Nick Jacob & Clint Schonacher of Louisiana Cutting used a KMT pump with abrasive water jet nozzle mounted to an ESAB cutting table to cut this 72" OD, 3" wall thickness, 516 Gr70 Elliptical Head.

The Elliptical Head is for a 6' OD x 10' Seam-Seam Production Separator (Pressure Vessel). 

The 16-1/4" hole was cut 24" off center w/axis parallel to the vessel to accommodate the weld neck flange shown in the pictures.

Nominal thickness for the vessel is 3" which is comprised of a 516 Gr70 shell clad w/ ~1/4" of Inconel Alloy 625. 

Because all work was done in reference
to the vessel's axis actual cutting thickness ranged from 3-1/8" to 6".

 "Waterjet Cutting Offers Unlimited Possibilities"   

                                    
Paul Zuccatto of Advanced Profiles uses KMT HP Components & an ESAB Table for their water jet cutting because of the flexibility of the process and the ability to hold tighter tolerances. It can cut almost anything in any shape resulting in unlimited possibilities!
