Flexible hose end fitting assembly
A flexible hose end fitting assembly includes a first portion defining a first fluid passageway and having a first end configured for coupling to a fluid conduit, a second portion defining a second fluid passageway and having a first end configured for coupling to a second end of the first portion and a second end configured for securely affixed to a flexible hose. A gasket is disposed in a groove formed in an interface between the first portion and the first end of the second portion of the assembly, and the first portion and the first end of the second portion of the assembly are securely fastened together by a plurality of threaded fasteners to form a continuous fluid passageway between the fluid conduit and the flexible hose.
1. A flexible hose end fitting assembly comprising:
a first portion of the assembly having a first end configured for coupling to an end of a first fluid conduit and a flanged end comprising a plurality of flanged fingers, the flanged fingers of the first portion of the assembly having a flanged portion extending radially outward;
a second portion of the assembly having a flanged end comprising a plurality of flanged fingers configured to interlock with the plurality of flanged fingers of the flanged end of the first portion, and a second end configured for coupling to a second fluid conduit, the flanged fingers of the second portion of the assembly having a flanged portion extending radially outward;
an inner conduit segment disposed at an interface of the interlocking flanged ends of the first and second portions of the assembly; and
a ring clamp positioned at least partially within a groove formed by the flanged portions of the first and second portions of the assembly, the ring clamp configured to encircle and secure the interlocking flanged fingers of the ends of the first and second portions of the assembly, the first and second portions forming a continuous fluid conduit from the first fluid conduit and the second fluid conduit.
2. The flexible hose end fitting assembly of claim 1 , wherein the first portion of the assembly has a narrow neck section.
3. The flexible hose end fitting assembly of claim 1 , wherein surfaces of a fluid passageway of at least one of the first portion and the second portion incorporates a protective tungsten-carbide coating.
4. A flexible hose end fitting assembly comprising:
a first portion of the assembly having a first end configured for coupling to an end of a first fluid conduit and a flanged end;
a second portion of the assembly having a flanged end configured for interlocking with the flanged end of the first portion and a second end configured for coupling to a second fluid conduit;
a gasket disposed in a groove formed in an interface between the flanged ends of the first and second portions of the assembly;
a collet disposed about the flanged ends of the first and second portions of the assembly; and
an outer reaction collar having a curved inner surface along an axial length of the outer reaction collar and a lip extending radially towards a centerline of the outer reaction collar, the outer reaction collar encircling and in contact with the collet and the lip of the outer reaction collar abutting an end of the collet, thereby securing the collet around the interlocking flanged ends of the first and second portions of the assembly,
wherein the first and second portions form a continuous fluid conduit from the first fluid conduit and the second fluid conduit.
5. The flexible hose end fitting assembly of claim 4 , wherein the first portion of the assembly has a narrow neck section having a length and outer diameter consistent for coupling with a tube clamp supported on a manifold structure.
6. The flexible hose end fitting assembly of claim 4 , wherein surfaces of a fluid passageway of at least one of the first portion and the second portion incorporates a protective tungsten-carbide coating.
7. The flexible hose end fitting assembly of claim 4 , wherein the outer reaction collar causes the collet to tighten around the flanged ends of the interlocking flanged ends of the first and second portions of the assembly.
8. The flexible hose end fitting assembly of claim 4 , wherein the outer reaction collar is in contact with the collet along a full length of the collet when the collet is tightened around the interlocking flanged ends of the first and second portions of the assembly.
