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 [...]

In addition, we will discuss the benefits of converting material handling equipment from traditional methods toan eco-friendly option, fuel cells using stainless steel seamless tubing. […]
Chromatography is a system of separating the components of a mixture by differential movement through a two-phase method, where relative amounts of each solute are first distributed between a moving fluid stream, and then they enter a contiguous stationary phase. The quality of capillary tubing used affects the efficiency of the flow. High-performance liquid chromatography (HPLC) is a technique in which components of a mixture are separated to recognize and to quantify each element in the mixture. HPLC utilizes pumps to pass a pressurized liquid solvent containing the sample through a column. The column is filled with a solid adsorbent material. Based on the way the adsorbent material reacts to the different components, there are different flow rates, which cause separation as they flow through the column. HandyTube’s capillary tubing with Chromat I.D. has been designed to increase measurement speed and accuracy without sacrificing quality. The smooth-bore offered on capillaries limits Newtonian flow through the sample loop, resulting in a better sample read. Careful quality control during tubing manufacturing, both in-process and at final inspection, are essential for accuracy of size, soundness of material and a uniform inner surface. Flow rates are key to identifying different elements in a solution, so surface finish is a crucial component of quality tubing for HPLC equipment. Known as the “wall effect,” particles move faster through the center of the flow path than those against the wall. A highly polished interior surface of the tubing can increase efficiency and reduce this effect. Product cleanliness is critical in this industry. Impurities, such as oil, grease and other foreign material leftover from the manufacturing process can result in cross-contamination and inaccurate sample readings, or even component failure. Conventional tubing typically requires additional cleaning on-site, prior to installation. Chroma Clean ID™ is a superior cleaning process for ultra-small diameter tubing that removes contaminants that standard cleaning processes leave behind. Filter after typical cleaning process Filter after Cleaning with Chroma Clean process Ultra-Small Diameter tubing holds tight dimensional controls and is engineered with an outer diameter less than 0.0625”. Close tolerances are held on the outer and inner diameters for more accurate measurements and a better seal when using ferrules. As Ultra-Small Diameter Tubing continues to evolve, it will be an important scientific component in analyzing solutions for the medical, legal, research and manufacturing fields. […]
Chromatography is the science of separating components within a mixture into their constituent elements then measuring and analyzing these elements. “High-performance liquid chromatography” (HPLC) equipment can assist in finding water pollution, toxic chemicals, and airborne impurities. Long lengths of small diameter stainless steel capillary tubing is used to plumb many high-precision systems to increase sampling efficiencies. […]
The most common seamless stainless steel tubing is the 300 series of alloys, which are available in varieties of high-performance, corrosion-resistant types and sizes. These stainless steel alloys most commonly include chromium, nickel, molybdenum and titanium, and are ideal for seamless coil tubing because they are easy to maintain and can withstand high pressures and temperatures.
