Cones, Conical Flanged Ends

The choice of a cone can be a practical alternative to a dome, but it also requires skill and know-how to press-form, weld, knuckle, and achieve a good quality finished cone shape. Cones are often used if the material is too thin to press a dome without buckling, and if it is not necessary to acquire a dome shape. 
Global Stainless have proven techniques and experience in the fabrication and knuckling of cones for the top and bottom of tanks, hoppers, and vessels.
