MANUFACTURING ASME CODE TANK HEADS

SINCE 1970

PRESCOR specializes in ASME 2:1 elliptical heads and weld caps.  We also manufacture dished only, hemispherical, flanged only and flanged & dished heads. 

Carbon steel heads are fully formed above 1650°F, then allowed to cool and normalize.  Chrome alloy steels are formed at higher temperatures. The original plate mill heat treat cycles are repeated to restore the plate to its original condition.  Stainless steels and most high-nickel alloys are formed at even higher temperatures, then immediately annealed and quenched ("solution annealed").

At PRESCOR, we pride ourselves on quality and on-time delivery.  

All PRESCOR Tank heads are hot-formed, seamless, and descaled (shot blast for carbon and low-chrome alloys, sand blast for stainless steels, high-nickel alloys, and some "exotic" plates).
