ASME SA516 Gr.70 Carbon Steel Heat Exchanger Dished Elliptical Heads
YUHONG Group can do many projects: heat exchanger / boiler projects, marine projects, oil & gas projects etc.
And we 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!
This page is about ASME SA516 Gr.70 carbon steel dished heads. Dished heads are curved components used in pressure vessels and storage tanks to form the ends of the vessel. They are shaped like the top of a sphere or a section of a sphere, and their design helps to distribute pressure more effectively than flat ends, making them ideal for containing pressurized liquids or gases.
ASME SA516 This specification covers carbon steel plates intended primarily for service in welded pressure vessels where improved notch toughness is important.

A516-70 plate is a high-strength, low-alloy steel plate that offers an optimum combination of strength, weldability, and notch toughness.
Application
Pressure Vessels
Storage Tanks
Heat Exchanger
Heater exchanger heads are used in the construction of heat exchangers. These heads are crucial components that help facilitate the transfer of heat between two mediums. The application of heater exchanger heads is to enclose and seal the ends of the heat exchanger shell, ensuring efficient heat transfer while containing the fluids or gases within the system.
This allows for the exchange of thermal energy between the two mediums without mixing them, making heat exchanger heads essential in various industries such as chemical processing, power generation, HVAC systems, and more.
