Beginning with a solid product, the material is trepanned or bored to the customers wall thickness specification. The trepanning process generates a “core” that is available to be returned back to the customer, or recalculated back into the price, reducing the cost of the tube/pipe.
There are a wide variety of size combinations, OD’s and ID’s, available via the trepanning/boring process.
The trepanning/boring option for a tubular/pipe product is an excellent solution to the problem of nonstandard dimensions that T.I. is able to offers its customer base.
