Chemical services of any kind may require special alloys for corrosion resistance, freedom from metal ion contamination, or both. Bioprocessing applications can have even more stringent requirements, due to the high degree of cleanliness required to convey sterile and non-sterile products or solutions. Tubing and/or piping systems, must, therefore meet these requirements in their fabrication, ...

The Role of Alloying Elements on the Fabricability of Austenitic Stainless Steel Tube Systems.
John C. Tverberg, P.E. Metals and Materials Consulting Engineers Mukwonago, Wisconsin
How many times have fabrication problems developed when a new coil or a new heat of steel is put in production? The problems can be tearing, cracking, scratching, poorer weld penetration, poor electropolished ...

Gas Tungsten Arc Welding (GTAW) is used in the manufacturing of longitudinally welded tubes and as a standard for the installation of tube systems in the semiconductor and phar- maceutical industries. During visual and/or boroscopic inspection of welds small grey spots might be conspicuous, especially in the downslope area of orbital welds. These slag spots are also referred to as oxide islands. ...

Proper selection of the size and materials for a piping system involves several basic design considerations. The first step involves determining whether to use piping or tubing. The next step is to establish the size of the pipe or tube, then to select the proper wall thickness, the surface roughness, and finally the alloy selection based on the environment both inside and outside the tube.
