DTI-391 Clam Shell Stress Relieving Furnace


Customer directive

Our customer wanted to create an indexing single part flow inert atmosphere production furnace system to match, and seamlessly integrate into, the customer’s entire existing manufacturing process at a production rate of 45 seconds part to part. The customer’s then existing process included inefficient batch furnace staging of parts at this point in the process.


Description

The DTI-391 industrial furnace is used to stress relieve welds on very large header systems used in the power generation industry. This custom oven is a clam shell type design with the two (2) halves hinging in the center of the furnace. The top half is opened manually with the assistance of a crane, and the header is loaded into the furnace. The furnace has tubular heating elements located in the top and bottom halves of the furnace. This allows heat to be supplied to all surfaces of the welds.
