The Unified Numbering System, Why Designate a Materials Composition?

The Unified Numbering System (UNS) for Metals and Alloys is an alloy identification system which was jointly developed by the ASTM International (formerly the American Society for Testing and Materials) and the Society of Automotive Engineers (SAE) to provide a means of correlating many internationally used metal and alloy numbering systems administered by various societies, trade associations and manufacturers.  The system provides the uniformity necessary for efficient indexing, record keeping and cross-referencing.

Fabrication of Stainless Steel Medical Tubing, Components & Devices

Fabricated medical precision tubing is used in a variety of devices for minimally invasive medical applications, including surgical tools and instruments, sub-assemblies and components. This precision 316 tubing is primarily used for endoscopic, arthroscopic, cardiac and orthopedic procedures. Small diameter stainless steel tubes may be welded or seamless depending on customer specifications. Manufacturers must be ISO 13485 certified, and specialize in the production of precision fabricated tubular and metal components for these medical device applications.  There are many different types of fabrications, that are each dependent on the specific application and specification.  Final fabricated product usually incorporates the use of precision mechanical machining and non-contact laser equipment.

The Difference in Seamless Tubing

 Seamless, by definition, means “perfectly consistent,” but many people get confused by terms like “seam-free” and “welded-and-drawn” when it comes to selecting tube. Seamless tubing, welded tubing, and seam-free tubing all appear to be consistently free of seams, but a closer examination reveals big differences.

Stainless Steel Coil Tubing Adds Efficiencies & Performance

Reduced Scrap and Lower Installation Costs are Among the Advantages
Reduced Scrap and LoThe use of long-length, stainless steel coil tubing delivers a wide variety of advantages to expanding global markets. Using a truly seamless tubing product adds cost-and-productivity efficiencies and improves product performance. Seamless tubing has been used for many applications around the world, including for  oil transfergas transfer and chemical transfer, alternative fuel, and shipbuilding. One continuous length of seamless tubing can reach 6,800 feet long. That’s more than five-and-a-half times the height of the Empire State Building and two-and-a-half times the height of today’s tallest building, the Burj Khalifa in Dubai!

Seamless Tubing: The Only Choice for Process Automation

In today’s competitive market, it’s imperative to have any advantages in your manufacturing process. With focus on driving costs down and reducing waste through lean activities, something commonly overlooked is the performance of your process control systems. Subject to some of the most severe conditions and abuse and heavily relied on to provide critical data for process control and analysis, the reliability and performance of these systems can help you gain that competitive edge.

Many of the high-tech instruments available for process control utilize seamless tubing for functions from fluid transfer to providing a protective sheath for fragile electrical components. These devices are used to measure pressure, flow, level and temperature in various industries. Due to unique manufacturing processes, seamless tubes are completely homogenous throughout the tube cross-section. Compared to welded tubing, seamless is not limited by the ability to round form and joint strip stock.  Among many benefits, seamless tubing has the ability to be produced with much heavier wall thicknesses and eliminates the risk of failure at a weld seam.
