Forged Vessel Connections Advantage :


1)Contour forged close to the finished profile for aligned grain flow ofmaterial, resulting in maximum strength and toughness.
2)Less possibility of distortion from heat of welding.
3)Reduction of total time required for vessel fabrication, therefore speedingup delivery and cash flow of each job.
4)Easier traceability of material, only one piece vs. two or more piecesrequired for “built-up” construction — many times test certificates can be alarge additional hidden cost.
5)“Ready to install” convenience.
6)Larger manway bore diameters — when a 16-inch I.D. is required you onlypay for a 16-inch Forged Vessel Connections nozzle and 16-inch mating components, but if youuse a “built-up” construction you pay for an 18-inch weld neck flange, 18-inch pipe and an 18-inch blind. Therefore you save by not paying for thelarger blind flange gasket as well as the larger or more nuts and studsassociated with “built-up” nozzles, For larger minimum I.D.’s the savingsbecome even greater.

7)Integral reinforcement lowers overall fabrication cost by reducing or eliminating the cost in the following areas:
(A)Purchasing and Expediting: One part vs. pipe, flange, and plate.
(B)Material Handling: One piece to unload, stock, and move to shop forfinal installation.
(C)Inventory Control: Fewer parts to stock, trace, and locate on plant site.
(D)Production Scheduling: Forged Vessel Connections Seamless Schedule System of “Reduce &Eliminate” saves time and money…


(E)Quality Control: Time spent verifying all the material certifications,testing procedures, vendor compliance, accompanying customer inspectors witnessing testing and vendor certificates is reduced.
(F)Sales & Marketing: The on-time shipment and the aesthetic appeal of avessel fabricated using Forged Vessel Connections seamless connections creates an atmo sphere which “Reduces” the sales effort required to obtain the nextorder from your customer.
