Bends allow fluids to flow more easily than through a series of multiple fittings. Not only do tubing systems offer easier installation, but tube bends can save operators time by eliminating the need to cut, deburr, and install a new fitting for every simple directional change. Fewer individual components means fewer potential leak points, which can improve efficiency and reduce spills and fugitive emissions. Capital Projects Product Selection Guideīent tubing can provide some significant benefits versus traditional pipe in a variety of industrial fluid systems, including:.Sampling System Problem Solving and Maintenance (SSM).Process Analyzer Sampling System (PASS) Subsystem.Process Analyzer Sampling System (PASS).Sampling System Evaluation and Advisory Services.Fluid System Evaluation and Advisory Services.The pictures below show the final product which in this case will carry hydraulic fluid. Other tubing of the same size and grade was bent with an offset.Ī full size template was made to allow for 100% inspection of the prototypes. JIC (Joint Industry Council) fittings are widely used in fuel delivery and fluid power applications, especially where extremely high pressure is involved. For example, 316 seamless stainless steel tubing 1.5 OD x 0.065 wall (16 ga) was bent with two 90 degree bends into a flat-back U. Process piping is often supplied this way. Cardboard, wood or plastic can be used to protect the tubing during transit.Īfter bending stainless steel tubing, a nut and sleeve can be slid over the ends which then can be flared.
Furthermore, care should be taken to avoid having metal strapping in contact with the stainless parts. The machinery and tooling should be cleaned and prepared to avoid such contamination. Since the application of bent stainless tube often involves products for the pharmaceutical and food industries, care must be taken to avoid carbon contamination of the steel. These are prototypes for a vacuum pick-up tube system in a food processing plant. Recently we bent 8 pieces of 304 seamless stainless steel tubing 1.5 OD x 0.083 wall (14 ga) to a 5.25in inside radius with 81 degrees of arc and with 6in tangents on each end. When the desired radius is very tight, seamless usually bends better. If the bend has a large radius, the tubing can be curved with three-roll benders (also called section benders, profile benders, or angle rolls.) If the bend has a tight radius, the tubing can be bent on a rotary-draw bender through a process called mandrel tube bending.īoth welded and seamless tubing can be curved. A variety of methods can be used for bending stainless steel tubing.
