ASTM B381 Titanium Butt welding ring sleeve flange ASTM B381 titanium butt welding ring sleeve flange is a type of flange that is designed to be butt-welded to a pipe, tube, or other equipment. It is made from high-quality titanium material that offers excellent corrosion resistance, high strength, and lightweight properties. The ASTM B381 standard specifies the requirements for titanium forgings used in the manufacture of flanges, fittings, and other components. The butt welding ring sleeve design of this flange ensures a strong, leak-free joint between the pipe and the flange. It is commonly used in applications where a permanent, welded connection is required, such as in chemical processing, oil and gas, and aerospace industries. The ring sleeve provides a smooth transition from the pipe to the flange and eliminates the need for a separate welding neck or slip-on flange. The ASTM B381 titanium butt weldin…
