Tolerances of the precision tubes are in accordance with the appropriate dimensional tables of standards. The usual value for the outside diameter (OD) is less than 0.5% of OD in no heat treatment process used. For the heat-treated tubes, tolerance values are depended upon the relation of the wall thickness and the tube diameter (WT/OD) and are larger (up to a single or twofold). In tolerances of the outside diameter (OD) the allowed deviation of circularity is included. When ordering based on the wall thickness, the tolerance is 10% of the wall thickness. Eccentricity of the precision tube is included in the wall thickness tolerance.

Specification:
This 304L stainless steel round tubing is suitable for transport of fluids and gases in food processing environments. The tubing is seamless for a smoother interior flow and greater burst strength than welded tubing. It has greater corrosion resistance than 302 stainless steel and is annealed to restore formability for bending or flaring. This seamless round tubing meets American Society for Testing and Materials (ASTM) A269 specifications for quality assurance and is suitable for use in applications such as transporting beer, wine, and milk
Metal tubing, also called fractional tubing, is used to transfer liquids, air, or solids, and it is characterized by a round shape and a hollow center. Metal tubing is commonly made with various grades of austenitic stainless steel, aluminum, copper, brass, and titanium materials and their alloys. Construction types include seamless, welded, or welded and drawn. Seamless tubing has no seam or weld point, which enables it to better withstand high pressure and resist corrosion. Welded tubing, made by rolling and welding metal sheet stock, is weaker than and not as rounded as seamless tubing, but it has a more consistent wall thickness for tighter wall tolerances. Welded and drawn tubing, also known as "drawn over mandrel" (DOM), is typically welded tubing that is drawn through a die and over a mandrel to create a smooth inner diameter, which gives the tubing comparable corrosion resistance to seamless tubing while still offering welded tubing's tighter wall tolerances. Compression, vacuum, sanitary, and flared fittings connect tubing or redirect flow in a fluid handling system. Metal tubing is used in HVAC and plumbing systems and for applications in the aerospace, automotive, chemical processing, food and beverage, manufacturing, and medical industries.
