Claims
- 1. A method of manufacturing a sealing ring, comprising the steps of:
- nesting a first annular member within a second annular member, the first and second annular members being coaxial and in intimate surface contact with each other along an interface therebetween;
- welding the first and second annular members together at equi-distant intervals, thus forming a plurality of annular weld zones;
- cutting the first and second annular members along the annular weld zones to form a plurality of multi-ply cylindrical bands, each having first and second, weld-sealed opposite ends; and
- forming each cylindrical band into a sealing profile.
- 2. A method of manufacturing a sealing ring according to claim 1, further comprising forming at least one vent hole in the annular member disposed on a side opposite a high pressure side of the sealing ring.
- 3. A method of manufacturing a sealing ring according to claim 1, further comprising cold working and smoothing the weld lines before cutting and after welding.
- 4. A method of manufacturing a sealing ring comprising the steps of:
- nesting a first annular member within a second annular member, the first and second annular members being coaxial and in intimate surface contact with each other, and having mutual opposite axial ends;
- welding the first and second annular members together at the opposite axial ends, thus forming a multi-ply cylindrical band; and
- forming the multi-ply cylindrical band into a seal.
- 5. A method of manufacturing a sealing ring comprising the steps of:
- nesting a first annular member within a second annular member, the first and second annular members being coaxial and in intimate surface contact with each other, and having mutual opposite axial ends;
- welding the first and second annular members together at the opposite axial ends, thus forming a multi-ply cylindrical band; and
- forming the multi-ply cylindrical band into a sealing profile,
- wherein prior to nesting, the method includes forming at least one vent hole in the annular member disposed on a side opposite a high pressure side of the sealing ring.
- 6. A method of manufacturing a sealing ring comprising the steps of:
- nesting a first annular member within a second annular member, the first and second annular members being coaxial and in intimate surface contact with each other, and having mutual opposite axial ends;
- welding the first and second annular members together at the opposite axial ends, thus forming a multi-ply cylindrical band; and
- forming the multi-ply cylindrical band into a V-shaped sealing profile.
- 7. A method of manufacturing a sealing ring comprising the steps of:
- nesting a first annular member within a second annular member, the first and second annular members being coaxial and in intimate surface contact with each other, and having mutual opposite axial ends;
- welding the first and second annular members together at the opposite axial ends, thus forming a multi-ply cylindrical band; and
- forming the multi-ply cylindrical band into a C-shaped sealing profile.
- 8. A method of manufacturing a sealing ring comprising the steps of:
- nesting a first annular member within a second annular member, the first and second annular members being coaxial and in intimate surface contact with each other, and having mutual opposite axial ends;
- welding the first and second annular members together at the opposite axial ends, thus forming a multi-ply cylindrical band; and
- forming the multi-ply cylindrical band into a convolution sealing profile.
