Proper Tubing Selection Improves Chromatograph Performance: As laboratories and instrumentation equipment OEMs continue to drive towards more sensitive and responsive instruments, the smoothness of the inner diameter of HPLC tubing is becoming more and more critical. Most HPLC analytical columns are between 3 and 25 cm long and have an inside diameter of 1 to 5 mm. The particles that pack the columns have a typical diameter between 3 to 5 µm. […]

Firefighters face many dangers in the line of duty. Among the greatest dangers are injury or loss of life from heat exposure or from running out of air.  To access breathing air during a fire, firefighters are trained to use SCBA (self-contained breathing apparatus). The tanks they carry on their backs are their lifeline. If [...]

Specialty seamless stainless steel tubing is used in many applications, including the flow of gas, steam and liquid in harsh environments.  Some manufacturers specializing in this field produce seamless, stainless steel tubing ranging from one inch in diameter to finer than a human hair, and in continuous lengths that can exceed a mile. […]

High precision, seamless stainless steel capillary tubing is used in a wide range of instrumentation measurement applications.  Based on heavy wall, small diameter construction (typically 1/8” or less), this tubing is used in critical applications from nuclear reactors to resistojets in aerospace. […]

Stainless steel 316 instrument tubing frequently used on offshore platforms has a thin chromium oxide protective layer for corrosion protection. However, there are instances where this layer does not provide the necessary protection.  In the presence of chloride or localized pitting the oxide film may be at risk of failure.  In addition, crevice corrosion may [...]

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. Characteristics Seamless 316 tubing offers increased corrosion resistance, because it [...]

There are many factors to take into account when running long lengths of high pressure stainless steel tubing, especially larger diameters (1/2” to 1”).  The conventional method is to weld 20 foot lengths of ‘stick’ tube together.  With proper installation, mechanical fittings can provide a leak free connection. When done properly however, a weld is [...]

Capillaries are essential components for instrument tubing because of the accuracy and reliability needed to allow for consistent results. Capillary tubes are typically 1/16” OD or smaller. They are used by OEMs that make instrumentation devices such as pressure, level, flow or temperature transmitters. Though some capillary applications are as large 1/8th OD, most are of smaller diameters [...]

Reduced Scrap and Lower Installation Costs are Among the Advantages The 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 transfer, gas [...]

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 [...]
