This aluminum 6061 round tubing is suitable for use in marine and transportation structural applications. The aluminum, silicon, and magnesium alloy tubing is seamless for a smoother bore than welded tubing. It is corrosion-resistant, weldable, and resists stress cracking, and has a T6 temper (heat treated and artificially aged) for increased strength. This seamless round tubing meets WW-T 700/6 and American Society for Testing and Materials (ASTM) B210 specifications for quality assurance and is suitable for use in applications such as structural tubing aboard ships.
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.
