Products DETAILS
Steel Large Diameter Standard Flat Bottom Head Carbon Steel
Steel Large Diameter Standard Flat Bottom Head Carbon Steel
Flat Heads: These heads have flat surfaces, which makes them ideal for applications that demand flat inside surfaces. Flat heads are considered ideal for no pressure applications, when used for pressure applications, these pressure vessel heads may be quite expensive than other heads discussed here. This is why flat heads are mainly used for holding tanks or storage tanks that store materials at no pressure. These heads are also recommended in applications where lower head heights than ASME F&D heads are needed.
