ASTM A554 A790 201 304 304L 316L Corrosion Resistant Welded Stainless Steel Pipe

This 316/316L stainless steel dual-certified round tubing is suitable for transport of fluids and gases in chloride environments.

The tubing is welded and drawn for a smoother bore than non-drawn welded tubing and a more consistent wall thickness than seamless tubing. It is alloyed with molybdenum and has higher resistance to pitting and crevice corrosion in chloride environments than 304 stainless steel. 

The tubing is annealed to restore formability for bending or flaring the tubing and has an operating temperature range of -325 to +1,500 degrees F. This welded and drawn round tubing meets American Society for Testing and Materials (ASTM) A269 specifications for quality assurance and is suitable for use in applications such as food and beverage preparation equipment in wash down environments.

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.
