ASME SA240 SS321 Stainless Steel Heat Exchanger Elliptical Heads
ASME SA240 321 Stainless Steel Heat Exchanger Elliptical Heads
YUHONG Group produce variety of heat exchanger heads according to the drawing of clients, products of many materials, such as of carbon steel, stainless steel, alloy steel! We can do many projects: heat exchanger / boiler projects, marine projects, oil & gas projects etc.
This page is about ASME SA240 SS321 stainless steel elliptical heads. Elliptical heads are curved components used in pressure vessels and storage tanks to form the ends of the vessel. The shape of this head is more economical, because the height of the head is just a fraction of the diameter. Its radius varies between the major and minor axis; usually the ratio is 2:1.
ASME SA240 This specification covers chromium, chromium-nickel, and chromium-manganese-nickel stainless steel plate, sheet, and strip for pressure vessels and for general applications including architectural, building, construction, and aesthetic applications
