Abstract
A reinforcement insert for use in a coupling components in marine exhaust systems. The insert is generally made of a much stronger material than fiberglass and is inserted within corresponding openings of exhaust system components which are to be coupled. Thereafter, a sleeve and pipe clamps are secured to the exhaust system components and tightened thereon. The inserts prevent fracturing of the coupling area between the exhaust system components and thereby prevent dangerous leakage conditions which could otherwise result in the sinking of a vessel or other undesirable consequences.
Claims2
An apparatus for connecting a first cylindrical conduit to a second cylindrical conduit, said apparatus comprising a first cylindrical conduit having an inner diameter and an outer diameter, a second cylindrical conduit having an inner diameter and an outer diameter;
- a first insert, said first insert being substantially cylindrical and having a first proximal end, a first distal end, a first intermediate portion, and substantially parallel inner and outer surfaces formed about a first longitudinal axis, said first insert surfaces flaring radially outward from said first axis at said first proximal end, said first insert outer surface having a diameter at said proximal end that is greater than the first cylindrical conduit inner diameter but less than the first cylindrical conduit outer diameter;
- a second insert, said second insert being substantially cylindrical and having a second proximal end, a second distal end, a second intermediate portion, and substantially parallel inner and outer surfaces formed about a second longitudinal axis, said second insert surfaces flaring radially outward from said second axis at said second proximal end, said second insert outer surface having a diameter at said proximal end that is greater than the second cylindrical conduit inner diameter but less than the second cylindrical conduit outer diameter;
- an elongate sleeve, said sleeve sized to circumscribe said first conduit and said second conduit;
- and
- a plurality of clamps, said clamps sized to circumscribe said elongate sleeve;
- wherein, in use, said first distal end of said first insert is inserted within an end of said first cylindrical conduit and said second distal end of said second insert is inserted within an opposing end of said second cylindrical conduit thereafter said elongate sleeve is placed over said first and second cylindrical components and said clamps are secured around said sleeve thereby securely connecting said first and second cylindrical conduits.
