ABSTRACT:
Insulating the exhaust pipe of an internal combustion exhaust system by sliding a flexible insulated tube over the exhaust pipe. The tube comprises concentrically arranged inner and outer corrugated stainless steel tubes, with the annulus between the corrugated tubes filled with refractory fiber insulation. The wall thickness of the corrugated tubes is in the range of 0.002 inch and 0.004 inch, which provides the insulated tube with sufficient flexibility to be trained over the angled portions of the exhaust pipe. The contact between the corrugations and the pipe assists in holding the insulated tube in place. The inner tube may extend beyond the outer tube and be flared back to the outer tube to enclose the insulation and facilitate movement of the insulated tube over the exhaust pipe. Alternatively, the insulation may also be sealed by end caps.
