The stainless steel tubing can be used for a variety of corrosion resistant applications in high- or low-temperature conditions. Additionally, hydrostatic test and eddy current test are available when specified by the purchaser. Hardness test shall also be taken to determine the Brinell or Rockwell hardness of the tubes. The flaring test shall be conducted for seamless tubing The flange test and reverse flattening test shall be conducted for welded tubing. Dimensional examination and visual inspection shall be carefully conducted. Inspection and TestsĮach heat lot of the stainless steel tubing shall take PMI and tension test to determine its chemical composition and mechanical properties. Usually electro-polishing(EP) or mechanical polishing (MP) is required to remove the burrs and other imperfections on the tubing surface. The stainless steel tubing is generally provided in bright annealed (BA) or annealed & pickled (AP) conditions unless otherwise specified by the purchaser. The end connection of the tubing can be classified as plain ends (PE), butt welding ends (BW), and threaded/ screwed ends. The unit weight (kg/meter) of stainless steel tubing can be calculated by using the formula: mass = (O.D – W.T) * W.T * 0.0246615 * Length. Typical weights of conventional tubing are available on our website. Especially, the stainless steel capillary tubing, which has very small diameter, is available in sizes under 1/2″ down to 0.050″ (12.7 mm to 1.27 mm) in diameter and wall thickness less than 0.065″ down to 0.005″ (1.65 mm to 0.13 mm). The stainless steel tubing can be provided in length of 2 meters, 3 meters, 4 meters and 6 meters. Sizes, Dimensions, Weights and End Connections Duplex stainless steel: UNS S31803, UNS S32750, UNS S32205.īesides, the tubing materials are also available in some typical non-ferrous metals such as:.The stainless steel tubing can be manufactured from an extensive range of austenitic stainless steels and duplex stainless steels: Sometimes the wall thickness of the tubing is given in gauge number, most commonly in the Birmingham wire gauge ( BWG) system. Its wall thickness may be specified in mm or inch unit. The stainless steel tubing may be hot- or cold-finished in seamless or welded type. TP316.ĭistinguished from stainless steel pipe, the stainless steel tubing, or stainless steel tube, is produced to the actual outside diameter and minimum or average wall thickness specified by the purchaser. Instrowest can help you with product supply, installation, and calibration.SS 316 tubing, O.D = 12.7 mm, wall thickness = 1.0 mm, ASTM A269 Gr.
