has grown to include all manner of robots, laser cutting systems, punching operations, and so on. Manufacturing consultant Gary Morphy takes us through about two decades of trends and developments and sheds some light on the... Read More... |
