Schedule A Meeting

A twelve-foot diameter 304 stainless steel thick wall duct expansion joint produced by Piping Technology & Products, Inc. is shown supported and braced ready for shipment. Special equipment had rolled the knuckles from ¼” material which is then circumferentially welded. This results in an expansion joint with the minimum stresses possibly exerted and, at the high point of the convolution, its most vulnerable area.
